Liz. Invisalign Day 31. Well trays still out so very disappointing and I still have a sore throat but hopefully the last of a cough. The good news in that my Dentist has come back to say that Invisalign will send 3 new sets of trays treated “in a different way” – there is no more information than that available so no ways of knowing what chemicals they are using in this treatment for future reference.  They release no information on their website either. Neither my dentist or I know if it was the trays or the use of retainer brite that triggered the sore throat or cough but I think it a strong possibility knowing my level of sensitivity to products. So I am now playing a waiting game for new aligners to arrive and throat to settle down.  Part of me wants to get on with the treatment but I also dread the thought of the trays in my mouth again after it feeling so unpleasant recently. So far no progress – argghhhhhh! Not even a score on the board yet.
