INSTANT WHITE SMILE'S optimized 20cc 36% Carbamide Peroxide Teeth Whitening Gel syringes with 1 Remineralization Gels- no trays

I had tried the 44% and had a problem with that strength causing a lot of pain so I read some reviews on the 35% and it was also recommended by a YouTuber that had very sensitive teeth. She swore this was the only stuff that didn't cause her to have pain afterwards. I used it last night for the first time and left it on for 18 minutes. Definitely made a difference in the whiteness of my teeth, so five stars for that, sadly within a few hours I was in agony, and even had a hard time sleeping from the pain. My teeth feel better today but still a little sensitive. Just wanted people to be aware that this stuff is very strong. I'm going to try the 10% and work my way up. Great product for those who don't have my problem.

I like that this product was made in the USA. I saw results after the first use. It's easy to apply in the mouth trays with no mess. I did experience alittle sensitivity, but that's only because some of it got on my gums After the first day it went away. I will be ordering this again.

I'm a dental assistant and this stuff works, I also like the desensitizing gel.

Excellent value. Saved me tons of money on supplies for my bleach tray. This would have cost well over 50 dollars at the dentist.

Recomendado

May cause sensitivity to teeth.

works best with a tray. Very effective for whitening
