The kit contains whitening gel, 2 thermoforming trays, a blue LED light, remineralizing gel, and a teeth shade chart. The gel provided is sufficient for application over 7-14 days. Depending on how white your teeth are, and on your personal preference, you may be satisfied with the results after just 2-3 days of application. In our experience, few people go over 7 days. Our kit uses 36% carbamide peroxide, which we believe is more effective and safer for your teeth and gums - especially if you're sensitive - than some hydrogen peroxide kits.
The most common mistake when doing the whitening, is that people put way too much gel onto the trays. Remember you ONLY need 0.5 ml per tray. That's very little. If you put too much, you not only waste it, but it can go up and sit on your gums, which you want to avoid. How much is 0.5? Look on the syringe - it's only 1 little demarkation line. Alternatively, it's about 1/10 of a teaspoon!
Remember not to eat or drink any staining foods for at least 4 hours, preferably 6 after teeth whitening. Even better: why not try a 'white diet' for a week? Check our blogs for tips. Don't worry - it's also all in the instructions - and if you have questions - call our customer support! Happy whitening.
