3DWhite Teeth Whitening Pen – Easy to Use, Erases Surface Stains – Up to 75 Uses per Pen – Convenient, On-The-Go Teeth Whitening Solution

I RARELY give anything five stars. I was skeptical of this pen, but bleaching trays - like Opolescence Go - are 1) very expensive, 2) caused me a lot of pain due to teeth sensitivity, and 3) left the bottom 25% of the tooth unwhitened. So, I bought this pen. In ten days, doing four treatments per day, my teeth were uniformly whitened top to bottom with no sensitivity problems. And for much less money than trays. I understand different people have teeth that respond differently. For me, it was really amazing to see the quick and complete whitening with no pain in 10 days.

Very good product that delivers exactly as advertised and helps achieve fast results. It is easy to apply and very convenient to use. Overall, it provides reliable performance and good value.

Like many people, I’ve tried just about every teeth whitening option out there. I’m not walking around with pearly whites—but I did notice a difference after about a week of consistent use with this pen. verall, this is a simple, convenient way to brighten teeth, especially if you’re focused on the front teeth that show when you smile. I’ve never loved trays (too uncomfortable) and strips tend to get messy and unpleasant over time. This is a brush-on application, which makes it much easier to use and more targeted. I mainly applied it to the front teeth, let it sit, and avoided eating or drinking for about an hour. It fit easily into my routine, and I appreciated not having to deal with bulky or awkward whitening systems. Pros: Easy, paint-on application (no trays or strips) Great for targeting visible front teeth Convenient for quick, daily use Noticeable whitening with consistent use Cons: Some tooth sensitivity (I took a day off to give my teeth a break) Requires consistency to see results Results are not "dramatic" Best for: Ideal for anyone looking for a simple, low-hassle whitening option, especially if you want to avoid trays or strips. Bottom line: I’d give this good marks for both ease of use and visible improvement. Set realistic expectations, but with consistent use, you should see a difference. I’ll continue using it.

The Crest 3D whitening pens are convenient for quick touch-ups and overall whitening. I pretty much use only the pen now because my teeth are sensitive, and I don't feel like I'm wasting money on pricey strips when I can use the pen for a shorter period to prevent sensitivity. I like that I can get this between my teeth to remove coffee stains. This is my 2nd pen from Crest. They're easy to use, and brighten my smile fast.

Very effective when used regularly.

Using this daily and not really seeing much in terms of results. Maybe I need to be using it more frequently throughout the day. Tough to do when you're trying to drink a lot of water and stay hydrated. No tingling feeling either or signs that it is working unlike other brands. I'm skeptical...

10 out of 10. My go to product for white teeth. Dental professional with over 20 uears experience and won't use anything else.

I was hoping the bristles were a little firmer for getting between my teeth… but it’s making do. I put some of the liquid on my flosser to get deeper. Seems to be working slowly. It’s only been a week and only a slight diff.

Good quality
