Need it on an ongoing basis
I tried it as a one time purchase first. Then realizing that my daily habit of drinking coffee wasn't going anywhere, I subscribed. Very glad that I did. One less thing to do. And for sure I will be using it on a regular basis.

Do not recomend
Did not whiten my teeth barely AT ALL. I followed instructions to a T. And although they had whitened my teeth for a little, it only lasted maybe half a day before the results wore off. I wish I could get my money back and I simply wish I stopped trying after the first round, so I could maybe return it. I had high hopes until the first round of whitening. Then I was just hoping that it would get better after the next couple rounds of treatment. No. Don’t waste your time

Product missing
I went to buy this instore and when i got home to try it out i opened it up to see the actual product wasnt even in the box only the applicator. The box itself has enough weight to where it didnt feel empty so I didnt bother second guessing. I wasnt even able to give it a full review of my own

Just....no.
I expected more from this product. First the brush isn't right to whiten the back of the teeth it only covered part of the back before it got awkward and irritating. Then this weird crust on my teeth like expired cheap left in the sun finger nail glue. It didn't come off very easy. It took 8 minutes to get the crud off my teeth.

Do not buy do not waste your money
This is the worst teeth whitener I have used. The brush dries out within one tooth I followed directions to the tee. Each time you try to do it the brush is so dry and after using the complete tube, my teeth are no wider whatsoever. I do not recommend this. You are wasting your money.

Works when you have realistic expecations
After realizing my red wine and coffee has caught up with me, I bought this as a quick fix. Application was easy and not messy. After the first day (3 applications), my teeth weren't magically and completely whiter. However, the stains were totally gone. My children noticed a difference without me telling them about the product. I plan to keep using this product for the remaining days as directed. Also - Although I have VERY sensitve teeth and can't use whitening gel/trays or strips, this did not bother me at all.

Super disappointed
I had high hopes for this whitening pen but unfortunately it was just so difficult to use that it completely ruined the product for me. I’ve used other whitening pens that did not have this issue but the product gets hard and messes up the bristles, making it difficult to dispense properly and apply to teeth. It also has trouble staying on my tooth until it dries. I didn’t think I had sensitive gums because I’ve never had an issue with my gums with any other products but when it would barely touch, my gums instantly burned. I’ve only used it for two days but I don’t even want to give this product a chance anymore because it’s so annoying to put on 😩

Super!!!
Could tell a difference after the first day, have to apply 3 times the first day and 2 times on subsequent days. Tip makes it possible to get in between teeth where it is hard to get whiteners.

Worked great!
[This review was collected as part of a promotion.] I normally use crest white strips which normally take a couple weeks to see an improvement. With this product there was noticeable improvements in just a couple days.

Great Whitener without Sensitivity!
[This review was collected as part of a promotion.] I've tried many whiteners and none have worked as well as this Colgate Optic White Express pen kit. My teeth look whiter and I did not experience any of the terribly uncomfortable tooth sensitivity that usually accompanies whitening strips. The only thing I would change is it's a little difficult for me to apply with having to dry your teeth and gums beforehand, but I don't think that can be helped. It even Seemed to work on my dental work where I have a chip in my tooth, And no other whitener has done that in the past

Colgate Optic White Express Whitening
[This review was collected as part of a promotion.] I've been using the Colgate Optic White Express Whitening Pen, and it's quickly become one of my favorite whitening products. It's super easy to use—just apply before bed, no rinsing required! I noticed a difference in the brightness of my teeth after just a few days of consistent use. The pen is also compact and convenient, making it easy to take with me when I travel. Overall, it delivers noticeable results without any sensitivity issues, and I would highly recommend it to anyone looking for a quick and effective whitening solution.

So far so good! Seeing improvement
[This review was collected as part of a promotion.] I tried this product for two weeks and I’ve noticed an improvement of the color of my teeth. I drink coffee so I know that contributing to the discoloration. This product definitely made me feel more confident because I feel like my teeth are less yellow after using it consistently. I think this is a great product if you want to whiten your teeth gradually especially also if you have an event coming up and willing to put in the work.

Fast results!!
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I use this product every night for 7 days straight. Each morning I would brush my teeth and notice a slight change in color getting whiter with every use. I am very satisfied with the results and plan to continue using this product. I have use the strips in the past and this is so much easier to use .

Excellent Pen
[This review was collected as part of a promotion.] I’ve always been a bit skeptical about teeth whitening products, but the Colgate Optic White Overnight Teeth Whitening Pen has completely changed my mind! After just a few nights of using it, I noticed a significant difference. It’s super easy to apply before bed, and I love that it’s designed to work while I’m sleeping – talk about multitasking! The pen is very user-friendly. You just twist the bottom to get the perfect amount of gel on the brush, then paint it on your teeth. No mess, no fuss. I didn't experience any sensitivity, which has been an issue for me with other whitening products in the past. The taste is pleasant, and the formula dries quickly, so it doesn't feel uncomfortable at all. I started seeing noticeable results within a week, and by the end of the 35-night treatment, my teeth were significantly whiter and brighter. It’s really boosted my confidence in my smile. Plus, the compact size makes it perfect for travel, so I never have to miss a treatment.

Does a good job
[This review was collected as part of a promotion.] The Colgate Optic White Express Whitening Pen is easy to use and convenient for on-the-go touch-ups. It noticeably brightened my teeth after consistent use for a week, though the results were not as dramatic as I had hoped. The taste is mild, and the application is straightforward, but I wish the whitening effect lasted a bit longer. Overall, it's a decent option for quick whitening but might not be enough for deeper stains.

Meh.
[This review was collected as part of a promotion.] Strong brand name, but no noticeable difference in my opinion. I took before and after photos and used as directed but I don’t think there’s a truly noticeable difference. But I hope to see it over the second week where I continue using.

Easy and Fast Way to White Teeth!
[This review was collected as part of a promotion.] I cannot extol the benefits of Colgate's Optic White Express pen emphatically enough. It has whitened my tea-stained teeth so well that people ask where I went to have them whitened! I love the convenience of the pen, the speediness of the results, and how much easier it is than using strips! Also - did not make my teeth sensitive. Leave it to Colgate to make such a fantastic product.

Great whitening Pen
[This review was collected as part of a promotion.] This started working from Day 1 and I saw a drastic improvement in my teeth color. Though not 100% white but would be over the time
