10 Walnut Shell
Take about 30 grams of walnut shells and put them in a pot with water in, on the stove to boil for about 15 minutes. This is also a very odd way to clean tartar from your teeth, but leave your toothbrush in this mixture so that it can soak it up enough so that you can use it to brush your teeth with it. But you have to brush continuously for at least five minutes for the procedure to be most effective at getting rid of that tartar build up.
Try any of these methods with the ingredients available for you. Also, share with others who may think this is useful.
