Hello !! My vet told me last month when I took Crash in for a checkup that he should have his teeth cleaned. Everything else looked really good. He had them cleaned when he was about 5. He's 15 now. He's been OTJ (Lantus)for 1.5 years now and doing really well with his numbers. He still eats ravenously, and does not seem to notice that he has plaque on his teeth. He does not have bad breath. If I go to the vettie bean to have him cleaned, he would need to be checked to see if he can be anesthetized, and the cleaning on top will add up to about $700. I saw an ad at my pet food store the other day about ultrasonic teeth cleaning (takes 15 minutes, no anesthesia - $105). My questions: 1) had anyone else experienced the ultrasonic cleaning? 2) do you think cleaning is a good thing with an elderly cat, or will it open up a can of health worms? 3) if I do have his teeth cleaned, is there anything to watch for health-wise after the procedure? 4) if I don't have them cleaned, can he chew a chicken neck bone or something to do it naturally or is that bad (read that in another post here) I guess I am worried about if I take the tarter off, he will have more sensitivity to cold, or maybe a cavity or something under the plaque will be exposed. I think he would let me brush his teeth if I tried. (he lets me do everything else to him - LOL) I've never anesthetized an older cat unless it was really necessary, so am thinking more about the ultrasonic than the vet. I'd really appreciate some wisdom from my FDM family - thanks so much!!! Love and miss you all!!!
