Bad Filling and Deep Diving

Post Number:#1  Postby SeaDemon » Tue Apr 03, 2007 3:35 am

Doc, I was in the toilet planning my deep dive and so on when I remembered that before a high altitude jump, we had to have our dental fillings re-done (yes..painful) before we could go for a chamber ride to simulate hypobaric conditions of 6000 meters.

Say if a diver has bad fillings and somehow air has gotten into a bad filling while diving at..say, 60msw.,would it expand to cause severe pain as it would in a depressurized aircraft cabin at 6000m or any other hypobaric conditions?

Had a friend that the problem during a dive back in the 80's. The filling split his tooth during the decend -the air the broke his jaw during the ascend... -He was luckily in "hard-hat" so besides the pain and blood everywhere he was ok! [smiley=shocked.gif] [smiley=shocked.gif]

It doesn't seem to be that much of a problem with the newer type of fillings these days but can still hurt!

Yeah...many people take their dental health for granted. Stuff like this do happen once in a while and the victim's always in for a rude shock. ::)

Would it expand?? Definitely!! As long as you ascend from a high-pressure environment to a lower-pressure environment, the air in the filling will definitely expand...regardless whether you're from 60msw going to the surface, or from flying from 0m sea level up to 6000m high, the total barometric pressure reduces, hence the volume of air expands. That's according to the Boyle's Law (still remember that law, SD??)

Hope that explains your queries...

Yeah, I remember Boyle's Law, Doc. Was just wondering what kind of effect would it have in diving..but I guess Santadive's description of his friend's problem explains it too  ;D :o
