It was a silver mercury amalgam filling but it was like dry black sand =

So how can oxygen get in?

Or are all old silver amalgam fillings like that inside.

Subject: On/offgassing of tooth fillings
About 7 years ago, one of my fillings popped out after what was =
then a normal ascent (18 metre/minute). I had all my fillings checked =
then and some replced. The last 2 years I started diving a lot more, =
with a minimum of once a week, but mostly2 or 3 a week. Dives have also =
become longer and deeper and it happened again, twice and on 1 dive I =
had to suck the air out to keep the filling in place. Also, every 2 or 3 =
months one or two fillings just have to be replaced. It looks like they =
just crumble. All new fillings are being X-rayed to check for cracks and =
to make sure no air is under it, or can get under it.
=20
This made me wonder, do fillings take up nitrogen/helium? Can it =
be that they offgass so slow bubbles are formed within, which causes =
these problems? Anyone has the same problems? Maybe the teeth itself =
offgas in a way the filling comes loose?
=20
Thanks in advance for any answers

PS. Yes, I do brush my teeth.
