Ingredients Glycerin, Carbamide Peroxide, Carbomer, Menthol, EDTAPrice $119 $149 at Smile Brilliant Teeth whitening kits aren't exactly what most people would call riveting. I must say I was blown away by the entire Smile Brilliant process and package. I wasn't aware you could get custom-fitted whitening trays anywhere other than a dentist's office, but you can with Smile Brilliant.Wearing these whitening trays is just like wearing a retainer. They fit perfectly to your teeth because they're designed using putty impressions you make of your teeth. The process works like this: You order a kit, Smile Brilliant sends you a putty impression kit, you return the impressions via prepaid packaging and then Smile Brilliant sends your custom-fitted whitening trays within a matter of days.If you mess up during the impression process (which I did; my impressions were evidently a bit shallow), Smile Brilliant will either send you a new impression kit or go ahead with the trays if they think they can make it work. In the latter case, the company will still send an impression kit along with your whitening trays just in case.To use the trays, simply squeeze the carbamide peroxide whitening gel into your upper and lower trays and slip them on. Be careful not to squeeze too much gel, or it may spill over the tops of your trays and get on your gums and tongue. I did this the first time I wore my Smile Brilliant trays and the gel felt pretty tingly. Other than that, I had no problems with these trays, despite my shallow impressions. $25 at Target The whitening kit from Lumineux is not a typical teeth-whitening kit. Instead of hydrogen peroxide gel and an LED mouthpiece, this whitening kit simply includes daily essentials for teeth whitening, which is why it's the best for sensitive teeth -- most people with sensitive teeth can't handle something like hydrogen peroxide and LED lights.This whitening kit includes Lumineux whitening strips, whitening toothpaste and mouthwash, all of which use Lumineux's patented formula containing coconut oil, dead sea salt and citrus oil. For extra white teeth, don't just use these products separately like you normally might. The instructions are explicit: Wear the strips for 30 minutes, brush immediately after for at least one minute and then rinse with the mouthwash for at least one minute.I love this kit because I have sensitive teeth and struggle to get through whitening treatments that involve bleach or hydrogen peroxide.
