Teeth Whitening Pen 4-Pack, Brighten Your Smile in Just 1 Week with Tooth Whitening Pens – Fast, Gentle, Enamel Safe 35% Carbamide Peroxide Whitening Gel for White Teeth in Mess Free Applicator Pens

They worked pretty well I liked it and it served its purpose.

My teeth have a yellowish tint from soda and coffee. I used it twice a day as it stated and I took pictures for my own reference before I started and each day. I could tell a hit of a difference on the 2nd day (after 4 applications- - once in the am, once in the pm) After a week, my teeth were about 6 times whiter. Due to my age and drinking a DP and a cup of coffee on the daily, my teeth never get WHITE WHITE after getting them professionally cleaned. I'd have to have them professionally whitened, but this stuff does a fantastic job. I used it twice a day for 1 month. (1 box is a month's supply) and now I only use it once a day (at night) just to kind of maintain. I also noticed that in the mornings, I don't have that normal crappy, yucky, cotton mouth taste.

First note: I like being able to put it on and forget about it. I don’t feel the need to brush or rinse after.I bought this product because my teeth were becoming too sensitive with the whitening strips. I used it for about a week and it seemed to be helping, or at least maintaining. (I’m a loyal black coffee and red wine drinker) I know it’s one that usually takes a bit longer, and I’m okay with that. It’s easy to apply and the flavor of it isn’t strong at all so that’s perfect. I did get a little on my gum from being too reckless but the pain subsided as normal. Now I use it in the days I don’t want to use the strip. So every 2-3 days I’ll use a crest strip and inbetween I’ll use this product. Definitely will buy again.

It’s ok but i needed something more powerful

ok

I wanted to try this because it is simpler and less messy than white strips. I salivate a lot so I don't like using the strips. I have been diligent in using them as directed. Not as drastic as some of the photos but I didn't expect that since I am an occasional smoker. I use my hair dryer to help dry them faster which also helps me with saliva getting them wet. I will definitely continue to use them and have definitely seen a difference even in the one week or so I've been using them. Of course I forgot to take a photo before I used it the first time so I don't have photos. Would definitely recommend them from my experience so far.

Nothing I disliked!! Was easy to use. I always find something to do while leaving the product on my teeth the correct amount of time because one of my worst qualities is not being patient while having to wait - FOR ANYTING! I knew it was working, but I REALLY knew when my sister told me how white my teeth were. She & I always commiserate about how our periodontal disease is doing since we both have it. She also was amazed that there was no sensitivity to my teeth while using the Pen. Normally we both have sensitivity issues with these types of products, but I had absolutely none with the Soniultra Teeth Whitening Pen!!

This works great i’m already seeing a difference in a week, i only did half of my teeth at first so i could see the color change and people around me even noticed that my teeth were whiter than before. It doesn’t have a flavor so that isn’t a factor which is great so that’s wonderful and it’s simple to use it’s easy and self explanatory you just twist the end of the pen and put it on your top and bottom teeth!! I wish i had found and started using this product earlier in my life it’s a total game changer. i recommend this product to anyone who wants whiter teeth but doesn’t want to buy a overpriced whitening kit that won’t work well.

Easy to use, pretty quick results.Its not even close to a professional kit, but for before a holiday or event if youre on a budget they definitely do a couple shades of whitening. Are you going to get 5-6 shades like at a cosmetic dentist? No. But 2 shades, sure!

I have only been using it for a bit more than a week ans i have noticed a difference. I drink coffee twice a day and diet Pepsi on the weekends so my teeth need some whitening. They are beige color. By applying this product once or twice a day i can see my teeth a shade color whiter. My teeth are sensitive but i did not feel that much sensitivity. I am happy woth this purchase.

This is a wonderful product, it was me and my allergies that caused a problem. I used the pen twice and the inside of my mouth burned for over a week and the skin peeled. I was very careful about not touching my gums when applying. Use a small trial area and wait for results. If you can get past the stinging you willGet beautiful white teeth. I had to quit using.

Did top teeth to compare to bottom over a week once a day.All teeth still same color. Not working for me. But they contacted me to give me a refund since the product didn’t work for me so I appreciate that and have upped my star count.

I bought this product assuming it was like every other teeth whitening products; big promises and little thrill.I was very surprised. I noticed a difference within a week and great improvement with the weeks to come. And the best part, no sensitivity! I always shy away from teeth whitening because of sensitive teeth but this product did not give me any issues.Highly recommend!
