For optimal sensitivity relief, brush teeth using AO ProToothpaste Sensitive and apply AO ProVantage Dental Gel to gums for 3 days prior to your whitening treatment. We recommend the pre-whitening treatment first thing in the morning, after lunch, and before bed.

No, we do not recommend whitening your teeth immediately after using the Pre-Treatment routine. For optimal whitening results, wait at least an hour after use of our pre-treatment regimen.

Teeth whitening is accomplished by using either a peroxide or carbamide peroxide gel, both break down using oxidation as the method of whitening teeth. The higher the concentration of peroxide, the faster whitening but unfortunately the higher the concentration is associated with more pain and sensitivity to the teeth and gums. Our take home whitening kit contains 35% carbamide peroxide along with potassium nitrate to help minimize teeth sensitivity. For individuals who have experienced teeth and mouth sensitivity when whitening, we recommend our clinically proven AO ProToothpaste Sensitive and AO ProVantage Dental Gel as a pre-treatment.
