Invisalign is an amazing and effective treatment option to cosmetically align teeth. However, it only works if the teeth receive constant force. Leaving your trays out for as little as 6 hours once a week can negatively impact your treatment outcome. The fit of the next tray may also be compromised if you do this. As a result, your entire treatment can go off the rails. If this happens the length of your treatment will be extended, the predictability of the results can be compromised, and it may even lead to more fees to make it right. In short; if you want it to work, leave them in.
