I was skeptical at first but this charcoal powder really does work! I have noticed a difference after about a week. The flavor is mint so it doesn’t taste bad when using it and there is no unpleasant after taste. The powder is very fine so there is not gritty residue like you would think. Of course it doesn’t look pretty when you are using it but it works and that’s what matters! It is made of 100% organic coconut charcoal made from coconut shells so you don’t have any weird ingredients that you are unsure about. It’s really simple to use. You just get your toothbrush wet put some of the charcoal powder on your brush and brush gently for 3-5 minutes. After that you just rinse and you are done. The container says to dip it in the charcoal which is up to you, I personally use a little scoop and scoop some of the powder and put it on my toothbrush. It is suggested to use this twice a day. So you can simply add it to your morning and night routine when you are brushing your teeth. The only thing is you need to be careful when using it because it can stain different surfaces like fabric, counter tops, and clothes. Just make sure to protect your counter top and the clothing you are wearing when you use it. Again it is 100% natural and organic so it is completely safe to use.
