DS is 6 and has generally good teeth. He went to the dentist a few months ago and they were all ok. He brushes well with an electric toothbrush. One of his top front teeth (milk teeth) has gone brown. I've read a bit on the internet and it appears it might be that a knock has damaged the blood supply and it should right itself with time.
I just wondered if anyone else had had the same thing and could tell me how long it lasted and whether the new tooth was damaged.
Thanks
