Maybe, maybe not. You don't need to rush her to the dentist unless they are hurting her. The nerve in these teeth could begin to die b/c of the trauma to them. If this happens, these teeth will begin to darken in appearance and then they can possibly begin to get infected and hurt, but this doen't usually happen. There is nothing your dentist can do other than watch the teeth and remove them if they hurt or perform a baby root canal. Wow, the people in here are very judgemental. Just to explain, THIS IS VERY COMMON! We see it almost every week. Most children walk into something, or run, or fall, etc. Just watch her and if she starts to complain about them or if a bubble appears above these teeth and leaks puss, then get it checked. Otherwise, the darkening or any other changes are ok. You should get regular dental checkups for her starting around age 2 1/2 - 3 usually (or when she understands instructions).
