The best time to straighten a child’s buck teeth is usually around the age of 14. This is because at this stage, children have already finished changing their teeth, and orthodontic treatment at this time can make the teeth achieve the ideal straightening effect. If a child has buck teeth, it is generally recommended that the teeth be straightened at around 14 years of age when the permanent teeth have come in. If the teeth are not yet aligned, the teeth will fall out even after orthodontic treatment, so orthodontic treatment is of little significance. And early orthodontic treatment may also affect the loss and growth of teeth. Therefore, it is generally recommended that children should have their buck teeth straightened around the age of 14. Currently, the common methods used to correct buck teeth are metal wire braces and invisible braces, and in the case of bony buck teeth, surgical correction is required. For children who need orthodontic treatment, it is recommended to go to a regular hospital to have their teeth examined by a doctor before orthodontic treatment.
