Lavadent - 1 fl. oz.

Easy to use and it works! Perfect for whitening teeth naturally.would be better in spray form. As pure and safe as it can be.

This product does work, however, the result does not make my teeth as white as other non-holistic products, which I am fine with. The adventage is I don't need to stop drinking tea or coffee while using the product, but the disadventage or inconvenience is I am supposed to brush my teeth with this product after each meal. What I am doing now is instead of "after each meal", I only use it after I drank tea or coffee.The other thing I don't like about this product is the dropper bottle. It simply doesn't work, because while I was instructed to shake the bottle before use, drops (two or three) of this product will be dripping from the dropper cap into the sink or spilling down the side of the bottle as I open the bottle. If i tried to put on my toothbrush, more drops will drip into the sink, if I tried to put in my mouth directly, drops will ended up on my face. Given that this product is not cheap, every drop that didn't get use is money down the drain. Mind you, the instruction says you need 15 drops each time, when I was using 15 drops 3 times a day, plus the wastage, the bottle lasted me about 2 weeks. Now I that I have attained a whiter color, I only use 5 drops each time as maintenance (not including the drops that got wasted), my bottle can last over a month.I would like to see the company change the dropper bottle to like an eye drop bottle which will make so much more sense.
