Sports and play are essential parts of childhood, but physical activity carries a real risk of dental and facial injury. A stray elbow, a fall on the playground, or an impact from a ball can quickly lead to chipped or knocked-out teeth, cuts to the lips and cheeks, or damage to developing tooth roots and braces. For growing mouths, even a minor injury can have long-term consequences for dental health and confidence.
Wearing a properly fitted mouthguard acts as a simple, effective barrier that absorbs and redistributes force away from teeth, soft tissues, and the jaw. Beyond protecting individual teeth, a mouthguard can reduce the risk of jaw fractures and concussions by cushioning blows that might otherwise be transmitted directly to the skull. For parents and coaches, prevention with a mouthguard is often the most practical way to avoid complex, stressful dental emergencies.
Children’s physiology also influences risk: smaller jaws, active play styles, and ongoing tooth eruption mean that kids’ mouths change frequently. That makes fit and comfort especially important—an ill-fitting guard can fall out or discourage consistent use. Prioritizing protection helps preserve healthy smiles and lets kids focus on enjoying sports safely.
There are three common categories of mouthguards available: stock (ready-to-wear), boil-and-bite, and custom-made. Stock guards are inexpensive and pre-formed, but they often lack a secure fit and can interfere with breathing or speaking. Boil-and-bite options offer some customization by softening in hot water and allowing the wearer to shape the material around their teeth; they typically provide better comfort and retention than stock guards but still come with compromises.
Custom-made mouthguards are crafted by dental professionals from impressions or digital scans of a patient’s teeth. Because they are made to match a child’s unique oral anatomy, these guards offer superior fit, stability, and protection. They also allow adjustments for children with braces, missing teeth, or restorative work, ensuring protection without compromising the dental appliances already in place.
Choosing between options depends on the child’s age, level of play, and specific dental needs. For organized, high-contact sports or for athletes who wear orthodontic appliances, a custom mouthguard is often the most reliable choice. For casual play, a boil-and-bite guard can provide a reasonable level of protection when used correctly.
The custom mouthguard process begins with a precise impression or digital scan of the child’s teeth, which a dental laboratory uses to fabricate a guard that mirrors the mouth’s contours. This tailored approach ensures even distribution of force across the teeth and better retention during movement. A custom guard also permits control over thickness in key areas—thicker where impact absorption is needed, thinner where comfort and speech are priorities.
Materials used for custom guards are designed for durability and resilience. High-quality thermoplastic or layered vinyl structures are common because they balance cushioning, tear resistance, and a light weight that children are more likely to tolerate. Because the guard is shaped to the child’s mouth, it stays in place without requiring constant adjustment—an important factor for consistent use during practices and games.
In addition to protection, properly made custom guards can improve confidence and performance. When a guard fits well, athletes can breathe and talk more easily, maintain better focus, and move without distraction. For pediatric patients, a comfortable, professional solution also reduces the chance that the guard will be forgotten or neglected between activities.
Mouthguards are recommended for many organized sports and informal activities where falls, collisions, or fast-moving objects are possible. This includes not only traditional contact sports like football, hockey, and lacrosse, but also sports where collisions can occur unexpectedly—soccer, basketball, skateboarding, and gymnastics among them. School or league rules often require mouthguards for certain age groups or divisions, and coaches frequently insist on them as part of basic safety equipment.
Children with braces, space maintainers, or complex dental restorations require particular attention. Orthodontic hardware can create additional risk for soft-tissue cuts and may alter how a mouthguard fits. A custom guard can be designed to accommodate braces safely, protecting both the teeth and the appliances without creating pressure points that cause irritation. Parents should discuss timing with their dental team, since growth and orthodontic adjustments may prompt periodic refitting.
For younger children whose mouths are rapidly changing, regular monitoring is important. A mouthguard that fit well six months ago might become loose or uncomfortable as new teeth erupt or as the jaw grows. Consistent checks—at home before practices and during routine dental visits—help ensure the guard remains effective and that the child is comfortable wearing it without distraction.
Proper care extends the life of a mouthguard and keeps it hygienic. After each use, rinse the guard with cool water and brush it gently with a toothbrush and mild, non-abrasive toothpaste or a soap solution. Avoid hot water, which can warp thermoplastic materials, and never leave a guard in direct sunlight or stored in high temperatures. When not in use, keep it in a ventilated container to allow airflow and to reduce moisture buildup.
