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.
In your mouth, these demineralized areas, or “pre-cavities” look like opaque white or brown spots, as shown in the picture below.
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.
Custom fluoride trays look similar to bleaching trays or whitening trays, but are specifically designed to cover your teeth completely at the gum line. They are fabricated to fit directly over your upper and lower teeth, and are used to hold a few drops of concentrated fluoride on the teeth. For about the cost of having one cavity filled, the custom fluoride trays provide you with a way of doing a professional strength fluoride treatment every day.
To use the custom fluoride trays, we recommend the following regimen:
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.
There are many effective tools for fighting cavities before they start. Give us a call today so that we can help give you the smile you want.
