Crooked teeth resulting in a crooked face can be improved with orthodontics or orthognathic surgery, depending on the cause. Crooked teeth are usually caused by an improper bite, chewing food with one side of the teeth for a long period of time, or bony teeth that are crooked. If the crooked face is caused by incorrect bite, orthodontic treatment can be performed on the teeth, and the symptoms can be greatly improved by wearing braces for a period of time. If the teeth are crooked due to congenital bony causes, the orthodontic operation is less effective and orthognathic surgery is recommended. Depending on the specific situation, there are different ways to correct a crooked face due to crooked teeth. No matter which method, its treatment cycle is relatively long, may need more than one year, usually pay attention to oral hygiene, avoid eating hard things, avoid chewing with one side of the teeth. It is recommended that patients who need to be corrected go to the hospital and follow the professional doctor’s advice to carry out the relevant treatment operations.
