I'm always trying to find the safest ,and natural products for my family. I did some research on how bad Glycerin is for your teeth. I was determined to find something, that would work for us, and be safe too. I found EarthPaste, and we are in love!! It leaves your teeth feeling like you left the dentist all day. The taste and color are a bit difference from conventional toothpaste, but easy to get use too. I highly recommend this product.
