Nutrition and oral hygiene

Diet and nutrition are the most important factors affecting the growth and strength of teeth and bones. According to studies and experiments that have been done on various foods and their effects on the teeth, the consumption of some foods increases the likelihood of tooth decay. Therefore, in addition to poor oral hygiene, nutrition can also cause various diseases such as periodontal or other oral diseases.

In general, food can cause tooth decay due to the following factors:

Consistency and strength of food

Foods such as chocolate, which have a high adhesion power, are more likely to cause tooth decay.

The appearance of food

Liquid foods are less likely to cause tooth decay than solid foods in terms of adhesion strength and contact time.

Number of food consumptions

The more times you eat foods that are harmful to your teeth, such as sugar, the more likely you are to have tooth decay.

Ways to prevent tooth decay through nutrition

  • Minimize the consumption of sugary and sweet foods in your diet list.
  • Be sure to brush your teeth after eating foods that are harmful to your teeth, and if you do not have access to a toothbrush, rinse your teeth with water.
  • If you eat foods such as sweets, try to eat with the main meals and not as a snack.
  • Avoid eating very hard foods and fruits.
  • Eat more foods, vegetables and fruits that are good for your mouth and teeth.

Useful food for the mouth and teeth

  • Foods containing vitamin C: such as citrus fruits, dark leafy vegetables, blackberries, cherries, tomatoes, etc.
  • Foods containing vitamin D: such as egg yolks, fish and fish oil, etc.
