I asked orthodontist for night retainers,20 yr old retainer broke.Orthodontist sold me on Invisalign.Finally admitting to mistake. She wanted to correct my bite,upper teeth pulled down so much,created gaps,roots showing, changed teeth shape & smile. Placement of upper teeth sit on lower lip.Constantly locking teeth. I had beautiful smile without gaps. She wants to bring teeth back to original position using Invisalign trays backwards. Is it possible? Correct gaps? lost trust. looking for new doc
