Film on teeth is a dental procedure that involves the application of a thin, protective coating to the surface of the teeth. This coating is made of a special type of plastic film and is designed to protect the teeth from PLAQUE, bacteria, and other harmful substances. The film also helps to reduce staining and discoloration of the teeth, making them look brighter and healthier. The procedure is relatively quick and painless, and can be done in a single visit to the dentist.
