Cause of tooth decay and cavities

    • Lack of calcium, magnesium  and phosphorus rich food
    • Lack of fat soluble vitamins (A, D, E and K, especially vitamin D deficiency)
    • Too much consumption of phytic acid-rich foods
    • Too much consumption of processed sugar

According to the American Dental Association, tooth decay may be prevented by following these four simple rules:

  • Brush twice daily with a fluoride toothpaste
  • Floss daily
  • Have regular professional cleanings and oral examinations.
  • Eat nutritious food and limit sugary snacks

Beside that there are some food to help you fight against cavities & tooth decay

Apples
The prevention of tooth decay can be done through an apple a day. While fresh fruits do contain high sugar levels and can be sweet and acidic, they can stimulate saliva flow, says Reader’s Digest. The extra saliva reduces cavities because it lowers levels of bacteria.

Cheese
Cheese doesn’t contain much sugar, but it does carry protein and calcium – both of which are important for the strength and health of your enamel. As a bonus, the Journal of
General Dentistry recently found eating cheese actively protects the teeth from cavities.

Green and black teas
Tea contains compounds that suppress bacteria, slowing down the processes responsible for tooth decay and gum disease. Depending on the type of water you use to brew your tea, a cup of tea can also be a source of fluoride.

Peanuts
Although both peanuts and peanut butter contain the same fiber, scientists think eating foods that require more chewing is what decreases plaque build-up. Peanuts are one of the least cariogenic (cavity causing) foods you can eat!

Sugarless chewing gum
Chewing sugar-free gum after meals and snacks can help rinse harmful acid off your teeth to help you preserve tooth enamel. Chewing gum containing sugar may actually increase your chances of developing a cavity. Sugarless gum containing xylitol, which has been shown to have decay-preventive qualities, may even have an added benefit.
