|How often do you change your Invisalign trays?|
Tuesday, April 24, 2018
There are a lot of misconceptions around regarding the number of days required per aligner tray with Invisalign orthodontics.
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.

It is a common myth that teenagers are not good candidates for Toronto Invisalign treatment. Just like regular braces, teens must be compliant with oral hygiene and the use of elastics. However, using aligners may make treatment more comfortable and allow better access for cleaning.
Take a look at this video describing teen compliance with Invisalign by Dr. Jason Tam of MCO Orthodontics, orthodontist in Oshawa, Toronto, Stouffville, Markham, and Scarborough.
