Parents are the first person to contact their children and should pay extra attention to the oral hygiene of their children’s newly grown teeth by brushing their teeth on time and rinsing their mouth after meals. Parents should urge their children to brush their teeth and supervise their oral hygiene. In order to strengthen the resistance to tooth decay, you can also let your child brush teeth at home with fluoride toothpaste. Diet: Eating sweet and soft food frequently not only increases the risk of children’s caries, but also is not conducive to the normal development of jawbone. Parents should give children appropriate hard food, the strength stimulation of children in chewing can promote the normal development of jawbone, which is conducive to the normal growth and alignment of teeth. Do not chew on objects that are too hard, as there is a risk of trauma from fractured or cracked teeth. Ensuring a variety of foods during this period can promote the formation of good eating habits and ensure the supply of nutrients needed for growth.
