5 XL 38% High Intensity Teeth Whitening Gel Syringes - USA Dental Lab Direct - Sensitivity Free Carbamide Peroxide Tooth Bleaching Gel w/Remineralization Gel

I am SO in love with stuff! It is amazing. You get a lot with this and it goes a long way. Honestly, after one use you will see a difference. I have been able to use it daily for about a half hour right off the bat with very little sensitivity! Not messy at all and uses very little product because of the wonderful little attachment that comes with it. I love it! Definitely recommend this and it is as good as anything you can get from a dentist!

Good product and does the job. It did make my teeth sensitive though, but addressed that with Sensodyne toothpaste.

I didn't realize that I needed a dental tray ... had to purchase separately later. Still using one syringe multiple times. Very minor results so far. Not irritating my gums which is a plus. Could have got a better deal elsewhere.

My second order. Only had to use the blue one time. No gum pain. Haven't gone more than the recommended 40 minutes for a single treatment. Works great, whitens beautifully. First order got my teeth to where I wanted, second order for maintenance. Buy and use with confidence. Update July 26, 2016: I use for 40 minutes once every 10-14 days for maintenance. Great stuff.

This doesn't work at all. I feel like its a scam.

I have tried MANY teeth whitening. Some have worked well. This one works Amazing. Super white.. And I love re-mineralizing syringe. I wore mine to bed and let it sink in. No teeth sensitivity.. And I use sensodine. Highly recommend

If you have sensitive teeth, this tooth whitening kit is not for you. It works well, but I'm unable to use it as its unbearable on my teeth. I've tried to use it twice, but lasted less than five minutes.

I bought this recently and was nervous to try it because I have sensitive teeth. Tried it anyway, and was so pleased with the results after the first application! I was amazed that I could see a difference already and so far it has not altered or affected the sensitivity at all! I will definately buy this product again! Plus I had to email the company and they were a pleasure to deal with too!
