The origin of a patient’s dental wear may be deceiving. Is it physiological or pathological? This minor difference could spell major consequences for the lifetime oral health of your patients. We care about understanding the differences and how to manage them for the benefit of our patients. 

What is the amount of normal tooth wear? 

To understand normal tooth wear, let’s compare the size of teeth at age 10 to their size at age 70. Based on extensive research, we’ve found that the average loss of tooth structure over this 60-year period is approximately: 

• 1.74 millimeters on posterior teeth (first molars) 

• 1.01 millimeters on upper anterior teeth (centrals and laterals) 

This equates to roughly 15-26 microns of wear per year, depending on the tooth type. 

It’s important to note that this includes all forms of wear, such as attrition, erosion, and abrasion. Even with this normal wear, most people should still have a layer of enamel on their teeth at age 70. In fact, you might expect to retain at least half of the original enamel thickness on your incisal edges and cusps. 

While a certain amount of tooth wear is a normal part of aging, it’s important to distinguish between physiologic wear and pathologic wear. Physiologic wear is a natural part of aging and includes abrasion, erosion, and attrition. It occurs at a predictable rate and typically does not result in significant tooth structure loss. If you notice excessive tooth wear beyond the expected range of 15-26 microns of wear per year, it may be a sign of an underlying issue that requires further evaluation. 

What is the patient-centered approach to discussing wear and understanding the cause of tooth wear? 

When discussing tooth wear with patients, it’s essential to approach the conversation with empathy and understanding. By using a patient-centered approach, you can foster open communication and encourage patients to take an active role in their oral health care. 

• Open-Ended Questions: Ask open-ended questions to encourage patients to share their observations and experiences. For example, you might say, “I’ve noticed some wear on your teeth. Have you noticed any changes in how your teeth feel or look?” 
• Avoid Assumptions: Don’t jump to conclusions about the cause of tooth wear. Instead, ask questions to gather more information and explore potential contributing factors. 
• Emphasize Collaboration: Emphasize that you’re working together to identify the cause of tooth wear and develop a treatment plan. This fosters a sense of partnership and encourages patient involvement. 
• Avoid Blame: Avoid blaming the patient for tooth wear. Instead, focus on identifying the underlying causes and developing strategies for prevention and treatment. 

What do I say to my patients? 

I always start from a place of curiosity. I might say, “When I examine your teeth, I notice some wear that seems more than what’s typical for your age. I’m curious if you’ve noticed any changes in how your teeth feel or look. Sometimes, unusual wear can be a sign of underlying issues like teeth grinding, acid reflux, or other factors.” 

Many times, patients will then say to me, “I don’t know. Do you think I grind my teeth?” or “I don’t know. I do have acid reflux.” If the patient says, “Gosh, I don’t know what that’s about,” the next piece of the puzzle is to take my curiosity and help them understand what we would do diagnostically to figure that out and potentially what we would do to manage that. 

If I think the wear is erosive, the conversation can turn to acid reflux or an acidic diet or abrasive toothpaste. If I think it’s erosive, the conversation leads to “seeing if we can learn what your teeth are doing when you sleep at night. If you’re grinding your teeth, that is something we can manage.” 

I never start with “I think you grind your teeth,” or “I think you have acid reflux,” no matter how confident I am that that is the case. I don’t approach it that way for a couple of reasons. I need to give the patient a chance to process that information and come to terms with the fact that something may be going on that they weren’t aware of beforehand. There’s an emotional impact from hearing that information, so we want to deliver it in a gentle way. And I want the patient to become aware of what may be happening on their own. I want to create a co-discovery process.  

The general message is “We can work together to figure out what might be causing this. By understanding the cause, we can work together to determine the best course of action to protect your teeth and prevent further wear.”

