“A study published in the British Journal of Sports Medicine claims that many standard design scuba mouthpieces are potentially hazardous.
The Study done by the Newcastle and Dundee Dental Schools points to the fact that little has changed in forty years of design and that the use of these mouthpieces could result in vertigo and disorientation.
