Children's malocclusion not only affects facial beauty, but also causes chewing disorder and slurred speech, which has great influence on children's physiology and psychology. The following preventive measures can be taken: ① Encourage breastfeeding. Children who can only be artificially fed should lie on their sides, and don't get into the habit of feeding on their backs. 2 Help children to correct bad oral habits. (3) Check with a dentist to see if there is any problem and guide early correction.
Baby expert answers: 1. Parents can use a small wooden board with a length of 10cm, a thickness of 3mm and a width slightly narrower than that of the crossbite incisors, put one end between the inner side of the crossbite upper incisors and the cutting edge of the lower incisors, hold the other end of the wooden board with their hands, and press hard as appropriate to make the small wooden board start to bend. Practice 20-30 times each time, twice every morning and evening, and it usually takes 2-3 weeks to get corrected. If not, you can go to the dentist for orthodontics after four years old.
