was going to change my brace, from set 2 to set 3, set 3 packet says attachments, IPR, Precision cuts, I do not had any attachments on my teeth yet (due for next appointment in 2 weeks) should I be wearing week 3 ? Dentist did say either don't wear week 3 or don't go past week 3 for next appointment ! I can't remember, dentist is closed today so can't call. This would mean I was wearing set 2 for 1 month !?
