Six-year-old tooth is the first permanent molar, named after the average eruption age is six years old. Six-year-old teeth are very important for children's maxillofacial development. Its position in dentition and its own health will have a certain impact on other teeth. If it is lost early, the second permanent molar can move forward obliquely, resulting in uneven tooth arrangement. Six-year-old teeth also play an important role in chewing If they are lost early, alveolar bone will be highly underdeveloped, which may lead to malocclusion of anterior teeth. Six-year-old teeth are permanent and will not be replaced for life. Take good care of them. Besides brushing teeth carefully, fluoride and pit and fissure sealant can also be selected under the guidance of dentists to prevent dental caries.

Pit and fissure sealant The chewing surfaces of bicuspids and molars are uneven and there are some natural pits and fissures. Plaque is easy to accumulate in these parts and cannot be removed by brushing teeth or other mechanical methods, so the incidence of pit and fissure caries is high. Dentists can use pit and fissure sealant to seal these pits and fissures to prevent the accumulation of dental plaque, thus effectively preventing pit and fissure caries.

Adolescent gingivitis Adolescent gingivitis occurs among teenagers. The main manifestations are that the interdental papilla on the lip side of the anterior teeth is spherical, the gums are congested and swollen, red and shiny, and it is easy to bleed when brushing teeth or biting food.

Therefore, we should pay special attention to correct brushing and flossing to control dental plaque, ask doctors to clean and remove teeth and stones, and pay attention to a balanced diet to maintain the health of bone tissue and gums.

School-age children with tooth trauma have a lot of exercise and are prone to tooth trauma. There are many kinds of tooth injuries, including fracture, fissure, displacement and dislocation.

If trauma causes teeth to completely come out of the mouth, put the fallen teeth in a glass of water or milk or wrap them with a wet towel, or put them under the tongue and take the children to the hospital for treatment. Dentists can fill teeth. If you can get to the hospital within 30 minutes, the long-term effect of replantation is very good. Under normal circumstances, replanted teeth can function normally for several years.