We all know that the instrumentation options for dental hygiene services have come a long way since the first dental hygienist scaled teeth in 1906.   Early in the 20th century, the only technology a hygienist had was a set of sharp metal instruments and a spinning brush of gritty pumice. In the 1950s, ultrasonic technology was invented which helped disrupt calculus, but hygienists still had to follow up with scalers and polishers. Similarly, since the days of first scientific articles regarding oral micro-organisms in the 1870’s, our knowledge has increased exponentially regarding the role of oral biofilm not only in oral diseases, but whole-body health.   

In 2021 our office staff attended continuing education courses with legendary periodontist, Dr. Sam Low. Dr. Low introduced our practice to new technology that would help elevate our hygiene practice by improving biofilm removal, increasing patient ownership of personal oral hygiene practices, decreasing damage to root surfaces and restorations, and providing a gentler patient experience.   

The instrumentation is provided though a unit called a Prophylaxis Master – which is a combination of two different treatment modalities.  The hygienist first uses the Airflow unit to remove soft biofilm and young calculus.  The airflow handpiece delivers a combination of water, air and fine erythritol powder to lift and suction away the biofilm as well as stains.  Once the biofilm, young calculus and surface stains are removed, the hygienist moves to the integrated Piezo scaler to gently emulsify the remaining calculus. There are several different tips for both units to access deep pockets and implant surfaces safely. 

Scientific research has demonstrated this system is the gentlest and most efficient way to eliminate bacteria around cosmetic work and titanium implants, on enamel and root surfaces, and even on soft tissues. 

The GBT Protocol 

To get the most out of our investment, we implemented the “GBT” protocol, which is recommended by EMS, the company that manufactures the Prophylaxis Master. The 8-step GBT protocol is as follows:  

1. Assess the teeth, gingiva, periodontal tissues, and any implants and peri-implant tissues. 
2. Use disclosing solution to identify areas of biofilm accumulation. The color will also guide the hygienist to remove the biofilm with Airflow handpiece, after which calculus is easier to detect. 
3. Show the patient the colored biofilm to raise awareness. Spend time educating the patient and emphasizing the importance of prevention. 
4. Removal of biofilm, early calculus and stains with the Airflow. Airflow Plus powder is safe to use on teeth, root surfaces, gums, tongue, and palate. It can also be used to clean dental implants, restorations, orthodontic appliances, and clear aligners. 
5. Use Airflow Plus powder with the Perioflow® nozzle to remove biofilm in >4 to 9mm pockets, root furcations, and on implants. 
6. Remove the remaining calculus, using the minimally invasive EMS PIEZON® PS instrument supra and subgingivally in up to 10mm pockets and clean >10mm pockets with a mini curette. Use the EMS PIEZON® PI MAX instrument around implants up to 3mm subgingivally and on restorations. 
7. After checking to make sure all biofilm and calculus has been removed, diagnosing for caries, and applying fluoride for a fresh and smooth feeling. 
8. Schedule the patient’s recall visit based on risk assessment. 

What Our Patients Love About It  

• Patients trust the thoroughness of the therapy because they can see the disclosed biofilm before it is removed and its absence after it is removed.  

• The therapy is more comfortable than traditional methods. The water is warmed, and there is minimal root surface sensitivity compared to traditional hand and ultrasonic instrumentation.  

• This technology gently reaches into places where traditional instruments couldn’t remove stains and tartar.  

• The education patients receive from our hygienists highlights the value of the therapy.  

• We have found that this is a superior stain and calculus removing technology.  

• The erythritol powder that is mixed with warm water is pleasant tasting.  

 What Our Hygienists Love About It  

• Less hand instrumentation means less body fatigue.  

• There is superior stain removal and visual evidence that the biofilm is completely removed.  

• Patients don’t complain about sensitivity or “poking.”  

 What Doctors Love About It 

• Patients are happier.  

• Hygienists are happier.  

• It eliminates patient complaints about hygienists who are either “too aggressive” or “not aggressive enough” with instrumentation.  

• It prevents damage to cosmetic and implant restorations, as well as root and enamel surfaces.  

