Dental fillings are a scientific response to the body’s inability to heal wounds in teeth. If you get a cavity, that hole stays there until filled. These fillings can be made of gold, ceramic, porcelain fused to metal, or a tooth-colored composite. The latter is the most modern choice, as most people want their fillings, and therefore the knowledge that they ever had holes in their teeth, to be invisible.
To start the filling process, our expert in dental fillings in Northridge numbs the area with a needle. After five minutes, the anesthetic kicks in and the dentist isolates the tooth from saliva—and your throat from tooth chips—by using a rubber dam. They then drill out the decay, and replace it with your chosen material.
Most fillings are done in about 15 minutes. Certain kinds may take longer, such as when the cavity is between teeth or deep inside the tooth near the nerve. In the latter case, the dentist may administer nitrous oxide to neutralize discomfort and anxiety.
If the bulk of the tooth has been destroyed by cavity, you may need root canal therapy. This is a separate process from an ordinary filling, but is just as routine.
