When should kids get braces?

Every parent who notices crooked teeth in their 8-year-old assumes treatment should start now. Sometimes they're right. Often they're not. Here's how to think about timing.

Age 7: the screening visit

By age 7, the first permanent molars and incisors are usually in. This gives an orthodontist enough information to spot problems that need early intervention, and to confidently say come back in 3 years for the cases that don't.

The screening visit is a 20-minute look at how the bite is developing. There's no obligation to start anything. The point is to catch the rare problems that actually benefit from early treatment, and to reassure you for everything else.

Phase 1 (ages 7–10): when early treatment helps

About 1 in 5 kids actually benefit from early intervention. The specific problems where early treatment makes a difference:

• Crossbite (top teeth biting inside the bottom teeth), easier to fix while the jaw is still growing
• Severe crowding with no space for permanent teeth coming in
• Protruding upper teeth that are at high risk of trauma
• Thumb-sucking or tongue-thrust habits that are deforming the bite
• Underbite caused by the lower jaw outgrowing the upper
• Significant breathing issues related to a narrow upper jaw

If your child has any of these, early treatment for 6–12 months can prevent much bigger problems later. Often it eliminates the need for tooth extractions in their teens.

Phase 2 (ages 11–14): the standard window

This is when most full orthodontic treatment happens. By 11–13, almost all permanent teeth are in. The jaw still has growth left, which makes some movements easier. Compliance is generally good, kids at this age are old enough to look after their own oral hygiene.

Treatment in this window typically takes 18–24 months for a comprehensive case. After that, retainers (worn at night) keep things stable through the teenage growth spurt and into adulthood.

Why earlier isn't always better

It's tempting to think let's just get it done now. But starting too early often means:

• Kids end up in two rounds of treatment instead of one, ultimately more time in braces
• Teeth move into a temporary position that has to be redone after the rest of the permanent teeth come in
• More wear on enamel from longer cumulative treatment time
• Compliance fatigue, by the time the real treatment starts in their teens, they're tired of dental visits

If a clinic recommends braces for a 7-year-old without identifying one of the specific problems above, get a second opinion.

What to actually do as a parent

1. Around age 7, book a free orthodontic screening. Just to know.
2. If everything looks normal, the orthodontist will tell you when to come back, usually around age 11.
3. If early treatment is recommended, ask exactly which problem it solves and what would happen if you waited. A good orthodontist will explain clearly.
4. Don't compare your child to other children's timelines: every kid's mouth develops at a different pace.

What about adults reading this for themselves?

Read our adult braces post. Short version: there's no upper age limit. About a third of our patients are over 30. Outcomes are excellent.
