I Make Airway and Dental Health Simple for Parents

If you’ve been told everything looks fine but your gut says otherwise, you are not alone. That is how many families find me.
They’ve seen the signs. Snoring. Feeding challenges. Restless sleep. Picky eating. Cavities that keep coming back. Many have been to multiple providers, but no one connected the dots. That’s what I do.
I help parents see the full picture and take action that supports long-term health.

Why I Look atMore Than Just Teeth

Why I Look at
More Than Just Teeth

In school, I was trained to fix teeth. Fill the cavity. Straighten the smile. Move on. But in the real world, I saw children who were struggling in ways that dental charts didn’t explain. I saw parents who felt unheard. And I saw patterns: mouth breathing, poor sleep, repeated cavities, attention challenges that kept getting missed.

The answers were not in the teeth alone. They were in how the tongue moved, how the jaws were growing, and how the child was breathing and sleeping. Once I started asking different questions, everything changed. For me. And for the families I care for.

“Why Did No One Tell Me This?”

Education Background

Dr. Billy Arnold is a board-certified pediatric dentist specializing in functional oral development, airway-centered dentistry, and early growth guidance. He earned his Bachelor’s degree in Physiology and Neuroscience from the University of California, San Diego and his Doctor of Dental Surgery from the Herman Ostrow School of Dentistry of USC, where he graduated on the Dean’s List and received the USC Senior Dental Student Award. He went on to complete a two-year pediatric dental residency at Children’s Hospital Los Angeles, earning a Certificate in Advanced Pediatrics through USC.
 
During residency, Dr. Arnold began his focused research on ankyloglossia, oral dysfunction, and pediatric breathing health—specifically examining how airway disorders impact growth, behavior, sleep quality, and feeding. This ignited his passion for redefining pediatric dentistry through an airway-first lens.
 
After residency, he continued practicing in a hospital setting at St. Francis Children’s Hospital in Tulsa, Oklahoma, before returning home to Southern California. He now practices in Orange County and the Bay Area.
 
Dr. Arnold is a Diplomate of the American Board of Pediatric Dentistry and serves as Chair of the Pediatric Research Committee and Board Member for the Foundation for Airway Health. He is also a board member of the Southern California Society of Dentistry for Children and an active member of the American Academy of Physiological Medicine and Dentistry, the California Society of Pediatric Dentistry, and the American Academy of Pediatric Dentistry.
 
His advanced clinical expertise includes early interceptive airway orthodontics, tethered oral tissues (tongue-ties and lip-ties), functional growth guidance, and providing care for children with special needs in both traditional and hospital settings.
 
Above all, Dr. Bill’s passion is helping babies nurse, kids develop and families thrive by partnering with families to support healthy habits, strong development, and confident, thriving kids.

What I Believe

Parents deserve real answers

You should never feel dismissed. I listen fully, explain clearly, and give you the tools to make confident, informed decisions.

Function comes first

I do not treat appearance alone. I look at how the body is working. From tongue posture to breathing habits to how a child sleeps at night.

Earlier is better

Most jaw and airway growth is complete by age twelve. Early guidance can prevent major treatment later and support a child’s energy, focus, and development now.

The body is connected

Oral health is deeply linked to sleep, speech, nutrition, posture, and more. I look at the whole child, not just the mouth.

Care should never be isolated

work closely with therapists, pediatricians, lactation consultants, ENTs, and other professionals. No parent should have to navigate this alone

What I Want You to Know

You do not need to know the right terms. You do not need to come in with all the answers. If something feels off, we can look together.
Sometimes the next step is simple. Sometimes it takes a team. But either way, we’ll move forward with clarity, compassion, and consistency.
I’ve trained extensively in airway dentistry, pediatric sleep, tongue tie treatment, and early jaw development. I continue to study under leaders in the field because I believe children deserve the best of what we know, not just what we were taught ten years ago.
I do this work because I’ve seen what’s possible when the right care meets the right moment in a child’s life. That is what keeps me learning and showing up fully every day.

What toExpect When Your Child Is In My Care

  • You will be heard
  • I will explain everything in plain language
  • You will not be rushed or overwhelmed
  • Your child will be treated with respect and kindness
  • Your child will be treated with respect and kindness
  • I will coordinate care when needed so nothing falls through the cracks
  • We will work together as partners in your child’s health

What Families Say

“He didn’t just clip the tie. He helped us build a whole plan.”

“It’s the first time I felt like someone was truly in our corner.”

What Comes Next

If my approach feels like the kind of care your child needs, I would be honored to meet you.
