A chipped tooth can happen for a variety of reasons including biting something hard, hitting your mouth, or grinding your teeth. Not only is having a chipped tooth aesthetically displeasing to you smile, it can lead to other problems. Sharp edges can cut your inner mouth, while deep chips can impact tooth roots (possibly leading to infections or toothaches), as well as tooth decay (which can cause sensitivity and bad breath). To avoid needing a root canal or extraction, it’s important to have a dentist examine and fix a chipped tooth before the problem gets any worse.
