A tooth cavity is a hole in the tooth that emerges from tooth decay. Dental hygiene can help prevent cavities. However, the reality is that anyone can get a cavity. Acids in foods and drinks can erode the enamel (tooth’s hard outer layer), creating a tooth cavity.

You will likely become aware of your cavities when you visit your dentist for your regular exam and cleaning. Once you come into a dentist office to get your cavity filled, the dentist will start by applying a local anesthetic, then using an abrasive tool to remove the portion of the tooth that has decayed and fill it with a wide variety of materials, such as:

• Amalgam Fillings: Amalgam fillings are strong and are ideal for filling cavities in the back of the mouth.
• Composite Fillings: A combination of glass or quartz filler and can be made to match the color of your tooth. 
• Metals: Gold or silver are the most common metals used for cavity fillings.
• Ceramic: A ceramic cavity filling is tooth-colored, and it is less likely to stain over time than a composite cavity filling. 
• Glass Ionomer: A blend of acrylic and glass used to create a cavity filling that releases fluoride to help protect teeth.
