Does My Child Need a Mouthguard for Sports? An Orange County Pediatric Dentist Explains

Every weekend across Orange County, kids are suiting up for soccer, baseball, basketball, flag football, and martial arts. Parents pack snacks, fill water bottles, and remember sunscreen. But one of the most important pieces of protective gear often gets left behind — or never purchased at all.

A sports mouthguard takes about 30 seconds to put in and costs a fraction of what a single knocked-out tooth costs to treat. Yet the American Dental Association estimates that fewer than 40% of youth athletes wear one consistently.

Here is what every Orange County parent with an active kid should know.

Why Teeth Are More Vulnerable During Sports Than You Think

Dental injuries are among the most common sports injuries in children, accounting for roughly one third of all traumatic dental injuries seen in pediatric dental offices. The mouth is exposed and unprotected during nearly every contact and collision sport — and many non-contact ones too.

A single blow to the face can knock out a tooth, fracture enamel, push a tooth into the gum, or damage the root in ways that are not visible but have long-term consequences. We cover what to do when these emergencies happen in our pediatric dental emergency guide, but prevention is always the better strategy.

What makes sports injuries particularly significant for children is that their permanent teeth are still maturing. A traumatized tooth in a child may not show the full extent of damage for months or even years.

Which Sports Actually Require a Mouthguard?

Most parents associate mouthguards with football or boxing, but the data tells a more complicated story. Some of the highest rates of dental injury in children occur in sports where mouthguards are not traditionally required or expected.

High-risk sports where mouthguards are strongly recommended:

Basketball is consistently among the top sports for dental injuries in children despite having no equipment requirement for mouth protection. Elbows, heads, and hardwood floors make for a dangerous combination.

Soccer involves frequent aerial challenges, collisions, and falls — all of which can result in facial impact. Youth soccer players are particularly vulnerable.

Baseball and softball carry risk from pitches, batted balls, and collisions at bases. Catchers are especially exposed.

Martial arts, wrestling, and gymnastics all involve physical contact or fall risk that puts the mouth in danger.

Sports where mouthguards are already required or commonly worn:

Football, hockey, lacrosse, and boxing typically mandate mouthguards through league rules, which reflects how well established the risk is in these sports.

If your child plays any sport where they could fall, collide with another player, or be struck by equipment, a mouthguard is worth wearing — regardless of whether the league requires one.

The Three Types of Mouthguards: What Parents Need to Know

Not all mouthguards offer equal protection. Understanding the differences helps you make the right choice for your child.

Stock mouthguards are pre-formed, come ready to wear, and are sold at most sporting goods stores for a few dollars. They are better than nothing but offer the least protection because they cannot be adjusted to fit your child's mouth. Many kids find them bulky and uncomfortable, which means they end up in the bottom of the equipment bag.

Boil-and-bite mouthguards are the most common choice for youth athletes. They are softened in hot water and then molded to the shape of your child's teeth by biting down. They fit better than stock guards, cost between $15 and $30, and are available at most sporting goods stores. For most children playing recreational sports, this is a reasonable starting point.

Custom mouthguards are made by a dentist from an impression of your child's teeth. They offer the best fit, greatest comfort, and superior protection because they are designed specifically for your child's mouth. Children are more likely to actually wear them because they are comfortable. They typically cost between $200 and $500 depending on materials and where they are made.

If your child is in orthodontic treatment or has had recent dental work, a custom guard from Dr. Jae is the right choice — store-bought options often do not accommodate braces or retainers properly.

Mouthguards and Braces: A Common Question

One of the most frequent questions we hear from parents of young athletes is whether a mouthguard can be worn over braces. The answer is yes, but with some important considerations.

Standard boil-and-bite guards should not be used over braces because the heat molding process can warp around brackets and wires, creating a guard that no longer fits correctly and may even damage the orthodontic hardware. There are specially designed orthodontic mouthguards available at sporting goods stores that provide a looser fit to accommodate brackets.

However, for the best protection and comfort during orthodontic treatment, a custom mouthguard made by a pediatric dentist is the ideal solution. It can be designed to fit over braces precisely and updated as treatment progresses.

How to Get Your Child to Actually Wear It

Owning a mouthguard and wearing it are two different things. Here are practical strategies that work with kids:

Let them choose it. Kids who pick their own color or design are significantly more likely to use it consistently. This is a small thing that makes a real difference.

Make it part of the routine. Mouthguard goes in with the shin guards, cleats, or helmet — not as an afterthought, but as a standard part of suiting up. Build the habit when they first start playing a sport.

Talk about why, not just what. Children respond better to reasons than commands. Explain that the mouthguard protects the teeth they will have for the rest of their life. A child who understands the stakes is more cooperative than one who is simply told to do it.

Lead by example. If you play recreational sports, wear protective gear yourself. Children watch what parents do far more closely than what they say.

Check the fit regularly. A mouthguard that has become loose, cracked, or misshapen is uncomfortable and less effective — and a child will quietly stop wearing it. Check it at the start of each season and replace it if it no longer fits snugly.

Caring for a Mouthguard

A mouthguard that is not maintained becomes a breeding ground for bacteria — counterproductive for a device sitting in your child's mouth. Basic care is simple:

Rinse it with cold water before and after each use. Brush it gently with a toothbrush and mild soap, not toothpaste, which can be abrasive. Store it in a ventilated hard case — not loose in an equipment bag where it can be crushed or contaminated. Keep it out of direct sunlight and away from heat, both of which can warp the material. Replace it at the start of each sports season, or sooner if it shows signs of wear.

What Happens If a Tooth Gets Knocked Out Anyway

Even with a mouthguard in place, accidents happen. If your child loses a permanent tooth during a game or practice, time is critical. The tooth can often be saved if you act within 30 to 60 minutes.

Pick the tooth up by the crown, never the root. If it is dirty, rinse it gently with water — do not scrub or dry it. Try to place it back in the socket if your child is old enough to cooperate, or store it in a container of cold milk. Get to a pediatric dentist immediately.

Our full guide to pediatric dental emergencies walks through exactly what to do in these situations, step by step. Save it in your phone before the season starts.

When to Ask Your Dentist About a Mouthguard

The best time to talk about a sports mouthguard is at your child's next routine checkup — before the season begins, not after an injury. Dr. Jae can evaluate your child's bite, check for any existing dental considerations, and recommend the right type of guard for their age, sport, and oral health needs.

If your child plays multiple sports or is in orthodontic treatment, a custom guard is almost always worth the investment. We are happy to walk you through the options and take an impression at the same visit. Book an appointment and we will make sure your young athlete is protected before the next practice.

The Bottom Line

A mouthguard is one of the simplest, most affordable ways to protect your child from a painful and expensive dental injury. Given how active Orange County kids tend to be year-round, it is protective gear that belongs in every equipment bag — right next to the helmet and the water bottle.
