Cavities, also known as dental caries, are a common problem affecting people of all ages. They are caused by the erosion of tooth enamel, the hard outer layer of the tooth, due to the action of bacteria in the mouth. If left untreated, cavities can lead to pain, infection, and even tooth loss.
Dentists are qualified professionals who are trained to diagnose and treat cavities. The process of filling a cavity typically involves removing the decayed portion of the tooth, cleaning the area, and filling the cavity with a suitable material, such as amalgam, composite resin, or glass ionomer cement. This helps to restore the tooth's function and prevent further decay.
