If your child plays sports, you already pack the cleats, the shin guards, and the water bottle. The mouthguard is the small piece of gear that is easiest to forget and one of the most important to remember. A single elbow, a stray ball, or a hard fall can chip, break, or knock out a tooth in a fraction of a second, and unlike a scraped knee, a damaged permanent tooth does not grow back.
The good news is that protection is simple and affordable. A mouthguard is a small, comfortable shield that absorbs the force of a hit before it reaches your child's teeth, lips, and jaw. Here is what our team at Pediatric Dentistry by Dr. Jeffries wants every sports family across North Carolina to know about choosing one, fitting it, caring for it, and getting your child to actually keep it in.
Why a Mouthguard Matters More Than Parents Think
Dental injuries are one of the most common injuries in youth sports, and they tend to happen fast and without warning. A blow to the face can crack a front tooth, push a tooth out of place, cut a lip against the teeth, or knock a tooth out completely. Some of these injuries are painful and expensive to repair. Others follow a child for the rest of their life, since a lost or badly damaged permanent tooth may need ongoing dental work for decades.
A mouthguard works by spreading and softening the force of an impact. Instead of a hard hit landing on a single tooth, the guard cushions the blow and shares it across the whole arch. That same cushioning helps protect the lips, tongue, and jaw, and it can lower the chance of a chipped tooth turning into a deeper break. For a small piece of equipment, it does a lot of work.
It is also worth saying what a mouthguard cannot do. It is not a helmet, and it does not replace one. But for the teeth and the soft tissue around them, it is the single best layer of protection your child can wear, and it costs far less than fixing the damage it prevents.
Which Sports Need a Mouthguard?
When parents hear "mouthguard," they usually think of football or hockey. Those are obvious, but they are far from the only sports where teeth are at risk. Any activity where a child might collide with another player, the ground, a ball, or a piece of equipment is a candidate.
We recommend a mouthguard for contact and collision sports such as:
- Football, hockey, lacrosse, and wrestling. High-contact sports where blows to the face are common and expected.
- Basketball and soccer. These surprise a lot of parents, but elbows, heads, and the ball itself send plenty of kids to the dentist every season.
- Baseball and softball. A bad hop or an errant bat or ball can do real damage in a hurry.
- Martial arts and boxing. Direct strikes to the head and face make a guard a basic requirement.
It is smart to consider one for individual and wheeled activities too, including skateboarding, mountain biking, and gymnastics, where a fall onto a hard surface is always a possibility. A simple rule helps: if there is a reasonable chance of a hit to the mouth, a mouthguard belongs in the bag.
The Three Types of Mouthguards, Honestly Compared
Mouthguards come in three main types. They all protect the teeth, but they differ a lot in fit, comfort, and price. Here is an honest look at each so you can choose with open eyes.
1. Stock Mouthguards
These come ready to wear, straight off the shelf, in small, medium, and large.
- Pros: The cheapest option and available almost anywhere. They offer some protection in a pinch.
- Cons: They cannot be adjusted, so the fit is usually bulky and loose. A loose guard shifts around, makes it hard to talk and breathe, and a child often ends up clenching it in place or simply spitting it out. A guard that does not stay put does not protect well.
2. Boil-and-Bite Mouthguards
These are the most popular store-bought option. You soften the guard in hot water, then have your child bite down so it molds to their teeth.
- Pros: Affordable, easy to find at any sporting goods store, and a noticeably better fit than a stock guard once molded correctly. A good choice for many recreational athletes.
- Cons: The fit is only as good as the molding job, and getting it right at the kitchen sink can take a few tries. They wear out faster, can feel bulky, and do not match the precision of a guard made from a mold of your child's actual teeth.
3. Custom-Fitted Mouthguards from the Dentist
These are made just for your child. We take an impression or scan of their teeth and build a guard that fits exactly.
- Pros: The best fit, comfort, and protection by a wide margin. A custom guard is thinner where it can be and thicker where it needs to be, stays put on its own, and makes it easier to breathe and talk. Because it is comfortable, kids are far more likely to keep it in for the whole game, which is the entire point.
- Cons: It costs more than a store-bought guard and requires a visit. For many families, the comfort and protection are well worth it, especially for kids in high-contact sports or those who wear braces.
Fit, Comfort, and Why a Kid Actually Wears It
The best mouthguard in the world does nothing sitting in a gym bag. The hard truth is that kids skip the ones that bother them, and a guard that is bulky, loose, or hard to breathe through gets "forgotten" fast. So comfort is not a luxury here. It is what makes the protection real.
A well-fitting guard stays in place without being clenched, lets your child breathe and speak clearly enough to call a play, and does not trigger gagging. This is exactly where a custom guard earns its keep, since it is built to your child's mouth rather than a one-size box. If you go with a boil-and-bite, take your time on the molding step and redo it if the fit feels loose or thick.
A quick word on braces. If your child wears braces, a properly fitted mouthguard becomes even more important, since a hit to the mouth can drive the lips and cheeks into the brackets. Ask us about a guard designed to work with orthodontic hardware rather than a standard boil-and-bite, which may not fit well over braces.
Keeping the Mouthguard Clean
A mouthguard spends a lot of time in a warm, damp gym bag, which is exactly where bacteria like to grow. A little care keeps it fresh and safe to use:
- Rinse before and after every use with cool water, or brush it gently with a toothbrush and a little toothpaste.
- Let it dry fully before storing it, since a damp guard breeds bacteria.
- Store it in a firm, vented case, not loose in the bottom of a bag where it can get crushed or dirty.
- Keep it out of the heat. Hot water, a sunny car, or a dishwasher can warp the guard and ruin the fit. Cool water only.
- Check it often. Bring it to dental visits so we can take a look at the fit and condition.
When to Replace a Mouthguard
Mouthguards do not last forever, and children are a special case because their mouths are still growing and new teeth are still coming in. A guard that fit perfectly last season may be too small or loose this season.
Replace your child's mouthguard when you see any of the following: tears, holes, or rough chewed-through spots; a fit that has turned loose or no longer covers all the teeth; a noticeable change in your child's bite or new teeth coming in; or simply a guard that has been through a long, hard season. Many growing kids need a fresh guard each sports season, and any guard showing real wear should be retired right away. When in doubt, bring it in and we will check it.
When to See Us
If your child is starting a new sport, the best time to ask about a custom mouthguard is before the season begins, not after the first injury. We are happy to talk through whether your child's sport, age, and stage of tooth development call for a custom guard or whether a well-fitted boil-and-bite will do the job for now.
And if an accident does happen, knowing what to do in the first few minutes can save a tooth. Our guide on what to do when a child knocks out a tooth walks you through the steps to take right away. A mouthguard makes that emergency far less likely in the first place, which is the whole reason we bring it up so often.
Protecting your child's smile during sports is one of the simplest wins in parenting. The right guard, fitted well and worn every game, prevents injuries that are painful, costly, and sometimes permanent. If you are getting ready for a new season, a checkup is a great time to ask about it, and our guide on summer dental care covers more ways to keep those smiles healthy through the active months.
If it has been more than six months since your child's last checkup, we would love to see you. Our team is here to help your family stay safe, healthy, and ready to play.