Note: We are not paid to promote EMS or Guided Biofilm Therapy. We honestly think this is the best way we can efficiently, comfortably, and thoroughly provide the comprehensive care our patients deserve—and we thought we should share our great experience

Cleaning the larger gingival embrasures around a posterior dental implant can be a challenge for patients. In my practice, posterior implant patients are some of the individuals we give X-Floss samples to try at home.  

X-Floss is a dental floss made by iDontix® that is designed to make flossing easier for individuals with bridges, braces, implants, or larger-than-normal gingival embrasures. It resembles yarn, has a thick texture, and has a hard end, making it easy to push under orthodontic wires, bridges, or in embrasure spaces. It effectively cleans larger spaces while remaining gentle on the gums. The soft material minimizes the risk of injury during flossing, even in subgingival areas, and it is conveniently available on Amazon and in drugstores.  

There are two varieties. Green X-Floss from is too thick for some spaces. Blue X-Floss Lite is less thick and just right for some spaces. You and your hygienist may want to give samples of both to your patients to try. Some of your patients are likely to more effectively and consistently floss once they are using this type of floss.

When you are managing the care of an older patient, I encourage you to take time to look up their medications and the medication you are considering prescribing, even something as simple as antibiotics or pain medication. 

A resource I use when I am writing prescriptions and also managing existing pharmaceuticals that my older patients are taking is the Beers Criteria published by the American Geriatric Society (AGS). The AGS Beers Criteria® lists the Potentially Inappropriate Medications (PIMs) that are typically best avoided by older adults in most circumstances or under specific diseases or conditions.  

Some listed PIMs should not be written for people over age 65 and some are okay with caution or in moderation. There is a long list of medications people can take until they are ages 65 to 70 without a problem. After that age, there are side effects. 

Some of the medications cause adverse reactions on their own or in interaction with other medications. Some of these PIMs are common over-the-counter antihistamines.

My dad and I were enjoying our favorite lunch spot years ago when he turned to me and said, “Laura, isn’t it amazing? There’s an incredible sense of trust that our patients have in us. Sometimes, we give our best recommendation for treatment, and it is declined as if it weren’t important or a priority. I’ve recognized that, more often than not, our patients eventually choose to move forward, proving that it was more a matter of timing and circumstance than lack of value.” 

Trust is the cornerstone of our practice. It was transferred from patients to Grandpa to Dad and to me. I do believe that every morsel is earned through guidance, thoughtfulness, and skill. Trust is an entity that requires constant nurturing. In private practice, one should recognize that a doctor’s trust in their patient is equally as important as a patient’s trust in their provider. With synergy there’s the opportunity for optimal health. Even as a child, I had a very clear understanding of the care my dad had for his patients. This feeling is innate and deeply imbedded in me. I imagine that he felt the same.  

I don’t consider myself “a writer,” but I’ve always enjoyed the art of letter writing. I grew up writing frequently to my grandparents and friends and always loved picking out stationary that reflected my personality. Recently, I reread the letters that my grandfather typed on his old typewriter and my oldest brother scribbled on his Grateful Dead CD inserts – crafted just for me. It seems fitting then that I enjoy writing personalized letters to my patients. In fact, I’m pretty sure I salvaged my mental health during COVID by writing “updates” to my patients during months of closure. I digress. 

The letters that I write to my patients are most often in reference to comprehensive treatment. They provide a bird’s eye glimpse of our most recent findings, diagnoses, and treatment recommendations. My older patients, especially, appreciate my thoroughness, organization, and systematic approach to recommended treatment. These letters certainly aren’t handwritten, but the hard copy renders a sense of care that’s transferred from my hands to theirs. We must remember that individuals comprehend and retain information differently. The one-on-one, verbal, treatment consultation can become lost in the shuffle of everyday. Add dental language and complicated procedures to the mix, and that’s simply a recipe for confusion.  

