Last week I introduced you to a patient who has been struggling with dental decay (cavities), gum recession, and dental erosion (the chemical breakdown of tooth structure). I discussed how these dental problems are complex multifactorial diseases of epidemic levels affecting both children and adults.

I ended with the idea that a healthy mouth requires more than brushing, flossing, and “fillings”. With current scientific evidence and new technologies, patients and practitioners need to begin to look at these problems not just from a drilling and filling approach, but also from a medical (preventive/therapeutic) approach. If “we” continue to think the same way about dental issues, we will continue to have the same struggles and same results.

There are over 19,000 different bacteria that have been found in mouths and every person has about 1,000 different types. Not all of them cause decay, but many of them have also been found to grow on artery walls. The medical/dental systemic connection is real and we must pay more attention to it.

Dental decay is on the rise. Why the increase? Most of it has to do with dietary trends. We snack more, eat more sugar/carbs, drink more soda, have more gastric reflux, take more mouth-drying medications, etc. Dental caries (decay) is a pH specific disease. The right bacteria, plus sugar, create acid which breaks down the enamel of the teeth. Add an already acidic environment and it is even worse. In most cases it is a preventable disease. The problem is that changing our thinking and behavior, the nemesis of all that is bad, is difficult to do unless there is an awakening among us.

It is time for the dental professional to take a different approach when treating this disease. More focus needs to be shifted to prevention of decay rather just treating it. Filling teeth is treating the result of the disease but does nothing to prevent it. The dentist needs to take a more active role in assessing individual’s risk factors. In the dental world one way to do this is to use CAMBRA, which stands for Caries Management By Risk Assessment.

Based on assessing an individual’s risk factors such as quality of home care, quality of salivary flow, medication and dietary issues, a caries-preventive strategy can be established. Dentists must take some responsibility and be open to a different management of this disease. They must also be able to motivate people to change habits. The bottom line is that if you want to be decay-free, you can be.

For those at high risk, specific behavioral modifications are almost always necessary. To become aware of these often requires an assessment by your doctor. Doctors need to shift time away from treating things to be able to assess more and discuss the specific behavior modifications necessary for each individual patient. The patient needs to be receptive to hear and act on these changes.

There are also some great products currently available and others on the horizon. Everything from new toothpastes and gels with ions in them to rebuild tooth structure, sprays to neutralize pH, and probiotics are on their way. Right now you can use things like the sweetener replacement Xylitol, which by itself is cavity-fighting, but also works synergistically with fluoride. Prescription level toothpastes are also available and there is strong research for the topical application of fluoride varnish, the same stuff the kids get, for adults.

The evidence is very clear – this is a preventable disease. Next time you go to the dentist and find out you have a new cavity, stop blaming the dentist or yourself, and ask to get a specific protocol for prevention of this disease based on your specific risk factors.

Changing our behavior, habits, attitude, or any aspect of our lives can be a difficult thing to do. I am not writing as an expert on this subject as I have the same struggles as everyone else with change. However, repeated awareness of changes we want to make is one strategy to move us closer to making that change.

A good example is Mary, a patient of mine. Mary is an adult who has had issues with decay (bacterial disease that breaks down tooth structure), dental erosion (chemical breakdown of tooth structure), and gum recession (loss of the supporting structures of the teeth). When people like Mary present with these problems, we dentists present treatment to “fix” the problems. However, the reasons “WHY” these issues are occurring are just as important, if not more so, than the “fixes” we propose.

Mary drinks diet soda. In fact, Mary doesn’t just drink diet soda; she has a diet soda by her side all day long. At a recent event I saw Mary sitting and listening intently to the presentation. At her side was her diet soda. Every few minutes Mary would unscrew the diet soda cap and take a swig.

The three main dental issues Mary has: decay, erosion, and recession, have many different etiologies. One common denominator is pH, which is a scale used to describe the acidity or alkalinity of solutions or environments. The lower the pH the more acidic the solution or environment is. In order for any of the three disease processes described above to occur, the pH of the oral environment has to be acidic.

While there are many reasons the pH of the oral environment can be acidic, such as medications or disease, dietary factors play a significant role. A pH lower than 5.5 in the oral cavity puts you at risk for dental disease. Most tap water, for example, has a pH of 7. The average diet soda has a pH of 3.28. Stomach acid has a pH between 1-2. Diet soda is very acidic.

Having a diet soda with a meal on occasion is most likely not a problem. Typically, after consumption of an acidic beverage, your saliva will neutralize (make your mouth more alkaline and less acidic) within about a half hour. That is why you may have heard that you should wait at least a half hour before brushing your teeth after meals. The problem with Mary sipping the diet coke all day long is that the pH of her mouth is always acidic. This creates a very dangerous environment.

Quieter drills, new materials and technologies will not solve these problems. While etiologies such as medications that can cause dry mouth and a very acidic environment are difficult enough to manage, behavioral issues are often not discussed in enough detail, or at all, because they can be more difficult to manage.

Avoidable dental problems are the last thing a patient wants to hear about and a dentist wants to see.  In addition, we as providers need to adopt a more preventive approach to the conditions I discussed in this column. Next week I will introduce you to one of those concepts.

