Mash the berries into a pulp, and add a pinch of sea salt and ½ teaspoon of baking soda, if you’re using it. Wipe any extra saliva off your teeth with a paper towel, and then apply a generous portion of the mixture to a toothbrush and apply. Let the mixture sit for 5 minutes, then rinse. Do this nightly.
3. Coconut Oil Rinse
I know this sounds absolutely mad (I thought it was crazy too when I first read about it) but rinsing your mouth with coconut oil (called ‘oil pulling’) is a unique, old, remedy that people swear by to help whiten teeth. It doesn’t sound like the most pleasant thing in the world, but I actually don’t mind the taste, and I think it does make a difference in the color of your teeth. It won’t make a difference by “bleaching” per say, but lauric acid in coconut oil can rid your teeth of bacteria found in plaque that can make them yellow. It is also supposed to promote gum health, and help keep your breath fresh.
