Patients who suffer from tooth grinding, or bruxism, may contend with frequent headaches as well as jaw soreness and stiffness. While bruxism patients may think that these uncomfortable and often painful symptoms are a fact of life, many are not aware that teeth grinding can lead to more severe concerns like temporomandibular joint pain and cracked teeth. Grinding is unlikely to permanently damage teeth in the short term, but if the friction continues over weeks or years, tooth enamel and even the teeth themselves can be worn down.
Patients who are at higher risk for damaging teeth as a result of bruxism may be prescribed a thicker guard than those who have a milder form of the condition. These mouthguards can be worn at any time of day, but they are most often worn at nighttime when grinding cannot be consciously controlled.
