Mouthguard worn in handball, a contact sport An example of a mouthguard used in the treatment of bruxism. A mouthguard is a protective device for the mouth that covers the teeth and gums to prevent and reduce injury to the teeth, arches, lips and gums.
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [2]
In order to treat mobility, teeth can be joined or splinted together in order to distribute biting forces between several teeth rather than the individual mobile tooth. A splint differs from a mouthguard as a mouth guard covers both gums and teeth to prevent injury and absorb shock from falls or blows. [32]
In contact sports, risk of mouth trauma and tooth injury is reduced by wearing mouthguards and helmets with a facemask (e.g., a football helmet, a goalie mask). Nightguards may also be implemented in the case of teeth grinding (bruxism) during sleep. These guards function in limiting the wear and force applied to the teeth.
Whereas teeth rarely come into contact during normal chewing, grinding of teeth may occur 1-4 hours in a 24-hour period, most often during sleep. The amount of pressure placed on teeth during functional habits is 140–550 kilopascals (20–80 psi), but the pressure can range from 2–20.7 megapascals (290–3,000 psi) during parafunctional habits.
Smith’s dentist said it was likely from trauma: grinding, biting her nails, or doing something with her smile that’s softly hitting the veneer over and over. “I was told that can eventually ...
The Nociceptive trigeminal inhibition tension suppression system (abbreviated to NTI-TSS, or NTI-tension suppression system), [1] is a type of occlusal splint that is claimed to prevent headache and migraine by reducing sleep bruxism (night-time tooth clenching and grinding).
The focus of improvement in appliance design is in reducing bulk, permitting free jaw movement (permitting yawning, speaking, and drinking), and allowing the user to breathe through the mouth (early "welded gum shield"-type devices prevented oral breathing). [citation needed]
