I lost my invisalign retainer at least 3 or 4 months ago and I’ve been irresponsible enough about it to not do anything until now. I still wear the upper half of my retainer which keeps my top row of teeth aligned, although my bite has significantly changed because I’m missing my lower aligner.
I want to buy a new one desperately, but I don’t have much money and what I do have I am saving up for college (which I will be attending in less than 2 months). I’m concerned because I’ve heard the cost for molds, etc will be around 300$!
My main questions are; How will my orthodontist be able to replace my lost retainer now that my teeth have moved?
and… How much will it cost?
Braces on the bottom half of my mouth would be so expensive… and my parents are definitely not willing to fix my mistakes so it’s up to me
Pity/help me!

JUST CALL THE DENTIST AND ASK HIM/HER?
So have you completed your treatment and just wearing rets? If so yeah they would cost 275-350. And they MAY be able to move them back to where they were but it would require a commitment from you and it would depend on how much movement had taken place. I would think if you could wear new rets then get them if not save save save and then re do your treatment.
Retainers can be expensive. In some cases, they can reach at least $250 per set. However, nothing could be more costly to you than losing the progress you have already made.
