[Angel Sweet Pea]

Hi, I need some help. I have been working with my Rescued Yorkie every day but slowly getting her use to me putting my finger on her teeth and I finally have gotten to the point that she will let me put my finger in her mouth. It took a long time because she is an adult dog and is not use to having anyone do her teeth. I have been rubbing the outside of her teeth with gauze wrapped around my finger and a little dot of tropiclean gel. But this is not doing a great job. I got a baby toothbrush and puppy tooth brush and she will not let me get this in her mouth. Her mouth is so tiny. It's about the size of the baby smallest tooth brush... The finger brush that came with the puppy kit from nylabone is too big to get in her mouth... I look at it and say to myself geez... I WOULD LIKE TO KNOW WHAT OTHERS ARE DOING WHO HAVE 4-5LB DOGS WITH SMALL MOUTHS... IS THERE A SPECIAL PLACE TO GO TO GET A TOY BREED FINGER BRUSH?? or IS THERE ANY OTHER SOLUTION OTHER THEN THE TOOTH BRUSH?? I want to do what is best for her and keep her as healthy as I can now that she is with me. I KNOW I WOULD BE SUCCESSFUL IF I FOUND ONE BECAUSE I CAN GET MY FINGER IN HER MOUTH. I was going to get an enzymatic tooth paste from CET but reviews talk about a silver packaging coming off into the tooth paste. Any other suggestions? THANKS SO MUCH
