Invisalign side effects are mild
Some patients have stated mild side effects such as, feeling pressure, soreness and a slight lisp when they first start wearing their Invisalign trays.
Pressure and soreness are evidence that the Invisalign trays are working to straighten the teeth. These side effects are temporary and will decrease with time as the Invisalign trays do their job and the teeth shift into their proper place.
If you focus on results, what you want to achieve, side effects are minor, especially in comparison...
