4 years ago i got kneed in the mouth and fractured the bone above my front teeth ( they said nothing could be done about it). since then my teeth have been slightly lose but they have gotten worse over time. I lost my retainer and started wearing one from last year (i got a new one because the one i am now using did not fit last year but now does fit). since wearing it i have noticed that my teeth are very loose and pop if you put pressure on them. i got x-rays 6 months ago and everything was good but Im scared my two front teeth are going to fall out… will they fall out? do i need to go back to the dentist?
