Colgate Optic White Overnight Teeth Whitening Treatment Pen

I like & don't like this product. I like it because it works & you can see clearly that its whitened your teeth even within a week. I don't like this product because when u use it it leaves dried up clumps of whitening paste in your mouth & on your teeth. Resulting in swallowing it which is not so pleasant. Without this one problem i would definetly buy again & use regularly

I found the gel hurt my gums and I didn’t like the feel of my teeth the next morning and I found the gel was hard to get off the next morning really had to scrub hard and sometimes wouldn’t come off till later the next night

It came in a very nice packaging which i will show you in a video.The product is very light and easy to store.The product itself was easy to use, with a few clicks you were able to get the product out of the pen and applied to your teeth.I think this is the best whitening teeth product i have used and the best thing is that it works.My teeth are definitely whiter from when i first started using the pen.I Applied the product every night for 2 weeks as per the direction.

I have tried other whitening products and have been mostly disappointed , so I couldn’t believe when this product actually worked !! It was very simple to do and didn’t have a bad taste like some others I have tried . Thumbs up from me

The package was nice and bright, useful information. Using the pen was a bit difficult, the product dries to quickly and forms a string while you're trying to apply. I wiped the pen in between uses as recommended. The solution was lumpy on my teeth as I went to sleep which is a bit uncomfortable. Slight sensitivity after 1 week of continuos use.

Easy to use with noticeable results. I really enjoyed the packaging too

Easy to use whitening treatment pen, the treatment whiten my teeth and reduced yellowing. My teeth look whiter without the sensitivity caused by other treatments

I enjoyed using the product as it have me an incentive to take better care of my teeth, although I don’t feel like I went 3 shades lighter, possibly 1 and at most 2. It felt super chalky on my teeth which I didn’t mind, but I just wish I had more instructions as I wasn’t sure if I should go back over my teeth or what. Soon I learnt not to go back over the teeth as it put holes in the liquid. I also didn’t know how much liquid was left in my pen after my usage so I was unsure if I was nearly out etc. Also when I brushed my teeth the next morning sometimes it was really white and I couldn’t scrub it with my brush so I had to use my nail to scrape off the white residue which felt awful. But all in all I enjoyed the product, didn’t make my teeth sensitive and definitely made me teeth look and feel healthier! It was also a quick process in the night! I would recommend it to someone who has sensitive teeth and only want a shade or 2 lighter!

I was sceptical about how well this product would work, and was pleasantly surprised when it worked just as well as products from the dentist. Will definitely be recommending to my friends and family, as it was really simple and easy to use. It did hurt a little at first, which is no different to expensive products I've purchased with dentists previously, but my teeth definitely became used it and it was no longer hurting after a few days.

Its a great product. I have dentinogenesis imperfecta which causes a discoloration of the teeth. At the end of the two weeks i noticed that there was a change on my teeth after using the pen

I can see the diiference when applying Colgate Optic White every night before sleep. Worth to buy and easy to use.

It was really difficult to get a layer on each tooth before the formula hardened on the applicator. It had a very strong bleach taste while it was drying. I used the product as directed for 2 weeks and didnt notice a difference in my tooth colouring.

I was so excited to try this as my teeth have stained. Easy to use, but once applied after brushing, the liquid that comes out on the brush went kind of stringy as it hit my teeth. You need to let it dry which I did and I could feel bumps over my teeth from the liquid hardening. The brush was nice, but kind of stuck together as the liquid aent stringy. Packaging is great and easy to use

I was very excited to test this product. I used it as directed. At first, it took some time for the drop to appear, more time than was promised. I'm a coffee drinker and as a result, I have some discoloration. Incredibly though, I noticed a lightening of my teeth after only one day of usage. I didn't experience any sensitivity at all, only a slight burning when I accidentally put some product on my gums. I had an appointment with my dentist a few days ago and they confirmed that I hadn't damaged my enamel using this pen in any way - so it's very safe to use. I definitely will use this product again for my teeth to look whiter.

It made my teeth look really white and healthy! It was easy to apply and I felt comfortable using the product.
