I know some of you do a great job at brushing your baby's teeth but for Maximus, forget about it. He will fight with all he's got when I try. He is 2 1/2/ years old and recently I noticed that he has some stains. When I asked the vet about getiting teeth cleaned professionally, she said it wasn't necessary. What do you guys do? I don't want his teeth falling out but I'm not too crazy about him putting under.
