Why rub charcoal on your teeth? It mostly just sounds gross.
Activated charcoal is actually not charcoal, even though it looks and obviously sounds like it. Activated Charcoal is typically made from coconut shells, bamboo, olive pits, and other plant based materials. The mixture is heated, which oxidizes and activates it. Hence, "Activated Charcoal". When this material is activated, it becomes much more porous, which makes it better able to capture and absorb plaque and bacteria, rather than just spreading it around.
It's not surprising that the use of charcoal in healthcare procedures is nothing new. The first recorded medical use in the United States was in 1834. A doctors used activated charcoal to cleanse a patient that had consumed mercury chloride, ultimately saving the patient's life. The use of charcoal for healing practices, in the Asian culture, date back much much further.
The manufacturing process gives Activated Charcoal its powerful absorption capabilities, it's highly porous consistency allows it to attract and absorb harmful bacteria from the mouth as well as chlorine and particles from tap water, which is why Charcoal is so often used as a natural water filter. Known as 'adsorption', this process allows chemicals to bind to the exterior of the Charcoal so they can be removed from the body. Through its antibacterial, anti-fungal and antiviral properties, Activated Charcoal may also help to avoid bad breath. In a powder form, Activated Charcoal is amazing at removing plaque, stains and build up on the teeth, helping to lift coffee, tea and wine stains to leave teeth sparkling clean and white, with its whitening power increased even more when used with a Charcoal toothpaste.
Charcoal toothbrushes have many of the same benefits as charcoal toothpaste. Here are some of the main benefits:
Activated charcoal properties built into the bristles, so there’s no need for messy charcoal powder
Absorbs plaque and bacteria rather than rubbing it across the teeth
Helps whiten teeth
Fights teeth stains left by things like coffee and red wine
Can help reduce bad breath
