There might be few underlying causes of a teeth grinding problem. Almost everyone has experienced it once in a while. Most oftentimes this happens while you are sleeping. This subconscious process of grinding teeth can be a sign of a stressful period in life. Most adults use night guard appliances to relieve stress on the jaws and reduce damage to the teeth. Night guards that may be fabricated for adults are not often recommended for children due to possible choking hazards. Although a grinding habit in children is very common, most grow out of it by the time all of their permanent teeth erupt without any harmful effects on their oral health.
