Bright White Smiles Teeth Whitening Kit, 35% Carbamide Peroxide Gel for Professional Results at Home, Whiter Smile Refill System includes: 10X Syringes, Trays not included

I was in the dental field for 34yrs and this is a good product for brightening teeth. Everyone’s teeth are different shades so people with yellowish brown tone teeth will brighten better than gray tone. if you generally have sensitive teeth most likely this bleach with cause that. Go every other day or 3 days, than rub small amount of sensitivity toothpaste on your teeth and leave on or go to a 22% whitener.

I like the overall quality of the product and how easy it is to use

Seems very strong and starts to irritate gums, etc. but I like that as it means its working on teeth too !!!

I love this product. I'm 57. For the majority of my life, I drank Pepsi daily. My teeth were quite yellow. Most of my pictures show me smiling without revealing my teeth. After about a week's worth of applications, there was significant brightness. Having also lost a significant amount of weight, the teeth brightening and a major hair makeover became noticeable to all. My boss (who I rarely see) was stunned and said, look at your weight loss, your teeth and your hair. Don't worry. We're more friends than employee-employer. So her compliments were more than well received. Point is...others noticed the difference too!

This is a liquid, not a gel — it does not stay in the bleach trays or in contact with your teeth. The solution is harsh enough to cause constant production of saliva, so if you use it you have to have a spit cup on hand at all times. The syringe also sticks, so when you push on it, it sticks, then suddenly gives, shooting a quarter to a third of the bleach solution out at high speed, which then bounces out of the bleach tray and back all over your clothes. I used one syringe, and threw out the rest.
