How to make teeth whiter

　　Want your teeth to be as white as snow? In fact, it’s very simple, just eat more of the following 10 foods in your daily life!

　　1. Sugar-free chewing gum

　　It can increase saliva secretion, neutralize acidity in the mouth, and further prevent tooth decay.

　　2. Water

　　Drinking moderate amounts of water can keep your gums moist and stimulate saliva production. Drink water after eating to take away the food residue left in the mouth, preventing bacteria from getting nutrients and taking the opportunity to cause trouble and damage the teeth.

　　3. Mint

　　Mint leaves contain monoterpene compounds, which can reach the lungs through blood circulation and make you feel fresh when breathing.
