To Get Braces or Not to Get Braces: Second Round For My Teeth? (photo)

Go back to see your orthodontist who did your work.  Fess up and tell him what happened and ask what to do.  It may not be too difficult from what I could see in photo BUT after you get it fixed this time DON'T fail to wear your retainers.  Just to make sure, I would recommend a bonded in permanent fixed lower retainer that you can't forget and can't lose, because you can't take out,  Don't worry, he has seen plenty of cases like this already so he won't be surprised.

Current research shows that extraction of your wisdom teeth alone won't prevent relapse post orthodontic treatment.  Proper retainer wear is the only way to ensure stablity of the teeth.  That being said, you have various options to correct your smile depending on the results desired. Your best bet is to go see a local orthodontist for a consultation to discuss these options (consultations are usually free).  I would also recommend seeing your general dentist because in the photo it looks like you have a "black traingle"  between your top two front teeth which can sometimes be an indication of periodontal disease.

You describe shifted and slanted teeth, but it is difficult to access this with the photo you submitted.  I can only guess that your problem is not severe and may be handled with braces or Invisalign.  We retreat many people who had previous orthodontics and didn't follow through with good retainer ware.  Many of these can be successfully treated with Invisalign.  You will have to check it out with a local orthodontist.  Good luck.
