Does Your Child Need a Mouthguard for Sports?

If your child plays a sport where contact or a flying ball is possible, a mouthguard is one of the simplest ways to protect their teeth. A single hit to the mouth can chip, loosen, or knock out a tooth, and a mouthguard absorbs much of that force. Knowing when one is worth it and how to choose the right kind saves a lot of trouble, including the kind of dental emergency a knocked-out tooth becomes. Here is which sports call for a mouthguard, the options, and how to get a good fit for a growing mouth.

Quick answer: A mouthguard cushions a child’s teeth from impact during sports and can prevent chipped, loosened, or knocked-out teeth. It is worth wearing in any sport with contact or a hard ball or stick, which covers football and hockey but also basketball, soccer, and skateboarding. Options range from stock and boil-and-bite guards to a custom one made by a dentist. A custom fit is the most comfortable and protective, which makes a child likelier to wear it.

What a mouthguard protects against

A mouthguard is a cushion for the teeth. When something hits the mouth, a ball, an elbow, the ground, the guard spreads and absorbs the force that would otherwise crack a tooth, push it loose, or knock it out entirely. It also lowers the chance of cuts to the lips and tongue and can reduce the jolt to the jaw. Guidance on protecting children’s teeth during sports points to mouthguards as a standard piece of protective gear for this reason.

Dental injuries in sports are common and often avoidable. A knocked-out permanent tooth is a true emergency, and even a chipped front tooth can mean repeated dental work over a childhood. A mouthguard is a small, cheap piece of equipment that prevents a disproportionate amount of that damage.

Which sports actually call for one

Most parents think of football and hockey, and those clearly qualify, but the list is longer than the obvious contact sports. Basketball and soccer, despite not being collision sports, produce a lot of mouth injuries from elbows, heads, and the ball. Any sport with a stick, a bat, or a hard ball, like baseball, lacrosse, and field hockey, carries real risk.

It is worth thinking beyond organized team sports too. Skateboarding, scootering, biking, and gymnastics all involve falls that can land on the face. The simple rule of thumb: if there is a meaningful chance of a blow to the mouth, from another player, equipment, or the ground, a mouthguard earns its place.

The three main types

There are three broad options, and they trade off cost against fit. Stock mouthguards come ready to wear off the shelf, are the cheapest, but fit poorly and tend to be bulky, which makes children less likely to keep them in. Boil-and-bite guards, sold at sporting goods stores, are softened in hot water and then bitten into to mold roughly to the teeth, giving a better fit than stock at a low price.

The third option is a custom mouthguard made by a dentist from a mold of your child’s mouth. It costs more, but it fits closely, feels comfortable, stays in place, and offers the best protection. The comfort matters more than it sounds: a guard that fits well is one a child will actually wear, while a bulky, ill-fitting one ends up in the gym bag.

Fitting a mouth that is still changing

Children’s mouths are a moving target, with baby teeth falling out and permanent teeth coming in over several years. That changes how a mouthguard should be approached. A guard that fit well at the start of a season may not fit by the end if your child has lost or gained teeth, so it needs checking and replacing more often than an adult’s would.

For a child losing and growing teeth quickly, a boil-and-bite guard that can be re-fitted, or a custom guard designed with the changing dentition in mind, works better than a rigid stock one. A dentist can advise on timing a custom guard so it is not outgrown in a few months, and can refit or remake it as the mouth changes.

Caring for the mouthguard

A mouthguard only works if it stays clean and intact. Rinsing it before and after each use, brushing it gently with a toothbrush, and letting it dry before storing it in a ventilated case keeps bacteria down. Storing it away from heat matters, since a hot car or direct sun can warp the shape and ruin the fit.

It is worth checking the guard regularly for tears, thinning, or rough edges, all of which mean it is time to replace it. Children also tend to chew on their guards, which wears them out faster. A worn guard protects less, so replacing it when it shows damage, or when your child’s mouth has changed, keeps the protection real.

When to ask your dentist

If your child is starting a sport, a quick conversation with the dentist about whether a guard makes sense and which type to use is worth having. A dentist can fit a custom guard, advise on timing around your child’s changing teeth, and check that an existing guard still fits. And if an injury does happen despite a guard, knowing what counts as urgent matters: a knocked-out or badly broken tooth needs fast action, which is where our emergency care comes in. A first visit is a good time to raise mouthguards if your child is active in sports.
