Although accidents do happen, and no one can predict everything, there are some higher risk activities where you can take steps to protect your dental health. For example, if you’re doing contact sports, consider wearing a mouth guard during the activity to protect your teeth. Never use your teeth to bite things open, such as packaging or bottle tops – reach for the scissors instead. And avoid things like chewing popcorn kernels, ice or hard candies which have a reputation for cracking teeth.
