Dentist vs Orthodontist: Key Differences and When to See Each (2026)
You brush, you floss, you visit your dentist twice a year -- but when your dentist mentions that your bite is off or your teeth are crowded, who do you actually see next? The answer depends on understanding the fundamental difference between a general dentist and an orthodontist. While both are licensed dental professionals, their training, expertise, and scope of practice differ significantly. In New York City, where there are over 12,000 general dentists and roughly 1,200 orthodontists, knowing when to see each can save you time, money, and ensure you get the best possible care.
Quick Summary: Dentist vs Orthodontist
- • General dentist: 4 years dental school. Handles all-around dental care: cleanings, fillings, crowns, root canals, extractions
- • Orthodontist: 4 years dental school + 2-3 years orthodontic residency. Specializes exclusively in tooth alignment and bite correction
- • Only ~6% of dentists are orthodontists
- • Both can legally provide Invisalign/braces, but orthodontists have significantly more training in these treatments
- • Orthodontic consultations are typically free in NYC
Education and Training Differences
The single biggest difference between a dentist and an orthodontist is their training. Both start with the same foundation, but an orthodontist goes much further in one specific area.
| Qualification | General Dentist | Orthodontist |
|---|---|---|
| Undergraduate degree | 4 years (Bachelor's) | 4 years (Bachelor's) |
| Dental school | 4 years (DDS or DMD) | 4 years (DDS or DMD) |
| Orthodontic residency | None | 2-3 years (full-time, accredited program) |
| Total years of training | 8 years | 10-11 years |
| Board certification | Optional (ADA general) | Optional but recommended (ABO) |
| Orthodontic cases during training | ~5-10 limited cases in dental school | 300-500+ comprehensive cases in residency |
| Residency acceptance rate | N/A | ~5-10% of dental school graduates |
During their 2-3 year residency, orthodontists focus exclusively on:
- Biomechanics of tooth movement: The physics of how forces from braces and aligners move teeth through bone
- Craniofacial growth and development: How the jaws, skull, and face grow and how to modify that growth in children
- Treatment planning: Analyzing X-rays, 3D scans, and photographs to create comprehensive treatment plans
- Complex case management: Surgical orthodontics, cleft palate cases, impacted teeth, and multidisciplinary treatment
- All appliance systems: Braces (metal, ceramic, lingual), clear aligners, functional appliances, palatal expanders, and temporary anchorage devices
"Think of it this way: every orthodontist is a dentist, but not every dentist is an orthodontist. The additional 2-3 years of residency training is the equivalent of a medical residency -- it is intense, full-time, and focused entirely on tooth movement and bite correction. A general dentist offering Invisalign has typically taken a weekend course; an orthodontist has completed thousands of hours of dedicated training."
What Each Provider Treats
| Service | General Dentist | Orthodontist |
|---|---|---|
| Cleanings and exams | Yes (primary provider) | No |
| Fillings and crowns | Yes | No |
| Root canals | Yes (or refers to endodontist) | No |
| Extractions | Yes (simple extractions) | No (refers to oral surgeon) |
| Braces (all types) | Legally yes, rarely done | Yes (primary provider) |
| Invisalign / clear aligners | Yes (commonly offered) | Yes (primary provider) |
| Bite correction (overbite, underbite) | Limited | Yes (specialized training) |
| Jaw growth modification (children) | No | Yes |
| Surgical orthodontics planning | No | Yes |
| Veneers and cosmetic dentistry | Yes | No |
When You Should See an Orthodontist
The American Association of Orthodontists recommends seeing an orthodontist for:
- Crooked or overlapping teeth: An orthodontist can determine the best approach -- Invisalign, braces, or a combination -- based on the specific type and severity of your crowding.
- Bite problems: Overbites, underbites, open bites, and crossbites require specialized knowledge of how teeth and jaws interact.
- Spacing and gaps: Gap teeth can be closed with orthodontic treatment, often more conservatively than with veneers.
- Children's first evaluation by age 7: An orthodontist can assess jaw growth, eruption patterns, and catch problems early. See our orthodontics for children guide.
- Any time your dentist refers you: If your general dentist suggests orthodontic treatment, a specialist consultation is the logical next step.
- Complex Invisalign cases: If your case involves more than simple crowding or spacing, an orthodontist will generally achieve better results than a general dentist.
Warning: Be cautious of any general dentist who recommends braces or Invisalign for a complex case involving significant bite correction, jaw discrepancies, or surgical planning. These cases require orthodontic specialist training. If your case involves more than straightening mildly crooked teeth, ask for a referral to an orthodontist or seek one out independently.
The Invisalign Question: Dentist or Orthodontist?
Invisalign has blurred the line between dentists and orthodontists more than any other product. Align Technology (Invisalign's parent company) trains and certifies both general dentists and orthodontists to provide the treatment. As of 2025, approximately 60% of Invisalign providers are general dentists and 40% are orthodontists.
So does it matter who provides your Invisalign? Here is the data:
- Complexity matching: Align Technology's own data shows that orthodontists treat significantly more complex cases (Comprehensive and Moderate) than general dentists, who more commonly treat Lite and Express (simpler) cases.
- Refinement rates: Studies suggest that Invisalign cases treated by orthodontists require fewer refinement rounds, indicating better initial treatment planning.
