Introduction
Do you often find yourself waking up with a headache or jaw pain, and choose to ignore it? You might just be ignoring a far bigger problem. Morning jaw pain and unexplained headaches don’t just point to a bad night’s sleep. They are often the first warnings of nocturnal bruxism. Most people remain unaware they clench or grind their teeth until a dentist identifies the extent of the problem: flattened surfaces, micro-fractures, or receding gums.
In this article, we discuss teeth grinding or bruxism, its effects on your oral health, and what you can do to prevent damage to your teeth and jaws.
What Is Teeth Grinding (Bruxism)?
Bruxism is the involuntary clenching or grinding of teeth. It occurs while you sleep, and is usually associated with stress, anxiety and sleep apnea. However, bruxism can also be caused by missing teeth, malocclusion, and as a side effect of certain medications.
The friction caused by rubbing your teeth together can damage them over time and lead to enamel wear. Bruxism also commonly causes a headache and jaw joint pain after you wake up. Over time, the headaches can become debilitating, and the constant stress can cause inflammation of your jaw joint. It can also weaken your teeth and lead to hypersensitivity.
What Is a Night Guard?
A night guard is a proactive dental appliance designed to be worn while you sleep. It acts as a protective, cushioning barrier between your upper and lower teeth. Night guards prevent the teeth from making direct contact and absorbs the force of clenching and eliminates the friction caused by grinding. Night guards are typically made from high-quality, medical-grade plastics.
Depending on the severity of the grinding, they can be hard and durable or slightly softer and more flexible. While they are often confused with sports mouth guards, night guards are specifically designed to be slim enough for comfortable breathing and sleeping over several hours.
Top Benefits of a Night Guard for Teeth Grinding
Investing in a night guard helps preserve your teeth and your overall well-being. Here are some of the primary night guard for teeth grinding benefits:
1. Prevents Costly Tooth Damage
The most immediate benefit is the preservation of your tooth structure. Constant grinding wears down the enamel. Once the enamel is gone, the softer dentin underneath is exposed, leading to extreme sensitivity and an increased risk of decay. A night guard prevents the need for future restorative work like crowns, veneers, or root canals.
2. Reduces Jaw Pain and Tension
Bruxism puts an immense amount of strain on the temporomandibular joint (TMJ) and the surrounding muscles. This often results in “lockjaw,” muscle fatigue, and facial pain. A night guard helps keep the jaw in a more relaxed, natural position, significantly reducing muscle tension.
3. Eliminates Morning Headaches
Many people suffer from chronic morning headaches without realizing the cause is their jaw. The tension from clenching travels up into the temples and the base of the skull. Once you start wearing a night guard, you will notice an immediate improvement in your symptoms. The reason is, the immense pressure is immediately alleviated by the night guard.
4. Better Sleep Quality
It is difficult to reach deep, restorative sleep when your body is physically stressed and your jaw muscles are working overtime. A night guard allows your muscles to relax, leading to a more peaceful night’s rest for both you and your partner (who will no longer be kept awake by the sound of grinding).
Custom Night Guard vs Store-Bought: Which Is Better?
When looking for teeth grinding treatment in Calgary, you will most probably notice two main options: over-the-counter (OTC) kits and professional custom-made guards.
Store-Bought (Boil-and-Bite) Guards
These are readily available at most pharmacies. You soften the plastic in boiling water and bite down to create a mold.
Pros: Inexpensive and immediate.
Cons: They are often bulky, making them uncomfortable to wear. Because they aren’t perfectly fitted, they can shift during the night or even cause your bite to change over time, potentially worsening TMJ issues.
Custom-Fit Night Guards
Created by your dentist using a precise digital or physical impression of your teeth, these are designed specifically for your unique bite.
Pros: They are much thinner and more comfortable, meaning you are more likely to actually wear them. They are made from superior quality materials that last much longer and are adjusted to ensure your jaw sits in the healthiest possible position.
Cons: Higher initial cost.
For long-term health, the consensus among dental professionals is that a custom guard is a far better investment.
Cost of a Night Guard in Calgary
The cost of a night guard in Calgary typically reflects the professional care and high-quality materials involved in the process. Generally, a custom night guard can range from $400 to $800. In Alberta, dental fees are guided by the provincial fee guide, though individual clinics may vary based on the complexity of the case and the materials used (e.g., a hard acrylic guard vs. a dual-laminate guard).
Many dental insurance plans cover between 50% and 80% under “Major Restorative” or “Basic Services” categories. It is always best to have your dental office send an estimate to your insurance provider to find out exactly what your out-of-pocket expense will be.
How Long Does a Night Guard Last?
A high-quality custom night guard typically lasts between 5 and 10 years. Ultimately, it depends on the intensity of your grinding and how well you care for the appliance. OTC guards, by comparison, often need to be replaced every few months as the thinner plastic is quickly chewed through.
How to Care for Your Night Guard
Here are some practical tips to maintain your custom night guard to make them last for a long time:
- Rinse immediately: Rinse it with cool water as soon as you take it out in the morning to remove saliva and plaque.
- Brush gently: Use a soft toothbrush and non-abrasive soap (avoid toothpaste, as it can scratch the plastic and lead to bacteria accumulation).
- Keep it dry: Always store your guard in a ventilated case to prevent mold and bacterial growth.
- Deep clean: Once a week, use a denture cleaner or a mixture of vinegar and water to deep clean the appliance.
- Bring it to checkups: Always bring your night guard to your regular dental cleanings so your dentist can check for wear and ensure it still fits correctly.
Signs You Need a Night Guard
Since bruxism usually happens when you sleep, many people don’t realize they are grinding their teeth until the symptoms start to show.
If you aren’t sure if you are a “grinder,” look for these common indicators:
- Waking up with a dull headache or earache.
- Increased tooth sensitivity to hot or cold.
- Flattened, chipped, or cracked teeth.
- Indents on the side of your tongue (scalloped tongue).
- Tight or tired jaw muscles.
- Popping or clicking sounds in the jaw joint.

FAQs
1. Do night guards stop teeth grinding completely?
No, nightguards don’t stop teeth grinding. Teeth grinding occurs due to stress, anxiety, sleep apnea or dental anomalies. Night guard protects you by creating a cushion between your teeth.
2.Is it safe to wear a night guard every night?
Yes, it is highly recommended. Consistent use is the only way to ensure your teeth are protected every time you sleep. Most custom guards are designed for long-term, nightly use.
3. How much does a night guard cost in Calgary?
Prices generally fall between $400 and $800. The total depends on your insurance coverage and the specific type of guard required for your level of bruxism.
4.Can a night guard help TMJ pain?
Absolutely. One of the primary benefits of a night guard is that it reduces the stress on the jaw muscles and joints, which is a leading cause of TMJ pain.
5.Are over-the-counter night guards effective?
While OTC nightguards provide a basic physical barrier, they are often too bulky for long-term comfort and lack the precise fit needed to protect your jaw alignment. They are okay for occasional use, but for chronic bruxism, custom night guards are the way to go.
Conclusion
Teeth grinding or bruxism is a common condition that affects many people. However, it might go unnoticed until there’s noticeable discomfort, since this condition usually happens when you sleep. The long-term consequences of untreated bruxism include tooth loss, chronic pain, and expensive dental repairs. They far outweigh the initial cost of a protective appliance. If you notice persistent headaches, jaw pain, or visible tooth wear, don’t wait until it gets worse.
