Review on Greephil Whitening Effective Sensitivity Beautiful by Richard Gonzales

teeth whitening gel contains 35% carbamide peroxide, the same ingredient as the dentist. It has a very mild mint flavor. Very easy to use, much cheaper than whitening gel bought at the dentist. You dry your teeth, apply the gel to the tooth surface, applying it only to the teeth and avoiding the gums. Keep your lips parted for a minute to allow the gel to dry and wait 30 minutes to an hour before brushing your teeth. Simply apply once or twice a day. Like all teeth whitening products, it does not work on anterior fillings, veneers, or crowns. You will see improvement within a few weeks and most will see maximum results if you use it daily for 6-8 weeks. You can use the gel 3-4 times a week to maintain the whitening effect. Someone with heavy tobacco stains and coffee drinkers won't get as good results. I have been using this product once a day for 2 weeks and I can already see the difference in the color of my teeth.
