This is easy to use, and my daughter and I each noticed a difference after one use! Your teeth get that really clean feeling, like after a dental cleaning. The charcoal powder, is mildly abrasive, so it really scrubs well. You probably need an electric toothbrush to get the best results. I think you probably reach a max of whitening level, but it still makes your teeth feel amazingly clean. Read more

I love the White Birch Activated White Charcoal Powder! It has significantly brightened my smile after just a few uses. The texture is smooth, making it easy to apply, and it doesn't feel harsh on my teeth. I appreciate the natural ingredients, which give me peace of mind about what I'm using. Overall, a fantastic product that delivers noticeable results. Highly recommend to anyone looking to enhance their dental routine! Read more

This is too minty and burns my mouth. I'm chemically sensitive, so I reached out to this small company to ask if they would offer their white charcoal powder as a separate product several months ago and have received no reply. Mint and other strong flavors are also contraindicated with use of homeopathics. Read more
