hi my ds is 13m and has always cut teeth in twos. His first two bottom ones came at nearly 4m nad by 6m he had 4 at the top and 4 at the bottom. He hasn't had any more teeth till recently (12m) he has cut 4 including the canine tooth on the left side 3 including the canine on the other side and some more are coming through at the bottom. Luckily (touch wood) he has been ok , he has his first ever cold at the mo which could all be to do with it but i just didn't think this was normal. He'll have all his teeth by 15m probably!When should i take him to the dentists?
