  • The Procedure of Cavity Filling

Cavity filling is performed when a tooth decay has caused a hole on a tooth surface. It will help repair the tooth to prevent tooth decay. Pain and then an abscess will occur if cavity filling is not performed. You most likely understand the basics of receiving a filling: your dentist numbs your mouth, removes the decay, and fills the hole. If it seems like a lot more is going on, that’s because the process is actually quite complex. Once your dentist has cleaned away the decay, the remaining part of the procedure depends on the type of material for your cavity filling in Newmarket.

The Procedure for Amalgam Fillings

If any part of the internal tooth is exposed, your dentist will begin by applying a base or liner to prevent pain and sensitivity after the filling is complete. A base is for when decay is very close to the nerve, whereas a liner is for the passageway reaching the nerve.

Once the base or liner is dry, you will hear the dental hygienist mixing the amalgam in a loud machine. Your dentist will apply the mixed amalgam to your tooth using an amalgam carrier. He or she will push the metal down tight to prevent spaces. The dentist will then mold the amalgam into the right shape and finally check your bite by asking you to bite down on carbon paper.

The Procedure for Composite Fillings

Another common type of cavity filling is composite resin. There are a few differences in the process.

First, your dentist will use acid on the tooth to create very small holes. This allows the resin to bond with the tooth. Your dentist will then rinse your mouth and apply priming and bonding agent with a brush. To apply the resin, your dentist will either squirt it into your mouth or use an instrument. He or she will spread the resin evenly and cure it with a light. For deep cavities, you will need multiple layers of resin, which means repeating this part of the process several times.
