Dental Duty Teeth Whitening Pen (2 Pens), 35% Carbamide Peroxide Gel, 30+Uses, Stain Remover For Beautiful Pearl White Smile, Best Effective Tooth Whitener, Bright Flawless Smile, Natural Mint Flavor.

I am a smoker and wine/coffee drinker. However, I recently quit smoking. I have used pens like these before (surprisingly, much cheaper and from the dollar store). I apply this after brushing my teeth in the mornings with a whitening toothpaste. I usually do my makeup or make a breakfast while I wait for it to work. I think the overall affect of quitting smoking and brushing regularly combined with this would whiten your teeth dramatically, but with time depending on the level of your stains. I’ve noticed a bit of change, but I do drink black teas and coffees and do not use this pen regularly so it is hard to tell. If I developed a habit, I would use this at night. And yes, I did smoke after using this as a customer had asked, but then that just defeats the purpose and slows down the result if any.

I like how convenient these whitening pens are. I like to whiten my teeth in the morning and at night, but I'm not always at home or where I can use a whitening tray. So it was really nice that the package came with 2 pens. I keep one in my work bag and one in my regular bag. The application is so easy and the processing time is so short that I'm able to do it almost anywhere. I brush it on, wait 1 minute, and swish it off with water. I believe it has helped me gain at least a shade brighter. I was going to buy the Kylie whitening pens that are more expensive, but I decide to try these first and I'm glad I did.

Easy to use pens. The pen twists up, allowing one to easily control the amount of product used. It is applied with a brush at the end of the pen, through which the product extrudes. Taste isn’t bad. Whitening is gradual and not with a huge difference after the first use, but there was a bit of difference. After one week of use, noticed a larger difference. No gingival irritation. Can be used daily for maintenance as well. I only used once a day and after a week, there is still product in the pen. Though photos are blurry, perhaps one can see the timeline changes.

These Dental Duty Teeth Whitening Pens are very easy to use with a simple twist and brushing it onto your teeth. They are mint flavored, although I try not to taste them. Easy, simple directions are right on the side of the box. I can feel the minty coolness in my mouth. My teeth have not been sensitive to these at all, which is great because I have had sensitive teeth to some whiteners. I'm not sure if there ARE actually 20 treatments, possibly, maybe more like 16, although I may be applying a little more than necessary. Definitely close, either way. I wipe my teeth off with a tissue first, so there is no moisture getting between the whitening gel and my teeth. I'm seeing improvement and have used almost one pen up so far.

I was very disappointed that there was false advertising in the description of this product. Claim's that product is made in the USA which was a selling feature for me since I'm putting this stuff in my mouth and on my teeth. I wouldn't have trusted product from some 3rd world country. Nothing on the box of this product says Made in USA. It does say that product is distributed out of NJ; however, that means nothing in terms of where product is made. I really hate deceptive companies that do this kind of thing. I ended up using it anyway since I had an event to attend and I needed to whiten my teeth for it. Product did remove a lot of the yellowing stains I had after using 2 times. Otherwise, I would've given 1 star for very misleading info.It's impossible to do both the top and bottom of teeth at the same time without getting your teeth wet (per instructions) so I did the upper's first and then the lowers and that worked out ok. There are other products I could've purchased that cost a little more and are clearly purchased in the USA. That's what I will do next time.

I have sensitivity with my teeth and gums and have tried numerous whitening products! These pens are by far the best whitening product I have purchased! And only $14.99. I spent over $500 at my dentist on the trays and "professional" whitening products and it left my teeth with spots.This pen is amazing! My teeth were yellow a couple weeks ago. You can see them whiten immediately after only 1 use, but with continued use, it is really making a difference. I just saw my dentist today and she asked me if I had been whitening my teeth and thought it was from the dental trays! Nope! don't bother with anything else, these are great!

It did make my teeth whiter, and it was very easy to put on with the brush, but what I realized the difference between the brush and the strips, is that you still have to leave it on for 15 minutes. I had to close my mouth, so I don't know how much of the gel was washed off. The strips keep the gel on my teeth much better.

I’ve tried strips many times and I never keep up with it because it’s such a pain. This pen is super easy to use, tastes like nice mint, and does not hurt my gums (another issue I had with strips.) The results are not as obvious as with other products but I definitely see a difference, especially at my gum line because I don’t mind painting the product there. I like that two pens come in the box so I can really try it long term.
