[sucinimad]

I had my tooth removed on Wednesday and I was freediving on Saturday. Recalling the experience, I don't think there were any problems with the tooth (or lack thereof). I did have sinus problem. Immediately after a duckdive, I would feel pressure between my eyes/middle forehead. Clearing took care of that problem. Also, 20m was the deepest dive for that day; not because the tooth presented any problems but because I was spearfishing. Of course, you should do it with cautions.
