Dentist or Orthodontist? The Two-Minute Sorting Guide

Every orthodontist is a dentist; almost no dentists are orthodontists. That asymmetry — and the rise of general dentists offering aligners — is why the question matters more than it used to.

The training difference

A general dentist finishes dental school and can legally perform nearly any dental procedure, including orthodontics. An orthodontist adds a competitive 2–3 year residency doing nothing but tooth movement and jaw growth — thousands of supervised cases before their first solo one. The specialty exists because moving teeth safely through bone, managing roots, and timing growth in kids is its own discipline.

Who handles what

Dentist: cleanings and exams, fillings, crowns and bridges, root canals, extractions, gum care, whitening — the health and repair of teeth.

Orthodontist: braces and aligners, bite correction (over-, under-, crossbites), jaw-growth guidance in children, impacted-tooth traction, retainers — the position of teeth and jaws.

The overlap zone is mild-crowding aligner cases, which many general dentists now treat. For genuinely mild cases that’s often fine; the honest line is that a bite problem, a deep overbite, rotations, or anything in a growing child belongs with the specialist — not because dentists are careless, but because case selection is itself the specialist skill.

Practical rules

• Kids get an orthodontic evaluation around age 7 (most need nothing yet; the few who need early intervention need it found).
• You don’t need a referral to book an orthodontist, and consults are commonly free.
• Keep seeing your dentist during orthodontics — braces make hygiene harder exactly when it matters most.
• For adult aligner treatment offered at a general practice, one free orthodontist consult is the world’s cheapest second opinion. If both say “mild case, either path works,” pick on convenience and price with a clear conscience.
