Why do new teeth not grow for a year when they are replaced?

Generally speaking, children will have all their teeth replaced by around the age of thirteen. During the process, some teeth grow earlier and some grow later. If there is a situation where no new teeth grow for a year during the period of tooth replacement, it is best to go to the hospital for relevant examinations. After finding out the cause, symptomatic treatment should be given. When children are replacing their teeth, it is important to maintain oral hygiene, let them brush their teeth correctly, and give them appropriate calcium supplements.

When does children start to change their teeth?

Children usually start to lose their teeth around the age of 6. The physiological shedding of the first deciduous tooth usually occurs around the age of 6, but it can also occur as early as 4 years old, or as late as 7-8 years old, so there is no need to worry. Naturally fallen deciduous teeth have no roots and the fallen surface appears eroded. Parents should pay attention to observe and not confuse them with broken roots of deciduous teeth.

People grow teeth twice in their life, namely deciduous teeth and permanent teeth. There are 20 deciduous teeth, which usually start to erupt around 6 months old and are fully grown at 2-3 years old. There are 28-32 permanent teeth (the number of wisdom teeth is 0-4), which usually start to grow around 6 years old and 28 are fully grown at 12-13 years old (wisdom teeth vary from person to person). Therefore, the tooth replacement period is usually between 6 and 12 years old. There are certain rules for tooth replacement. Simply put, it is a certain time and a certain order, following the principle of "left-right symmetry, first lower and then upper". Left-right symmetry, first lower and then upper refers to teeth with the same name.

Generally speaking, children's teeth change in a symmetrical manner, with the upper and lower rows of teeth changing first and then the lower ones. The order in which children replace their teeth is:

(1) When children are 6-8 years old, they begin to grow their first permanent teeth, the central incisors, and the first molars also gradually grow out;

(2) When children reach 8-9 years old, lateral incisors begin to grow;

(3) Children aged 10-12 years old begin to grow bicuspids, starting with the first bicuspids, which are next to the lateral teeth;

(4) When children are 11-12 years old, the upper and lower canines have gradually grown out;

(5) Children aged 12-13 begin to grow second molars;

(6) The last third molar, also known as the wisdom tooth, does not begin to grow until the child is 17 years old, and will continue to grow until the age of 21, which varies from person to person.

Is it good for children to change their teeth too early?

Premature tooth replacement is usually caused by trauma to the child's teeth, such as tooth bumps; it may also be caused by certain oral diseases, such as tooth inflammation, caries, etc. Gingivitis is relatively common among children, but it is very rare for periodontal disease to cause tooth bone damage, so mothers need to know the causes of premature loss of deciduous teeth in order to protect the remaining deciduous teeth. Because it lays a good foundation for the normal growth of permanent teeth. Early diagnosis helps doctors take effective measures to ensure that permanent teeth can erupt and align normally.

Therefore, parents must be vigilant about their children's tooth replacement time and observe their dental conditions diligently. If you find that your child's deciduous teeth fall out prematurely due to caries, trauma, periodontal disease, etc., you should seek medical attention as soon as possible to avoid damage to the bite function and affect the normal development of permanent teeth and maxillofacial area.
