What Steps Are Involved in Filling a Tooth?

First, the dentist will inject a local anesthetic to numb the area around the tooth. Next, the dentist will use a drill, air abrasion instrument, or laser to remove the decayed area. The dentist’s comfort level, training, and investment in equipment — as well as the location and extent of the decay — will determine the choice of instrument.

Then, the dentist will probe and test the area to confirm that he or she has removed all the decay. Once the dentist clears the decay, he or she will clean the cavity of bacteria and debris to prepare the space for the filling. If the decay reaches near the root, the dentist will first place a liner made of glass ionomer, composite resin, or another material to protect the nerve. Finally, after placing the filling, the dentist will finish and polish it.

The Tooth-Colored Filling Procedure

Tooth-colored fillings require several additional steps. First, your dentist removes the decay and cleans the area, then applies the tooth-colored material in layers. Next, your dentist uses a special light to “cure” or harden each layer. Once your dentist completes the multilayering process, they shape the composite material to the desired result, trim off any excess material, and polish the final restoration.

What Types of Filling Materials Are Available?

Today, several dental filling materials are available. Teeth can be filled with gold; porcelain; silver amalgam (which consists of mercury mixed with silver, tin, zinc, and copper); or tooth-colored, plastic, and glass materials called composite resin fillings. The location and extent of the decay, cost of filling material, patients’ insurance coverage, and your dentist’s recommendation assist in determining the type of filling best for you.
