Dental cavities, also known as caries or tooth decay, are damaged areas in the hard surface of your teeth that develop into tiny openings or holes. Cavities are caused by a combination of factors, including bacteria in your mouth, frequent snacking, sipping sugary drinks, and not cleaning your teeth well.

Bruxism is the involuntary clenching, grinding and gnashing of the teeth, with around half of the population doing this at some stage, usually as a stress response. Some people are regular and forceful tooth grinders and cause a lot of damage to their teeth, resulting in pain in the jaw. Often teeth grinding happens during sleep, but some people grind and clench their teeth while awake.
