Orthodontist vs. Dentist: What's the Difference?
Updated
An orthodontist is a dentist who has completed additional specialist training in moving teeth and aligning jaws, while a general dentist provides routine dental care such as check-ups, fillings, and cleanings. If your concern is mainly about straightening teeth, correcting a bite, or aligning jaws, you generally want an orthodontist; for everyday dental health, a general dentist is the usual starting point. The Association of Orthodontists (Singapore) (AOS) frames this distinction directly on its site with the page "Orthodontist or Dentist?", which signals that the difference matters when deciding who to see.
The core difference
Both roles begin with dental training, but they diverge after that.
- General dentist: Handles the broad scope of dental care — examinations, decay treatment, gum care, crowns, and similar routine needs.
- Orthodontist: A dental specialist who focuses on the position of teeth and the relationship of the jaws. The AOS describes itself as "a professional association representing the orthodontic speciality in Singapore," which reflects that orthodontics is a recognised specialty rather than a general service.
The practical takeaway: an orthodontist is not a different profession from dentistry — it is a specialised branch within it.
When to see which
| Your situation | Reasonable first choice |
|---|---|
| Routine check-up, cleaning, filling, tooth pain | General dentist |
| Crooked or crowded teeth, gaps, bite problems | Orthodontist |
| Unsure whether your case needs specialist care | General dentist, who can refer you |
| Considering a direct-to-consumer aligner product | Read the AOS guidance first (see below) |
A general dentist can often assess whether a case is simple enough to manage in-house or complex enough to refer onward. That referral path is a normal part of dental care, not a sign that something is wrong.
Why the AOS addresses direct-to-consumer products
The AOS site includes a page titled "Why direct-to-consumer products cannot replace orthodontists." This indicates the association's position that mail-order or app-based aligner services are not a substitute for care from a trained orthodontist. If you are weighing a lower-cost remote option against an in-person specialist, that page is the association's own explanation of the limits it sees — worth reading before deciding, since the trade-offs involve supervision, diagnosis, and how complex cases are handled.
How to use the AOS site to decide
The AOS website is organised around two audiences, which makes it easy to navigate by intent:
- For the general public: Pages such as "What is Orthodontics" and "What conditions require orthodontic treatment?" explain the field and the kinds of problems it addresses.
- AOS membership and events: Aimed at professionals rather than patients.
If you are a patient trying to work out whether you need a specialist, start with the public-facing pages. If you are a dental professional looking for the association itself, the membership and events sections are the relevant ones.
A practical way to choose
- Identify your main concern — routine dental health versus tooth alignment or bite.
- If it is alignment or bite, look for a practitioner who is an orthodontic specialist rather than assuming any dentist offers the same scope.
- If you are unsure, book with a general dentist and ask directly whether your case should be referred.
- Before choosing a remote or direct-to-consumer aligner route, read the AOS explanation of what such products cannot replace.
The decision usually comes down to one question: is this a general dental need, or a specialist one? Answering that first makes the choice of practitioner straightforward.
