Common Risk Factors And Causes Of Cavities

Location Of Tooth

The location of the tooth can increase an individual's risk of developing a cavity. Certain teeth are more likely to experience decay than others. The majority of individuals who develop cavities find they form in the back teeth, otherwise known as the premolars and molars. This is partially because of the shapes of these teeth. Unlike the front teeth, which are mostly flat, the molars and premolars have complicated surfaces with a lot of grooves and pits. They also tend to be larger than the front teeth and have more volume in which a cavity can form. In addition, these teeth have multiple roots rather than just a single root. It's more difficult to keep them clean than the smoother front teeth. This isn't helped by the fact they're harder to reach with a toothbrush. Switching to an electric toothbrush can sometimes help get debris out of crevices a manual brush has trouble reaching.
