Ideally, children should be seen for their initial assessment between the ages of 9 and 11 years. This will allow the child's growth and changing dentition to be monitored until all baby teeth have been lost and treatment can begin. Obviously all cases are individual, and some children may start treatment at a younger age. However, you are never too old to start orthodontic treatment, and people of all ages can reap the benefits. Treatment may take a little while longer in adults, but the end result is just as pleasing.
