Fairywill Teeth Whitening Kit with Led Light for Sensitive Teeth, Professional Teeth Whitener Kit, 35% Carbamide Peroxide 3ml(3) Gel with 5X Blue Light Accelerated, Enamel Safe Teeth Bleaching Kit

This teeth whitening did not make my teeth sensitive. The directions said to put in for 20-30 minutes. I opted to do 20 mins for the first time. I had no sensitivity but still had great whitening results. I did it for a 2nd time 5 days later and still no sensitivity.

Wow! I’ve never sent in a picture before in a review, but this worked so well after only one use I had to send before & after photos! I received it quickly, and the instructions were very easy to follow. I will definitely buy this again!

I really like this! I’ve always tried to whiten my teeth, but I never saw any noticeable results. Other whitening products always left my teeth so sensitive so I’d eventually just stop using them.I honestly didn’t think my teeth were this yellow!HiI saw noticeable results after the first time I used this. The top part of my teeth and the area where you floss are still a little yellow, so hopefully that starts to lighten up. && I don’t taste it... I mean you have a mouth tray in, so I don’t know how that becomes an issue.Overall, I recommend this product. I’m definitely going to keep purchasing.

A great all-in-one set that was very easy to use. I have been using daily for about 20-30mins and am already seeing a difference. I especially like the color chart that it comes with so you can monitor your progress. Doesn’t cause any irritation and the blue light is comfortable to wear.

Got this for my teenage daughter. She was pleased to see noticeable results the first use, and has it has been easy for her to use without making her teeth sensitive. Comes with a guide to monitor your progress, which is great. We will definitely get her the refills when it's time again.

It DOES indeed whiten and at a good price. My teeth are quite stained from drinking several cups of black tea every morning. Excuse the somewhat unflattering pictures. I tried it every evening for 3 days and did notice a difference in the dark stains on my. lower teeth. Then I waited a few days and did a fourth round. I noticed a sensitivity afterwards and if the product touches one's lips or gums, it leaves them very sore. The second issue is that, like many whitening products, it leaves the teeth slightly translucent. I found that the sensitivity was resolved if I whitened my teeth in the evening and then did oil pulling (with coconut oil) first thing in the morning. I haven't found a good nHap product to use in tandem (because I love my auromere toothpaste) but I understand it helps remineralize the enamel after whitening.

Wow! 3 shades whiter in one 20 minute treatment! I'm impressed. I am a smoker and coffee drinker so I was at about a 9, now at a 6. I have extremely sensitive (hot/cold/sweet) teeth. I didn't experience any increase in sensitivity but did order a remineralization gel and used that about 2 hours later just to be safe. Will definitely reorder again when needed.

Other than my saliva and the gel mixing making my tongue burn, it's a nice product, it did help my teeth. This is my first use and will continue to drive it
