Quick Reference

Dental pain induced by a change in barometric pressure in an otherwise asymptomatic tooth. It may be experienced by pilots and mountain climbers during changes in barometric pressure. Possible causes of barodontalgia include caries, defective restorations, pulpitis, and pulp necrosis. Barodontalgia may also be due to referred pain from acute or chronic inflammation of one or more of the paranasal sinuses (barosinusitis) or acute or chronic traumatic inflammation in the middle ear space ( barotitis-media). Fracture of restorations ( dental barotrauma) has been reported to occur at high altitude, of which predisposing factors may include a leaking restoration or latent secondary caries underneath an existing restoration.
