Dental Fillings in New Westminster

If you get a cavity in one of your teeth, your dentist will recommend fillings. Fillings are used to prevent bacteria from entering the tooth and causing infection. It is important to treat cavities as and when they arise, as dental decay can spread and affect a greater portion of the tooth. If an infection infiltrates the pulp, your dentist will have to perform a more intensive procedure called a root canal.

Composite Fillings

Amalgam fillings made of metal were commonly used to fill cavities. However, these days most people prefer composite fillings because they have a more natural appearance, and the colour can be customized to match your other teeth. The composite filling material is made from a plastic resin mixed with a powdered glass filler. This material is also used for other dental restorations, including veneers, inlays, and dental crowns.

What Is the Filling Procedure?

Your dentist will numb the area around the tooth with a local anesthetic. They will then remove the decayed part of the tooth by using a laser or a drill. At this stage, they will clean the cavity to remove any accumulated bacteria and seal the cavity with a filling. If the cavity has developed close to the root area, your dentist may also insert a liner to protect the nerve before sealing the cavity.
