Understanding Craniofacial Development in Children

Little Boy and Little Girl are Smilig

It is our absolute passion to help kids sleep, breathe, and thrive. We believe in early intervention and follow the latest research to support craniofacial development in children. Because we’ve been treating adults and seeing the negative impact on their oral health due to an underdeveloped craniofacial structure, it has become our mission to assist the younger generation in preventing such issues. Our doctors are so passionate about this subject as they also have children.

There are several symptoms that are highly correlated with the underdevelopment of the jaw structure, including snoring, grinding, bedwetting, night terrors, ADHD, anxiety, TMJ issues, headaches, and speech problems. We used to see these symptoms mainly in adults, but now we see them in kids, too.

The next few minutes I’m going to talk about cranial facial development of children. And this child came to me because dad was worried that the pediatric dentists wanted to take out her baby teeth sequentially to allow the adult teeth to come in and then eventually take out her adult bicuspids. And something that didn’t sit right with her dad, and partly because he went through the same thing when he was, who was younger and then now suffering through sleep apnea. So he didn’t want this to happen to his child. So we discussed our options here and maybe there are times when it makes sense, but nowadays, knowing what we know, we would never want to take out any adult teeth if we can avoid it. So what we did for her was to expand her. So we expanded her palate to be much, much larger to allow one all the teeth to be in, and second is all the T to be in, but without crowding. So that’s always our primary goal.

And as you can see, this is a very different trajectory. I think the benefit not only not only has aesthetic benefits, but also has health benefits because we’ve been doing this for a while now. We’ve seen other kids that went through the expansion process where parents reported to us that the kids now don’t get up at night. They used to less bedwetting or no bedwetting afterwards, used to have asthma, but now it’s weaning off asthma medications, behaviorally and academically all improving. So there’s just so much benefit of making more room for breathing and sleep. And if you kind of go back to this picture where you see crowding, teeth crowding really is just a sign of under development. So whenever we have a chance to actually deal with the child to be wider, where all the teeth will come in, this is really a normal development. So we hope this video can help you. If you’re a parent watching this and you have questions about any of this, please do reach out to us. We’re very happy to talk to you about just different ways to help your child. Well, thank you and thank you for watching, and hopefully this is helpful. Thank you.

The problem may originate from soft tissues, such as enlarged adenoids/tonsils, tongue ties, or improper oral muscle function. If left unaddressed, symptoms may worsen.

Understanding Craniofacial Development in Children

Think of the tongue as a motor that drives the forward and sideways growth of the maxilla. There is often a direct correlation between compromised oral function and crowded teeth. Developing the upper jaw to be more forward and broader can create more space for the soft tissues to function. This can result in improved breathing and better sleep, two of the most important factors for a healthy human.

By utilizing modern orthodontic tools like removable and fixed expanders, elastics, reverse pull face masks, clear aligners, braces, and CO2 lasers; we can help our children function and develop optimally. We will also work with an ENT doctor, myofunctional therapist, and speech-language pathologist to determine the best solution for your child.

Dental Crowding Is a Sign of Underdevelopment

Dental crowding or two rows of teeth, commonly referred to as “shark teeth,” are just an indication that the jaw structure is too small. Many people assume that dental crowding is caused by having too many teeth or teeth that are too big. However, this is not the case. In fact, dental crowding is typically a sign of an underdeveloped jawbone. This is a common issue, particularly among children.

Two different child with under-developed jaw. The adult teeth coming in have no place to erupt so they need to “double up”.

Waiting is not always the best option

Dysfunction left untreated worsens symptoms. Arch development and crowding worsened in this patient, who waited four years to seek treatment.

Noticed how the palate got narrower without treatment due to
tongue tie and reverse swallowing patterns

Below: 2023, 6 months post expansion. There is actually room for adult teeth. Bite is still deep but showing signs of improvement.

Right: Prior to expansion. Notice 100% overbite where you cannot see
lower teeth when fully closed.

