GuruNanda Teeth Whitening Pen,(0.06 fl oz)-20 Uses, Vegan & Gentle on Teeth Pro Formula - Hydrogen Peroxide Whitening Gel Pen, Cruelty-Free, Mint Flavor

Brushed this on after nights I drank coffee or tea. The mint gel is easy to point on and didn't leave my teeth sensitive, but stains only looked a little lighter after a couple of weeks, not an instant fix.

I’ve been using the GuruNanda Whitening Pen for a little while now, and I’m genuinely impressed. It’s super easy to apply, doesn’t have a strong or unpleasant taste, and dries quickly so I can get on with my day. After consistent use, I noticed my teeth looking noticeably brighter without causing any sensitivity, which has been an issue for me with other whitening products. The compact design also makes it perfect to keep in my bag for quick touch-ups. Overall, it’s affordable, convenient, and delivers great results. I would definitely recommend it to anyone looking for an easy way to brighten their smile!

I saw many positive reviews, so I decided to give it a try. I've noticed that my teeth have become a little whiter and brighter! It's not messy at all and easy to use after those 15 minutes I brush my teeth for a good 2 mins before rinsing it off. I love this stuff and very affordable willing to purchase more.

⭐⚡⚡UPDATE AGAIN, UPDATE, I do see some difference in the coloring of my teeth. Here is a better picture from March 11th, 2026. I'll have to admit, I wasn't using it everyday, twice a day however, there is some changes in the coloring of my teeth. I think they look whiter and brighter, not so yellow anymore. I'll continue to use this product and do another update in a month. I'M HAPPY WITH THIS PRODUCT. I'M STILL HOPING TO MAKE MY TEETH WHITER- I JUST BOUGHT GuruNanda Teeth Whitening Pen. 20 USES. EXTREMELY AFFORDABLE, SO I BOUGHT TWO. HERE IS A PICTURE OF MY TEETH TAKEN TODAY, 2-28-26. I'll Start using the pen tomorrow and in two weeks I'll be back with another picture of my teeth. WISH ME LUCK 🤞 🤞 Mint flavor. PLEASE READ THE MANUFACTURING INSTRUCTIONS BEFORE USING. 20 USES WITH ONE PEN. BRUSH TEETH WITH YOUR BRAND OF TOOTHPASTE AND TOOTHBRUSH BEFORE USING. I JUST STARTED USING COLGATE OPTIC WHITE TOOTHPASTE THREE WEEKS AGO. SO, ONCE YOU APPLY THIS PRODUCT ON YOUR TEETH, LET IT SIT ON YOUR TEETH FOR 15 MINUTES, THEN RINSE AND GO, AS PER INSTRUCTIONS. IT RECOMMENDS TO WAIT 30 MINUTES BEFORE EATING OR DRINKING. IT SAYS IT'S A CONVENIENT WHITENING AND WORKS QUICKLY AND CAN BE PUT IN YOUR PURSE OR POCKET FOR ON THE GO EASE. I'LL BE BACK IN TWO WEEKS WITH ANOTHER PICTURE OF MY TEETH. 🤞🤞🤞😊

I read other people's reviews so let me start by addressing those concerns. For the taste, 3 out of 5 not horrible, but not great either. It is a mix of peroxide and menthol so yeah, it isn't going to taste like a candy pepermint. Effectiveness: I have had better. It does not work instantly, you have to use it for quite some time to see results (even then, I think it is wishful thinking, tricking people's brains into seeing whiter teeth). But I am giving it the benefit of the doubt, by saying maybe, just maybe after all 20 uses on the applicator, my teeth may be a tiny bit lighter. Use: Use as directed. I have sensitive teeth and the only time I ever felt any discomfort was the 2nd day I used it. No pain just very mild tingle. For those that are screaming chemical burn, just makes it obvious to me, they don't know what a real chemical burn is. A little sensitivity is normal with teeth whitening products. Just because you have sensitivity doesn't mean you got burned. Tip from me, if you have sensitive gums, cover them with a thin layer of vasoline before applying the whitener. I have also found it you take a paper towel and dry your teeth and gums before the application, it says in place better and longer. Saliva is a total killer sometimes when trying a product like this. Value: very good price for the amount of product. My recommendation: Spend a little more to get something more effective; but then, I do like instant results. 2.5 stars for me.

Love that it’s minty but I has excess saliva and didn’t know if I should keep it in so I don’t loose the solution or not (I kept it)lol, for heavily stained teeth u will see changes immediately but for others u would see changes overtime, overall a great product

Easy to Use and Great Results! I’m really impressed with the GuruNanda Teeth Whitening Pen! It’s very easy to apply, dries quickly, and fits perfectly in my bag for touch-ups anytime. After just a few uses, I noticed my teeth looked brighter and my smile felt more confident. It has a pleasant taste and didn’t cause any sensitivity for me. This is a great product at an affordable price, and I would definitely recommend it to anyone looking for an easy way to whiten their teeth at home or on the go.

I use this with a teeth whitening LED/UV gadget from a different product and work amazingly! At the price, you can't go wrong and yes, teeth are whiter and brighter with no issues of sensitivity at all

It is too bad. No effect at all.

It doesn’t do what it claims disappointing
