Zoom!® uses a highly concentrated peroxide whitening gel and a proprietary blue light which stimulates the whitening process. This system allows for immediate results, as opposed to the gradual change of at-home whitening methods.

The procedure begins with a short preparation to cover the lips and gums, while leaving the teeth exposed. Your provider then applies the Zoom!® whitening gel and sets the Zoom!® light. As the hydrogen peroxide is broken down, oxygen enters the enamel to break up stains and discoloration, leaving the structure of the tooth unchanged. The gel remains in place for 15 minutes while the light is activated.

Typically, the gel is applied for three 15-minute sessions of light activation, for a total treatment time of 45 minutes. Afterward, a fluoride paste is applied to the teeth to help reduce sensitivity.

Please note that artificial teeth will not respond to conventional whitening agents. In addition, patients with a strong gag reflex may have a difficult time undergoing the entire procedure. Zoom!® is typically not recommended for patients under 13 years of age, as well as pregnant or lactating women.

Your provider may recommend one or more additional services during your visit. For additional pricing and payment during your visit, please see separate service listing on Sibi Health or ask your provider.
