In general, a patient who does not have a problem with the jaw, and only needs to move the teeth, can see an orthodontist at any age, provided that the gums and jaw bones are healthy. But if it was found during the first examination in childhood that the patient does not suffer from jaw problems and that he has irregular teeth only, then he can see an orthodontist at the age of 10 to 12 years to arrange the teeth. In this age group, because most of the deciduous teeth have fallen out and most of the permanent teeth have grown (with the exception of wisdom teeth and large molars), it is possible to prevent more serious deformities and correct bone and dental abnormalities through an appropriate orthodontic examination.
If these treatments are not done at an appropriate age, they can be done at an older age. After the age of 30, due to decomposition of the jaw bones, the orthodontist must be careful in choosing the type of treatment and method of treatment and provide the patient with complete information about the limitations of the available treatments.
