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

I do feel that this pen has lightened my teeth by a few shades! It’s a straightforward application process and has not caused any sensitivity (something I have experienced with products in the past). I recommend giving it a try if you’re unsure! :)

It applies easily and surprisingly stays in place pretty nicely. There was a nice polished shine on my teeth after the 1st use. I'll continue to buy this brand. I feel like it works faster than crest white strips.

I was a little bit skeptical, but it has pretty good results. Results came within 2-3 uses for me. For the price it’s amazing, it does suck that you only get about 20 uses out of it but because of how little it costs, it’s 100% worth it.

Great product!! It leaves my teeth looking so white after just one use without the burning sensation that some whitening products leave you with. I also have the strips which pairs well if you really want your teeth looking pearly white!!

It works quickly but leaves your teeth sensitive and sore I'm finding it hard to chew a day after using it an dealing in with temperature sensitivity

I know that this tiny whiting pen doesn't seem like much but ohhh boy was I wrong. I went down 1-2 shades in just 30 minutes! This product leaves my teeth feeling like a brand new 100 bucks and boy can't I wait to buy more. I've been on the hunt to find strips, pens, gels all my life and never once have I found a product like this! I only have one complaint... I feel like it should come with a plastic covering because it is a little tricky to keep the gel on your teeth when it mixes in with your saliva. Other than that this product is great!!

I’ve been using the Gurunanda Teeth Whitening Pen almost every evening for about two weeks and I’m already seeing a difference! It’s super easy to apply—just twist, brush it on, and wait a bit before eating or drinking. No mess, no fuss.Even though I don’t drink coffee or tea, I had some mild staining, and this pen has noticeably brightened my smile. Best of all, I haven’t experienced any sensitivity, which is a huge plus.Perfect for daily use or quick touch-ups, and it’s small enough to keep in my bag. Definitely recommend for a brighter smile without the harsh chemicals or expensive treatments!

I loved this Narandu whitening pen/gel. I have pretty white teeth to begin with, but there were some yellow areas closer to the gums I targeted with this. It worked pretty quickly. I initially found this at Dollar Tree, but it was hard to find again. I ordered here on Amazon for not much more than $1.25 and gifted them in stockings for Christmas. I will say it is tough to keep on a full 15 minutes without closing your mouth or talking. Thankfully, I have mouth guards and they helped.
