Barodontalgia, commonly known as tooth squeeze, is a pain in a tooth caused by a change in ambient pressure. The pain usually ceases at ground level. Dental barotrauma is a condition in which such changes in barometric pressure changes cause damage to the dentition. Description
The most common victims are underwater divers because in deep dives pressures can increase by several atmospheres, and military pilots because of rapid changes. In pilots, barodontalgia may be severe enough to cause premature cessation of flights.Most of the available data regarding barodontalgia is derived from high-altitude chamber simulations rather than actual flights. Barodontalgia prevalence was between 0.7% and 2% in the 1940s, and 0.3% in the 1960s.Similarly, cases of barodontalgia were reported in 0.3% of high altitude-chamber simulations in the Luftwaffe.The rate of barodontalgia was about 1 case per 100 flight-years in the Israeli Air Force. During World War II, about one-tenth of American aircrews had one or more episodes of barodontalgia. In a recent study, 8.2% of 331 Israeli Air Force aircrews, reported at least one episode of barodontalgia.In addition, a large epidemiologic study suggested that changes in barometric pressure were the reason for the initiation and/or exacerbation of various oral pains observed in dental emergency departments.Barodontalgia is a symptom of dental disease, for example inflammatory cyst in the mandible. Indeed, most of the common oral pathologies have been reported as possible sources of barodontalgia: dental caries, defective tooth restoration, pulpitis, pulp necrosis, apical periodontitis, periodontal pockets, impacted teeth, and mucous retention cysts.
Identifying the pain during a pressure change is a diagnostic indicator for the clinician. Treatment involves removing the void space by carefully replacing the offending restoration, repeating the endodontic treatment or removing the tooth. See also
