Cavity filling

 

A filling helps to restore a tooth damaged by decay back to its normal function and shape, and helps prevent further decay by eliminating areas where bacteria can enter the tooth. Your dentist will consider a number of factors when choosing which type of filling material is best for you; this includes the extent of the repair, whether you have allergies to certain dental materials, where in your mouth the filling is needed and the cost.

What is a Cavity Filling?

Having a cavity is no day at the park. Not only is a cavity painful, but it can also affect your daily life from eating and chewing to speaking correctly. That’s where cavity fillings come into play. A cavity filling procedure is the most common way to resolve dental decay that has penetrated the dental enamel of a tooth.
