HI, I think cavitations are very common and occur in most people when the tooth has been removed. But I think it depends whether the area has a lot of hidden bacteria and whether the immune system is strong enough to hold the bacteria in the one place, or whether the immune system has taken too many knocks and can no longer hold the bacteria back and it can then spread.

So sometimes a person might have not much sign of cavitation, yet have big problems. I had no facial pain at all, no external signals, just the internal toxicity.

Some people do get external symptoms of pain, swelling, outer infection etc. But at least in some respects it's obvious and can be easily spotted. Not sure about an abscess, I thought that was from an infected tooth. But could well be more a cavitation also. It should not keep recurring and a dentist should be taking care of the underlning problem with your friend. That's unreal!

If you feel that there is a problem, you could get them opened upa nd cleaned out by a dentist or oral surgeon at some point, who is experienced and will do it properly and thoroughly and not allow for recurrence. Some can recur and have to be redone. I wish I had never had my wisdom teeth removed.

But you could just concentrate for now on reducing mercury and see how you go with that before considering cavitations. I think it's overwhelming to try and grapple with all these issues that these dentists have created. They have a lot to answer for.

P.S. cavitations do not always show up on xrays, they are hard to detect. Some do, but can be vague. So not easy to diagnose.
