Bright White Smiles - Teeth Whitening Gel Refill Kit - 10 Tubes 44% Carbamide Peroxide Tooth Whitener Formula

Definitely works well and costs way less than the dentist charged for the same product.

Obvious results after one use. This formulation is strong!

Haven’t used long enough to know if it actually works. I do know that it will burn your gums.There is no fine tip included. There really should be a pointed tip. Hard to fill bleaching trays with no tip. So, overfill gets on your gums and now it burns. I’ll wait a few days before I can use again.

The product doesn’t work well. In addition to the dispenser being poorly designed so that you end up wasting most of the gel, the gel turned to liquid after about a year. As a liquid it doesn’t adhere to your teeth, so it doesn’t work. Because the purchase is for a bulk amount, a single person won’t use most of the product in one year’s time’s, nor will two people. Therefore, most of the product is wasted.

I had been buying whitening from my dentist, no problem. But after finding these for less $, thought I'd try. They made my teeth SOOO incredibly sensitive going to throw them away. World of difference!!

Love this product it does what it says! I use a UV light as well that came with another kit so I was able to apply the gel by brushing it on although you could just apply it to a tray but my trays weren't designed for that. I left it in for 15 to 20 minutes is recommended and I noticed a significant change in the shade of my teeth.

Am using this gel as a refill for a very popular selling LED and tray kit here on Amazon. The kit came with what was advertised as 35% strength gel, but it clearly was not. This 44% gel packs much more punch, I can feel it, the results are much clearer and quicker after just 2 treatments than the entire treatment with the previous kit's gel.Thank you to Bright White Smiles for delivering what is clearly one of the few gels *actually living up to its strength claims*. The only other gel in my experience that was as potent as this was the professional effects gel from CRST Whitestrips which is an extremely expensive product, their top-of-the-line. Highly recommend to everyone who can handle tooth/gum sensitivity and want strong rapid results. The quantity of whiteneing gel in this pack represents a very strong value and it works.
