Looking for a safe and effective way to remove surface stains on your teeth caused by coffee, tea, wine or berries? This activated charcoal toothpaste could be just what you’re looking for!

Activated charcoal is used for its detoxifying abilities. It binds and pulls out toxins and chemicals that are used in beauty products, supplements and even in hospitals where it’s used to treat patients that have been poisoned.  It acts in the same way on your teeth, with tiny pores binding to surface stains. Don’t expect a miracle though, it doesn’t actually “whiten” your teeth, and won’t address deeper damage and staining that occurs from within the tooth.

Because it’s important to know you’re getting activated charcoal that is free from contaminants, we like US sourced products made from coconut shells, like the one below in the recipe.

Activated Charcoal Toothpaste Recipe

I recommend smearing the toothpaste on your teeth (instead of brushing with it) and letting it sit for 5-10 minutes while you go about your morning routine. This way you’ll give the charcoal time to come in contact with, and bind to the stains. Rinse away or gently brush to remove the paste.

Storage & How to Use

Keep out only what you’ll use within 5-7 days and store the rest in the fridge.  The Activated Charcoal Toothpaste is made from real food ingredients and therefore doesn’t contain any preservatives.  Keeping it in the fridge will extend its shelf life, but don’t expect it to last more than a month. Use your senses to determine if you need to toss it and create a fresh batch.  Also, the temperature and humidity of where you live (as well as your bathroom, where you store the paste) will determine how long the toothpaste lasts.

Consider discarding used toothpaste in the trash to avoid clogging sink pipes, as the coconut oil can leave a residue over time.
