Hi sosick, thanks for the advice. Coincidentally I've started brushing with baking soda and rock salt nightly and will add hydrogen perioxide to the mix. Apparently an excellent gum remedy is 3 parts baking soda, 1 part salt, shaken up and mixed and then pour a bit into your hand mix with hydrogen peroxide and brush.

Yeah, the tooth that this is happening too has had the filling material replaced more than the other ones in my mouth, so it too is a victim of change I think (trauma). I understimated this and didn't realise it would happen to me and it seems it has.

It's twingeing permanently now, so obviously it's a cry for help. I'll not do anything for a wee while and see if things settle. If not, I may opt for the extraction. I know that there are some biologic dentists who are now doing root canals because they say there is an excellent new way of doing them without the old style risks.....but I'm not sure about it.

I'm just concerned that getting a tooth removed there might make me look different or something. I know when I had my wisdom teeth removed, my face altered even after that. I should have left them alone too!

Thanks for you advice.
