Orthodontics is a specialized field of dentistry focused on correcting the alignment of teeth and jaws, most commonly associated with braces. The goal of this treatment is to improve bite function, oral health, and smile aesthetics by moving teeth into proper positions. Determining the optimal time to begin treatment is a frequent question, as jaw development and the presence of permanent teeth change throughout life. This article explores the life stages when orthodontic treatment or a preparatory assessment is most beneficial.
The Recommended Age for Initial Orthodontic Assessment
The American Association of Orthodontists (AAO) suggests that every child should have their first check-up with an orthodontist no later than age seven. At this age, a child typically has a mix of baby and permanent teeth, providing a clear window into their developing bite structure. The first permanent molars have usually erupted by age seven, which helps the specialist evaluate the back-to-front and side-to-side relationship of the jaws, known as the posterior occlusion.
This early assessment does not mean treatment begins immediately; often, the orthodontist monitors the child’s growth and dental development. The evaluation allows for the early detection of subtle problems like severe crowding, crossbites, or harmful habits that could impact future development. If an issue is identified, a specialist may recommend “Phase I,” or interceptive, treatment to address a specific problem while the jaw is still growing, potentially simplifying or shortening later comprehensive treatment.
The Peak Time for Comprehensive Treatment
The period of adolescence, generally between the ages of 10 and 14, is considered the most effective time for comprehensive orthodontic treatment using full braces. This window is ideal because most permanent teeth have erupted, and the body is experiencing its major pubertal growth spurt. The surge in growth during these years makes the jawbones and surrounding tissues less dense and more pliable than in adulthood.
This increased biological responsiveness allows the orthodontist to harness the body’s natural growth to correct significant jaw discrepancies, such as overbites or underbites. Full treatment often involves applying braces to both upper and lower dental arches to fine-tune the alignment of every tooth. For most adolescent patients, this comprehensive phase lasts for about 18 to 24 months.
Common Indicators That Treatment Is Necessary
The need for orthodontic treatment is defined by the presence of a malocclusion, or “bad bite,” which can manifest in several ways. One common indicator is crowding, where insufficient space in the dental arch causes teeth to overlap, twist, or appear crooked. Crowded teeth make proper brushing and flossing difficult, increasing the risk of cavities and gum disease.
The following are common indicators that treatment is necessary:
- Spacing: Noticeable gaps exist between teeth, often due to a mismatch between the size of the teeth and the size of the jaw.
- Overbite: Occurs when the upper front teeth significantly overlap the lower front teeth. An excessive overbite can lead to abnormal wear on the lower teeth and potential jaw joint strain.
- Underbite: Present when the lower front teeth protrude past the upper front teeth, creating a reverse overlap. This misalignment can cause an unbalanced facial profile and lead to difficulties with chewing and speaking.
- Crossbite: A condition where one or more of the upper teeth sit inside the lower teeth when biting down, which can happen in the front or back of the mouth.
Considerations for Adult Orthodontics
Orthodontic treatment is not exclusive to children and adolescents, with a significant number of adults seeking care to correct long-standing issues or relapses from prior treatment. The main biological difference in adult treatment is that the jawbones are fully developed and no longer growing, making them denser and less flexible. This means tooth movement can be slightly slower, potentially extending the overall treatment duration compared to an adolescent case.
Adult patients often present with existing dental work, such as crowns, bridges, or fillings, and may have underlying gum health issues that require management. These factors necessitate careful planning and coordination between the orthodontist and a general dentist. Many adults prefer more discreet treatment options, such as clear aligners or ceramic braces, which minimize the visual impact of the appliance.
