When we think about nutrition, we often focus on how it fuels the body, supports growth, and prevents illness. But did you know that what your child eats also plays a critical role in jaw development and future orthodontic health?
At Larson Orthodontics, we look at the big picture. A healthy smile starts long before braces or aligners ever come into play—and the foundation often begins at the dinner table. In this post, we’ll explore how diet affects jaw growth, what foods support healthy development, and how nutrition choices can impact the need for orthodontic treatment later on.
Why Jaw Development Matters
A properly developed jaw allows teeth to erupt in the right positions, supports healthy breathing, and contributes to clear speech and facial balance. When the jaw is underdeveloped—either too narrow or not forward enough—it can lead to:
- Crowded or crooked teeth
- Crossbites, overbites, or underbites
- Mouth breathing
- Poor posture or facial asymmetry
- Speech difficulties
- Higher risk of sleep-disordered breathing
These issues may require orthodontic appliances, palatal expanders, or even jaw surgery later in life. But the good news? Dietary choices during early childhood can make a difference.
How Diet Influences Jaw Growth
The jaw bones, like all bones in the body, respond to use and nutrition. A diet that encourages chewing and provides essential nutrients helps stimulate proper development. Here’s how:
1. Chewing Builds Strong Jaws
In generations past, children regularly chewed tougher, more fibrous foods—like fresh fruits and vegetables, whole grains, and meat off the bone. This constant chewing motion helped stimulate jaw muscle development and bone growth.
Today, many children eat softer, more processed foods (think crackers, applesauce, and yogurt pouches). While these are easy to consume, they don’t give the jaw the same workout, which can contribute to underdeveloped arches and bite issues.
2. Nutrients Fuel Bone and Tissue Growth
A well-balanced diet gives the body the building blocks it needs for strong bones, healthy gums, and properly erupting teeth. Key nutrients include:
- Calcium – builds strong bones and teeth (found in dairy, leafy greens, fortified foods)
- Vitamin D – helps the body absorb calcium (found in sunlight, fish, fortified milk)
- Magnesium and phosphorus – support bone structure
- Vitamin C – essential for healthy gums and connective tissue
- Protein – supports muscle and bone development
Deficiencies in any of these can impact both dental and skeletal development.
Foods That Support Healthy Jaw Development
Encourage a diet that promotes both nutrition and jaw exercise. These foods can help:
Chewy & Crunchy (But Healthy) Foods
- Raw fruits and vegetables: apples, carrots, celery, cucumbers
- Whole grains: hearty breads, granola, brown rice
- Lean meats: grilled chicken, steak, jerky (for older kids)
- Nuts and seeds (as appropriate by age)
Calcium & Vitamin D-Rich Foods
- Milk, cheese, yogurt
- Fortified plant-based milks
- Leafy greens like kale and spinach
- Salmon, sardines, and eggs
Hydrating, Low-Sugar Foods
- Water-rich fruits like melons and oranges
- Water (instead of sugary drinks) to support saliva flow and oral health
Habits That Can Undermine Jaw Development
Just as certain foods and nutrients help, there are habits and dietary patterns that can hinder proper jaw growth—especially during the early developmental years.
- Excessive soft food intake — Not enough chewing = underused muscles
- Prolonged pacifier use or thumb sucking — Can alter jaw and palate shape
- Mouth breathing — Often tied to allergies or airway obstruction, but can lead to narrow jaws and long-face syndrome
- Sugary snacks and drinks — Promote inflammation and gum disease, affecting oral tissue health
If your child struggles with picky eating, especially avoiding chewy or textured foods, it may be worth discussing with both your pediatrician and orthodontist.
How Orthodontics Can Support Jaw Development
While diet lays the foundation, orthodontics can step in when additional guidance or correction is needed. At Larson Orthodontics, we evaluate jaw growth and bite development as early as age 7—often before all the permanent teeth have come in.
Depending on what we see, early intervention may include:
- Palatal expanders to widen the upper jaw
- Growth modification appliances to guide jaw positioning
- Monitoring and dietary guidance to support continued development
- Myofunctional therapy referrals for issues like tongue thrust or mouth breathing
Our goal is always to promote the most natural, effective growth possible while minimizing the need for more invasive treatments later.
It All Starts with Smart Habits Early On
The foods your child eats today help shape their smile for life. By promoting healthy chewing, strong bones, and good oral habits, you’re setting the stage for better alignment, fewer complications, and even shorter orthodontic treatment down the road.
At Larson Orthodontics, we’re proud to work hand-in-hand with families to support every aspect of their child’s smile journey—from early growth to braces and beyond.
