A recent report from Oral Surg and Medicine (2010) indicates that flying and scuba diving can stimulate pain in teeth with faulty dental restorations and cavities (noted 30% of the time) and root canal problems (also noted about 30% of the time). The next most common painful dental condition was from recent dental treatment (10%). Non-dental problems that are common include sinusitis and joint/muscle pain. The take home message: if you think you may have a dental problem, have it checked and possibly treated before you fly or scuba dive.
