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 ] Several symptoms are commonly associated with bruxism, including aching jaw ...
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging. Advanced and excessive wear and tooth surface loss can be defined as pathological in nature ...
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.
Misophonia (or selective sound sensitivity syndrome, sound-rage) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues.These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses that are not seen in most other people.

Tongue thrusting is a type of orofacial myofunctional disorder, which is defined as habitual resting or thrusting the tongue forward and/or sideways against or between the teeth while swallowing, chewing, resting, or speaking. Abnormal swallowing patterns push the upper teeth forward and away from the upper alveolar processes and cause open bites.

Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums.
Occlusal trauma is the damage to teeth when an excessive force is acted upon them and they do not align properly. [1] When the jaws close, for instance during chewing or at rest, the relationship between the opposing teeth is referred to as occlusion. When trauma, disease or dental treatment alters occlusion by changing the biting surface of ...
