There is a best window for orthodontic treatment, but it is wider than most people assume — and the answer for a child is different from the answer for an adult.
First assessment: age 7 to 9
This sounds early because it is not about starting treatment. At this age a specialist is checking that development is heading in the right direction.
What gets picked up:
- Crossbite — upper teeth biting inside the lower. Far simpler to correct early
- Severe crowding — space can be planned for before it becomes a problem
- Impacted canines — visible only on X-ray, and much easier to guide into place if caught early
- Thumb sucking effects — pushing the upper front teeth forward
- Early loss of a baby tooth, letting neighbours drift into the space
- Jaw growth discrepancies — where the upper and lower jaws are growing out of proportion
Some of these can be intercepted with a simple appliance worn for a few months, avoiding a longer and more complex course later.
Main treatment: age 10 to 14
This is the classic window. Most permanent teeth are through, but the jaws are still growing.
Growth is the advantage. Bone remodels faster in a growing patient, and in some cases jaw growth itself can be guided — an opportunity that closes permanently once growth finishes. After that, the same correction may need surgery.

Adults: any age
Teeth move at 20, 40 and 60. Adult orthodontics is entirely routine now, and a large share of our aligner patients are working adults.
Two differences:
- Bone remodels more slowly, so treatment can run a few months longer
- There is usually more to account for — existing crowns, fillings, missing teeth, and gum condition
Gum health is the real gatekeeper for adults. Moving teeth through bone that is already being lost to periodontal disease accelerates the damage. Any active gum disease must be treated and stable before orthodontics begins. This is not a delaying tactic — it protects the teeth you are trying to straighten.
When to wait
- Active gum disease — treat first
- Untreated decay — fillings first, since brackets cover the tooth surface
- Very early mixed dentition where the problem will resolve itself as teeth erupt
Signs it is time to get assessed
- Teeth overlapping, crowded or noticeably gapped
- Upper and lower teeth do not meet properly when you close
- Jaw clicking, or chewing habitually on one side
- Biting your cheek or the roof of your mouth
- Difficulty cleaning between certain teeth
- Teeth that have shifted since previous braces — relapse
- Simply disliking how your smile looks. That is reason enough
The honest answer
The best time was probably during adolescence. The second best time is now. An assessment costs one appointment and tells you what is actually involved — whether that is starting next month, waiting two years, or being told you do not need treatment at all.
