Teeth Whitening Pen, Use Twice a Day Up to 1-6 Shade Whiter in 1-2 Weeks, 4 No Sensitivity Pens, 70+ Whitening Treatments, Effective, Pain Free and Enamel Safe, Easy to Use at Home Travel, Flavourless

Love these. Super easy and noticeable change.

I've used these a few times now (not long term, to be fair - just a few days in a row) and don't see any results. But they also don't cause any teeth sensitivity and they are very compact + easy to use, so there is potential for whitening effects to show up after more time. Personally, I see much quicker, more noticeable results with Meijer brand whitening strips for just a few dollars more. However, you get more uses out of this whitening pen pack, so it's a great value if it happens to work for you or if you're a bit more patient.

I have a very sensitive nose and smelled Clorox type smell while applying this to my teeth which scared me but either way, it pretty much whitened my teeth before my eyes! I forgot to take pictures but I had darkness between my teeth and I focused the product there and it worked miracles! Where White strips couldn’t reach this product did! I would recommend to everyone. Only give the product a four-star because I’m not sure if it contains some type of Clorox type ingredient.

I had previously used the 5 - Minute Whitening Gel and it was ok over time, about 8 weeks. But this whitening pen showed results right after the first use. Before I used it, I held a square of white toilet paper to my teeth. After I twisted the bottom to release the gel, I applied a thin layer to each tooth and held my smile for :30 seconds, as instructed. After 30 minutes, I gargled and was amazed at how much whiter my teeth were. What I would like is if the instructions were written on a piece of paper along with the tooth color guide found inside the box. I had to turn the box over and sideways to find the instructions. Also, the Amazon description says more than on the box. It's not clear on or in the box as to how many uses are available for each of the 4 pens. And also, that it's safe for daily use. All in all? Worth the $12.

Terrible taste— and directions say not to get it on your gums. That’s nearly impossible since it needs to stay on your teeth for about a half hour.

I'm using this product for the first time ever due to years of drinking tea daily. The pen brush an twist to get gel into the brush end makes for easy application to my teeth. I brush first wait a few minutes dry teeth with tissue open pen twist gel into brush an apply whitening gel hold gums off top teeth for 30 second an repeat application to bottom teeth again holding lips off teeth for 30 seconds. I then put in clear liners 15 minutes after application. Im doing this process 2 times a day which is recommended by the manufacturer. It's only been a few days but am noticing a bit of a difference in whitening. I will wait for at least a week or two to provide more details but appears to be promising. I don't notice any gum or side affects or adverse flavor in my mouth after applying the gel.

It’s just liquid I thought it was gel. I returned them

These PamBoo teeth whitening pens are great! I was pretty skeptical because I have the expensive custom made trays from my dentist. I don’t like using them because they make my gums AND my teeth hurt. Before using the PamBoo pens I put a little Vaseline on my gums just in case. I applied the gel and I could actually see the coffee stains coming off. I did take a cotton round and fold it and then folded it again and put it between my front teeth to remind myself to keep smiling slightly for 30 minutes. I did this because I didn’t want to risk getting the gel on my gums. Then I did some busy work so the 30 minutes would go by quickly. The results were better than I expected and I’ll be doing a treatment for the next week. Be sure to take a before picture so you can see how it’s working. I’m a happy camper. A+++
