– It is known that tannin leaves dark stains on teeth
It is known that tannin leaves dark stains on the teeth, and you will prevent it if you put a few drops of milk. The effect, experts say, is better than using whitening toothpaste.
If people that add milk in tea were odd in your opinion, now you might change your mind – writes Daily Mail .
Adding milk in the tea can help to whiten teeth, showed a survey whose results were published in the journal International Journal of Dental Hygiene, and scientists argue that milk is much more effective than toothpaste containing bleach.
It is casein, a protein found in milk. It binds with the tannin in the tea that causes dark spots on the teeth, and the milk prevents their occurrence.
Dr. Ava Chow from the Faculty of Dentistry at the University Albert emphasizes that adding milk in tea is a cultural phenomenon and that this discovery will make people prepare tea in this way.
