So i finally took the plunge with getting clear aligners (invisalign) and had my appointment on Sat morning to fit the attachments. The lower teeth attachemnts went on fine, but on the upper teeth the dentist squired something in my mouth that immediately started burning and stinging. Looking back I should have said something, but I was lying back with my mouth open, wasn't sure if it was normal, etc... and then was just in pain and waiting for it to end. Afterwards my mouth was visibly swollen (trout pout) and he seemed surprised and told me to rinse it with water and said it might be an allergy. By Sat evening it was obvious that whatever he put in my mouth had caused sores/burns, so I have burns and crusting on the edges of my mouth, an ulcer on my lip and another very painful ulcer on my tonsil where whatever it was dripped backwards into my mouth. I left phone messages for the surgery over the weekend but obvs no one was there. Couldn't eat on Sat eve, had to have smoothie for dinner. He called me this morning and was very apologetic and asked to see me. At the appt he said it's never happened before and he has no idea how it happened this time. Gave me a prescription for Difflam and said to come back in a week. I still feel shell-shocked and not sure what to do... I can't get my aligners in at the moment as can't open my mouth without the sores cracking, but don't even feel like having the treatment any more as I don't feel like I can trust him. But have the attachments all over my teeth (v painful when they rub against the sores). What should I do now?? See another dentist?? Ugh. Just want a bit of hand-holding really. I have past unpleasant dental/medical experiences and getting my teeth fixed was supposed to be a present to myself but has now turned into another source of upset/trauma...
