I have taken him to the dentist who said he has no dental problems, I took him to the GP who was spectacularly unhelpful and just said it was one of those things but really it is utterly foul. Soon he is going to start getting comments from other children and he is quite a sensitive boy, I don't want this to destroy his confidence (he is 8yrs old)
Please does anyone have any suggestions as to what I can do to help him? I am really worried for him but no-one seems to want be able to help

Thanks
