The lead of the pilot study, Vinisha Ranna, who is also a keen scuba diver, became interested in the problem after she experienced it herself. In her case it manifested as a squeezing sensation in the teeth, known as barodontalgia

In order to see just how common and severe this problem is, she distributed a questionnaire through social media platforms dedicated to scuba diving and collected data from 100 scuba diving enthusiasts. A substantial number replied they experienced symptoms that range from tooth, jaw and gum pain to loosened crowns and broken dental fillings.

Due to the constant jaw clenching and fluctuations in the atmospheric pressure underwater, divers may experience symptoms ranging from tooth, jaw and gum pain to loosened crowns and broken dental fillings. Recreational divers should consult their dentist before diving if they recently received dental care, said lead author Vinisha Ranna, BDS, a student in the UB School of Dental Medicine.

When Shearwater first introduced their new Perdix dive computer in December 2015, I was pretty excited.