Whenever I present complex treatment to a patient, I write a letter in everyday language to support our conversation. It’s stored in their digital chart as part of their dental record. In my first paragraph, I state my patient’s chief complaint. A summary of clinical findings followed by bullet point. Next, I provide my best treatment recommendation, an appointment sequence, and the financial investment. Photographs are also a helpful insert to aid in explanation for family members who were unable to attend the consultation. I think there’s value in a tangible letter taken home to revisit.  

Treatment letters are also an irreplaceable resource for my team. When a patient calls to schedule treatment previously presented, my stored letter immediately becomes a reference for scheduling appointments, including time allotments and space in-between subsequent visits. In my office, we offer a courtesy for treatment paid in full. This amount is figured in the financial investment portion of my letter so that conversations regarding immediate payment or a payment plan can easily flow. Should a case not be accepted prior to a routine recare visit, this letter serves as an excellent reminder during team huddle. It’s inefficient to page through multiple chart notes and software-driven plans with no explanation of the diagnoses which caused a need for restoration in the first place.  

In my first few years of practice, it was hard for me to accept that I needed to view this document as fluid with a potential need for multiple modifications to suit my patient’s desires and limitations. For example, financial concerns often lead to the need for phased treatment or a compromise from the ideal. I’m committed to openly discussing what may occur if no treatment is rendered or if a compromised approach is chosen. Likewise, I believe in the importance of presenting the financial component of extensive treatment myself. As the dentist and business owner, I must “own” the fee that I’ve carefully determined to reflect indirect and direct time, the skill level and support to be provided by my team, the technical excellence of my laboratory technicians, and my own knowledge. The fee that I present is steadfast, barring an unanticipated need such as root canal therapy. Should there be a need for additional chair-time or visits, it’s included in the quoted fee.  

Finally, my letters include my expectations for post-treatment maintenance. For example, if we are to complete a hybrid case in conjunction with a surgeon, I’m careful to share the importance of periodontal health and frequent maintenance visits to prevent peri-implantitis. In patients who have pre-existing medical conditions that when uncontrolled can be contradictory, I stress the importance of regular monitoring. Ultimately, I strive to empower my patients to choose and achieve oral health, Undoubtedly, oral health positively impacts overall health. My personal letters are a distinguishing trait of my practice that convey the level of care to be carried from presentation through treatment and in maintenance. Consider the value in this extra step!

I travel a lot for speaking engagements and often ride to and from the airport using Uber. As I make small talk with the drivers, inevitably they ask what I do for a living. One day, as I shared that I was a dentist, the driver said, “I’m finally straightening my teeth with those aligners.”  

I thought, “Okay, he’s either seeing a dentist or he’s doing this thing on his own.” Either assumption would’ve potentially painted me into a corner, so instead of assuming, I asked a simple, yet leading question: “Good for you. Is your dentist happy with the progress?” 

Leading questions like that help us walk a patient down the path we want. His response was, “Wait a second, this should be done with a dentist?” 

With one question, I got to the heart of the matter. From there, I responded and asked a series of simple (and again leading) questions: “Yes, seeing a dentist helps to know if you are a good candidate to move your teeth at all. How is the health of your mouth? Are your gums healthy? Do you have any cavities?” 

Now he was thinking, “Wow, not only should I be going to the dentist but there are things that could go wrong.” 

I asked him one more simple set of questions: “Would you like to know basic things that could go wrong? Or would you like to know what might really go wrong and harm you?” He, of course, wanted to know what could harm him. 

Simple, leading questions get to the point. So, when restoring a patient, I think about the simplest questions to ask to understand what the patient understands, what the patient really wants, and why. In short, I want to know what matters most to them and connect that to the dentistry I know they need. As an example, I might ask, “Do you want to replicate mother nature when we restore that tooth, or do you want to improve upon mother nature? Would you like to discuss preventing future problems that will save you time and money or just focus on today’s problems?” 

