Nightguards vs. Mouthguards: What’s the Difference and Do You Need One?
Many people hear the terms “nightguard” and “mouthguard” and assume they’re the same thing — but they serve very different purposes. Both protect your teeth, but when and why you wear them depends on your specific dental needs.
At Mustang Crossing Dental Care in Forney, we help patients choose the right oral appliance to protect their smiles from damage, whether from grinding, clenching, or sports injuries. Here’s what you should know about nightguards vs. mouthguards — and how to tell which one is right for you.
What Is a Nightguard?
A nightguard (also known as an occlusal guard) is a thin, custom-fitted appliance you wear while sleeping to protect your teeth from bruxism — the medical term for grinding or clenching your teeth.
Over time, bruxism can cause:
Worn or flattened teeth
Jaw pain or stiffness
Headaches, especially in the morning
Cracked or chipped enamel
Tooth sensitivity
A nightguard creates a protective barrier between your upper and lower teeth, absorbing the pressure caused by grinding and helping your jaw muscles relax during sleep.
What Is a Mouthguard?
A mouthguard is designed to protect your teeth and soft tissues (like your lips, cheeks, and tongue) from injury during physical activity.
If you or your child play contact sports such as football, basketball, hockey, soccer, or martial arts, a mouthguard is a must. Even non-contact sports like mountain biking or gymnastics can lead to accidental collisions that cause dental injuries.
Custom mouthguards from your dentist fit more comfortably and securely than over-the-counter versions, providing better protection and breathability.
Nightguard vs. Mouthguard: The Key Differences
| Feature | Nightguard | Mouthguard |
|---|---|---|
| When It’s Worn | While sleeping | During sports or physical activity |
| Purpose | Prevents tooth damage from grinding/clenching | Protects teeth from impact and injury |
| Material | Thinner and designed for comfort | Thicker and designed for impact absorption |
| Fit | Custom-molded to your bite | Custom or store-bought; looser fit if generic |
| Who Needs It | People with bruxism or TMJ symptoms | Athletes or active individuals of all ages |
Both types of guards are made from durable, dental-grade materials, but their functions and designs are specialized for different situations.
Why Custom Guards Are Worth It
While you can buy generic guards at the store, custom-made versions from your dentist offer significant advantages:
Better comfort and fit – Tailored precisely to your teeth for a snug, natural feel.
More protection – Especially important for preventing cracks, chips, or jaw strain.
Longer-lasting – Made from higher-quality materials that resist wear and tear.
Easier to breathe and talk – Especially with sports mouthguards.

Do You Need One?
You may need a nightguard if you:
Wake up with sore jaws or headaches.
Notice flattened, cracked, or sensitive teeth.
Grind or clench your teeth due to stress or sleep issues.
You should wear a mouthguard if you:
Play any sport with physical contact or risk of falls.
Have braces or dental restorations that need extra protection.
Want to prevent costly dental emergencies during activity.
Even if you’re not sure which one you need, your dentist can evaluate your bite and habits to recommend the best solution for protecting your smile.
