Colgate Optic White ComfortFit Teeth Whitening Kit with LED Light and Whitening Pen, LED Teeth Whitening Kit, Enamel Safe, Works with iPhone and Android

This does work and is approved to not errode enamel so is ADA approved and sold by Colgate and Crest. The only problem for me is that I'm missing some teeth so without the partial in... And u can't use this with them in,, it's really hard to bite down on the mouth piece where there r no teeth to grip it.. but I make it work.. privately. It will make a big lightening effect.

Not ashamed to smile.

I’ve been using this product for the past couple months now and I have to say it works really well. It lasts a very long time. The pen itself is really easy to use. You have to dry your teeth to put it on and then the LED light even plugged into your phone to use. It is insanely helpful and easy and automatically turn off when the timer is done. I have noticed my teeth getting whiter throughout using this.HIGHLY REMCOMMEND

I read the reviews and still didn't quite understand that it is like paint. Super white paint that they recommend leaving on. It chips off like paint, looks unbelievably unnatural, and doesn't whiten any better than the stuff at dollar tree. I gave it 3 stars because the light is worth it and I use it with the tooth whitener from dollar tree.

The Optic White LED Light is an excellent choice for anyone looking to brighten up their smile. It’s small, easy to use, and works great.

The mouthpiece is VERY difficult to keep in place. The tabs provided are small - barely the with of the teeth. The plastic is smooth and there’s no groove for your teeth to grip so it easily slips out when even before it gets wet. Additionally, the curve of the mouthpiece doesn’t match the front teeth so your teeth aren’t just holding it in place like other devices. You need to continuously exert effort to keep it from straightening out, pulling away from your teeth and pulling those little tabs out from between your teeth.I can’t say how well this device whitens teeth - my jaw was exhausted well before the first 10 minute treatment was complete and I decided to return it.

Easy to use and super convenient!! I definitely notice a big difference when using this consistently.

Definitely made my teeth whiter. I drink a lot of coffee and it helped get rid of the coffee stains in no time!
