5. Sesame seed oil
Ayurvedic medicine is known for using a number of different oils to treat health issues. Oil pulling or swishing oil in your mouth is an age-old technique used by many people to get whiter teeth and improve oral health. While you can use coconut, almond, or olive and still see results, sesame seed oil will work much faster than the others. This process reduces plaque formation, reverses decay, and cures halitosis. Chewing sesame seed before brushing your teeth will also whiten teeth by polishing the surfaces, gradually removing stubborn stains.
