So I started Invisalign on the run up to the wedding. I’m now on my 3rd tray (so 6th week of treatment) and all of a sudden I’ve developed sores on my inner lips – to the point where they feel as if they’re burning. Very red and sore all the way along (so not an ulcer it’s just sore all over)
Ive heard it’s very rare to have an allergic reaction to them and I’m baffled as to why it’s only just started now! The edges of the trays aren’t even sharp so I truly am stumped.
Im going to see my dentist tomorrow to see what he says but In the meantime I wondered if anyone else has had symptoms like this?
ive actually removed the trays at the moment – probably to the detriment of my treatment but I just can’t go on with the sore inner lips!
Up until now my experience has been brilliant with them – I’m absolutely gutted 🙁

This sounds awful 🙁 I’m certainly no expert, but a little bit of googling indicates that an allergic reaction to invisalign might not be as rare as you’ve heard. It does say that it’s rare on sites like WebMD, etc., but found some articles and threads where many post to describe symptoms exactly like yours and some extremely severe. Some state that symptoms were immediate, others didn’t show up for weeks or months. One of the articles a few commenters mention a “hypoallergenic” tray/version – maybe something to ask your dentist about?
I’m not saying this is a credible source but lost of stories in the comments on this article that you may relate to, some offer suggestions or mention alternatives to the traditional tray that you could ask your dentist about (the newest comments are from 2016): https://www.aboutlawsuits.com/invisalign-invisible-braces-warning-letter-14750/comment-page-1/

Did symptoms just start with this third tray? Maybe there’s something wrong with this particular tray?

I think it’s the trays rubbing. I had real braces for 3 years and that was torture enough, but the plastic retainer I have now sometimes rubs and I get friction burn on the insides of my cheeks and lips.

I should add, there is dental wax you can buy (it’s like $2) that you can cover the edges. Helps 1,000,000%

I’m about to start my 4th tray and haven’t had those issues. If it just started with the 3rd tray, it may be rubbing wrong, which would hopefully go away with the 4th tray. Your dentist is likely to know more though. Best of luck!

If you think it might be an allergic reaction try taking some Benadryl and see if that helps

Had Invisaligns for 2 years and I also experienced these sores. Unfortunately it is most likely because of the trays rubbing against the inside of of the lip – it’s incredibly painful but eventually goes away with subsequent trays.
My orthodontist suggested filing them down a bit or the dental wax PP suggested.