- Complication management: When teeth do not track properly, attachments fall off, or bite issues arise during treatment, an orthodontist has more tools and training to troubleshoot.
- Invisalign tier level: Both dentists and orthodontists are ranked by Align Technology (Bronze, Silver, Gold, Platinum, Diamond). Higher-tier providers treat more cases per year and generally have more experience. Check your provider's tier level.
"For a simple Invisalign case -- minor crowding or a small gap -- a skilled general dentist can deliver excellent results. But the moment a case involves bite correction, significant rotations, or extraction planning, the orthodontist's additional training becomes essential. The challenge is that patients often do not know their case complexity until a specialist evaluates it."

| Metal braces | Rarely offered | $4,500 - $8,000 | Orthodontists only in practice |
| Ceramic braces | Rarely offered | $5,000 - $9,000 | Orthodontists only in practice |
| Initial consultation | $50 - $200 | Free - $250 | Most orthodontists offer free consultations |
How to Find a Good Orthodontist in NYC
New York City has one of the highest concentrations of orthodontists in the country. Here is how to find the right one for your needs:
- Board certification: Look for orthodontists certified by the American Board of Orthodontics (ABO). Board certification is voluntary and requires passing rigorous examinations beyond the residency. Only about 30% of orthodontists are board-certified, and it indicates a higher level of commitment to the specialty.
- Ask your general dentist: Your dentist works with orthodontists regularly and can recommend specialists they trust with their own patients.
- Check Invisalign provider tier: If you want Invisalign specifically, look for providers ranked Gold, Platinum, or Diamond, indicating they treat a high volume of cases annually.
- Read reviews carefully: Google and Yelp reviews from actual patients provide insight into the experience, but focus on patterns rather than individual reviews.
- Consult multiple providers: Most NYC orthodontists offer free consultations. Visit 2-3 before deciding. Compare treatment plans, not just prices.

Questions to Ask at Your Orthodontic Consultation
- • Are you a board-certified orthodontist?
- • How many cases similar to mine have you treated?
- • What is your Invisalign provider tier level?
- • What is the total cost including retainers and refinements?
- • What happens if my treatment does not go as planned?
- • Do you offer 0% interest payment plans?
- • What insurance plans do you accept?
You Still Need a General Dentist During Orthodontic Treatment
An important point: seeing an orthodontist does not replace your general dentist. During braces or Invisalign treatment, you should continue seeing your dentist every 6 months for:
- Professional cleanings: Especially critical with braces, since brackets and wires trap plaque
- Cavity checks: X-rays and exams to catch any decay early
- Gum health monitoring: Orthodontic treatment can exacerbate gum issues if hygiene is poor
- Any dental work needed: Fillings, crowns, or other restorative work that the orthodontist does not provide
Your orthodontist and dentist should communicate about your treatment plan. Most NYC orthodontists will coordinate with your general dentist, especially if dental work needs to be completed before, during, or after orthodontic treatment.
Warning: Do not skip dental cleanings during orthodontic treatment. Patients with braces who skip regular cleanings are at significantly higher risk for cavities and white spot lesions (decalcification marks) around brackets. These marks can be permanent and are one of the most common complications of braces treatment.
Frequently Asked Questions
Legally, yes. Any licensed dentist can provide orthodontic treatment including braces and Invisalign. However, general dentists have not completed the 2 to 3 years of specialized residency training in tooth movement, jaw growth, and bite mechanics that orthodontists undergo. The American Association of Orthodontists recommends seeing a board-certified orthodontist for braces or Invisalign, especially for moderate to complex cases. For simple cases like mild crowding, a well-trained general dentist may deliver good results with Invisalign.
Orthodontists in NYC typically charge $4,500 to $8,500 for Invisalign, while general dentists may charge $3,500 to $7,000. While dentists may appear less expensive, orthodontists generally include more comprehensive treatment planning, better handling of complications, and refinement aligners in their fees. Studies show that orthodontist-supervised Invisalign cases have lower rates of retreatment and fewer complications, which can offset any initial cost savings from going to a general dentist.
You need a general dentist for routine care like cleanings, fillings, crowns, root canals, and gum treatment. You need an orthodontist when you have crooked teeth, a bad bite such as overbite, underbite, or crossbite, spacing issues, or jaw alignment problems. If your dentist suggests you could benefit from braces or Invisalign, ask for a referral to an orthodontist for a specialized evaluation. Most orthodontic consultations are free.
After completing 4 years of dental school to earn a DDS or DMD degree, orthodontists complete an additional 2 to 3 years of full-time residency training exclusively in orthodontics. This residency covers biomechanics of tooth movement, craniofacial growth and development, surgical orthodontics, and advanced treatment planning. Board-certified orthodontists then pass rigorous written and clinical examinations from the American Board of Orthodontics. Only about 6 percent of dentists are orthodontists.
For mild cases like slight crowding or minor spacing, a well-trained general dentist can provide good Invisalign results. For moderate to complex cases involving bite correction, significant crowding, rotated teeth, or extractions, an orthodontist is strongly recommended. Orthodontists treat these cases daily and have the training to handle complications. When in doubt, start with an orthodontist consultation since most are free and provide an expert assessment of your case complexity.
