Except for whitening the skin, you can also use turmeric powder for whitening your teeth. Here I will describe this video briefly.
Homemade Teeth Whitening Recipe
4 tbsp. of turmeric root powder (organic)
2 tbsp. of baking soda
5 tbsp. of coconut oil (organic).
In a small bowl, add the turmeric powder and baking soda and mix them well. Then add the coconut oil and mash all the ingredients together, using a fork, until you get an orange-thick paste. This paste has no expiry date, but it is better not to use more than 20 uses.
I hope you get what you expect.
