Types of cavities

Cavities are decayed areas of your teeth that become tiny openings or holes. The three types of cavities are shown here. Smooth surface cavities occur on the smooth sides of your teeth. Root cavities occur on the surface over the roots. Pit and fissure cavities occur on the chewing surface of your teeth. Not cleaning your teeth well, snacking a lot and sipping sugary drinks are the main causes of cavities.
