Very Strong 44% WTG Carbamide Peroxide 10 Syringes (3cc) of Teeth Whitening Gel - 1 LED Accelerator Light - 2 Trays - 1 Shade Guide -Instructions Sheet - May Cause Sensitivity and Gum Irritation

I drink a lot of tea, it’s a constant struggle to keep my teeth from looking brown.This comes with 2 thermoplastic teeth trays to be individually fitted after immersion in very hot water. Get it right the first time, as they don’t reform easily and tend to shrink with additional heat. Mine look ugly but get the job done.This solution was the strongest practical one outside of a dental office. Compared to others I’ve tried, this bleaches teeth faster and more thoroughly. It should get on the gums, as it will cause pain and potential tissue damage.The blue light emitter has a plastic sticker on the battery that must be removed to function. With that said, it’s impractical to use the light emitter with the two teeth trays. The usefulness of blue light for teeth bleaching is debatable in any event.Cost and solution strength were my main considerations. This option won me over and I’m content.

I have been trying to whiten my teeth for the longest. I have been using 9% hydrogen peroxide which is just about the strongest I could find. Especially once I learned it is more powerful then carbamide peroxide. But 34% carbamide peroxide is the equivalent of 14% hydrogen peroxide. I saw results after 1 treatment. This product is a definite must have for anyone wanting to whiten their teeth.

Decent price but it needs to be applied several times in order to see a difference on the teeth

I am pleased. It works well...I get compliments all the time. I've learned through trail and error that one connot floss, brush and then use this product because now you've scratched up your gums hence brings the pain snd whitening of the gums..Softer toothbush is needed. When needed....I'll brush before bed and whiten in the morning. ⭐⭐⭐⭐⭐

This was my first experience with a whitening treatment. At first, I thought I received a defective LED but after contacting customer support, I was mistaken and had not properly installed the battery. They reached back out to me the same day. I had very little tingling sensation on my gums and tongue. Not enough to make me spit it out. I used it once and could definitely see the difference, THANK YOU! My daughter also used it once so far and I can see the difference in her teeth as well. I am definitely recommending this product and for the price you cannot beat it!

I purchased this product for my teenager whom has fluoride stains on her teeth. I decided to test it out and just buy more trays for her just to have the knowledge of how to do it. It was hard to form the trays to my mouth. The first I left in the boiling water to long and it shriveled up, the second, no matter how hard I sucked in, it didn't form around my teeth like I think it was suppose to. (clue 1, this is not going to work for my daughter). Then I placed a small dot on each spot like the instructions said, and put it in my mouth. The gums on my bottom teeth come about half way up my teeth so there was no way around getting some of the whiting paste on my gums, instantly my gums swelled up from chemical burns and I was in so much pain I was under the sink and my husband was grabbing napkins and splashing water in my mouth. (clue 2, this is not for a teen). The next day I reapplied with a makeup brush directly to my teeth then put in the trays and used the light, although the instructions state the light will turn off every ten minutes so you know to push it twice for a complete treatment, the light does not turn off unless you manually turn it off. For the next two days even breathing in caused my actual teeth to hurt, and I'm no sissy, I've had braces and oral surgery without meds before, but my teeth ached with this product. (clue 3, this is not for a teen or anyone under the age of 30)Overall, I threw away the rest of the product and will just swish around with peroxide after I brush like I've done my whole life and I will not be instructing anyone to use it. I'm sure it will work for most people but it will not work for me.I'm not upset, some things work, some things don't, I learned my lesson. But I'm just saying, don't buy for a kid unless you try it first.

It's working.. but there is lots of gritty sand like particles in it. It's pretty crunchy. I tried to contact the manufacturer for customer support .. but that is not an option .I have been buying similar products for years.. and never got a gritty version..
