  • The Procedure of Cavity Filling

Cavity filling is performed when tooth decay has caused a hole in 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, the process is quite complex. Once our 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 apply a base or liner to prevent pain and sensitivity after the filling. A base is 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, the dental hygienist will mix the amalgam in a loud machine. Your dentist will use an amalgam carrier to apply the mixed amalgam to your tooth. They will push the metal down tight to prevent spaces. The dentist will then mold the amalgam into the right shape and check your bite by asking you to bite 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, our dentist will use acid on the tooth to create very small holes. It allows the resin to bond with the tooth. Our dentist will then rinse your mouth and apply priming and bonding agent with a brush. Your dentist will squirt the resin into your mouth or use an instrument to apply it. They will spread the resin evenly and cure it with light. You will need multiple layers of resin for deep cavities, which means repeating this part of the process several times.
