My DS has 9 teeth....and he loves to bite! We use either a silicone rubber thing that goes over our index to brush his teeth or the thing that resembles a tooth brush that he holds. When we use the silicone thing, he'll allow us to brush real quick before biting and then he'll jam his mouth shut. With the other, he'll do it real quick himself to. I feel like its not done properly. Should i bring him see a dentist? Do dentist see kids so young? How do you brush your kids teeth?
