What is best to do when a tooth decay occurs?
I noticed that my cousin (age 15) has some of her teeth decayed, i have researched it up, and found out that she has root cavities.
What the best possible method for her to get rid of tooth decay?
Most dentists would advise fillings if there is true decay . If it is on the roots, sometimes ozone therapy can be done. Ozone is available pretty much everywhere but the US. It sterilizes the root and hardens the tooth stronger than the original tooth. (better than a filling). Some dentists in the US offer ozone, most do not.
