Brushed my 8 year old teeth tonight and he complained that one of his teeth towards the back was sore. Looked at his mouth in the light and to my horror noticed that the whole side of the tooth looks decayed. I thought to start with that it was food that had got caught but after calling DH to inspect we are convinced its a large hole. Feeling so terrible especially because we have missed a dentist appointment as he was very poorly and in hospital. It must be over a year since he last went. We clean his teeth twice a day, he doesn't eat sweets or drink squash etc. He is a terrible teeth grinder at night and the dentist has acknowledged that his teeth are showing signs of wear because of it. Should I just wait until Monday to try and see a dentist or should I try and get an emergency dentist tomorrow? Will they need to remove it ? If so can they do it without a general?
