Fillings do just what the name implies — a material is placed to fill a hole in your tooth, i.e., a cavity, caused by decay. This prevents the decay from spreading further into your tooth and, if untreated, continue on to the nerve tissue located in the center of the tooth where the nerve is located. Should that happen, you could possibly require root canal treatment.
There are a variety of materials used to fill teeth these days, but the process of filling a tooth is similar regardless. The first step is a clinical exam of the tooth, with x-rays, to determine the extent of the decay. Then the decayed area of the tooth is removed, usually with a handheld instrument such as a dental drill. Of course, your tooth will be anesthetized first, so you won't feel any discomfort. After removing the decay, the remaining tooth structure is disinfected and a filling is placed. Dr. Corella offers both silver (amalgam) and tooth colored (composite) fillings.
