44% Carbamide Peroxide 10-3cc Syringes of Teeth Whitening Gel - (2) LED Accelerator Light - (4) Mouth Trays - (2) Shade Guide - (1) Instructions Sheet

Even after the first use I did notice a big difference on my teeth's color. It all depends on you how far you want to take it. Will buy it again.

Best whitener l have purchased. I had my own trays..so cannot comment on trays, but flavor and whiting was 5 star. Value excellent. Have bought twice.

I have been using this product for about 2.5 weeks - a total of 6 treatments. It does work - my teeth are noticably whiter. However, I have found that if I use treatments too close together, my teeth and gums get quite sensitive. This subsides within a couple days though. I also apply it with a cotton swab to minimize the amount that comes in contact with my gums.

Doesn't work as well as it claims.

These whitening syringes are very easy to use.

Incredible value however that stuff is strong! I only use it once a month however on the 3rd application I could not keep it in my mouth for more than a few minutes. I probably applied too much as it was primarily a gum burning issue. I bought a remineralizing kit from another vendor on Amazon which I used immediately after applying this product. Certainly seemed to "cool things off" and I have had no sensitivity.

Works teeth are whiter

Terrible product! It is extremely gritty and very irritating if it ever touches your gums and causes terrible sensitivity. I actually fried my gums with the tiny bit that touched and gums turned white and then blistered and painful. Tastes absolutely disgusting. I couldn't get it out of my mouth fast enough and it took a week for my gums to heal from the burns.
