What does the + sign mean on an Invisalign tray?

April 28, 2017
Asked By:whatinthef in Corona, CA

I recently noticed my last three trays have the + sign on them. I.e. 47+, 48+, 49+. What does the + mean? Additionally, is it realistic to assume that any dentist will remove these attachments for me when this is over? I moved mid-treatment and have not found a new dentist yet. My attachments all fit perfectly and my teeth look great so I'm not worried about it.

Hisham Kaloti, DDS (retired) says:

Your smile is very important, but your bite is even more important. Not having a proper bite can cause even more tooth and bone loss. Clear aligners may be a good alternative for you where you dont need to have fixed metal braces for a long period of time.
