Cheese
Cheese is rich in calcium, which helps neutralize acids in the mouth after meals. Cheese also increases the production of saliva - the mouth's natural defense system.
crispy fruits and vegetables
The crunchiness of fruits and vegetables helps remove plaque on teeth and the high water content helps increase saliva circulation. Some crispy fruits and vegetables that you can add to your diet include apples, carrots and celery.
Green leafy vegetables
Spinach, kale and other green vegetables are rich in calcium, folic acid and important vitamins that help strengthen teeth and gums.
Nuts
Nuts such as almonds, walnuts and cashews are low in sugar and rich in minerals. Chewing these nuts also stimulates saliva secretion, which helps control harmful bacteria. Choose unsalted and unsweetened nuts.
Green tea and black tea
Green tea and black tea contain polyphenols that help fight bacteria and reduce acid levels in the mouth. These teas also help reduce plaque buildup. Just rinse your mouth with water after drinking tea to avoid yellowing.
