Yes, we know that tumeric powder is used as a way to make (or stain) things yellow. However, the rhizomatous herbaceous perennial plant of the ginger family, from which turmeric powder belongs to, is great for whitening teeth. Another reason to consider using the powder, is because it has positive effects against gingival inflammation. To use this method, simply take your toothbrush, wet it, and dip it into a 1/8 teaspoon of turmeric powder. After your brush your teeth with the powder, you let it sit on your teeth for at least 3 to 5 minutes. Once the time has passed, clean your mouth out with water, rinse thoroughly and spit it out. You may need to repeat this process in order to remove leftover turmeric powder around the edges of your teeth. You can also mix 1/4 teaspoon of turmeric powder with 1/8 teaspoon of melted coconut oil. Make a toothpaste using both ingredients and brush your teeth with it; just like if you were doing it with regular toothpaste. Allow to sit for 3 to 5 minutes and clean thoroughly just like the other methods.
