Brush your teeth with water. For faster results, replace water with standard over-the-counter hydrogen peroxide (do not swallow).

Apply whitening gel to teeth. Twist gel pen until gel appears in brush and apply to all teeth you want to appear white. Do not eat or drink for 30 minutes after gel application.

A set of 3 Teeth Whitening Refill Pens will last 12-15 uses. Each pen contains a gel with 35% carbamide peroxide and potassium nitrate.

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.
