Natural Teeth Whitening Pen, 05 fl. oz. (Pack of 2)

I have used various whiteners in the past and thought Britenz is a bit more pricey than some, the convenience of the pen brush and the fact that it REALLY WORKS are worth it.

I did buy the same product from Whole Foods and I liked it so much so ordered a 2nd one from Amazon but the one I received it tastes so weird and gross, I would not recommend it. I wonder if it is expired the package was unopened and sealed but I dir not pay attention to expiration dates and threw away the box came in.

This product works!! The directions are a little vague stating “leave gel on for as long as desired” I leave the gel on for about 15-20 minutes but I do end up swallowing most of it by that time anyway lol. I will say the taste is gross but it’s better than any other teeth whitening strips I’ve used. I did see some comments stating they couldn’t get any gel out of the pen. The directions state you may have to twist the pen a few times the first use… I twisted that pen like 78 times. The gel did come out! It did come out! And now I only have to twist it twice or after that initial use. So all and all interesting experience but I have to give it 4 stars because it works and it’s not bad ingredients!

When I received the product it had spilled inside the cap. The company said they were going to replace it. So far, no go. The instructions say 2 weeks max. The product only lasted less than one week. The small amount of whitening effect seen was reversed slightly every time I would eat or drink again. Would like to see what a whole 14 days 2X per day would really show. The tube would not even bring the product to the surface as if there was none in the tube.

As the title says, Britenz tastes & works just like Crest & other well-known whitening brushes with the added benefits of xylitol and aloe. Just a shame about the lack of product in the tube: I got 2 total uses out of it and only applied it on my front 15 teeth! Not only that, I just apply it near the base of the teeth where the most discoloration is. I kept the lid on between applications & stored it in a cool, dark location so it definitely didn't evaporate or anything. I tried turning and turning (and turning) the tube but no luck. It truly was empty after only 2 uses several months apart.Maybe it was a defective unit, maybe not. If not I'd advise the makers of Britenz to either lower the price dramatically & start labeling these as "samples" or put more product in their tubes because it's a quality product aside from that. My teeth do look visibly whiter after using.

I put this inside my retainers at night and my teeth be white in the morning!

I have used this product for a couple years. When you turn the dial at the bottom of the tube a gel comes up into the little brush normally. This time a liquid poured out and down the tube and it had a funny taste I threw it away. Won’t buy again.

I've been using this for about a week now and haven't noticed any results. It might take a while, which is fine. I think part of the problem is that the gel probably wipes off some when I let my lip back down to cover my teeth (after applying). It's too bad this isn't more like the old Crest Night Effects (which I can't find anymore) which "dried" a few seconds after brushing it on.I'm still rating it 4 stars because of the application method. I grind my teeth at night, so I've worn them down so that the nerve is exposed on the biting surfaces. For this reason, I can't wear strips or trays. Strips and trays put the gel right on the nerve and after a few uses, I'm in excruciating pain. With this product, I can brush it directly on the front surfaces of my teeth, avoiding the biting surfaces (and lots of pain). With any other bleaching product, I would be in agony right now (even after only a week)...and I have zero pain so far.So, even if it takes longer to get a result, I'm OK with that since I'm avoiding the pain.
