Hi philomena
I believe my OLP started when I had several crowns put in, menaing that lots of mercury amalgam fillings were removed as the teeth were filed down. It eventually calmed down.
I later had all the remaining mercury fillings replaced, and the OLP flared up again, but again calmed down after a few weeks.
I had 3 teeth out 6 months ago, to be replaced with implants, and the OLP flared up again!
I am advised that they don't want to do the implants until the gum is healthy, and the OLP has calmed down again. My (Swiss) surgeon says OLP is never "cured", just controlled, or calms down for a while, till something triggers it again.
He also said, comfortingly, that in 95% of his patients it does not lead to major problems, and is pain-free (like mine), so I guess this board has postings from the other 5%.
I have had one titanium implant for the last 3 years, when an old crown and post split, and there does not seem to have been any problem with that.
My UK dentist was sympathetic to the idea that mercury amalgam fillings can cause problems, in those who are susceptible to it, not the whole population. She once removed all MA fillings for a patient who had suffered from ME for 4 or 5 years, and was at her wits end, and even two weeks later, the patient called her and said she felt better than she had in years, and she was quickly back to normal again.
Canada has been ahead of the US - in 1996 it recommended banning the use of MA fillings for children and pregnant women, and has been campaigning for a worldwide ban.
