When do children's deciduous teeth fall out? When will permanent teeth grow in?

For children, the period of tooth replacement is very important. Because the new permanent teeth will accompany the baby throughout his life and are related to his appearance, eating, and even psychological state. Therefore, care and health care during the period of tooth replacement is very important, especially bad oral habits, which will affect the neatness and beauty.

The impact of retained deciduous teeth falling out

Sequence of deciduous teeth falling out: There is a fixed time and sequence for the deciduous teeth of children to fall out. If the deciduous teeth are not replaced when they should be, it is a delayed state, and the result is usually that the permanent teeth cannot grow in the normal place. Most children start to replace their teeth when they are about five or six years old, and the speed varies from person to person.

Possible problems: Tooth loss usually starts with the two lower front teeth, followed by the two upper front teeth. The most common situation is that the lower front permanent teeth first grow on the inside of the deciduous teeth, and the upper front permanent teeth erupt on the outside of the deciduous teeth, just like double-layer teeth.

Warm reminder: At this time, parents should take their children to the hospital to have the retained deciduous teeth extracted to create an appropriate and correct position for the permanent teeth to come out.

Impact of premature loss of deciduous teeth: If deciduous teeth fall out before they should, it is called premature loss of deciduous teeth. This condition often causes the adjacent teeth on both sides to tilt toward the gap of the missing teeth, making the gap of the missing teeth narrower, so the permanent teeth will grow out of place due to insufficient space.

Treatment and solution: The solution and improvement at this time is to wear a gap maintainer at the gap between the deciduous teeth to prevent the teeth on both sides from being crooked, so that the permanent teeth can remain in the growth area they are supposed to be in until the permanent teeth grow out.

When do permanent teeth erupt?

Normally, children start to change their teeth at around 6 years old. The deciduous teeth begin to fall out physiologically, and the permanent teeth that replace the deciduous teeth erupt one after another. By the age of 12-13, all the deciduous teeth are replaced by permanent teeth. This is the children's tooth replacement period.

Changes in gum thickness: If the baby teeth fall out too early, the child will get used to chewing and licking with the gums, so the gums will become thicker, making it difficult for the permanent teeth to erupt. Therefore, if the baby is at the age of changing teeth, but the permanent teeth have not erupted, it is necessary to take the child to the hospital for diagnosis and treatment of the relevant reasons.

Warm reminder: Calcium deficiency in babies is also an important factor in the late eruption of permanent teeth. Parents should regularly supplement their children with calcium.

Tooth replacement pushes adjacent teeth: During the tooth replacement period, the anterior permanent teeth grow from the bottom or inside of the deciduous teeth. The permanent teeth that grow out are the size of adult teeth. It is normal to have slight squeezing and twisting, which will change and adjust automatically with the growth of adjacent teeth and the development of the jaw.

Correction explanation: As long as the condition is not cross-tooth, it is usually not necessary to correct it, but it should be observed regularly, and the longest time should not exceed half a year. If the teeth are still not aligned properly after all the deciduous teeth have been replaced, you should seek medical treatment immediately to avoid delaying treatment and causing difficulties in correction.

How to care for baby's teeth

The critical period of occlusion: During the tooth replacement period, the deciduous teeth will coexist with the permanent teeth. Because the permanent teeth have just grown out, they are especially important for occlusion. They are larger in size and have more pits and grooves, which are easy to retain food residues. Also, because most children do not clean their teeth thoroughly, they are more likely to have caries problems.

Educate children: The most important thing at this time is to teach children the correct way to brush their teeth. During the period of tooth replacement, when the deciduous teeth are loose and about to fall out, babies like to lick the loose teeth with their tongues. This is a bad habit that will affect the normal growth of permanent teeth. Parents must correct it in time.
