Rembrandt 2 Hour Whitening Kit-8 ct, 2 pack

Unless you're a masochist & enjoy burns all over your gums & the inside of your lips, then I would stay away. I used this on Saturday, it is now Monday & I'm still eating baby food.

I am all about comfort. I hate the drooling, slobbering, mess, nasty taste, and time-consumption of other teeth whitening products that I've used. (Crest white strips anyone?) Even though I had never used Rembrandt brand before, I was pleasantly surprised with this product. There is a special mouth tray that you mold to your teeth, you simply dip it for a few seconds in hot water (I just microwaved a mug of water as if I was making tea) and then put them in your mouth and bite down. 5 seconds later, the tray has molded perfectly to your teeth. Then you take the trays out, squeeze some of the whitening cream into the tray, and wear them for 15 minutes. I used the 2 hour program while I was browsing the internet, writing some letters, painting my nails- and there was no drooling, or extra saliva in my mouth. The trays were big enough to keep the whitening product in the trays and not oozing out into my mouth, but small enough so that I could wear both trays (top and bottom) without feeling uncomfortable. It was very easy, I am very pleased.The whiteness lasted pretty long too, I'd say about 6 months. And, I never felt any tooth sensitivity (cold/heat) afterward like I did with other products.

Have used this kit intermittently for years. I like that you finish a treatment in 2 hours, not drawn out over days. Can definitely see results after treatment.

What can I say, it does exactly what it says on the box. My teeth were quite yellow from lots of tea-drinking, and they were noticeably whiter and brighter after the 2 hour treatment. The nice thing about the product is that you use it for FOUR 20-minute sessions with 10 minute breaks in between, and the directions indicate if it starts to feel painful or sensitive, you can hold off on the next session until your teeth and gums feel better. So if you don't have a singe 2-hour period to devote to the process, you could divide it up over a few days. The directions are thorough and easy to follow, the trays mold easily to your teeth. Yes, after 2 hours your gums burn a little, but that is not surprising given that this is a bleaching product. Definitely the best whitening product available outside of a dental office setting. Highly recommended.
