Not everything our teeth like to eat

Healthy diet is crucial to the condition of our teeth. Not everyone knows what's good for our teeth, what's bad, and why. Here is an overview of foods that strengthen and protect our teeth and about food, which makes them sick. Vegetables such as carrots or celery must be chewed thoroughly. This massages the gums. In addition, the increased salivation cleans the teeth, as well as the interdental spaces and neutralizes large amounts of acids.

Vitamins of all kinds

Numerous vitamins have a positive effect on our dental health:

  • Thus, the vitamin A promotes growth and renewal processes of the oral mucosa. It is abundant in yellow vegetables, green leafy vegetables or fruits.
  • Vitamin C gives power to the immune system and is the parent of dentin. As it is also needed for the collagen formation of the gums, it supports the strength of the teeth. Vitamin C is especially abundant in fresh berries and vegetables.
  • Vitamin D, the "sun vitamin", is responsible for the storage of calcium and phosphate in the bones. It has a beneficial effect on tooth growth and tooth hardening.


They positively affect the mineralization and acid resistance of the teeth. In addition, they reduce plaque formation and inhibit the metabolism of bacteria. It is present in salt, legumes and fish.

Sugar free sweets

Tooth-friendly sweets are characterized by the "tooth man". The sugar has been replaced by sugar substitutes such as aspartame, isomalt, cyclamate, which are not broken down into tooth-damaging acids.


The combination of the protein casein and the minerals calcium and phosphate replaced according to new findings of nutrition science, the minerals of tooth enamel as fast as they were previously dissolved. An acid ph value in the mouth is neutralized by cheese.

Black and green tea

Experts recommend the abundant enjoyment of tea, for example, to combat bad breath. The antibacterial effect - especially of the green tea - deactivates the bacteria in the oral cavity, which cause bad breath. Tea also contains the tannin catechin. This is to intervene in the metabolism of the caries bacterium Streptococcus mutans and makes it virtually starve.


Sugar is the number one toothache. It provides ideal food for caries-promoting bacteria. These bacteria produce acids that attack the enamel. Sugar is present in many foods where it is not suspected, eg. B. in ketchup, ready-made sauces or fruit yogurt.

Acidic drinks and foods

The biggest enemy of the teeth are acids, which dissolve minerals from the tooth surface, thereby changing them and leading to the loss of tooth hard tissue. Such acids either enter the mouth directly through acidic foods or drinks, for example in the form of citrus fruits, fruit juices, cola or vinegar.

Sticky sour food

Particularly bad for the teeth are sticky foods that stay in the oral cavity for a long time, such as dry biscuits, cakes or pretzel sticks. The food literally surrounds the tooth, providing an Eldorado for bacteria. The strong acidity of the vinegar attacks the teeth.
