[German Brand] Premium 30g Activated Charcoal Powder - for White Teeth in a Few Days – 100% Pure - Freshens Breath - Teeth Whitening - Bleaching - Active Carbon Coco Whitener Whiting Tooth Kit

I beat around the bush a lot before finally choosing this activated charcoal brand, I use it in the morning and night by wetting my toothbrush and dipping it in the charcoal slightly. I then brush for 2 minutes. Immediately after you can see whiter teeth and they feel cleaner also.It leaves a lot if mess if you aren't carefulI though there'd be a terrible taste and smell to it, but it's actually fine.

Was using for few days very messy stoped to use after few days

This Charcoal for teeth whitening, I mixed with organic coconut oil as well and brush my teethIt's works very good.
