BritenzNatural Teeth Whitening Pen. 05 fl. oz.

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.

This was exactly what I wanted.

I purchased this product in hopes of evening out some discolored spots on my teeth. I used it exactly two times before either the tube mechanism broke or the product ran out. Either way, no gel came out of tube no matter how much I twisted the knob. My money was wasted. Will not be purchasing again.

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