How Mouth Guards Help Prevent Dental Injuries in Children

August 1, 2026

One minute, your child is chasing a soccer ball. Next, they’re holding their mouth in pain after an accidental collision. Dental injuries often happen without warning, turning an exciting game into an unexpected trip to the dentist. The good news is that many of these injuries are preventable. Mouth guards in Plainfield offer a simple yet effective way to protect growing smiles during sports and other high-impact activities, helping children stay active while lowering the risk of serious dental trauma.

Understanding Dental Injuries in Children

Children are naturally active, and falls, collisions, and sports-related accidents are common. As per the ADA, athletes who do not wear a mouth guard are significantly more likely to experience dental injuries than those who do.

Common dental injuries include:

  • Chipped or broken teeth
  • Knocked-out permanent teeth
  • Cracked teeth
  • Cuts to the lips, cheeks, or tongue
  • Jaw injuries

These injuries may require emergency dental treatment and, in some cases, long-term restorative care. A little prevention today can spare children from painful injuries and extensive dental care later.

What Is a Mouth Guard?

A mouth guard is a protective barrier over the teeth, reducing the force of an impact and helping prevent damage to the teeth, gums, and jaw. Instead of allowing a direct blow to damage the teeth or jaw, it cushions the mouth and reduces the severity of injuries.

Although mouth guards are commonly associated with contact sports, they can also protect children during many recreational activities where falls or collisions are possible.

How Mouth Guards Protect Children’s Teeth

When fitted correctly, a mouth guard cushions the teeth and nearby tissues by helping disperse the force from a blow or collision.

It helps protect by:

  • Cushioning the front teeth from direct blows
  • Lowering the chance of chipped or fractured teeth
  • Helping reduce soft tissue injuries inside the mouth
  • Providing additional protection for the jaw
  • Decreasing the risk of damaging dental restorations or orthodontic appliances

Expert Insight

Children with braces should wear specially designed mouth guards. Orthodontic appliances increase the risk of cuts to the lips and cheeks during an accident, making protection even more important.

Sports and Activities That Require Mouth Guards

Many parents think only football players need mouth guards. In reality, numerous sports carry a risk of dental injury.

Children should consider wearing one during:

  • Football
  • Basketball
  • Baseball and softball
  • Soccer
  • Hockey
  • Wrestling
  • Martial arts
  • Skateboarding
  • Gymnastics
  • BMX riding
  • Roller skating
  • Lacrosse

Even activities without frequent contact can involve unexpected falls or collisions.

Types of Mouth Guards for Children

Not every mouth guard provides the same level of protection.

Stock Mouth Guards

These are pre-made and available in sporting goods stores. While affordable, they often fit poorly and may feel bulky.

Boil-and-Bite Mouth Guards

These soften in hot water before being molded to the child’s teeth. They generally fit better than stock options but may still offer inconsistent protection.

Custom Mouth Guards

Custom-made guards are created using impressions of a child’s teeth. They provide the best fit, improved comfort, and reliable protection, especially for children who regularly participate in organized sports.

A pediatric dentist in Plainfield can guide you toward the best option by evaluating your child’s age, oral development, and the activities they participate in.

Benefits of Wearing a Mouth Guard

A mouth guard does much more than protect teeth.

Its advantages include:

  • Lower risk of broken or knocked-out teeth
  • Better protection for gums and lips
  • Greater comfort during sports
  • Reduced likelihood of costly emergency dental treatment
  • Confidence for both children and parents

A comfortable fit encourages children to wear their mouth guard every time they play.

Choosing the Right Mouth Guard

Selecting the right mouth guard involves more than choosing one off a store shelf.

Consider these factors:

  1. Proper fit without restricting breathing.
  2. Comfortable enough for regular use.
  3. Durable material that withstands repeated impacts.
  4. Easy to clean after every use.
  5. Appropriate design for braces if orthodontic treatment is underway.

If you search for a “pediatric dentist near me”, you can also ask about professionally fitted mouth guards designed specifically for growing smiles.

Caring for a Child’s Mouth Guard

A clean mouth guard lasts longer and helps maintain good oral hygiene.

Encourage your child to:

  • Rinse it with cool water before and after each use.
  • Gently clean the mouth guard with mild soap and a soft toothbrush after use.
  • Allow it to air dry completely.
  • Store it in a ventilated protective case.
  • Keep it away from high temperatures, which can cause it to lose its shape.

Inspect the guard regularly for tears, cracks, or signs of wear.

When to Replace a Mouth Guard

A child’s mouth changes over time, so a mouth guard that once fit well may eventually need to be replaced. A mouth guard that fit perfectly last season may no longer provide proper protection.

Replace it if:

  • It becomes loose.
  • It develops cracks or holes.
  • Your child has significant dental changes.
  • Permanent teeth have erupted.
  • Orthodontic treatment changes the bite.

Regular checkups help ensure your child’s mouth guard still fits well as their teeth and jaw continue to grow.

Final Thoughts: Protecting Your Child’s Smile

Children deserve the freedom to play, compete, and explore without unnecessary risks to their oral health. Wearing properly fitted mouth guards in Plainfield is one of the simplest ways to reduce the likelihood of dental injuries and help preserve healthy, developing teeth. Regular dental checkups also ensure the guard continues to fit as your child grows.
