hi ... i seem to have developed dark spots on my tongue ... i can brush them off .. and was wondering has this happened to any one? i use listerine strips i wondered if it was the blue off them ?? .. but i cant see that some how cos its more a browny colour.. like i say they brush off but then reappear in another or same place day after.... or is it something more sinister ... i am a bit worried that it may be the diet affecting my health ... had no problems in this area before nice pink healthy tongue.. well unless i had had a few red wines! i hope not cos i feel fine so far .. any advice would be gratefully recieved .... :sign0009:
