At what age should my child have an orthodontic check?
An early look at the bite helps you know what's coming. It rarely means treatment needs to start right away.
Many orthodontic groups suggest a first orthodontic check around age seven. By then the first adult molars and front teeth are in, so crowding, crossbites and jaw growth issues are easier to spot. Most children don't need treatment yet. Your family dentist watches the bite at regular checkups and can refer you when it's time.
Why around age seven
At about seven, a child has a mix of baby and adult teeth. The first permanent molars have set the back bite, and the upper and lower front teeth are coming in. This is a useful time to check how the jaws are growing and whether there's room for the remaining adult teeth.
Some problems are simpler to guide while the jaw is still growing. Others are best left until most adult teeth have arrived. An early check helps sort out which is which.
An early look also helps families plan. Knowing that treatment may be suggested in a few years gives you time to check your insurance, ask questions and decide what's right for your child.
Signs worth mentioning to your dentist
- Losing baby teeth much earlier or later than other children
- Crowded, overlapping or widely spaced teeth
- Upper teeth that sit behind the lower teeth when biting
- Front teeth that don't meet when the back teeth are closed
- A jaw that shifts to one side when closing
- Mouth breathing or snoring
- A thumb or finger habit past age four
What happens at the check
The dentist looks at how the teeth meet, counts the adult teeth that have arrived and checks jaw movement. X-rays may be taken if needed to see the teeth still developing under the gums. A digital scan can record the bite to track change over time. At our office, we use an iTero scanner for this.
The visit is short, and most children find it easy. It's mostly looking, counting and talking. Your child doesn't need any special preparation.
Possible next steps
- Watch and wait, with the bite reviewed at each checkup
- Early treatment, such as a space maintainer or expander, through an orthodontist
- Treatment later in the preteen or teen years once more adult teeth are in
- Clear aligners for suitable cases
Braces and aligners
Traditional braces are placed by orthodontists. We do not offer braces at our office, and we can refer you if they're the right fit. We do provide Invisalign clear aligners for suitable patients, including some teens, planned with a digital scan.
Orthodontic treatment is not covered by the Canadian Dental Care Plan. Some private insurance plans include partial orthodontic coverage, so check your benefits booklet.
Frequently asked questions
Does my child need a referral to see an orthodontist?
In Ontario, you can usually book with an orthodontist directly. Many families start with their family dentist, who can tell you if a visit is needed.
Can a seven-year-old get clear aligners?
Some aligner systems are designed for younger children with mixed teeth, but suitability depends on the bite. Your dentist will explain the options.
Is early treatment always better?
No. Many children do well waiting until more adult teeth come in. Early treatment is reserved for specific problems that benefit from it.
Do adults ever need an orthodontic check?
Yes. Adults can have crowding, spacing or bite problems at any age. Clear aligners are one option for many adults, and your dentist can tell you whether you're a candidate.
