Professional Teeth Whitening Strips 21 Treatments - Enamel Safe - Non-Sensitive Formula - Pack of 42 Peroxide-Free Strips - Teeth Whitening Kit + Mouth Opener Included

I have tried a number of strips from Amazon over a long period of time and came across these advertised, as they were a new product i thought i would try them out too, previous purchases include Crest Strips but they always created painful sensitivity issues in my teeth.No such problem with these strips from N3cessity. Super easy to use with good instructions if you havent used strips before, no overly strong taste and no problem with lots of excess residue i have found with other teeth whitening strips.The key point for me was sensitivity and of course results. The strips are definitely teeth friendly! I have used for over a week with no problems at all, and my teeth are sparkling, i drink a lot of tea and am a big fan of sauces etc so my teeth take quite a battering at times hence i use a lot of strips to whiten them regularly.They have been great at removing a couple of spot stains and i would say two to three shades lighter with results you can see after the first go.I will be purchasing again as soon as i have used this box most definitely. Great product with excellent results!

I've tried several teeth whitening products over the years, but these teeth whitening strips are by far the best. After just one week, I noticed a huge difference in the brightness of my teeth. They're easy to apply, stay in place, and don't cause any sensitivity. I'm so pleased with the results and will definitely be purchasing again!

These are good quality whitening steips that are easy to apply and relatively comfortable to wear. They don't leave my teeth feeling sensitive but so make a noticeable difference in the whiteness level

The strips are backed with a gel which spreads over and between your teeth when you press the strips on. They stay in place well, and are a little fiddly but not difficult to apply. I've been using them a few days and I think they are already working. I wish I'd taken pictures, as I was expecting it to do less than it seems to have so far already. It's not a massive difference but I'm pretty sure they're getting brighter.They also come with a tool that spreads your mouth open. It is a bit weird and you definitely wouldn't want to use it with dry lips, but it does make them a little easier to apply. It especially helps with drying your teeth out before applying the strips.
