Children with open jaws are generally not self-correcting. Children with baby teeth can be corrected with “lingual braces”. For permanent teeth, they can be treated with fixed braces or invisible braces without brackets. Open jaws in children are caused by genetic factors and bad habits. Genetics is mainly that if parents have open jaws, their children may inherit the characteristics of their parents and develop open jaws. At the same time, some children who are very fond of gnawing fingers, hard objects, etc. during the growth period may develop open jaws. If the child is in the baby tooth stage, you can use the “Tongue Prick Aligner” to block the child’s habit of biting fingers. With the completion of growth and development, many children’s teeth will naturally get better and the open jaw phenomenon will disappear. Many children’s teeth will improve naturally as growth and development is completed, and the open jaw will disappear. Children who have open jaws will not recover on their own, and will need to seek early intervention. If the open jaw occurs during the permanent teeth stage, fixed braces are needed, or invisible braces can be used, which will have some improvement in the treatment of the open jaw, but more serious open jaw symptoms require orthognathic surgery.
