Can you post some pictures please? Also, everyday when I bath Cooper I use the softest tooth brush I could buy and clean his mouth. It took about 2 weeks I'd say for him to get use to me doing this, but now he seems to enjoy it. And he really likes having it done to the top of his head and under his bottom jaw. I alway say "time to brush your teeth Cooper!" I'm a dork that way! Just an idea for you.
