Of the 41 participants who reported dental symptoms, 42 per cent experienced barodontalgia, 24 per cent described painfrom holding the air regulator in their mouths too tightly and 22 per cent reported jaw pain. Recreational divers should consider consulting with their dentist before diving if they recently received dental care, said lead author Vinisha Ranna from the University at Buffalo (UB) in the US."Considering the air supply regulator is held in the mouth, any disorder in the oral cavity can potentially increase the divers risk of injury. An unhealthy tooth underwater would be much more obvious than on the surface..The study also found that pain was most commonly reported in the molars and that dive instructors, who require the highest level of certification, experienced dental symptomsmost frequently.Another five per cent noted that their crowns were loosened during their dive, and one person reported a broken dental filling. The research was inspired by Rannas first experience with scuba diving in 2013.She created an online survey that was distributed to 100 certified recreational divers. This frequency is likely attributed to more time spent at shallower depths where the pressure fluctuations are the greatest, said Ranna. Those who were under 18-years-old, ill or taking decongestant medication wereexcluded.
