The child's teeth have fallen out and haven't grown back for a long time.

Why do children’s teeth not grow back for a long time after being extracted? In fact, children's teeth may grow out slowly due to calcium deficiency.

What materials are teeth made of? The main components of teeth are similar to bones, mainly composed of calcium phosphate and calcium carbonate, as well as some other chemical elements, and the surface is hard and wear-resistant enamel. Therefore, we should pay attention to calcium supplementation when teeth are replaced, but due to problems with dietary structure, the calcium intake of Chinese residents is generally insufficient.

How to grow teeth

1. Calcium foods or calcium tablets.

Teeth fall out during the period of tooth replacement. If they do not grow out for a long time, parents should pay attention to whether the child is calcium deficient. They can appropriately increase the intake of foods high in calcium and vitamin D in the daily diet. Foods high in calcium include: dairy products, soy products (tofu), sesame, etc., and foods high in vitamin D include: fatty fish, egg yolks, animal offal, etc. At the same time, take children out to bask in the sun and do some exercise to promote calcium absorption.

2. Pay attention to oral hygiene.

Children should pay special attention to their tooth habits and oral hygiene during the period of tooth replacement, to avoid incorrect tooth habits that may cause uneven teeth or no teeth growing. Paying attention to oral hygiene is mainly to avoid caries during the period of tooth replacement, which may lead to missing teeth. Therefore, parents should pay more attention to their children's oral hygiene, urge them to brush their teeth carefully and let them develop the habit of rinsing their mouths after meals. It is recommended to buy some toothpaste that can prevent tooth decay and replace your toothbrush every three months.

3. Use your teeth to chew food correctly.

When a child just loses a tooth, he always likes to touch the place where the tooth fell with his tongue, or shake the loose tooth that is about to fall out. These may affect the eruption of permanent teeth. Because children are changing their teeth, they like to bite the pen tip because their teeth are itchy. At this time, the teeth are in the development period, which may also affect the growth of teeth and the neat arrangement of teeth. The most important point is to avoid chewing food with the gums for a long time after the teeth fall out, because the gums may become thicker under the action of force, thus hindering the eruption of teeth.

4. Combine coarse and fine foods.

During the period when children are replacing their teeth, parents should ensure that their children have a balanced diet and give them more foods that can exercise their teeth, allow the deciduous teeth to fall out more naturally, and promote the growth and development of teeth, such as: chewing apples, pears, corn, adding celery and coarse grains to regular stir-fried dishes, etc. These chewy foods can not only provide necessary nutrients for children's health, but also promote the eruption of children's teeth.
