Has anyone every heard of a child on the spectrum can have their first teeth come in with very bad tooth decay? Mostly their baby teeth. This was a discussion I had with a friend who has a child on the spectrum and they have very bad enamel problems and decay, even though they as parents have and are taking very good care of their child's oral health. I know I had very bad tooth positioning but I've never heard of this. They said their doctor told them this can be common. Any thoughts?
