A dental filling is a way to restore a tooth back to its normal function and shape. A filling is done by removing the decay areas of the tooth and cleaning the affected area. The cleaned out cavity will be filled with a filling material. By closing off spaces where bacteria can enter, a filling also helps prevent further decay.
How Do I Know if I Need a Filling?
Only your dentist can detect whether or not you have a cavity that needs to be filled. During a checkup, your dentist will use a small mirror to examine the surfaces of each tooth.
Anything that looks abnormal will then be closely checked with special instruments. Your dentist may also x-ray your entire mouth or a section of it. The type of treatment your dentist chooses will depend on the extent of damage caused by decay.
