Ask your Oshawa Orthodontist - How Often Should I Change My Invisalign Braces?

There are a lot of misconceptions around regarding the number of days required per aligner tray with Invisalign orthodontics.

How often do you change your Invisalign trays?

The truth is that the most important factor in how often to change the tray is how much movement is programmed per tray.  Imagine the following two hypothetical scenarios:

A.  2 degrees of rotation for one tooth 
B.  4 degrees of rotation for one tooth

Scenario A requires 2 trays to complete the 4 degrees of rotation.

Since we reasonably expect 2 degrees of rotation per week, A would allow for weekly aligner changes whereas B would allow for aligner changes every 2 weeks.  The net movement in 2 weeks is till 4 degrees.  Therefore, the more important thing in Invisalign treatment is the total treatment time, rather than thinking about how many trays you have.
