Mouthguard or nightguard? Do you know which one your child needs? The terms are often used interchangeably, but they are not the same. Mouthguards protect teeth during sports and activities, while nightguards defend against teeth grinding and clenching during sleep. Understanding the difference helps you make the right choice for your child’s oral health and safety.
What Is a Mouthguard?
A mouthguard is a device a child wears to protect their teeth, gums, and jaw during sports and physical activities. You will often hear coaches or school athletic programs require them for contact sports like football, soccer, basketball, lacrosse, or hockey. But mouthguards are also useful in activities where a fall could cause a dental injury, such as gymnastics, skateboarding, or martial arts.
The Benefits of Mouthguards:
- Absorb shock and reduce the risk of broken or chipped teeth
- Protect the lips, tongue, and cheeks from cuts during sudden contact
- Help prevent jaw injuries from impact
- Shield braces and orthodontic appliances from damage
Dental injuries in sports are more common than many parents realize. A single accident can result in a chipped tooth, a knocked-out permanent tooth, or even damage that affects a child’s smile for years to come. That is why pediatric dentists and coaches often insist on mouthguards. They do more than protect teeth, they also help prevent injuries to the lips, tongue, cheeks, and even reduce the risk of serious jaw problems.
Children with braces are especially encouraged to wear mouthguards, as even a single accidental hit to the face could not only injure their mouth but also damage the orthodontic work.
- Stock mouthguards: Pre-formed, inexpensive, but often uncomfortable and loose
- Boil-and-bite mouthguards: Softened in hot water and then molded to the teeth, better than stock versions
- Custom mouthguards: Made by a dentist for the best fit, comfort, and protection

What Is a Nightguard?
While mouthguards are used during the day for sports, nightguards are worn while your child sleeps. They are designed to protect teeth from the effects of bruxism, a condition where children unconsciously grind or clench their teeth at night.
Bruxism in kids may go unnoticed at first. Some parents only realize it when they hear grinding noises at night or when their child complains of morning headaches. Over time, this teeth grinding can wear down enamel, increase tooth sensitivity, and put extra strain on the jaw. This can even interfere with the development of permanent teeth if not addressed early.
Signs your child might need a nightguard:
- Teeth that appear flat, chipped, or worn
- Complaints of jaw soreness or pain when chewing
- Headaches in the morning after waking
- Sensitivity caused by enamel wear
How nightguards help:
Nightguards work by creating a protective barrier between the upper and lower teeth, which reduces the pressure caused by clenching and grinding during sleep. By cushioning the teeth, they help prevent long-term damage to enamel and jaw joints. Many children also experience greater comfort when wearing a nightguard, often waking up without the morning pain or headaches that bruxism can cause.
Unlike bulkier sports mouthguards, nightguards are slimmer and designed for comfortable, long-term wear during sleep. Pediatric dentists carefully design them so that kids can rest easily without feeling like something is shifting around in their mouth. With consistent use, nightguards can make a big difference in protecting a child’s developing teeth.
How to Know If Your Child Needs a Mouthguard or Nightguard
Start by looking at your child’s daily activities and dental habits. If your child participates in sports or recreational activities where falls or collisions are likely, a mouthguard is essential. Even one accident without protection can result in a broken tooth or expensive treatment. Kids who play contact sports several times a week benefit the most from custom mouthguards, which fit better and last longer than store-bought versions.
If your child shows signs of grinding, such as worn teeth, jaw pain, or morning headaches, a nightguard may be recommended. Your pediatric dentist can confirm whether it is needed after an exam. Sometimes, grinding is stress-related or linked to jaw alignment, and having a dentist evaluate it early helps prevent more serious problems later.
Some children may need both. For example, a teen who plays basketball and also grinds their teeth at night would wear a mouthguard on the court and a nightguard to bed. While it may feel like extra effort at first, these devices are simple, comfortable, and effective at protecting long-term oral health. Parents often find that once a child gets used to wearing one, it quickly becomes part of their routine.
