Will I need braces again for this tiny gap after losing retainer for 2 weeks? (Photos)

By seeing your photo, positive findings are: mal-aligned upper teeth, extruded upper anterior teeth, and gummy smile. so, the answer to your question is, no surgery is required, orthodontic treatment will correct these issues. invisalign/aligner will give better results as compared to braces...

With the help of TADs and braces reopening of space and retraction of anterior teeth is possible. But remember this mode is time-consuming. Visit an orthodontist, a general dentist can not do correction by this mode he is not a specialist for that.

There is an asymmetry in the jawline. First thing is to identify the reason for that (bone, muscle or soft tissue). So for that OPG and Skull front view x-ray is needed for cephalometric anysis.
