Public service announcement: You gotta be careful with the charcoal peeps! Doctors have confirmed that activated charcoal can whiten your teeth (yay!) but excessive usage can weaken the enamel of your teeth (boooo!). I recommend you use this toothpaste to whiten your teeth and keep the tube around for when you need it occasionally. Everything in moderation, peeps! Ah yes, and you should also understand that activated charcoal toothpaste is good for surface-level stains made by coffee, wine, dark foods, etc… For deeper stains beneath the surface of your teeth, your best bet is the dentist’s office. Last thing: This toothpaste is vegan, and it’s fluoride-, peroxide-, and gluten-free!
Promising review: “I developed some coffee stains on my two front teeth earlier this summer. I could not get them off with regular brushing and they were making me very self-conscious. I found this product and, after less than a week, the stains are completely gone. Now, I’m going to work on the yellowing of my bottom teeth. Great product!” —Laurapgh
