I have had my braces off for well over 2 years, 2 months, 2 weeks and 5 days. Almost immediately following my freedom I enlisted into the United States Air Force. I completed basic training and my training for my job "Security Forces - Law Enforcement" and was promoted to A1C Right out of basic. Fast forward to about a year. Shortly after a deployment I flew home to my home town where my family and friends were "San Diego, CA" I had noticed one night while in town that my upper Hawley retainer had snapped into two. How did it happen I wish I knew so I could avoid it ever happening again. So I figured I was back in town maybe I could stop by the orthodontic office to find out that they had closed there doors. So I haven't had any luck and I had broken retainer that I couldn't use. Fast forward to today, I have been medically discharged from the air force. Return home to San Diego, CA and now I have some issues or concerns I guess would be more like it and would like some opinions.
- I Found out that while I was gone for a year the orthodontist office re-opened. Guess they had a problem with the people they leasing the building out from. So they are back open. Now the question is. I have a new dentist I go to who also specializes in orthodontics. Should I talk to them to see if they think I need braces again or should I go back to the original ortho and see what they say. Meaning if I need re-treatment will they treat me all over again without me forking out another three grand.
Below are current pictures and captions with my concerns.

Front shot of teeth not lined up like they were when the braces first came off.

Lower shot, the front four teeth seem to have shifted a little thus causing it hard to floss in that area once again. Also there was a molar that was removed due to extreme infection causing severe pain. How did it get infected I don't know but it was removed. Now there is a gap where the molar used to be.

Uppers look good except for the molar in the far back right (left in photo) which is tilted quit a bit facing outward.

Closer front view showing the closed bit with the midline not in line like it was once braces were removed.

Midline questions.
