If there are any dentists or other parents with similar experiences please comment.
Over the christmas holidays my 3 year old daughter got a door in her face (another child opened the door and slammed it behind her just as my daughter was going through it). I was mostly concerned at the time about a big lump on her forehead and a crack to the skin where the impact was so we applied lots of ice and keept a close eye on her until the swelling went down. She seemed fine and her bump healed well. At the time she seemed mostly bothered by the forehead injury but did indicate the whole of her left side of head and face as painful, including her mouth. Two days ago the left front tooth started becoming discoloured, noticably different from her right tooth.
I am wondering firstly if this means her nerve has died and that her tooth will continue to become more and more discoloured and secondly if there is anything I can do to stop this from happening further. Should I take her to the dentist? If this milktooth becomes discoloured will her subsequent tooth most likely be fine? Or has the nerve died entierly?
I would really appreciate advice as I have never seen such a thing before.
