As much as 33% of people brux (aka grind or clench) their teeth. If a person has lost bone support around their teeth, it is traumatic to grind or clench. The purpose of a night guard is to reduce the negative effects of bruxism. These negative effects can include mobile teeth, drifting teeth, recession or clefting of the gum tissue, wear of teeth, “v” shaped erosions in the root surfaces, increased bone loss, muscle soreness or stiffness, joint clicking and joint soreness or stiffness.
Mouth guards are required in only four school-based sports: football, ice hockey, lacrosse, and field hockey. Yet basketball and baseball are associated with the largest number of dental injuries. Other sports for which the American Dental Association (ADA) recommends wearing a mouthguard include bicycling, soccer, skateboarding, wrestling and volleyball. Do mouth guards work? The ADA estimates that athletes who don't wear mouth guards are 60 times more likely to suffer dental injury than those who do.
