| Like Mal, I'm 2/3 of the way (ie 8 months) or Stage 2 through root canal treatment. This crown has to come off in August and be replaced by a lump of gold. I've dived regularly since I had it done, no dramas.
However, stage 1 involved knocking the top off the old tooth, giving it a right old clean out, dropping in a pellet of antibiotic inpregnated cottom wool (read "air space") and then whacking on a very temporary, four weeks only-cap.
I dived with that (once) and it was agonising painful.....dropping to 30m didn't help but eventually it equalised, with a sharp hiss and it was just a dull throb.
However, when I surfaced, the pressure built up and the deco stop was very very unpleasant. I was like a bear with a sore head as I sat in the boat, until relieved after 10 mins or so, by another sharp hiss. I was very tender there for a few days. Dental barotrauma is not to be trifled with.
I stayed out of the water until the longer term (12 month) cap went on; it's been fine since then, dived loadsa times, no worries.
Basically, I think it depends on the nature of your temporary crown and what's underneath it.  |
