Thats so funny that you started this thread, Amy. I just got the new Foster and Smith and was looking at the dental section this morning before I came here. I am ashamed to say that I have never brushed my girls' teeth . I was looking at all the products and thinking I really need to do this. I do give them lots of dental chewies. I need to start giving them occasional brushings and I also would like to get some of that stuff that you put in their water.
