I will ask about the cleaning. I think the infection was the first concern. His teeth are very yellow in the back and the gums were red. I cannot tell if there was build-up of plaque. Perhaps when I go back, he will look at them again and try to remove some of the plaque.

I'll remove the back teeth before I let him get sick and die, but if a cleaning every few years solves the problem, that would work also.

He said it depends upon the cat. Spunky, who has numerous problems, has excellent teeth. Now was for his four left feet.....
