After making an appointment for dental implants, I was recently told that there wasn't enough space for a dental implant. Now i am being referred back to my orthodontist to create more 'root space' for my lateral teeth. How will this procedure be done? I am already missing 2 of my lateral teeth and I am afraid they will need to pull a tooth out. Will a tooth extraction be necessary since I'm already missing most my front teeth. Also will I still be able to wear my retainer with fake teeth?
