Primary teeth begin to space out to make room for permanent teeth at about age 6. Orthodontic problems can be apparent from the age of 7 when the first permanent incisors grow in. At that age, if necessary, a simple treatment such as a space maintainer may be indicated. However, it is sometimes preferable to wait until age 10 before initiating more advanced treatment. Dental and skeletal growth mostly takes place between the ages of 7 and 12. Hence, the prevention of space loss for permanent teeth can be achieved in particular through expansion, space maintenance, or rehabilitation.
