Hi Tina,
May. Ot be much help, but question, have your mouth ulcers etc gone altogether yet? Could that be a cause? Colin was given muguard to do mouthwashes and the good old fashioned salt and water mouthwash a few times a day? Wonder if that might help. Also do you have a really dry mouth as that might also be a cause, I remebr the hospital giving Colin some cream to sort of rinse around his mouth to make it have more saliva?
Just me guessing but I hope it helps 🙂
