●What is the teeth whitening process? - Teeth Whitening is actually a bleaching process that lightens discolorations of tooth enamel. Our system uses an effective whitening solution retained in 2 thermoforming trays (1 upper arch, 1 lower arch) that are worn over your teeth for only 15 to 20 minutes per day (In most cases, you will see results within only one week) until you have reached your desired level of whitening. Our product is a 44% carbamide peroxide solution which allows the shorter period of time for results. In comparison, a 16% solution needs to be in your mouth 45 minutes to an hour for the SAME RESULTS. Now you can get professional quality dental whitening treatment without an expensive trip to the dentist! ●How it removes stains? - Our system will remove most stains with a gentle action that whitens your teeth. As the active ingredient in the gel (carbamide peroxide 44%), is broken down, oxygen acts upon the stained organic deposits, which oxidizes them into a white color. This process makes the overall tooth color closer to its natural unstained color. Your tooth structure remains unchanged. Years of clinical tests have demonstrated the safety and effectiveness of this system. Over 95% of people treated achieve some level of tooth whitening. Crowns, bridges, bondings, and fillings do not lighten ●Is the whitening process permanent? - For most people, the treatment will last for many years. Your teeth have become stained in the first place from consuming foods and beverages. Upon the completion of your initial bleaching process, your teeth are restored close to their natural white color. Exposure to foods, drinks (especially coffee, colas, red wines), smoking and other consumables will gradually darken teeth again over time. You may want to periodically bleach your teeth. After an initial treatment, most people do touchups about once every 6-12 months. Note: Instruction in pic 6
