You’re seeing commercials on television that talk about a product’s ability to reverse cavities. So can these products really work? And what works best?
​
First a little bit of background. A tooth actually develops a “cavity” when bacteria eats through the outer enamel layer of the tooth and gets into the softer dentin layer that lies below the enamel.

We’ve known for several years that you can use fluoride to reverse a pre-cavity, but it requires repeated regular applications of fluoride to accomplish this reversal. Two of the best ways to accomplish this are with application of fluoride varnishes or the daily use of custom fluoride trays at home.
​
Fluoride varnish is a highly concentrated temporary dose of fluoride. The varnish holds fluoride close to the tooth surface for a longer period of time than other concentrated fluoride products. The varnish, usually tooth colored, is applied by a dental professional. When the varnish is used repeatedly, it can actually reverse the pre-cavity by remineralizing the tooth.

To use the custom fluoride trays, we recommend the following regimen:

1. Brush and floss sometime in the evening, close enough to bedtime that you won’t be eating again.
2. Apply 6-8 drops of prescription strength fluoride gel (5000 ppm fluoride), such as Prevident or Fluoridex, to both the upper and lower trays.
3. Place the trays over your teeth, seating them completely, and wear the trays for 5-10 minutes. The longer the dose, the more effective the product, and the better the results.
4. Remove the trays, rinse your mouth out with water, spit, and go to bed without eating. If you live in an area that does not have fluoride in the drinking water, you do not need to wash the excess fluoride out of your mouth. In this case, spit out the excess fluoride and go to bed without eating anything. This leaves a thin layer of fluoride on the teeth all night.
5. After removing the trays, wash them out with water and place them in your case to let them drain out and dry before the next use.

​There are some newer products that are even more effective at reversing pre-cavities. A product called MI Paste can reverse the pre-cavities and often reverse the opaque white spot caused by the pre-cavity. MI Paste works by releasing calcium and phosphate ions into your tooth enamel. It can be brushed on, or can be worn in the custom fluoride trays already mentioned.

Of the three causes for tooth loss, the one that surprises most people is excessive bite forces.  The American Dental Association says that approximately one in three adults grind their teeth when they sleep. 

The condition, called bruxism, places unhealthy forces on teeth that can cause flattened or worn-down teeth, chipped areas at the gumline, loose teeth, and damages to your jaw joint.
 
The most frequent causes of bruxism are stress and bite discrepancies.  In a healthy bite, the teeth come together in harmony to protect the teeth and your jaw joint.  That harmony can be lost when you have periodontal disease, tooth crowding, or missing teeth that have allowed the remaining teeth to shift or tilt.  Even if your bite is perfect, stress can cause you to grind your teeth.  Of people that are restless sleepers, 95% grind their teeth.  The same brain activity that causes you to toss and turn also causes the bruxing.

Let’s look at an example of bruxism.  In the first photo, the teeth have already been shortened by at least one-fourth of their length.  Often patients with problems even this severe are not aware that they are bruxing, and many will even deny it when shown the severity of the problem.   And if your spouse sleeps more soundly that you, he or she may also be unaware of the problem.

As a dentist, I hear patients make comments like “I sleep with my mouth open, so that can’t be happening.”  Bruxing doesn’t occur constantly when you sleep, but if it’s happening, it still will cause damage.

Below are some questions that may tell you a problem is present:

• Have you noticed worn teeth that seem to be getting gradually worse?
• Do your teeth feel like they have more than one place that feels like a “home base” to touch when all of the teeth come together?
• Do your jaws feel tired at the end of the day or when you awaken in the morning?
• Do you sometimes awaken with headaches?
• Do you avoid eating foods like bagels because it’s not comfortable?

​One treatment for bruxism is the use of a bite guard.  A bite guard is a plastic appliance that fits over your teeth and protects them from damaged that’s caused by grinding.  The kind of bite guards sold at the pharmacy can actually make things worse.  Custom nightguards can be made that are extremely comfortable, and the newest designs, like the one shown here, actually have a relaxing effect on the muscles.

​If the arrangement of your teeth lacks harmony, there may be advantages to changing how your bite comes together.  Orthodontic treatment (“braces”) can make dramatic changes, or your dentist can use a process called equilibration to reshape the biting surfaces of your teeth to improve the way they come together.
