Your toothbrush and toothpaste should be some of your best friends as you are supposed to brush your teeth twice a day to help clean your teeth. People have been looking into more natural forms of cleaning and whitening teeth, in efforts to reduce the amount of manmade chemical products used in everyday life. Activated charcoal is found in a lot of beauty products and its use in dental care has been around for ages. People used to clean their teeth with charcoal powder before commercial toothpaste became available.
The supposed benefits of charcoal toothbrushes are:
Reduces tooth staining/increases whitening
Reduces bad breath and odor
The pitfalls of charcoal toothbrushes are:
Not as effective as charcoal paste or powder
Long-term benefits and implications are unknown
These activated charcoal toothbrushes that are recently gaining popularity may be no more than just a marketing hoax for the companies selling them to make money. Many dentists have been saying that these toothbrushes are no different than regular toothbrushes except that they are infused with activated charcoal particles. This is marketed to help remove plaque and stains from the teeth more than normal toothbrushes. There are no studies showing similar or more effectiveness than your regular nylon bristles. Dentists expect that you would loose the activation in the charcoal bristles after a couple uses because after removing the plaque and bacteria from the teeth, and then being rinsed, the brush likely loses its properties.
If you still like the idea of cleaning your teeth with charcoal, you will most likely find better results by using charcoal toothpaste or charcoal powder. It can be assumed that pairing this with the charcoal brush may enhance the benefits, however this is unknown and you will likely just continue receiving the benefits from the toothpaste or power alone.
