He has been having annual cleanings since I got him 2 years ago (he's 8 yrs). He's now had 3 teeth pulled. Has bad gingivitis. He won't let me brush his teeth though. He's a scaredy cat, he panics easily. He didn't have much tarter on his teeth though, so it is more likely genetic than me not taking care of his teeth, I was told. poor baby! I do the best I can with him.