These leading, simple questions prompt a response that enables me to determine if the patient wants just a slice of pizza—say a crown, the patient wants the whole pie—an optimal smile, or the patient wants something in between. Based on that input, I know how to best have a great conversation with the patient—a conversation the patient will appreciate and through which I can earn more trust.

One of the most common ways that we temporize a patient who is having maxillary anterior implant dentistry is with an Essix retainer. Some patients will wear it 24 hours a day and others for less. Hopefully they are taking it out to rinse, brush, and floss, but the reality is they are wearing a removable device that covers all of the tooth surfaces for a lot of hours every day, and we’re increasing their risk of caries, decalcification, and gingivitis. 

In addition to discussing the normal oral hygiene to be done at home, in our practice, we typically dispense a product like Clinpro 5000 from 3M or MI Paste from GC America. These are high calcium and fluoride products that provide fluoride treatments inside the Essex retainer. 

• If a patient is sleeping in the Essix, the instructions are to brush and floss the teeth and then use a toothbrush to spread a little bit of Clinpro or MI Paste on the inside of the retainer before going to sleep. 
•  If they are not wearing the Essix during sleep, the instructions are the same but to wear the Essix for up to an hour every evening before removing it to go to sleep. 

If the patient’s caries risk is high, I prefer using 10% carbamide peroxide gel instead of Clinpro or MI Paste. This is the active ingredient we us in perio trays to help prevent gingivitis. This is also the means by which patients can whiten their teeth while wearing an Essix retainer. 

To prevent damage to the Essix, instruct patients to rinse it with cold water and, when not wearing it, to store it in the provided container.  

A while ago, I had the opportunity to repair a small bubble in an old composite restoration, and I got to thinking you might like to know how I use air abrasion to do this type of repair.

I don’t know how many times you see this, but I frequently see small holes in old composite restorations. In many cases, the margins look good. Everything looks good about the restoration except where there was an air bubble when the composite was placed and now there is a little hole on the occlusal surface. Food can get trapped and staining can occur in the hole, but the hole doesn’t descend into the tooth. And sometimes I see a little gap on the margin of an old composite with staining or early decay. In both cases, I don’t want to remove the entire restoration.

I use a lot of air abrasion in my practice, and in particular, I find it is wonderful for repairing old composite. I have the EtchMaster® from Groman. It’s a little handpiece that is super easy and convenient. It makes using air abrasion chairside something you will want to do every day.

Use 50-micron aluminum oxide air abrasion to clean out the stain, etch the old composite, and etch the tooth. If any tooth structure is to be etched, this air abrasion is a replacement for phosphoric acid. So, in one easy step, you have prepped the tooth and the composite. A plus of this technique is that local anesthetic is not needed if the hole does not extend into the tooth.

Now you can go in and use your dentin adhesive and replace your repair composite. Today, dentin adhesives contain MDP or PMMA which is the chemistry we need for the new composite to bond to the old composite. If I were to repair a composite restoration with a handpiece and a burr, I would not get the same bonded interface between the new resin and the old resin.

For both ease, patient comfort, and the best bond, I choose to treat previously polymerized resin with air abrasion and then some sort of resin that contains either MDP or PMMA.

Why Patients Want Early Detection

For more than a decade, there has been an increase in the occurrence of head and neck cancers in the United States. According to the American Cancer Society, over 53,000 people in the United States will be diagnosed with oral or oropharyngeal cancer in 2020. Worldwide, new cases of oral and oropharyngeal cancer exceed a devastating 640,000 people per year.

Head and neck cancers include those occurring in the lips, mouth, tongue, and throat. These cancers are often referred to as oral cancer or oropharyngeal (back of the mouth and throat) cancer. There are two distinct pathways by which most people develop these cancers. The one most familiar is through the use of tobacco and alcohol, and the other is through exposure to the HPV-16 virus (human papilloma virus, version 16). HPV-16 is a more recently identified etiology and the same one that is responsible for the vast majority of cervical cancers in women. In less than 7% of oral cancer cases, there is no known cause, and it is believed that these cancers are related to a genetic predisposition.

