Your dentist says your child may need braces, or perhaps you are an adult wondering whether clear aligners could fix crowded teeth. The next step may be a referral to an orthodontist—but what does an orthodontist do that a general dentist does not?
An orthodontist is a dentist with advanced specialty training in diagnosing, preventing and treating problems involving the alignment of the teeth and jaws. These specialists do more than straighten smiles. They help create a stable, functional bite so the upper and lower teeth meet properly, making everyday activities such as biting, chewing and speaking more comfortable and efficient.
What Does an Orthodontist Do for Patients?
Orthodontists evaluate how the teeth, jaws and facial structures work together. They treat malocclusions, commonly called “bad bites,” including overbites, underbites, crossbites and open bites. They also manage crowded teeth, excessive spacing, protruding teeth and teeth that have not erupted in the expected position.
Treatment begins with a detailed assessment. Depending on the patient’s needs, an orthodontist may examine the mouth and face, review dental and medical history, take photographs, request X-rays and create digital scans or impressions of the teeth. These records help the orthodontist see tooth roots, jaw relationships and developing teeth that are not visible during a routine examination.
The orthodontist then develops an individualized treatment plan. Common responsibilities include:
- Diagnosing tooth and jaw alignment problems
- Planning how and when teeth should move
- Applying and adjusting traditional or ceramic braces
- Prescribing and monitoring clear aligners
- Using expanders or other appliances to guide jaw development
- Creating space for permanent teeth to erupt
- Monitoring facial and dental growth in children
- Prescribing retainers and checking long-term stability
- Coordinating complex treatment with dentists, oral surgeons and other specialists
Orthodontic treatment is not limited to children and teenagers. Adults can also receive braces, aligners and other forms of treatment. The best approach depends on the condition of the teeth and gums, the type of alignment problem and the patient’s goals.
Why Bite Alignment Matters in Everyday Life
A straighter smile may be the most noticeable result of treatment, but appearance is only part of an orthodontist’s work. The purpose is to create a healthy bite in which opposing teeth meet appropriately. According to the American Dental Association’s overview of orthodontics, a good bite can make it easier to bite, chew and speak.
Alignment problems can affect people differently. A patient may have difficulty biting into certain foods, experience uneven tooth wear or feel self-conscious about visible crowding or spacing. Crowded or overlapping teeth may also be more challenging to brush and floss thoroughly.
Orthodontists consider these functional and practical concerns when recommending care. They also monitor oral health throughout treatment because braces and other appliances can trap food and plaque. Patients still need regular dental checkups and must follow brushing, flossing and appliance-care instructions carefully.
Orthodontist Versus General Dentist
All orthodontists are dentists, but not all dentists are orthodontists. A general dentist provides broad oral healthcare, including examinations, cleanings, fillings, gum care and treatment for damaged or decayed teeth. Some general dentists also offer limited orthodontic services.
An orthodontist has completed additional full-time education focused specifically on tooth movement, jaw alignment, facial growth and bite correction. Orthodontists generally limit their practices to this specialty rather than providing routine cleanings or restorative procedures.
The two professionals often work together. A dentist may identify a developing bite problem and refer the patient for an orthodontic evaluation. During orthodontic treatment, the general dentist continues to monitor the health of the teeth and gums. Patients may also be referred to periodontists, oral surgeons or other specialists when a case requires coordinated care.
What Treatments Do Orthodontists Provide?
Braces
Fixed braces use brackets and wires to apply controlled pressure to the teeth. The orthodontist adjusts the appliance over time, gradually guiding the teeth into planned positions. Braces may be metal or made with less noticeable ceramic materials.
Clear Aligners
Clear aligners are removable trays made to move teeth through a planned series of stages. They are not appropriate for every patient or every type of bite problem. An orthodontist determines whether aligners can achieve predictable results and monitors progress throughout treatment.
Growth-Guidance Appliances
Children whose jaws are still developing may benefit from expanders or other orthodontic appliances. These devices can address certain width, spacing or jaw-development concerns at an appropriate stage of growth. Early evaluation does not always mean immediate treatment; sometimes the orthodontist simply monitors development until the timing is right.
Retainers
Teeth can shift after braces or aligners are completed. Orthodontists prescribe retainers to help hold the teeth in their new positions. Long-term retainer use is often an essential part of protecting the result.
Care Involving Jaw Surgery
Severe skeletal differences may not be correctable with tooth movement alone. In these cases, an orthodontist may work with an oral and maxillofacial surgeon. The orthodontist typically aligns the teeth before surgery and refines the bite afterward.
Education and Training Required
Becoming an orthodontist requires a lengthy educational path. Students usually complete undergraduate coursework that includes sciences such as biology and chemistry before applying to dental school. Dental school generally takes four years and leads to a Doctor of Dental Surgery, or DDS, or Doctor of Dental Medicine, or DMD, degree. The degrees have equivalent educational standing.
After dental school, an aspiring orthodontist must be accepted into an accredited orthodontics and dentofacial orthopedics residency. Most programs take two or three years and include classroom instruction, research and extensive supervised clinical experience. Residents study subjects such as biomechanics, facial growth, radiographic diagnosis and treatment planning.
Orthodontists must meet dental licensing requirements in the state where they practice. Some jurisdictions have additional requirements for specialty practice. Board certification is another credential an orthodontist may pursue, but it is voluntary and is separate from basic state licensure.
What Is an Orthodontist’s Career Like?
Most orthodontists work in specialty dental offices. Some own a private practice, join a group practice or work as associates. Others pursue careers in dental schools, research, public health, hospitals or the military.
A typical day may include new-patient consultations, treatment-planning appointments, appliance placement, progress checks, emergency repairs and discussions with parents or other healthcare professionals. The work combines healthcare, technology, detailed hand skills and long-term relationship building. Because treatment often lasts many months, orthodontists regularly follow patients through important stages of development and change.
The career requires patience, precise visual judgment, communication skills and the ability to explain complex plans in reassuring language. Practice owners also need business and leadership skills. Students comparing different options may find it useful to explore other healthcare careers supported by medical technology education before committing to a lengthy professional degree.
When Should Someone See an Orthodontist?
A dentist may recommend an orthodontic evaluation after noticing crowding, unusual tooth eruption or an abnormal bite. Patients can also schedule a consultation if they are concerned about spacing, protruding teeth, difficulty chewing or changes in how their teeth meet.
An evaluation does not guarantee that treatment is necessary. The orthodontist may recommend beginning soon, waiting while growth continues or taking no action beyond routine monitoring. Ultimately, what an orthodontist does is combine dental science, careful planning and ongoing supervision to improve how the teeth and jaws fit and function—not simply how a smile looks.
