Fillings

A dental filling is a dental material that is used to repair the look and function of a tooth that has been damaged by tooth decay.

Unlike pretty much every other part of you body, teeth cannot heal themselves when they get damaged or infected. In order to restore your tooth back to the way it should be, we have to remove the decay first. That’s what we’re doing when we use the drill when applying a filling. Yes, it does make the hole caused by the decay a little bigger temporarily, but it’s better than leaving any decay that could hurt your tooth more in the long run.

What Is A Dental Filling?

Fillings are used to fill cavities, or small holes, caused by bacterial acids that have eaten through your tooth. If left untreated, cavities can expand, carving deeper into your tooth and ultimately destroying it. Fillings halt the decay process, thereby saving your tooth and preventing more cost and discomfort in the future.

What Types of Filling Materials Are Available?

There are several types of materials that can be used for fillings. What type gets used will depend on the condition of your tooth, how you want it to look and your budget. Your dentist will always want to choose the option that optimally restores the look and function of your tooth.

The most common materials are gold, amalgam (silver), composite (plastic) resin and porcelain. Metal fillings are more common on back teeth (molars) because they don’t show when you smile. However, many patients prefer a tooth-colored, metal-free option, regardless of where in the mouth the filling will be. At our office we prefer to use new and advanced tooth fillings made of tooth-colored materials. This material is made of durable composite resin or porcelain. Tooth-colored fillings are used on the front teeth where a natural appearance is important. They can be used on the back teeth as well, depending on the location and extent of the tooth decay. Ultimately, the decision on which material to use for your dental filling will be the result of a well-informed discussion between you and the dentist.

Procedure Overview

The dental filling procedure is a very routine and relatively simple treatment.

  • We will start by giving you a local anesthetic to numb the area, if necessary. Numbing may not be necessary for very small fillings, but feel free to ask the dentist about it if you are concerned about discomfort.
  • Next, the dentist will remove the decay using a drill.
  • Once the decay is removed, the dentist may use the drill a little more to shape the tooth so the filling will fit better. The dentist may also etch the inner surfaces of the space with an acid gel to help the filling hold on better later.
  • If the material used for the filling involves resin, the dentist may use a special bright light to harden it. At the very end of the procedure, we will polish to tooth to make it smooth and shiny like the rest of your teeth.
