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

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.

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.

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.

It works! My wife wanted it for some whitening, she can't use straps because of sensitivity. This pen not only works but she can avoid the sensitive teeth.

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.

Really works to brighten teeth quickly!

This works remarkably well. I could see a result immediately after applying it to my teeth. Subsequent applications have not been so dramatic, but my teeth look better everyday. I've only been using for 3 or 4 days so ther should still be lots of improvement. I drink a lot of tea so that is my major source of staining. I would definitely recommend and I will buy again. I have very sensitive gums and I've had no problems so far.
