Which teeth are most likely to be injured in children

Among children aged 0-6, oral injuries are the second most common injury, accounting for almost 20% of all physical injuries.

There are two peak periods for dental trauma, one is 2-3 years old, and the other is 7-9 years old, both of which are the ages when children love to run and jump.

The most common cause of deciduous tooth trauma is 2-3 years old. The common cause is fall accidents, half of which happen indoors.

This is also true when you think about it. Babies at this age like to run around and like to climb tables and turn cabinets. The baby teeth that grow out are not strong enough, so it is easy to trip over, or fall off the bed or dining chair, which can damage the teeth.

Another peak age is 7-9 years old. Generally, permanent teeth have not grown strong within 3 years after changing teeth, and they are also prone to injury. The most common injury is a broken upper incisor. The most common causes of injuries are falls, car accidents, fights, and sports.

Regardless of whether it is older or younger, boys have a higher frequency of tooth damage.

Children are most likely to fall on the top two front teeth, followed by the two side incisors. Other parts are relatively rare.

Avulsion of permanent teeth is the most serious of all dental injuries, and the first choice of treatment is indeed immediate replantation.


In order to ensure that the permanent tooth can be successfully connected back, the parents should do the following the first time the tooth is knocked out:

1. First of all, find the tooth that fell and pinch the crown of the tooth (note that it is not the root of the tooth);

2. If the permanent teeth are soiled on the ground, don't rub them. Rinse briefly under cold running water for 10 seconds, then put them back in the alveolar, and then let the child bite a clean cotton ball or towel to fix the teeth, and then Go to the emergency room.

3. If the tooth cannot be implanted immediately, it should be stored in a medium that helps maintain the viability of the periodontal ligament fiber cells. For example, soaking in cold milk or saline, it is not enough to hold it under the tongue, or spitting saliva into a cup to soak the teeth in.

But don't soak your teeth in water, because water will cause the osmotic dissolution of periodontal ligament fiber cells.

4. All the above actions must be fast. If the teeth are dry outside the mouth for more than 60 minutes, the root cells will not survive easily.

What examinations need to be done for children with dental trauma

The most basic examination after tooth trauma is X-ray examination, which is a small dental film.

First of all, look at the growth and development of this tooth through a small tooth piece. Although the children are the same age, the tooth age (the degree of tooth development) varies greatly among individuals.

Second, check if the teeth have shifted.

Once again, you can also see if the tooth root is broken. In special cases, you may need to take a CT film.

In addition to the above-mentioned examinations, in clinical practice, doctors also combine a series of examinations, such as pulp vitality test and looseness examination.
