If a 10-year-old boy’s teeth are bared outward, if it is a dental malocclusion, dental correction should be carried out in time; if it is a bone malocclusion, it can be observed temporarily, and it is better to wait until adulthood for surgical correction. 1. Dental malocclusion: a 10-year-old child’s teeth are bared outward, mainly due to bad biting habits, such as tongue extension, jaw forward, etc. Dental malocclusion is best corrected in a timely manner. It is best to maintain good oral hygiene during orthodontic treatment to avoid the accumulation of food debris on the surface of the teeth, which may cause chronic gingivitis or tooth decay. 2. Bone malocclusion: If your child’s teeth are bared due to bone malocclusion, you can observe them temporarily and wait until your child is an adult to have them surgically corrected. If your child’s teeth are bared at the age of 10, instruct your child to remove the bad oral habits and take him or her to the hospital in time to get a clear picture of the cause of the problem and to have it treated.
