My clear bottom retainer cracked, think of it like this, it was going north and now, it's going east. (photo)
I got my clear retainers, bottom and top, in early march, a week after I got my braces off. I had my most recent appointment in June but after that, my bottom retainer started to crack a little but I didn't really bother me and I was going to tell the ortho my next check up because it was a small crack. I notice I grind my teeth and I could tell the top of the retainer was getting a thin layer of plastic and today, it spilt but it was odd because it went another way. Should I go to my ortho?
