Kids Orthodontist: 5 Signs Your Child May Need an Evaluation

When should your child see an orthodontist? Learn the five signs that deserve attention and why an early evaluation does not necessarily mean braces right away.

Por Dra. Camila, Cirurgiã-Dentista September, 2026.

If you’ve ever looked at your child’s smile and wondered, “Is this normal, or should I have it checked?”, you’re definitely not alone.

As a mom and a pediatric dentist, I know how easy it is to worry when you notice a tooth coming in crooked, a bite that doesn’t seem to fit quite right, or a baby tooth that falls out much earlier than expected.

The good news is that an orthodontic evaluation does not automatically mean your child needs braces.

Sometimes, the best thing an orthodontist can do is simply monitor your child’s growth and tooth development.

So, how do you know when it’s time to make that first appointment?

Let’s look at the signs worth paying attention to.

Kids orthodontist: when should your child see an orthodontist?

There isn’t one perfect age for every child to begin orthodontic treatment.

Every child develops differently, and the right timing depends on their teeth, bite, jaw growth, and overall development.

The American Association of Orthodontists recommends that children have their first orthodontic checkup by age 7.

And this is something I really want parents to know:

A checkup at age 7 does not mean your child is going to get braces at age 7.

The purpose of an early evaluation is to identify potential problems while there is still time to monitor growth and, when necessary, guide development.

In some cases, no treatment is needed at all.

5 Signs Your Child May Need an Orthodontic Evaluation

1. Your child’s teeth look very crowded or crooked

Some baby teeth naturally look a little uneven, and that doesn’t necessarily mean the permanent teeth will have the same problem.

However, significant crowding, overlapping teeth, or very little space for permanent teeth to erupt are good reasons to have your child’s smile evaluated.

An orthodontist can look at how the teeth are developing and determine whether there is enough space for the permanent teeth.

Sometimes, simply keeping an eye on development is all that’s needed.

2. Your child’s bite doesn’t seem to fit properly

Take a look when your child bites down.

Do the upper and lower teeth come together comfortably?

Problems with the way the teeth fit together can include:

• Crossbite — some upper teeth bite inside the lower teeth
• Open bite — some teeth don’t meet when the mouth is closed
• Deep bite — the upper front teeth cover too much of the lower teeth
• Underbite — the lower teeth sit in front of the upper teeth

These bite differences don’t always require immediate treatment, but they are worth discussing with a dental professional.

Early evaluation can help determine whether monitoring or treatment would be beneficial.

3. A permanent tooth is taking a long time to come in

Have you noticed that one tooth seems to be taking much longer to appear than the others?

Sometimes a permanent tooth may have trouble erupting because there isn’t enough room or because it is developing in an unusual position.

This is another situation where an evaluation can be helpful.

The earlier the situation is understood, the more options the dental team may have for managing it.

4. Your child still has a strong oral habit

Thumb sucking and prolonged pacifier use are common during infancy and early childhood.

But when a sucking habit continues for a long time, especially with frequent or intense sucking, it can affect the developing bite and the position of the teeth.

The impact depends on several factors, including:

• how often the habit occurs
• how long it continues
• how intensely the child sucks
• the child’s age and stage of development

If you’re concerned about a thumb-sucking or pacifier habit, talk with your child’s pediatric dentist or orthodontist rather than trying to force the habit to stop overnight.

Gentle guidance usually works better than pressure.

5. Your child lost a baby tooth much earlier than expected

Baby teeth aren’t just temporary little placeholders.

They help children chew, speak, and maintain space for permanent teeth.

When a baby tooth is lost too early, neighboring teeth can sometimes shift into the space that the permanent tooth will eventually need.

Depending on the situation, a dentist or orthodontist may recommend monitoring or a space maintainer to help preserve that space.

That’s why it’s a good idea to mention early tooth loss during your child’s dental visit.

My child is 7. Do they need braces?

Not necessarily.

This is one of the biggest misconceptions about the recommendation for an orthodontic evaluation around age 7.

The goal is not to put every 7-year-old in braces.

At this age, an orthodontist can evaluate how the permanent teeth are coming in, how the upper and lower jaws are developing, and whether there are signs of a problem that may need attention.

For some children, treatment may be appropriate during this stage.

For others, the orthodontist may simply recommend monitoring their growth and checking again later.

Both are perfectly normal outcomes.

What is the best age for braces?

There isn’t one magic age when every child should get braces.

Some children benefit from treatment while they still have a combination of baby and permanent teeth.

Others are better treated later, when more permanent teeth have erupted.

The right timing depends on the specific orthodontic problem and your child’s stage of development.

That’s why I prefer talking about the right time for your child, rather than giving parents a single age and telling them that’s when treatment should begin.

What types of orthodontic treatment are used for kids?

Depending on the child’s needs, an orthodontist may recommend different types of treatment.

These can include:

• Removable orthodontic appliances
• Palatal expanders
• Space maintainers
• Traditional braces
• Clear aligners in selected cases

There isn’t one appliance that is best for every child.

The treatment should be chosen based on the child’s teeth, bite, growth, and specific orthodontic needs.

Can mouth breathing be related to orthodontic problems?

Sometimes, but mouth breathing does not automatically mean a child needs orthodontic treatment.

Children may breathe through their mouths for several different reasons, including nasal congestion, allergies, enlarged tonsils or adenoids, and other airway-related concerns.

Because of this, persistent mouth breathing deserves a proper evaluation rather than simply being labeled an orthodontic problem.

Depending on the situation, your child’s pediatrician, pediatric dentist, or orthodontist may be part of that evaluation.

What happens during a child’s first orthodontic evaluation?

The first appointment is usually much simpler than parents imagine.

The orthodontist may look at:

• How the teeth are positioned
• How permanent teeth are erupting
• Available space
• The way the upper and lower teeth fit together
• Jaw growth and facial development
• Oral habits
• Functional concerns

X-rays, photographs, or other records may be recommended when they are clinically appropriate.

And sometimes the conclusion is simply:

“Everything looks good. Let’s keep monitoring.”

Honestly, that’s a wonderful answer to receive.

How can parents help their child’s orthodontic development?

You don’t need to become an orthodontic detective at home.

Just pay attention to changes.

Notice when baby teeth are lost, how permanent teeth are coming in, whether your child has persistent oral habits, and whether they seem to have difficulty biting or chewing.

And keep regular dental appointments.

Your child’s pediatric dentist can often identify changes during routine visits and let you know when an orthodontic evaluation would be helpful.

When should you take your child to an orthodontist?

If your child is around age 7 and has never had an orthodontic evaluation, it’s reasonable to schedule one.

And if your child is younger but you have a specific concern—such as a significant bite problem, a tooth that isn’t erupting normally, early loss of a baby tooth, or a persistent oral habit—you don’t necessarily have to wait until age 7.

An earlier evaluation may be appropriate depending on the situation.

The important thing is not to panic.

An evaluation is simply a way to understand what is happening and what, if anything, needs to be done.

Kids orthodontist: the most important thing is knowing when to evaluate

When it comes to children’s teeth, timing really does matter—but that doesn’t mean we need to rush into treatment.

Sometimes the best orthodontic plan is to treat.

Sometimes it’s to monitor.

And sometimes it’s simply to reassure a parent that everything is developing normally.

As a mom, I know how much peace of mind that reassurance can bring.

Your child’s smile doesn’t need to be perfect at age 7.

It just needs the right attention at the right time.
