Its 38 percent solution of hydrogen peroxide gel contains a unique patented component called PF, a mix of potassium nitrate (reducing the risk of sensitivity associated with tooth whitening) and fluoride (the enamel-strengthener which reduces the risk of cavities). Reputed for being gentle on sensitive teeth and gums, the Den-Mat Sapphire Chairside Whitening system combines a 25 percent solution of hydrogen peroxide gel with a desensitizing enhancer. After these two ingredients are painted onto the teeth, a light known as a Whitening Crystal is positioned directly in front of the teeth for 30 minutes, after which both gel and desensitizer are removed.
The teeth are then checked for whitening progress and, if necessary, bleached for an additional 30 minutes.