If your child is experiencing snoring, bedwetting, night terrors, disturbed sleep, teeth grinding, or attention issues, these could be signs of sleep disturbances related to an underdeveloped jaw structure. By creating more space for the teeth, the foundation can be developed, and many of these signs will naturally correct themselves.

Post expansion, CO2 tongue tie release, myofunctional therapy. NO orthodontics. The patient achieved perfectly straight aligned teeth, improved overall health, and academic success without medication. Notice the changes in the shape of the palate.

Please call our office if you suspect your child could be suffering from tongue tie or underdevelopment of the jaw. We are passionate about guiding you towards a healthier tomorrow.

Pediatric Dentistry FAQs

What is the best time for my child to see a dentist for the first time?

According to Dr. Alan Ko, your child should see a dentist for the first time around their first birthday or as soon as their first tooth erupts. Early visits will allow Dr. Ko to evaluate your child’s developing oral health with guidance on issues including teething, thumb-sucking, and proper brushing techniques.  What’s more important are the oral structure development (size of the oral volume in relation to the tongue) and how a delayed or underdevelopment of the jaw structure can have long term adult consequences.  Additionally, starting dental visits early helps establish a positive relationship with the dentist and prevents dental issues from developing as your child grows.

How can I help my child feel comfortable about visiting the dentist?

Many children feel nervous about dental visits, but Dr. Alan Ko and his team create a welcoming, friendly environment to make each visit a positive experience. It’s helpful to talk to your child beforehand about the visit in a calm and reassuring way. Dr. Ko uses kid-friendly language and explains what to expect during the appointment, helping children feel at ease.

What should I do if my child has a dental emergency?

If your child experiences a dental emergency, such as a knocked-out tooth, a broken tooth, or severe tooth pain, contact Dr. Alan Ko as soon as possible. Time is critical, especially for a knocked-out tooth—if the tooth is intact, placing it in milk or saline and seeking immediate care can sometimes help save the tooth. Dr. Ko provides guidance on what to do in an emergency and works quickly to relieve your child’s pain and restore their smile.  Years ago when a 6 year old child fell and knocked out her tooth in the playground, Dr. Ko was able to help this young child save her tooth.  Still to this day, she still has her tooth!

When should my child start brushing their teeth?

Dr. Alan Ko recommends starting oral hygiene practices when your child’s first tooth appears. Infants and toddlers should use a soft-bristled toothbrush with a small amount of fluoride toothpaste to clean their teeth gently. As they grow, please encourage your child to brush twice daily, guiding them to use the correct amount of toothpaste.

How can I prevent cavities in my child’s teeth?

Preventing cavities begins with good oral hygiene and a healthy diet. Dr. Alan Ko advises brushing your child’s teeth twice daily, flossing once they have two teeth that touch, and limiting sugary foods and drinks. Ideally, non-processed food will be the most healthy for your children’s body and teeth!  Regular dental checkups are also essential for detecting early signs of cavities and providing fluoride treatments, which help strengthen teeth and prevent decay. Additionally, Dr. Ko may recommend dental sealants for children, which act as a protective barrier on the back teeth.

Are baby teeth really that important?

Yes! Baby teeth play an essential role in your child’s oral development. Dr. Alan Ko explains that baby teeth help children speak clearly, chew food properly, and hold space for the permanent teeth that will come later. If baby teeth decay or are lost too early, it can affect the alignment and development of adult teeth.

How can I help my child transition to wearing braces?

The transition to braces can be exciting yet sometimes challenging for children.  This is what regular check ups are important!  If a child has a tongue tie, we often see under-development of the jaw structure which at age 6 or 7, we start to see crowding of the permanent teeth.  Our position has always been developing the jaw to the proper size to allow adult teeth to come in without crowding, which is rarely seen these days.  Dr. Alan Ko ensures that children are well-prepared for the orthodontic process (mentally and biologically), explaining what to expect and addressing any concerns. Parents can support their children by helping them maintain a consistent oral hygiene routine, especially when wearing braces, to avoid cavities and gum problems.
