Fluoride Releasing Dental Fillings

Posted in Fillings

Dental fillings are the first line of defense in strengthening teeth that have already been compromised by decay. Fillings replace infected tooth structure and seal off the drilled area with the aim to prevent decay from recurring. Many dental offices offer fluoride-releasing fillings as an added measure of protection for those at high risk for cavities.

Different Kinds of Fillings

Dental restorations are broadly categorized into two different classes: metal fillings and tooth-colored fillings. The metal (amalgam) restorations have long been used because they would last a long time and created a mechanical lock with the tooth. The more modern composite resin fillings, on the other hand, create a chemical bond with the tooth. This means that less tooth structure has to be removed to make them fit securely.

But there is another kind of tooth-colored filling. Glass ionomer restorations and cements ionically bond to teeth and contain fluoride, which is slowly released in small amounts over time.

Benefits of Fluoride Releasing Fillings

Glass ionomer ingredients can be used in the process of preparing the tooth for a filling. A layer of this material has shown to reinforce the tooth structure all around the margins of the filling. This makes the tooth less likely to succumb to decay at the margin where the filling meets the tooth.

Fluoride-releasing fillings can play a major role in the health of someone at high risk for tooth decay. A diligent oral hygiene routine, regular cleanings, plenty of fluoride, and strong cavity-resistant fillings will all help you to ward off tooth decay. The next time you need a filling, ask your dentist about what materials are best suited to your needs.
