What Is the Difference Between an Orthodontist and a Dentist?
The main difference is scope and training. A general dentist provides a wide range of dental services, from preventive care to restorations. An orthodontist is a specialist who focuses on diagnosing, preventing, and treating misaligned teeth and jaws.
Every orthodontist is a dentist, but not every dentist is an orthodontist. After earning a DDS or DMD degree from dental school, an orthodontist completes an additional 2 to 3 years of full-time residency training accredited by the Commission on Dental Accreditation (CODA). This residency covers biomechanics of tooth movement, facial growth and development, and the design and management of braces, aligners, and other orthodontic appliances.
What a General Dentist Handles
General dentists are your primary dental care providers. They perform routine exams, cleanings, X-rays, fillings, crowns, bridges, extractions, and teeth whitening. They also screen for oral cancer and gum disease. When a dental problem requires specialist-level care, your general dentist typically provides a referral.
- Preventive care: cleanings, fluoride treatments, sealants
- Restorations: fillings, crowns, bridges, veneers
- Basic extractions and root canals
- Teeth whitening and cosmetic bonding
- Oral health screenings and X-rays
What an Orthodontist Handles
Orthodontists focus on tooth and jaw alignment. They diagnose and treat crooked teeth, crowded teeth, gaps between teeth, overbites, underbites, crossbites, and open bites. They plan and manage treatment using braces, clear aligners, palatal expanders, headgear, and retainers.
- Metal braces, ceramic braces, and lingual (behind-the-teeth) braces
- Clear aligner therapy for mild to moderate cases
- Palatal expanders for narrow upper jaws
- Retainers to maintain results after active treatment
- Surgical orthodontics planning for severe jaw misalignment
- Early interceptive treatment for children with developing bite problems
Education and Training: Orthodontist vs Dentist
Both general dentists and orthodontists begin with the same foundation. They complete a four-year undergraduate degree, then four years of dental school earning a Doctor of Dental Surgery (DDS) or Doctor of Medicine in Dentistry (DMD) degree. At this point, their paths diverge.
An orthodontist enters a competitive residency program lasting 2 to 3 years. Only about 6% of dental school graduates are accepted into orthodontic residency programs. During this training, orthodontists treat hundreds of cases under faculty supervision, study craniofacial growth and development, learn biomechanics of tooth movement, and gain hands-on experience with all types of orthodontic appliances.
After residency, orthodontists may pursue board certification through the American Board of Orthodontics (ABO). This involves a written examination and a clinical case presentation. Board certification is voluntary but signals an additional commitment to demonstrated expertise.
When to See an Orthodontist Instead of a Dentist
Some situations clearly call for an orthodontist rather than a general dentist. If your bite is off, your teeth are crowded or spaced, or your jaw does not align properly, an orthodontist has the specialized training to diagnose the issue and plan the right treatment.
See an Orthodontist For
- Moderate to severe crowding, spacing, or rotation of teeth
- Overbite, underbite, crossbite, or open bite correction
- Jaw alignment problems that affect chewing or breathing
- Treatment planning for children ages 7 and up (per American Association of Orthodontists guidelines)
- Cases requiring braces combined with jaw surgery
- Any case where your general dentist recommends a specialist evaluation
A General Dentist May Handle
Some general dentists offer clear aligner treatment for mild cases. If your teeth need only minor straightening and your bite is otherwise healthy, a general dentist with aligner training may be a reasonable option. However, the American Association of Orthodontists recommends that patients with more than mild alignment issues consult an orthodontist.
- Mild crowding or minor spacing with no bite problems
- Minor relapse after previous orthodontic treatment
- Simple cosmetic alignment in the front teeth only
Clear Aligners: Dentist vs Orthodontist
Clear aligners like Invisalign have expanded access to tooth straightening. Many general dentists now offer aligner therapy, and direct-to-consumer aligner companies have entered the market. This raises the question of who should manage your aligner treatment.
For mild alignment issues with no bite problems, a general dentist with proper aligner training can often deliver good results. For moderate to complex cases, an orthodontist brings deeper diagnostic training. Orthodontists are trained to spot bite issues that may not be obvious to a general dentist and to predict how teeth will respond to movement over time.
The American Association of Orthodontists recommends an in-person evaluation by a licensed dentist or orthodontist before starting any aligner treatment. This evaluation should include X-rays and a clinical exam, not just digital photos or impressions taken at home.
Cost: Orthodontist vs Dentist for Braces and Aligners
Orthodontic treatment costs depend on case complexity, treatment type, geographic location, and the provider you choose. In general, treatment from an orthodontist and a general dentist falls within similar price ranges for comparable procedures.
Braces from an orthodontist typically cost $3,000 to $7,000. Clear aligners from either a general dentist or an orthodontist typically cost $3,000 to $8,000. The cost difference between providers for the same treatment is often small. What matters more is the complexity of your case and the experience of the provider managing it.
Most dental insurance plans that include orthodontic benefits cover a portion of treatment, typically up to a lifetime maximum of $1,000 to $2,500. Many orthodontic offices offer payment plans or in-house financing. Costs vary by location, provider, and case complexity.
How to Choose Between a Dentist and an Orthodontist
If you are unsure whether you need a general dentist or an orthodontist, start with your general dentist. They can evaluate your teeth and bite and refer you to an orthodontist if needed. Many orthodontists also offer free or low-cost initial consultations, so you can get a specialist opinion without a large upfront commitment.
When evaluating any provider for orthodontic treatment, ask about their training, how many similar cases they have treated, and what happens if complications arise. An orthodontist's residency training specifically prepares them to manage unexpected tooth movement, root resorption, and other complications that can occur during treatment.
