The rates of deciduous teeth in 3, 4 and 5 year age groups were 50.8%, 63.6% and 71.9%, respectively. The prevalence of permanent tooth caries was 38.5% in the age group of 12 years. "Young permanent teeth" are more prone to caries, the main reasons include increased food intake containing sucrose, immature tooth morphology and structure, and more prone to caries in the case of incomplete tooth mineralization.

If not properly treated, caries can not only develop pulpitis, apical inflammation, causing severe pain, but also lead to large tooth defects, and ultimately make the tooth impossible to retain.

First of all, the first step we use special equipment to clean the socket thoroughly; The second step is to use an acid etch to treat the surface, and then rinse and dry it after the acid etch; Step three, we apply a sealer.

According to the position of the ditch, we use sealing agent to completely close the place that is not clean. Once it's sealed, we use a photosensitive lamp to re-cure. After curing, it becomes milky white, which is the same color as the teeth, and basically can't be seen.

Whether it is food debris or plaque, it is not easy to deposit in this position, and we are particularly good at cleaning when brushing our teeth, so as to prevent the occurrence of cavities.

A child's tooth is injured or broken

Can I get it back?

Summer vacation is a high incidence of dental trauma in children, mainly including the entire tooth loss or fracture, if these problems should be done? Can the tooth be put back on?

After all, after dislocation, the periodontal membrane cells around the root leave the body for a period of time, at this time, the shorter the interval between putting it back, the better, if replantation can be completed within 30 minutes, the success rate is very high.

For example, the tooth suddenly knocked out, completely knocked off, if it is out, the tooth surface is not particularly dirty, very clean, you can directly according to the position of the tooth, put it back is the best.

Because of the short time, the survival rate is very high.

There is also a possibility that the surface of the tooth will stick to some dust, broken sand, etc., parents should hold the position of the tooth crown, wash it with flowing tap water, wash it clean, and then immediately put it into the alveolus, we call immediate replantation, this effect is very good.

Tooth breakage

Put fresh milk into damaged teeth and seek medical attention

The doctor said that the child's tooth loss can be replanted back, and the broken tooth also has the opportunity to repair, the key is to save the tooth out or broken, as soon as possible to the hospital.

If you can't put the tooth back in time, how should you protect the damaged tooth?

Find a supermarket nearby or there may be fresh milk at home. Put the dislocated tooth in milk. If there is cold milk, it is better to put it in milk and take it to the doctor.

Because when put in milk, the periodontal membrane cells around the root of the tooth can be preserved for a long time, longer than under dry conditions.

When you get to the hospital, you buy valuable time, so that the replantation is easy to succeed.

There is also an emergency method, parents can contain the teeth in their own mouth, because the saliva has a certain buffer effect, but also can make the cells maintain a certain activity.

Protect "young permanent teeth" children brushing teeth "focus"

In daily life, it is very important to protect "young permanent teeth" and brush them well. So, what are the differences between brushing teeth in children and adults? What should I pay attention to?

We still advocate the horizontal flutter brush method, Angle is very critical, the toothbrush should be in place, the bristles and the tooth surface of the jaw are 45 degrees, can be placed between the teeth. The other side is down to the gum. Gently apply pressure.

Lateral vibration, about half the width of a tooth, will clean the teeth between the teeth and the surface of the teeth.

Special places, such as the front teeth must stand up the toothbrush to brush clean, the bite surface can be brushed back and forth, these steps are very critical.
