I have had problems with my WT but have had them removed - i user pain killers and bonjella but now DH is having problems with his WT and bonjella does not work for him and he does not like pain killers so he is using SM33 (available at the chemist) - it tastes nasty but it numbs his gum so he is able to eat and talk when its too sore.
hope it works out for you
