Improper tooth alignment due to crowding, malocclusion, and missing teeth can cause difficulties with eating and speech, and premature wear. It is estimated that more than 20% of children would benefit from orthodontic treatment to correct these conditions, many of which will persist into adulthood if not corrected. Orthodontic care is gaining popularity among adults for similar concerns, as well as for correction of cosmetic issues. The psychological effects of malocclusion should not be ignored. The American Association of Orthodontists recommends that all children undergo evaluation at the first recognition of an orthodontic condition and no later than age 7 years. Some children will need early treatment to help eliminate developing conditions and improve the foundations of the bite, which can ease later treatment in adolescence. For others, treatment in adolescence without early treatment is recommended. Standard cemented braces or clear, removable aligners may be used, depending on the patient's corrective needs. Average treatment time is approximately 2 years; this may be shortened by the use of accelerative techniques. Routine preventive dental care should be continued during the treatment period.
