Let’s be real—your teeth aren’t just for selfies and sandwich destruction. They’re vital, and protecting them should be a no-brainer. But when it comes to gear like night guards and sports mouthguards, confusion is common. They might look similar, but trust us, they’re in different leagues.
This guide breaks down exactly what each guard is, what it’s for, and how to choose the one that won’t just sit unused in your bathroom drawer. Whether you’re waking up with jaw pain or gearing up for your weekend warrior moments, knowing the difference could save your smile—and your wallet.
TLDR – Quick Guide
- Night Guards: Custom-made trays to prevent damage from teeth grinding (a.k.a. bruxism) or jaw clenching during sleep.
- Sports Mouthguards: Protective gear worn during contact sports to absorb impact and prevent oral injuries.
- Main Difference: Night guards are for nighttime tooth protection from grinding; sports mouthguards are for physical impact during activity.
- Fit & Material: Night guards are thinner and focus on comfort over impact protection. Sports mouthguards are thicker and built to absorb shock.
- Use Case: If you grind your teeth at night, go for a night guard. If you’re playing sports—especially high-contact ones—you need a sports mouthguard.
Detailed Breakdown
What is a Night Guard?
Night guards (also called occlusal guards) are custom-fitted oral appliances worn while you sleep. Their job? Shield your teeth from the grinding, clenching, and gnashing that happens when your brain’s busy dreaming about inbox zero.
Most night guards are made from a softer or dual-laminate material, designed for comfort and to create a protective barrier between the upper and lower teeth. They’re often prescribed to patients dealing with:
- Bruxism (teeth grinding)
- TMJ (temporomandibular joint disorder)
- Morning headaches or jaw pain
Left untreated, these issues can lead to tooth fractures, enamel erosion, and even gum recession.
What is a Sports Mouthguard?
Sports mouthguards are your defense squad on the field or court. Designed to absorb shock and distribute force from a sudden impact, these thicker guards protect the teeth, gums, lips, and even jaw during high-intensity activities.
They’re essential if you’re playing:
- Football, hockey, rugby
- Martial arts or boxing
- Skateboarding or BMX
- Basketball or even soccer
A well-made sports mouthguard can prevent broken teeth, lacerations, and concussions.
Fit and Material Differences
Here’s where it gets technical (but still cool). Night guards are typically thinner and cover only the biting surfaces of the teeth. They focus on alignment and comfort during unconscious movement.
Sports mouthguards are bulkier, often multi-layered, and cover the full dental arch. Their job is to absorb and deflect heavy impact.
Bottom line: one is designed for impact from within, the other for impact from outside.
Can You Use One for Both?
Nope. Using a sports mouthguard for sleeping might feel like trying to nap with a football in your mouth. It’s uncomfortable and ineffective for grinding. On the flip side, using a night guard for sports? That’s a fast track to dental injury.
Each guard is built with a purpose—misusing them isn’t just ineffective, it’s potentially dangerous.

Key Takeaways
- Purpose matters: Don’t use a night guard in place of a sports guard—your teeth (and possibly your dentist) will thank you.
- Customization is key: Store-bought options are fine in a pinch, but for true protection and comfort, go custom.
- Wrong guard, real damage: Using the incorrect guard can lead to broken teeth, TMJ issues, and a painful dentist bill.
- Both may be necessary: Some people need both—night guard during sleep, mouthguard on the field.
- Talk to your dentist: A professional fit and recommendation ensures you’re not winging it with your oral health.
FAQs
No. Sports mouthguards are bulkier and designed for impact, not grinding. Wearing one at night could be uncomfortable and ineffective for preventing bruxism damage.
If you wake up with jaw pain, headaches, or notice your teeth are wearing down or cracking, you might be grinding your teeth. A dentist can diagnose bruxism and fit you with a night guard.
They can offer temporary relief, but they often lack the fit and durability of custom options. For long-term use, especially with heavy grinding or intense sports, a custom-fit guard is much safer and more effective.
Custom guards can last several years if cared for properly, but they should be checked regularly. Over-the-counter or boil-and-bite guards may need replacement every 6–12 months depending on usage and wear.
No. Night guards should be cleaned daily with gentle soap and a soft brush, then stored dry. Sports mouthguards may require more frequent disinfecting, especially after games, to avoid bacterial buildup.
