Charcoal whitening powder for a brighter smile
on September 27, 2017
This teeth whitening powder has worked for me. My teeth are already pretty white to begin with but this definitely brightens them up. It's also really easy to use. Just dip your toothbrush into the powder, brush, and then rinse. There isn't a noticeable taste during or after using, either. I've used it a couple of times a day for about a week and I still have almost a full container.
