If you have one or more missing teeth, a dental bridge can fill the gap with one or more artificial (false) teeth. A bridge is typically made of crowns on either side of the missing tooth or teeth supporting the pontic (false tooth) and is cemented in place. The most common causes of missing teeth are tooth decay, gum disease and injury. Or you may have been born with missing teeth due to a congenital condition. To get a dental bridge, you need healthy teeth on either side of the missing ones.
Cavities are permanently damaged areas in the hard surface of your teeth that develop into tiny holes. Cavities, also called tooth decay, are caused by bacteria in your mouth, frequent snacking, sipping sugary drinks, and not cleaning your teeth well.
