I literally had my appointment to fit my 1st trays yesterday- but on Monday I had a crown come loose. My orthodontist sent me to my dentist before fitting my bottom aligners. My dentist says he might not be able to reuse the same crown. Would I need ALL new trays? Will this double my cost? Could I just pull the tooth and have a prosthetic fit after Invisalign? It's not an anchor tooth. I've been saving for this for years and I can't believe I just wasted all that money for nothing. Please help.
