Teeth whitening kits aren’t exactly what most people would call riveting. But I must say I was blown away by the entire SmileBrilliant 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 SmileBrilliant. 

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, SmileBrilliant sends you a putty impression kit, you return the impressions via prepaid packaging and then SmileBrilliant 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), SmileBrilliant 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 SmileBrilliant trays and the gel felt pretty tingly. Other than that, I had no problems with these trays, despite my shallow impressions.
