My front tooth broke and had a post and crown done on it. Another dentist had recommended an implant on that tooth because he says I have a crack and was at risk of losing it at anytime. I had veneers done and it messed up my bite. I am planning on redoing my veneers. My question is do I really need the implant now or can I just wait until the crown stops functioning? If I were to change my veneers, would that affect that crack? Your help is really appreciated.
