Sealants
Dental sealants can be a very effective method of decay prevention. Coatings are placed on the chewing surface of the teeth using a special kind of resins.
It can be applied since childhood, on all teeth.
The procedure doesn't usually include trimming of the tooth and is totally painless.
Also, fluorine helps in making the teeth more resistant to decay and is used for preventative reasons every six (6) months by your dentist, up until the age of fifteen (15).
The procedure is very simple, painless and risk-free. Sterilized plastic disks are used, which have a special fluorine gel.
