When I was a teen I had braces. When my braces came off I needed a root canal and an implant on the teeth where the bands were. I continued to wear my retainer.
Eventually, the crown on the implant came loose. I was told the torque from the retainer damaged my implant. My orthodontist, dentist and oral surgeon didn't foresee this. I stopped wearing the retainer.
Then my front teeth needed veneers because of an accident. They cracked because my bite is shifting back to what it was before I had braces. Another retainer would damage my implant. Doing nothing will ruin my smile. What to do?