Inspect the guard frequently for signs of wear—thinning areas, tears, or changes in shape can reduce protective value and comfort. If a child reports new soreness, difficulty breathing, or looseness, replace or have the guard evaluated promptly. Because children grow and dental work changes over time, replacement is often necessary every year or when major dental milestones occur, such as the transition from primary to permanent teeth or significant orthodontic adjustments.
Bring a mouthguard to dental appointments so your provider can check fit and condition. The dental team can offer cleaning recommendations, advise on safe storage methods, and suggest an appropriate replacement schedule based on the child’s activity level and oral development. Maintaining good routine care helps preserve protective performance and ensures the guard is ready when it’s needed most.
Protecting an active child’s smile is a straightforward step that pays real dividends. A well-fitting mouthguard reduces the risk of dental trauma, preserves orthodontic work, and keeps kids comfortable so they can focus on play and performance. Selecting the right type—especially when braces or ongoing dental treatment are involved—makes a meaningful difference in both safety and comfort.

Active play and organized sports expose children to falls, collisions, and fast-moving objects that can cause chipped or knocked-out teeth, soft-tissue cuts, and jaw injuries. A properly fitted mouthguard acts as a shock absorber, redistributing impact forces away from teeth and soft tissues to reduce the likelihood of acute dental trauma. For growing mouths and children with developing tooth roots, even a seemingly minor injury can lead to complex dental treatment down the road.
Beyond preserving teeth, a mouthguard helps protect orthodontic appliances and reduces the chance of cuts to the lips and cheeks that can occur when braces or wires are present. Consistent use of a mouthguard during practices and games is one of the most practical preventive steps parents and coaches can take to avoid stressful dental emergencies. Prioritizing protection lets children focus on enjoyment and performance without added injury risk.
The three common categories are stock (ready-to-wear), boil-and-bite, and custom-made mouthguards, each offering different levels of fit and protection. Stock guards are inexpensive but often bulky and poorly fitting, while boil-and-bite guards provide some shaping for improved retention but can vary in comfort and durability. Custom-made guards are fabricated from impressions or scans and deliver the most precise fit, superior retention, and consistent protective thickness where it matters most.
Choice depends on the child’s age, activity level, and dental needs; for casual, low-contact play a properly fitted boil-and-bite guard can be serviceable, while organized contact sports or athletes with braces typically benefit from a custom solution. A dental professional can help match the option to the child’s circumstances and advise when a custom guard is the safer long-term choice. Proper fit and consistent wear are more important than brand when evaluating a guard’s protective value.
Custom mouthguards begin with a precise impression or digital scan of the child’s teeth so a dental laboratory can fabricate a guard that mirrors the mouth’s contours and bite relationships. This personalized approach allows technicians to control thickness in critical impact zones while keeping areas near lips and tongue thinner for comfort and speech. Materials used in custom guards are selected for resilience and tear resistance so the appliance withstands repeated use while maintaining cushioning properties.
Because a custom guard matches the child’s anatomy, it stays in place without frequent adjustment and permits better breathing and speech during activity, increasing the likelihood of consistent use. For children with braces, missing teeth, or complex restorations, a custom guard can be shaped to protect both teeth and dental appliances safely. At Children's Dentistry of Morristown we recommend custom guards when long-term protection, comfort, and appliance compatibility are priorities.
Yes—children with braces, space maintainers, or other dental appliances can and should wear mouthguards to protect both their teeth and the hardware from impact damage. Orthodontic appliances increase the risk of soft-tissue injury and can alter how off-the-shelf guards fit, so standard options may need modification to avoid pressure points or displacement. A custom mouthguard is often the preferred choice because it can be designed to accommodate brackets and wires while still providing adequate cushioning.
Timing is important: as orthodontic adjustments are made, the fit can change, so regular evaluation is necessary to maintain protection and comfort. Parents should bring the guard to routine dental or orthodontic visits so the team can assess fit and recommend adjustments or a replacement if needed. Properly designed guards protect the mouth and appliances without interfering with orthodontic progress.
