A simple 3-step whitening process:

STEP 1 Brush your teeth and apply desensitizing solution to your teeth.

STEP 2 Apply a small amount of the whitening gel on your teeth.

STEP 3 Place the mouth piece in your mouth and turn it on for 10 minutes. Use it for 3 to 4 nights in a row, with a week break between treatment, until you have achieved the desired whiteness.
