Hello, I am Ruirui, a nursery nurse. I am happy to answer your questions.

There is an old saying that goes, "Toothache is not a disease, it hurts terribly." Most adults have had the experience of being devastated by teeth, so they pay great attention to the protection of their children's teeth. Nowadays, it is very common for many children to have dental caries, and

Bacterial invasion, eating habits, tooth protection and saliva secretion are related to many factors. Some children can see various oral problems such as black cavities or dental plaque after opening their mouths.

In addition to maintaining children's dental hygiene, pit and fissure sealing is also a very effective protective measure.

Pit and fissure sealing is a method of protecting new permanent teeth recommended by the World Health Organization to children around the world. The Chinese Dental Prevention Organization also recommended this new method of protecting teeth to children across the country.

What is pit and fissure sealant?

Human teeth, especially the back teeth, have some uneven and deep grooves. These are called pits and fissures. Only through the structure of the tooth cusps facing each other can the teeth fully chew and grind food. However, the pits and grooves have small mouths and large bottoms.

, difficult to clean, and can easily accumulate food residues, causing bacteria to breed. Once bacteria invade, they will gradually destroy the entire tooth. Pit and fissure sealing uses dental materials to fill these deep grooves to facilitate children's daily oral cleaning, thereby preventing tooth decay.

role.

Pit and fissure sealing refers to applying pit and fissure sealing materials to the pits and fissures on the occlusal surface and buccal and lingual surfaces of the crown without damaging the dental tissue, forming a protective barrier to cover the pits and fissures.

Prevent cariogenic bacteria and acidic metabolites from eroding teeth, thereby preventing pit and fissure caries.

Why do children need fissure sealing on their teeth?

Most children are in the stage of replacing their deciduous teeth and erupting their permanent teeth, and are at high risk of oral diseases. On the one hand, children are in this special period of teeth replacement, and on the other hand, children generally like to eat sweets, soft foods, and sticky foods, which are easy to eat.

Sticking to the teeth, the effect of children's tooth brushing is generally not very good. The newly erupted permanent teeth are not fully developed, the degree of mineralization of tooth enamel is relatively low, and the resistance to the acidic secretions produced by bacteria is low, which is particularly prone to tooth decay.

What role does fissure sealing of children's teeth play?

Not all teeth need pit and fissure sealing. Which teeth need pit and fissure sealing?

As long as there are teeth with relatively deep pits and fissures, pit and fissure sealing can be performed, and the teeth with deep pits and fissures are usually molars. The deciduous molars that grow when a child is about 3 years old, and the first permanent molars (sixth-year-old teeth) that erupt when a child is about 6 years old.

), the second permanent molars that erupt around the age of 12 can all be treated with pit and fissure sealing. In some children, the bicuspid teeth that erupt around the age of 12 also have deeper pits and fissures, so they can also undergo pit and fissure sealing.

Therefore, it is recommended that parents develop the habit of regular oral examinations for their children, and ask the doctor to determine which teeth of the child have deep pits and fissures, and which ones are suitable for pit and fissure sealing.

Ruirui’s Mom’s Little Classroom: What are six-year-old teeth?

Also called a child's first molar, it is the sixth tooth counting from the first tooth in the center of the front of the mouth. Children usually erupt around the age of 6. The newly erupted sixth teeth have not undergone much wear and tear.

The unworn occlusal surface is uneven, with many deep and shallow pits and fissures, where bacteria and food residues can easily accumulate, making it difficult to clean and prone to caries.

Many parents here often have a misunderstanding. They think that the sixth-year teeth are deciduous teeth and will be replaced when the child grows older. In fact, this is incorrect. In fact, the sixth-year teeth are lifelong and there is no replacement service.

Premature dental caries not only affects the chewing function, but also causes confusion in the bite relationship. In severe cases, it can also affect the child's facial appearance.

When is the best time to perform pit and fissure sealant on your child?

The best time for pit and fissure sealing is when the crown of the tooth has fully erupted and before cavities have occurred.

3-5 years old: deciduous molars 6-8 years old: first permanent molars (sixth instar teeth) 11-13 years old: second permanent molars What is the process of pit and fissure sealing?

Will the child be in pain?

The entire process of pit and fissure sealing is completely painless. Parents don’t have to worry about their children not being able to accept it. Pit and fissure sealing will not damage their children’s teeth, and no anesthesia is required during the entire process. It takes about 6 minutes to complete one tooth, and the entire process is relatively

It is relatively easy and pleasant (provided that the child can cooperate well with the dentist) 1. To clean the tooth surface, install a small conical brush or rubber cup on a low-speed device, dip in an appropriate amount of detergent, and brush the tooth surface and fissures back and forth for about 1 hour

Minutes, while constantly dripping water to keep the brush moist, brush the tooth surface, rinse and rinse your mouth, and then use a sharp probe to remove the detergent remaining in the pits and fissures. The detergent does not contain grease or too fine abrasives. You can use pumice powder or non-containing

Fluoride toothpaste.
