Works well After using this for about 5 days I noticed my teeth looked whiter. I don't like the taste it leaves in my mouth, but it works.

It's like using acid to brush your teeth. I've always used Colgate products, but I regret ever touching this one. After the first use, my mouth hurt, especially my gums. I went to bed in pain and woke up to find blisters all over my gums. It was four days before I could eat anything even remotely solid, or brush my teeth. My dentist said he had several other patients who suffered similar injuries from Optic White. I basically had chemical burns inside my mouth. The taste buds were burnt off my tongue, and I had tissue damage on my gums and the roof of my mouth. I found HUNDREDS of stories similar to mine online. This product should not be on the market.

Love Colgate but did not see a big change after a month of use.

I really like this, I like that it is a bit gritty, and I feel that it really cleans my teeth. I only use it once per day and a regular toothpaste the other time though, to save money and to not be too harsh on my teeth.

The tooth paste is decent. But i didn't notice any whitening effects from the tooth paste.

I love this toothpaste! Ive been using it for about a week now and i can definetly see a difference with my teeth! I love how minty and strong it is!

The only toothpaste my husband will let us buy. He claims they alleviate his canker sores in his mouth. I'm not a believer but I do love the product!

This product works! After a few days you can really start to see a difference. The only part I don't prefer is the taste of the hydrogen peroxide but I think that is what makes it work so well so I will deal with it.

I can't use this on a regularly basis as I have sensitive teeth. I don't mind the taste. Since I can't use it every day can't really tell about the whitening part. Check out my U tube channel, ravercat4

after just a week I did see a difference in the color of my teeth very white great product, friends and family noticed as well I got a lot of compliments on the appearance of my teeth it actually works!!

My husband is using this right now. after three day we can see a difference.

Didn't really see a difference. Have used lots of whitening products and I found this the same as others. Packaging is eye catching and so is name. Usually love stuff by this brand and may continue use but it's not as effective at whitening as it states

It works okay. I really didn't see a dramatic change as far as the whiteness in my teeth. But, it makes my mouth feel very clean and refreshed.

This toothpaste is fabulous! The whitening effects are very noticeable and people have asked me how I've gotten my teeth so white! It is very foamy and has a great mint taste that I like.

I received the Optic White System compliments of influenster! I have been using the optic white toothpaste for almost a year now, again i got that a few months ago from influenster and i absolutely love this toothpaste. It leaves my teeth feeling super clean and fresh and always a bit whiter. Now i use it with the whitening pen and toothbrush and i have been able to see a difference, my teeth look whiter every week. I highly recommend these products!
