When it comes to protecting your child’s smile, brushing and flossing are just the beginning. For active kids whether they’re playing sports, roughhousing with friends, or grinding their teeth at night a well-fitted kids mouth guard can make all the difference in preventing injuries that could impact their oral health for years to come.

Parents often think of mouth guards as something only pro athletes wear. But the truth is, children face just as many risks to their teeth from organized sports and after-school activities to nighttime habits that go unnoticed until damage appears.

In this guide, we’ll walk through when your child might need a mouth guard, the different types available, and how to choose the right option based on their age, lifestyle, and dental development.

What Is a Kids Mouth Guard?

A kids mouth guard is a protective device made to cushion your child’s teeth, lips, jaw, and gums from impact or pressure. It’s worn over the upper teeth and designed to absorb shock, reduce the risk of injury, and protect both baby and permanent teeth.

Children wear mouth guards for different reasons:

• Contact sports like football, hockey, lacrosse, and boxing
• High-speed activities like biking, skating, or gymnastics
• Orthodontic protection (especially with braces)
• Nighttime teeth grinding (also known as bruxism)
• General play or roughhousing that could result in falls or facial impact

Why a Kids Mouth Guard Matters

Children’s teeth and jaws are still developing and that makes them especially vulnerable to trauma. A kids mouth guard offers essential protection by:

• Preventing broken or chipped teeth
• Reducing the risk of jaw injury
• Protecting lips, cheeks, and tongue from lacerations
• Preserving orthodontic appliances during physical activity
• Cushioning nighttime grinding to avoid enamel erosion and jaw strain

The American Dental Association recommends mouth guards for all children participating in sports and recreational activities with a risk of impact. Yet many parents are unaware that even a minor fall or bump can lead to costly dental work or worse, long-term oral health issues.

When Should Your Child Start Wearing a Mouth Guard?

If your child is involved in any of the following activities, it may be time to consider a kids mouth guard:

• Contact or collision sports (football, hockey, basketball)
• Solo sports or activities with fall risk (skateboarding, gymnastics)
• Wearing braces during play
• Complaints of jaw soreness or tooth sensitivity after sleeping
• Evidence of grinding or clenching at night

At Tribeca North Dentistry, our team regularly evaluates children for signs of wear, grinding, and sports-related risks. We’ll help you determine whether your child would benefit from a custom-fit mouth guard and guide you toward the best solution for their age and activity level.

Types of Kids Mouth Guards: What to Know

There are three main types of kids mouth guards available:

1. Stock Mouth Guards

These pre-formed guards are inexpensive and ready to wear but often fit poorly. Because they’re not customized, they can feel bulky and may be uncomfortable making it less likely your child will wear them consistently.

2. Boil-and-Bite Mouth Guards

Available at most sporting goods stores, these guards are softened in hot water and molded around your child’s teeth. They offer a slightly better fit than stock options but may still cause irritation or wear down quickly.

3. Custom Mouth Guards

Made by your child’s dentist using an impression of their teeth, custom guards offer the best fit, comfort, and protection. They’re especially beneficial for children with braces, bite alignment concerns, or those who grind their teeth.

Custom mouth guards are also easier to wear long-term whether during games or overnight because they stay in place, don’t interfere with speech, and are molded to your child’s specific anatomy.

A Mouth Guard for More Than Just Sports

While many parents think of sports when it comes to mouth guards, nighttime grinding is a common concern we see at our practice. If your child wakes up with jaw soreness, has unexplained headaches, or you hear grinding noises during sleep, a custom night guard may help.

Bruxism can wear down enamel, cause gum recession, and even affect how adult teeth come in. A kids mouth guard worn during sleep can minimize these risks, protect developing teeth, and prevent long-term complications.

And if you’re already focusing on building healthy habits at home like nutritious snacking and regular brushing this is a great next step.

Caring for Your Child’s Mouth Guard

To ensure your child’s mouth guard remains clean and effective:

• Rinse it after each use with cool water
• Clean regularly with a soft toothbrush and mild soap
• Avoid hot water, which can warp the material
• Store it in a ventilated case
• Check for wear and bring it to dental visits for inspection

Replacing the mouth guard yearly or sooner, depending on your child’s growth is essential for comfort and performance.