While oral and oropharyngeal cancers are still considered uncommon, The Oral Cancer Foundation reported in 2019 that approximately 132 people in the US are diagnosed each day and one person dies from oral cancer every hour of every day. This sobering statistic has not improved in many years. The most recent statistics reported by the American Cancer Society indicate there has been an ongoing rise in cases of oropharyngeal cancer linked to HPV infection in both men and women.

Oral cancers have an 80%-90% survival rate when found at early stages. Unfortunately, the majority of oral cancers are found in the late stages and this is the reason for the very high five-year death rate of 43%. Late-stage diagnosis is said to be a result of many complex conditions including a lack of public awareness and a lack of professional screenings in dental and medical offices.

Automatically Include Cancer Screening

Within your exam fee, I urge you to include a thorough oral cancer exam. Make sure your patients know the screening is automatically included in your new patient and regular exams. While performing the screening, talk about what you are doing and why. Patients are becoming more and more proactive about their health and are more than pleased to know about the inclusion of the screening. This is a health-centered benefit of your practice that will distinguish you. If your patients are aware that you are doing it, they will mention it to others and their confidence in you will grow.

Another Opportunity to Engage New Patients

My friend Linda Miles, co-founder of Oral Cancer Cause, says, “During the last few years of my teleconsults, I encouraged each dentist to develop a strong relationship with their local oncologists, radiologists and ENT specialists so that he or she would become the go-to dentist to do dental clearances for all cancer patients especially the head and neck cancer patients. In order to start radiation or chemo, all pending dental treatment must be completed. This ranges from hundreds to tens of thousands of dollars per patient to the practice. Dental Oncology is a growth path many should develop.”

It used to be a challenge for me to help patients who came in with recurrent aphthous ulcers, lichen planus or erosive lichen planus, burning mouth, burning tongue, or geographic tongue that was uncomfortable. I’d worry about the pharmaceutical reactions of prescription options such as prednisone, steroid mouth rinses, and lidocaine rinses. Now, that challenge is greatly reduced due to the success we have had treating these problems with nonprescription topical antioxidants. 

There is a group of nonprescription topical antioxidant products that I rely on weekly from PerioSciences. These products not only promote healing but also provide significant relief from soft tissue pain, xerostomia, and burning sensations in the mouth. This is PerioSciences’ AO ProVantage line of mouthwashes, gel, and toothpaste. They are without a doubt the best products I have come across in my career for oral medicine applications. They were developed by dental scientists and other researchers and contain two antioxidants from the skin of apples. The products are marketed to help with a number of things in addition to oral wound healing, for example, to treat superficial gingivitis and to maintain patients who are at advanced risk of perio inflammation.  

In my practice, I have two patients who have chronic erosive lichen planus. We discovered that the application of the AO ProVantage gel to a lesion, four or more times a day, allows the body to heal the lesion. Within three to four weeks, the lesion is gone completely. After lesions are gone, my patients stop using the gel and start using AO ProRinse three to four times a day to prevent the outbreak of another erosive lesion. If they get another lesion, they go back to using the gel. The mouth rinse has reduced the number of outbreaks for these patients, and having these products on hand, has allowed my patients to successfully manage outbreaks on their own. 

I have lots of older patients who suffer with burning mouth or burning tongue. AO ProRinse mouth rinses have worked well for them. Some of my patients have severe dry mouth in association with the burning—some with Sjogren’s syndrome, some with Lupus disease. We start them on the hydrating formula of AO ProRinse, and they rinse their mouths four to six times a day with remarkable results. It’s also been of great value to my patients going through chemotherapy to keep their mouths hydrated and comfortable.  

The PerioSciences products are nonprescription and now readily available via Amazon. Once introduced to the products and given guidance, my patients have found it easy to determine when to start using the products and how often to use them. Topical antioxidants are just one more example of industry breakthroughs I am grateful to have in my clinical toolkit and widely available to patients.
