Dentist vs. Orthodontist: What's the Difference?

If you’ve ever wondered whether you need to see a dentist or an orthodontist for a specific issue, you’re not alone. It’s one of the most common questions we get from new patients — and honestly, the answer isn’t always obvious.

Both are dental professionals. Both went through years of specialized training. Both care about your oral health. But they do different things, and knowing which one to see (and when) can save you time, money, and a lot of confusion. Here’s a simple breakdown.

Here’s a simple breakdown:

The Short Version

A dentist takes care of your overall oral health — your teeth, gums, and mouth in general. An orthodontist is a dentist who specialized further and focuses specifically on tooth alignment, bite issues, and jaw development.

Think of it this way: every orthodontist is a dentist, but not every dentist is an orthodontist.

What Does a Dentist Do?

Your general dentist is your first line of defense for everyday oral health. They handle the day-to-day care that keeps your teeth and gums in good shape. Most people see their dentist every six months for a routine cleaning and checkup.

Things a dentist typically handles:

• Cleanings and preventive care
• Cavities and fillings
• Crowns, bridges, and dental implants
• Root canals
• Tooth extractions (sometimes referred to an oral surgeon)
• Gum health and periodontal treatments
• Whitening and cosmetic bonding
• Diagnosing oral health issues

Your dentist is also the one who often notices when something needs a specialist’s attention — including when it might be time to see an orthodontist.

What Does an Orthodontist Do?

An orthodontist is a dentist who completed an additional 2-3 years of specialized training after dental school, focused entirely on how teeth and jaws move, grow, and align. This extra training is what makes orthodontists uniquely qualified to plan and manage tooth movement.

Things an orthodontist typically handles:

• Braces (metal, ceramic, and other types)
• Invisalign® and other clear aligners
• Bite correction (overbite, underbite, crossbite, open bite)
• Crowding and spacing issues
• Early treatment for kids with developing bite or jaw issues
• Palate expanders and other growth-friendly appliances
• Retainers and post-treatment care
• Craniofacial and complex jaw cases

Because moving teeth is a nuanced, long-term process, orthodontists develop deep expertise in things like how much force is safe, how fast teeth should move, and how to coordinate care with other specialists when needed.

So Who Do You See for What?

Here’s a quick guide to help you know where to start:

See your dentist for:

• Regular cleanings and checkups
• A toothache or sensitivity
• A cavity or broken filling
• Bleeding gums
• A cracked or chipped tooth
• Bad breath that won’t go away
• Whitening or cosmetic questions

See an orthodontist for:

• Crooked or crowded teeth
• Gaps between teeth
• Bite issues (top and bottom teeth don’t fit together right)
• A child around age 7 for a first orthodontic evaluation
• Jaw pain that might be related to alignment
• Interest in Invisalign or braces
• A retainer that’s lost, broken, or no longer fits

If you’re not sure which one you need, start with your regular dentist — they’ll point you in the right direction if a specialist is needed.

Do You Need a Referral to See an Orthodontist?

Nope. You can book directly with an orthodontist without a referral from your dentist. Many patients come to us on their own — either because they’ve been thinking about treatment for a while, they’ve noticed changes in their smile, or they want an opinion for their child.

Your first consultation with us is complimentary. We’ll take a look, talk through your goals, and let you know if treatment is a good fit — no pressure either way.

How Dentists and Orthodontists Work Together

Here’s something patients don’t always realize: your dentist and orthodontist are on the same team. We work closely together throughout your treatment to make sure everything is going smoothly.

For example:

• You still see your regular dentist every six months for cleanings during orthodontic treatment
• If your dentist notices a cavity, we may pause certain movements while it gets treated
• Your dentist can share x-rays and records with us to avoid duplicate scans
• We can update your dentist on your progress and any concerns

If your treatment plan involves other specialists — like an oral surgeon, periodontist, or ENT — we help coordinate that too. The goal is a smooth, connected experience for you.

What About Kids? When Do They See Which?

For most kids, the timeline looks like this:

• Their first dental visit happens around age 1 or when the first tooth comes in
• They see their dentist every 6 months for cleanings and checkups
• Around age 7, they see an orthodontist for a first evaluation

That first orthodontic evaluation doesn’t mean treatment is starting — most kids don’t need braces that young. We just want to catch any bite or jaw development issues early so we can monitor them or intervene if needed. For more on when kids should be evaluated, take a look at our post on signs your child may need early orthodontic treatment.

Can My Dentist Just Do My Braces?

Some general dentists do offer orthodontic services, and legally they’re allowed to. Whether that’s the right choice comes down to how complex your case is and how comfortable you feel with someone who does orthodontics part-time versus a specialist who does it every day.

Simple cosmetic cases can sometimes be handled by a dentist. But for anything involving bite correction, complex movements, growing kids, or long-term stability, seeing a board-certified orthodontist is usually the safer bet. Our post on how to choose the best orthodontist has more on what to look for.

The Bottom Line

Your dentist and your orthodontist both play important roles in your oral health. Keep seeing your dentist regularly for cleanings and everyday care, and lean on an orthodontist when it’s time to think about alignment, bite, or your kid’s developing smile.
