My 19 month old son is very difficult. It is always a fight to get him to brush his teeth. We have always fought him from the beginning about this but he does get his teeth brushed. A couple of days ago, he was smiling very big and I saw some brown spots at the top of his front teeth close to the gum line. I had to hold him down to take a better look and it appears to be holes. I am completely heart wrenched because I know this is my fault. What type of treatments are available for toddlers with this problem?
