The most painful tooth whitening system available. Performed by a dental technician, the Zoom whitening system can make your teeth up to eight shades lighter in just 45 minutes.

The Zoom whitening system consists of a high-concentration bleaching gel (a.k.a. hydrogen peroxide) and an ultraviolet light. The UV light accelerates the bleaching process and helps the hydrogen peroxide penetrate your teeth. The gel is applied for three 15-minute sessions for a total treatment time of 45 minutes.

Zoom whitening hurts like a motherfucker, which is why at-home whitening systems are still available. Custom-molded trays filled with dentist-dispensed gel are worn 1-2 hours a day for up to 14 days. Tooth sensitivity is less severe and should subside after a couple of days.
The Zoom whitening procedure begins with a plastic piece being placed in your mouth to hold it open (if you have a strong gag reflex, you won't last the entire procedure). A blue coating is painted onto your gums to prevent chemical burns. The whitening gel is then applied and an ultraviolet light is placed near your mouth. Protective eyewear is provided.
