If you wake up with jaw pain or headaches, it could be due to grinding your teeth at night. This condition is known as sleep bruxism and affects approximately 10-15% of adults. Stress, anxiety, misaligned teeth, certain medications, and disorders like sleep apnea can all contribute to nighttime grinding. With a force of up to 250 pounds — far more than normal chewing — grinding damages tooth enamel, causes jaw pain, and creates other oral health problems. As dental professionals, we’re here to help you recognize the signs and determine whether a night guard could be the best solution to protect your smile.
Common Signs of Nighttime Teeth Grinding
How can you tell if you grind your teeth while you sleep?
Sleep bruxism often goes unnoticed until symptoms appear. Here are some common warning signs to watch for:
-
Morning headaches, especially near the temples
-
Jaw soreness or facial pain upon waking
-
Worn-down, flattened, or chipped teeth
-
Heightened tooth sensitivity
-
Disturbed sleep—either for you or a partner who hears the grinding
-
Cuts or sores on the inside of your cheeks
Catching these signs early can help prevent serious dental damage. If any of these sound familiar, it’s a good idea to schedule a dental checkup.
How Night Guards Protect Your Teeth
Night guards form a protective barrier between your upper and lower teeth. Made from durable plastic or acrylic materials, these oral appliances absorb grinding forces and prevent direct tooth-to-tooth contact.
As dental professionals, we recommend custom-fitted night guards over store-bought options because they provide superior protection, comfort, and longevity. Custom guards match your exact dental anatomy, distribute pressure evenly, and stay securely in place throughout the night.
Types of Night Guards Available
Night guards come in several varieties. Soft night guards are comfortable and work best for mild grinders, but they only last 1-3 years with proper care. Dual-laminate night guards last 3-5 years and feature a soft inner layer and hard outer layer, providing a good balance of comfort and durability for moderate grinding.
With a lifespan of 5+ years, hard acrylic night guards offer maximum protection for severe grinders. However, they’re less comfortable than other types and often require a longer adjustment period. Your dentist will recommend the most appropriate type based on your grinding patterns and severity.
The Custom Night Guard Process
The process of getting a custom night guard starts with a thorough evaluation. Your dentist will examine your teeth, jaw, and bite, and ask about your symptoms and how grinding affects your daily life. To ensure a precise fit, they’ll take either digital scans or physical impressions of your teeth.
These are then sent to a dental lab, where your custom night guard is carefully crafted. Once it’s ready, you’ll return for a fitting appointment to make sure it feels comfortable and fits correctly. Your dentist may schedule follow-up visits to monitor how well the night guard is working and make adjustments if needed, helping you get the most relief and protection possible.
Benefits of Wearing a Night Guard
Consistent night guard use offers numerous advantages. Most obviously, a guard prevents tooth damage by protecting enamel from wearing down and reducing the risk of chips, cracks, and fractures. They also safeguard existing dental work, like crowns and fillings, against grinding damage. By absorbing grinding forces, night guards alleviate jaw pain, morning headaches, and facial muscle fatigue.
Many patients — and their partners — report improved sleep quality without grinding noises and interruptions. Perhaps most importantly, guards help maintain proper jaw alignment and reduce stress on the temporomandibular joints (TMJ), preventing temporomandibular disorders (TMD). From a financial perspective, a night guard costs significantly less than treating extensive dental damage from untreated grinding.
Proper Night Guard Care and Maintenance
Proper maintenance extends your night guard’s life and keeps it hygienic. Rinse with warm (not hot) water before and after each use, and brush gently with a soft toothbrush daily. Do not use toothpaste when brushing, since its abrasiveness could cause premature wear. Let dry completely, then store it in its case.
Perform a deep clean no less than once per month. Weekly is ideal. Soak your nightguard in white vinegar for 30 minutes. Rinse with warm water, then soak your night guard in hydrogen peroxide for an additional 30 minutes. Rinse and let dry completely. Alternatively, you can soak your night guard in a non-abrasive denture cleaner. Regardless of your preferred option, never soak your guard for over an hour.
Keep your guard away from hot water and direct sunlight, which can cause warping. Bring your night guard to dental appointments for professional cleaning, and replace it when signs of wear appear. Store it in its case in a cool, dry area when not in use. Pets seem to love using night guards as chew toys, so be sure to keep it in an inaccessible location if you have furry family members.
Lifestyle Changes That Help Reduce Grinding
Several daily habits help reduce the severity of teeth grinding. Practice jaw relaxation exercises throughout the day to train your muscles to stay relaxed at night. Limit caffeine, especially in the afternoon and evening, as stimulants can increase muscle activity during sleep. Also, reduce alcohol consumption, as it disrupts sleep patterns and can worsen grinding. Establish a consistent sleep routine with adequate time for relaxation before bed. Finally, be mindful of daytime clenching — many people unconsciously clench their teeth during focused activities or stressful situations.
When to Replace Your Night Guard
Even with excellent care, night guards eventually need replacement.
If you notice any of the following, you may need to replace your night guard:
- Visible cracks or holes
- Wear spots or thinning
- Warping or changes in shape
- Persistent bad odor despite cleaning
- New or worsening discomfort
Changes in your bite or new dental work may also require an updated guard design.
The Long-Term Outlook for Teeth Grinders
With proper treatment and consistent night guard use, most people with bruxism can prevent serious dental damage and manage symptoms effectively. Regular dental check-ups allow for monitoring of grinding patterns and adjusting treatment as needed.
Many patients find that their grinding decreases over time with stress management and improved sleep habits, though others may need to use a night guard indefinitely. The good news is that with proper protection, even lifelong grinders can maintain healthy, beautiful smiles.
Working Through the Grind
Teeth grinding damages more than just your smile. It affects your overall health and quality of life. A proper diagnosis, followed by wearing a custom-fitted night guard, protects you from the harmful effects of bruxism.
If you suspect you grind your teeth, don’t wait for damage to appear. Schedule a dental appointment to discuss your symptoms and explore night guard options suited to your needs.
