A key element of the DAN Mission is educating the diving public and the medical profession on the appropriate care for divers injured in dive accidents. This education takes on many forms, disseminating information on topics related to dive safety through articles, reports, seminars, lectures and training programs.

Can i do scuba with crowns and veneers?

[@DrFJCronje]

Thank you for your question! Dental implants usually do not entrap bubbles. The highest risk for dental pain or tooth implosion or explosion is poor fillings. Crowns and veneers are usually not a problem. The critical issue is entrapped gas or, more specifically, a type of one-way collection of gas under a lousy filling. It is undoubtedly advisable to wait a few days after dental surgery (until completely pain-free) or a filling (at least 48 hours after or 24 hours after the analgesic/local anaesthetic has worn off) and resuming diving. Fresh fillings (especially amalgam ones (which are becoming less common) can conduct cold temperatures from the water or inhaled cold gas/air) and cause discomfort, but a well-performed filling is typically not a problem. If there are doubts, a routine dental X-ray (panorex) can identify trapped bubbles under poor or decayed fillings. Thanks for your comments that allowed us to post this expansion on the topic.
