My daughter is 19 months old and her top teeth seem to be disintegrating! They are extremely chipped and it's getting worse. I brush them everyday but it is traumatising (for both of us). We've been to the dentist and and he said to rub toothpaste on her teeth but she will not let me in her mouth, I have to pin her down to brush them and even then it's a struggle. It's awful and I absolutely hate doing it but I have to brush them, it's not something I can just leave. I've tried different toothpastes, different brushes nothing helps. I think they hurt too as she only seems to use her back teeth for eating. I feel terrible for her. She doesn't have anything sweet and she only drinks water. Her older sisters teeth are lovely, no issues at all. Any ideas on why this is or what I can do to help would be greatly appreciated
