Dd's back baby tooth in front of her permanent adult molar fell out last night and I noticed that there is a small hole in the enamel on her permanent tooth where the other tooth was touching (the area you can't see or brush) and I'm so upset. She's brushes twice a day and flosses. She's only 9 and honestly I'm absolutely gutted as her teeth seemed perfect. Dh thinks I'm being ridiculous but I feel so guilty.
