I had braces before in a series of treatments as we waited for my permanent teeth to grow in, beginning in elementary until 9th grade. After I got them off, I had a permanent retainer on top and bottom. I broke the top retainer eating ice 2 years ago.
I got lingual braces today on the top only to straigten the damage from the broken retainer and so far, so good. I'm used to having something behind my teeth bc of the retainer and the best part is, you cant see anything! No metal mouth! I do have to wear an invisalign type retainer everyday, but it's not too bad either. My treatment is scheduled for 6-8 months.
My dental insurance covers orthodontia so my out of pocket expenses were within my budget, so I'd say lingual braces are definitely worth the extra money and the pain level is minimal.
