I have an 8+ year old MF male. He's in mediocre health. He's been grinding his teeth off an on probably for a year now. Has been treated for ulcers on numerous occasions. Relief would be only for a few days. On the long term I put him on Pepcid AC that brought limited relief. He's had ex-rays, blood tests, and recently exploratory surgery (nothing abnormal found). Also had his teeth cleaned because they were clearly bothering him. For a week on Pepto and Amoxi he did very well, no diarrhea or tooth grinding. Now the tooth grinding is back. I've tried: Pepto Bismol Kayopectate Amoxi Carafate Pepcid AC Bland diet Ferret "Probiotics" He's had x-rays exploratory surgery On his second dose of Lupron (3 month doses) Any suggestions, his appetite is down when he is griding his teeth. Anyone have any other suggestions? [Posted in FML issue 4497]
