Hi iam 27 and still have one baby tooth .. I went to doctor and c said that the roots of that tooth is really weak and I should remove it .. and they will do this teeth brideging thing ....but because its my front tooth I am really scared ... is it possible to keep that tooth ...since there is no big problem with it ....its just when I tap on it ....its pain a little bit ....but if I keep it that way will it infect other teeths .....
