Children's orthodontic assessments from age 7
The right time to check isn't always the right time to treat. A first orthodontic assessment around age seven can identify bite or tooth-development concerns while your child is still growing — and help you make a clear plan for what happens next.
Why should my child see an orthodontist at seven?
Around age seven, many children have a mixture of baby teeth and permanent teeth. Their first adult molars and front teeth may already be present. This gives a specialist orthodontist a useful opportunity to assess how the teeth and jaws are developing — before all the adult teeth have erupted.
See how the jaws fit together
Identify crossbites, a bite that shifts to one side, or an emerging underbite tendency.
Check the path of adult teeth
Look for early signs of teeth erupting in the wrong position, loss of space or developing crowding.
Decide when to act
Some problems may benefit from intervention during growth; others are best reviewed and treated later.
An orthodontic assessment at seven does not mean braces at seven. For many children, the most appropriate recommendation is to monitor growth and review the bite as permanent teeth emerge.
When might an earlier orthodontic assessment help?
You do not need to diagnose an orthodontic problem yourself. If you notice any of the following, ask your dentist or an orthodontist for advice.
- Front or back teeth biting the wrong way round (a crossbite)
- The lower jaw shifting sideways when your child closes their teeth
- Lower front teeth biting in front of the upper front teeth (an underbite)
- Very prominent upper front teeth, particularly where there is a risk of injury
- Adult teeth erupting unusually, or baby teeth lost much earlier or later than expected
- Marked crowding, loss of space, or persistent habits affecting the bite
These signs do not automatically mean treatment is necessary. Each child needs an individual clinical assessment.
What happens after your child's first check?
At Newpark, we aim to recommend treatment only when its expected benefits justify starting it at that stage of development.
1. Everything is developing well
We explain what we see and advise whether another check is needed in future.
2. Growth monitoring
We review tooth eruption and changes in the bite. Treatment may be more appropriate later.
3. Selective early treatment
If a particular issue is better addressed now, we discuss the available options, benefits, limitations and timing.
What are Phase 1 and Phase 2 orthodontics?
Phase 1: early or interceptive treatment
When indicated, a focused period of treatment while some baby teeth remain. Depending on the problem, the plan might involve expansion, correcting a crossbite, managing space, or other carefully selected treatment.
The aim: address a specific developing problem at an appropriate time — not simply straighten every tooth early.
Phase 2: treatment after more adult teeth erupt
Some children later benefit from a further course of braces or aligners to refine alignment and the final bite. Other children do not need a second phase.
The aim: finish the bite and alignment once tooth eruption and growth make that appropriate.
Two phases are not automatically better than one. Starting treatment early does not guarantee that teenage braces, extractions or other procedures can be avoided.
How do we treat children at Newpark Orthodontics?
We provide specialist orthodontic care at Newpark Clinic on Newtownpark Avenue in Blackrock, South Dublin. Dr. Máirlín O'Donnell has over 20 years' experience in orthodontics and assesses children's developing teeth and bites as well as treating teenagers and adults.
Listen and examine
We discuss your concerns and review facial growth, tooth eruption, jaw relationships and how the bite functions.
Explain the options
Where treatment is appropriate, we explain the alternatives. These may include fixed or removable appliances, expanders or clear aligners where clinically suitable.
Plan the follow-up
You will know whether to start, monitor or return later, and why. Scans or radiographs are arranged only if needed for diagnosis or planning.
Frequently asked questions
You do not need to diagnose an orthodontic problem yourself. If you notice any of the following, ask your dentist or an orthodontist for advice.
Does my seven-year-old need braces?
Usually, a first visit is an assessment rather than the start of treatment. Many children are simply monitored until more permanent teeth have erupted. Treatment is recommended only if there is a clear reason to act sooner.
Should we wait until all the baby teeth have fallen out?
Not necessarily. Some bite or eruption problems are best assessed while baby teeth remain. Having a check around seven helps establish whether waiting is safe or whether early intervention could be useful.
What is interceptive orthodontic treatment?
Interceptive or Phase 1 treatment is focused orthodontic care during the mixed-dentition years, often around ages 7–10. It addresses a selected problem, such as certain crossbites or eruption concerns, rather than aiming to complete every aspect of orthodontic treatment.
Will Phase 1 mean my child avoids braces as a teenager?
Not necessarily. Some children still need Phase 2 treatment when their adult teeth erupt. We discuss that possibility before recommending early treatment.
Can children have clear aligners?
For selected children, clear aligners designed for mixed dentition can be an option. Whether they are suitable depends on the bite, the movements needed and how reliably the child can wear them. Other appliances may be more appropriate.
What if my child’s bite looks normal?
Subtle concerns are not always obvious at home. An assessment can provide reassurance and a sensible timetable for future reviews, even if no treatment is required.
Do we need a referral from our family dentist?
You can contact our team directly to enquire about an orthodontic assessment. We also welcome referrals from family dentists and communicate with them as part of your child’s ongoing dental care.
