No, the custom trays provided with Philips Zoom Whitening are engineered to safely apply the gel to your teeth. The scalloped edges minimize the contact the whitening gel has with your gums.
Aligner trays are manufactured specifically for moving your teeth into a new position and will cover your gums. You should not use Philips Zoom Whitening gel with aligner trays due to the combination of applied pressure and gum line coverage.
CandidPro's Whitening Foam is a more gentle solution that may be used with your aligner trays.
