We all lust after an aligned, bright and picturesque smile! Now you can achieve it all at once with Invisalign – the new way to whiten! You can whiten your teeth while you straighten your smile, using the new Invisalign Professional Whitening System, powered by Opalescence – now available at Walt Orthodontics!


How Does it Work?

The professional-grade whitening has been designed to be used with your Invisalign aligners.

Preparation: make sure not to use your professional whitening system during the first two days of a new aligner set, due to sensitivity. 


1. Load the tray with the gel one-quarter to one third of the height, from one cheek-side of the tray to the other.


2. Insert the tray in front of a mirror and check for any displaced gel outside of the tray. Wipe the gel away – do not swallow.


*Wear the Opalescence PF 10% Mint whitening gel for 8-10 hours or overnight, or as directed by the Walt Orthodontics team.*

3. At the completion, remove the tray, rinse and brush the gel from the teeth (do not swallow).


4. Clean the tray with a toothbrush and water after use and store in a dry container.


In-Office Whitening

For those patients seeking a quicker way to achieve white teeth, we office in-office Zoom Whitening. The whole procedure takes about 1-2 hours and you will instantly see a change of up to 8 shades.