Mouthguards are recommended for any activity where falls, collisions, or fast-moving objects could strike the face, including contact sports like football and hockey as well as soccer, basketball, skateboarding, and gymnastics. School or league rules may mandate mouthguard use for certain sports or age groups, and coaches often require them as part of standard protective equipment. Even during informal play on playgrounds or in neighborhood games, a mouthguard can reduce the risk of sudden dental trauma.
Encourage children to put on their mouthguard before any practice, scrimmage, or game and to keep it in a ventilated case between uses to protect hygiene and shape. Consistent use during all high-risk activities is the best defense against preventable dental injuries. If the child is unsure whether a specific activity warrants a guard, consult your dental team for sport-specific guidance.
Good daily care keeps a mouthguard hygienic and prolongs its useful life. After each use, rinse the guard with cool water and gently brush it with a soft toothbrush and mild, non-abrasive toothpaste or soap; avoid hot water, which can warp thermoplastic materials. Store the guard in a ventilated container at room temperature and keep it away from direct sunlight or high heat sources.
Periodically disinfect the guard with an antiseptic rinse approved for oral appliances or follow your dental team's specific cleaning recommendations. Inspect the guard before each use for tears, thinning, or deformation that could reduce protection, and replace or have it evaluated if you notice any damage. Proper care supports safety and comfort and reduces the risk of bacterial buildup.
Because children's mouths change as teeth erupt and jaws grow, regular inspection is essential to ensure continued fit and effectiveness. Check the mouthguard at home before practices and games for signs of wear, looseness, or visible damage, and ask the child if it feels uncomfortable or interferes with breathing or speech. A guard that fits well today may become too tight or too loose as the child develops, making replacement necessary to maintain protection.
Bring the mouthguard to routine dental visits so the dental team can evaluate fit and recommend replacement intervals based on growth, activity level, and any orthodontic treatment. Many children require a new guard at key dental milestones, such as the transition to permanent teeth or after significant orthodontic adjustments. Proactive monitoring helps prevent gaps in protection during critical developmental stages.
A properly fitted mouthguard can reduce the transmission of forces to the teeth, jaws, and soft tissues, which helps lower the risk of dental injuries and some jaw trauma. While mouthguards are an important part of protective equipment, they are not a guaranteed prevention for all head or brain injuries; concussion risk depends on the nature and location of an impact and the presence of other protective gear such as helmets. Mouthguards are most effective at minimizing oral and facial injuries and at reducing direct force transfer to the jaw.
For sports with high concussion risk, mouthguards should be used alongside helmets, proper coaching, and safety protocols to create a comprehensive protective strategy. Coaches, parents, and young athletes should understand that mouthguards are one component of injury prevention rather than a standalone solution. When choosing protective equipment, prioritize proper fit, compliance, and multi-layered safety measures tailored to the specific sport.
A comfortable, stable fit depends on choosing the right type of guard and confirming accurate sizing for the child’s mouth. For boil-and-bite guards, follow the manufacturer’s heating and molding instructions closely and have the child test fit it to ensure retention without obstructing breathing or speech. For the best long-term comfort and retention, consider a custom-made guard fabricated from dental impressions or digital scans, which conforms to teeth, gums, and bite relationships.
Teach the child to practice wearing the mouthguard during light activity so they become accustomed to speaking and breathing with it in place before competitive play. Check straps, helmet compatibility, and how the guard interacts with mouthpieces in other equipment to avoid displacement during collisions. If the guard causes soreness, frequent looseness, or breathing difficulty, consult your dental team for adjustments or alternatives.
Yes—bringing the mouthguard to dental visits allows the dental team to assess fit, hygiene, and wear patterns as part of routine care. Your provider can examine the guard for thinning, tears, or deformation and advise whether cleaning, reshaping, or replacement is appropriate. Regular professional evaluation helps catch fit issues that may not be obvious during home checks and ensures the guard continues to protect as the child's mouth changes.
Your dental team can also offer practical tips for storage, cleaning, and wear schedules tailored to your child’s activity level and dental development. If orthdontic work or major dental milestones occur, bring the guard so the team can determine whether an updated appliance is needed. The simple step of presenting the guard at appointments supports long-term protection and peace of mind for families.
