Preventive and Diagnostic
Pre-formed, ready-to-wear mouth guards can be purchased inexpensively at many sporting stores, but they do not always fit well. They can be uncomfortable and interfere with talking and even breathing.
Sporting goods stores also offer semi-custom mouth guards, in which the plastic is heated and then the athlete bites on it while still warm to provide some level of custom fit.
Your dentist can make a custom mouth guard by taking an impression of your teeth and then creating a device fitted to your mouth for the highest level of both comfort and protection. A custom fitted mouthguard can be particularly important for athletes who wear braces.
Be sure to bring your mouthguard to your dental appointments so your doctor can be sure it still fits you well.
Even small movement of the cracked tooth pieces during chewing can cause irritation to the tooth’s pulp, which causes pain. Similarly, when the bite is released, the crack can close quickly, causing sharp pain. Over time, the tooth pulp will become damaged. As this happens, the tooth will hurt more consistently. Cracks can sometimes lead to infections in the pulp tissue and spread to the surrounding gum and bone.
