Magnesium & Your Child’s Smile: The Overlooked Mineral That Supports Healthy Teeth

When parents think about strong teeth, the first mineral that comes to mind is usually calcium—and for good reason! Calcium plays a huge role in building strong bones and enamel. But there’s another essential mineral that often gets overlooked and is just as important for your child’s dental health: magnesium.

At Dr. Sugar Children’s Dentistry in Paradise Valley, AZ, we love helping parents understand how simple nutrition choices can make a big difference in their child’s smile. Here’s why magnesium deserves a spot on your family’s daily wellness radar.

What Does Magnesium Do for Kids’ Teeth?

Magnesium plays a surprising number of roles:

1. Helps the Body Absorb Calcium Properly

Magnesium and calcium work as a team. Without enough magnesium, the body can’t use calcium effectively—even if your child eats plenty of it. That means weaker enamel and higher risk of cavities.

2. Supports Strong Enamel Formation

Enamel is the outer shield of the tooth, and magnesium helps strengthen this protective layer, making it harder for bacteria and acids to cause decay.

3. Reduces Inflammation in the Mouth

Children who struggle with swollen gums or early signs of gingivitis may benefit from better magnesium intake. It supports healthy gum tissue and reduces irritation.

4. Essential for Overall Growth

Magnesium helps with muscle function, nerve signaling, and bone strength—all of which support healthy oral development.

How Much Magnesium Do Kids Need?

Daily amounts vary by age, but here’s a simple guide:

4–8 years old: ~130 mg per day

9–13 years old: ~240 mg per day

Always check with your pediatrician before adding supplements, especially if your child has dietary restrictions.

Kid-Friendly Foods High in Magnesium

The best part? Many magnesium-rich foods are easy to add to your child’s diet:

Bananas

Almonds and cashews

Oatmeal

Spinach (blended in smoothies!)

Whole-grain bread

Yogurt

Avocado

Black beans

Try pairing these foods with calcium-rich favorites like cheese or yogurt to help both minerals work together.

Signs Your Child May Not Be Getting Enough Magnesium

While only a health professional can diagnose a deficiency, some parents notice:

Muscle cramps

Low energy

Trouble sleeping

Increased cavities

Sensitive gums

If you have concerns, your kids dentist or pediatrician can help guide next steps.