Do you pay much attention to those cards in a hotel room asking you to reuse your towels? Many people don’t. But one researcher, Robert Cialdini, a University of Phoenix professor and the author of Influence: The Psychology of Persuasion, found a way to get guests to cooperate. He created a card saying that most guests who stayed “in this room” reused their towels. The response beat the typical compliance rate by 33 percent.

Cialdini calls this the “Social Proof Effect,” and it is a powerful force in our increasingly connected culture. It’s not about peer pressure. It’s about peer information, and how we behave and make decisions based on the standards, expectations, and recommendations of our social groups. It’s why people share TV talk around the water cooler, and it explains the popularity of social media like Facebook and Twitter, which make it easier than ever to be plugged into what our peers are thinking and doing.

Many dental offices use social media as a way to connect with patients and bring discussions of dental issues into their cyber-world. It’s not for everyone, but there are many patients who like and benefit from it. 

The same thing goes for “Dr. Google”. It is just another way to get information. Many people use Google to help self-diagnose. Any information helps make you more informed and aids in making decisions when it comes to choices. With many people it’s reassuring—a way of validating that the choice they’re about to make has been endorsed by people like them in similar circumstances.

More and more patients are coming into the office armed with information they have collected from their own web searches. Many times it is good information, which stimulates good discussion. Other times the information brought to the table is misguided information, which can stimulate good discussion, but can also confuse people.

One potential problem is that patients often think that if something didn’t work out for someone they know, it is not right for their particular situation. For example, I have had patients come in and say, “My friend had a miserable time with a dental implant. I don’t want a dental implant.” In this situation it takes a lot more nurturing and education to convince someone that a dental implant is right for them. Sure, there are people who have problems, but there are many more people who have had positive experiences and wouldn’t want anything else.

This is where spending time one on one with patients is so important. TIME is the most precious gift a healthcare provider can give to his or her patients.  Spending time to educate people allows them to make the best decisions for themselves. The trend is to spend less time with patients. There may be many reasons for this, but one definite one is the pressure from insurance companies to control costs.  Who wins in that situation?

Whatever way you get your information, take the time to thoroughly discuss it with your healthcare provider. Bring the information you find and incorporate it into the conversation. Your healthcare provider should be YOUR biggest advocate. It should be a trusting and transparent relationship. If it doesn’t seem that way, maybe you should consider your alternatives.

I have had a few patients ask recently about the order of oral hygiene activities. Does it matter if you brush or floss first, and should this be done before or after breakfast? Based on available research, it seems opinion matters as much as scientific facts.

A spokesman for the American Dental Association and a professor of restorative dentistry at the University of California, Los Angeles, recommends flossing first. His rationale? Get the unpleasant task out of the way to avoid the temptation to not do it. “Let’s face human nature, if you’re going to skip one, which one will you skip?”

By contrast, a professor of oral health sciences at the University of Washington in Seattle, advises her patients to brush with a fluoride toothpaste, then floss. She says that way your mouth will be awash with fluoride as you are maneuvering the floss.

So, what’s my opinion? I was taught and have always maintained that flossing before brushing is better. The rationale behind this is that plaque and other debris is dislodged during the act of flossing allowing toothpaste and the mechanical action of brushing to better penetrate the different surfaces of the tooth. Does it really matter? I don’t think so.

Have you heard your dental hygienist or dentist tell you to floss to prevent cavities between your teeth? Based on research, the main reason for flossing is not for prevention of cavities. Rather, flossing’s main benefit is stimulation of tissue to reduce gum inflammation known as gingivitis. Gingivitis can lead to more advanced gum disease and things like bad breath. That is why I believe that regular use of a water pik and an electric toothbrush is most ideal.

A review of 12 randomized controlled trials found that people who brushed and flossed regularly had less gum bleeding than the brush-only camp. No surprises there. There have been no studies, that I am aware of, reporting a reduction in cavities from flossing. Of course, these are difficult studies to conduct. There are many factors that contribute to decay occurring between the teeth.

There are also different schools of thought whether to brush and floss before or after breakfast. I don’t know about you, but I cannot eat or drink anything (especially orange juice) after I brush my teeth. So, although you might expect the solution to be brushing after breakfast, there is some risk with that.

If you eat or drink something sugary or acidic—like the fruits, juices, and other breakfast foods many of us eat in the morning— the mouth is in an acidic environment for at least 30 minutes after consumption. These acids weaken tooth enamel, and brushing too soon can cause damage to the enamel. If you know you’re going to eat or drink something very acidic ahead of time, you may want to brush your teeth first.

Alternatively, you can wait 30 minutes after you eat for your saliva to neutralize the pH of your mouth. Or, re-balance your oral pH right away with an alkaline mouth rinse and then brush. In the end, it depends a little on what you eat. Take stock of what you’re eating for breakfast and judge when you should brush based on its sugar or acid content.

Everyone, well…..almost everyone, can stand some improvement with their oral hygiene. Many dental problems are completely avoidable with excellent home care, which is in your control. Ask your dentist or hygienist how to improve your home care. Strive for constant improvement.
