For most people, the results are long lasting. Exposure to coffees, teas, tobacco, red wines and certain other stain producing substances will eventually darken teeth again over time.
After initial treatment, some people do touch-ups every 6-8 months based on the amount of stain producing substances that they are exposed to. The ProWhiteSmile Whitening System is not a “supermarket” type tooth whitening kit and is considerably stronger than most “As Seen On TV” type kits.
The active ingredient in the whitening gel, Carbamide Peroxide is in Professional Dental Office strength (22%) and our massive 10cc syringes give up to 40 individual tray treatments. 3 times the amount of most syringe type kits sold at higher prices.
