Thanks Leslie,
I've also started to drink Green Tea, although I have it as a cold drink usually with lemon juice. I was never been a tea or coffee drinker before this started and I still don't particularly like hot drinks (apart from the occasional hot chocolate). I haven't seen any green tea extracts, but will have a look in some health food stores to see if I can find it. I have also been taking an anti-oxidant tablet morning and night (along with the usual multi-vitamins, fish oil etc.) My visits to the ENT are supposed to be every 6 weeks and I can't see that changing until my mouth stabilises.
