Tooth decay (caries): Its natural remedies

Tooth decay (caries)

Tooth decay is the process that results in a cavity (dental caries). It occurs when bacteria in your mouth make acids that eat away at a tooth, if not treated, tooth decay can cause pain, infection, and tooth loss.

Four main things that contribute to tooth decay:

  1. Lack of minerals in the diet (calcium deficiency, magnesium deficiency, and phosphorus deficiency)
  2. Lack of fat-soluble vitamins (A, D, E and K, especially vitamin D deficiency)
  3. Too much consumption of phytic acid-rich foods
  4. Too much consumption of processed sugar
You can easily prevent tooth decay by brushing and flossing your teeth regularly, seeing your dentist for teeth cleaning and checkups, and avoiding foods that are high in sugar.

The combination of bacteria and food causes tooth decay. A clear, sticky substance called plaque that contains bacteria is always forming on your teeth and gums. As the bacteria feed on the sugars in the food you eat, they make acids. The acids attack the teeth for 20 minutes or more after eating. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay.
