Night Guard St. John's: Stop Teeth Grinding Now
If you wake up with a sore jaw, dull morning headaches, or a partner who complains about grinding noises in the night, there is a good chance bruxism is the problem. Bruxism, the clinical term for teeth grinding and clenching during sleep, affects a significant portion of the population. Research cited by the Sleep Foundation estimates that roughly 8% of middle-aged adults grind their teeth during sleep, and the condition is even more common among younger people. Left untreated, it quietly destroys enamel, fractures restorations, and strains the jaw joints. A custom night guard in St. John's, fitted by a dentist who knows your bite, is one of the most direct and effective ways to protect your teeth from this kind of invisible damage.

What Is Bruxism and Why Does It Happen?
Bruxism is not a nervous habit you can simply decide to stop. It is an oral parafunctional activity, meaning it is entirely unrelated to normal functions like eating or speaking. Most people who grind their teeth during sleep have no idea it is happening, which is exactly what makes it so damaging over time.
The causes are genuinely multifactorial. Stress and anxiety are consistently identified as the most prominent triggers. Some research suggests that a substantial proportion of bruxism cases are linked to stress or anxiety as an underlying driver. Beyond stress, contributing factors include obstructive sleep apnea, certain medications (particularly some antidepressants and stimulants), alcohol use, smoking, and fatigue. Bruxism is now understood as a condition that originates in the central nervous system rather than in the mechanics of the mouth itself, which is why simply adjusting your bite does not cure it on its own.
For families in St. John's, the combination of seasonal changes, shift work common in the region, and the everyday pressures of family life can all contribute to elevated stress levels. That stress often shows up first in the jaw, and the teeth pay the price.
Bruxism is a sleep disturbance that originates in the central nervous system. The forces generated during grinding episodes can far exceed those produced during normal chewing, making protective intervention a priority rather than an option.
Quick Takeaways
Key Insight
Explanation
Bruxism often goes unnoticed
Most people who grind at night are unaware of it. A dentist typically identifies the signs during a routine examination through patterns of tooth wear.
A custom night guard protects, it does not cure
A night guard acts as a barrier between upper and lower teeth, absorbing grinding forces so enamel and restorations do not. It does not stop the grinding reflex itself.
Over-the-counter guards carry real risks
Poorly fitted guards can shift teeth, irritate soft tissue, and even present a choking hazard during sleep. A dentist-fitted guard eliminates these risks.
Stress management matters alongside the guard
Since stress is the leading driver of bruxism, pairing a night guard with stress-reduction habits produces better long-term outcomes than the guard alone.
Custom guards last significantly longer
A professionally fitted hard acrylic night guard typically lasts between one and five years with proper care, making it far more cost-effective than repeatedly replacing cheap drugstore alternatives.
Sleep apnea and bruxism often co-occur
If you also snore or feel unrefreshed after sleep, mention it at your dental appointment. Both conditions may need to be addressed together.
Your existing dental work is at risk
Crowns, veneers, bridges, and fillings are particularly vulnerable to grinding forces. A night guard is one of the most important investments you can make to protect that existing restorative work.
Signs You Grind Your Teeth at Night
Recognizing bruxism early is the difference between minor intervention and extensive restorative work. The challenge is that sleep bruxism produces symptoms you feel during the day but cannot directly observe at night.
Physical Symptoms to Watch For
The most common morning indicators include a dull, persistent headache concentrated at the temples, jaw muscle fatigue or soreness, and a feeling of tightness or locking in the jaw when first waking up. Some people notice their teeth feel increasingly sensitive to temperature, which is often a sign that enamel has been worn thin.
During a dental examination, a trained dentist will look for abnormal tooth wear patterns, flattened or chipped tooth surfaces, and indentations on the tongue or inner cheek. These are reliable clinical signs that grinding forces are at work even when the patient reports no awareness of it.
When a Partner Notices It First
In many cases, a bed partner is the first to raise the alarm, reporting audible grinding or clicking sounds during sleep. If someone has told you they can hear you grinding, treat it seriously. Audible grinding sounds are a strong indicator of moderate to heavy bruxism, and the sooner a protective appliance is in place, the less damage accumulates.
Pro tip: If you wake up frequently with jaw soreness or headaches, mention it explicitly at your next dental appointment at Stavanger Dental, even if you are coming in for a routine cleaning. These symptoms can be easy to dismiss but they are worth catching early.


Custom Night Guard vs. Over-the-Counter Options
The drugstore aisle sells a version of a night guard, and the price difference compared to a dentist-fitted appliance is tempting. But the comparison is not as straightforward as cost alone suggests, and for most patients with genuine bruxism, the cheaper option tends to create new problems.
Feature
Custom Dentist-Fitted Night Guard
Over-the-Counter (Drugstore) Night Guard
Fit accuracy
Made from precise impressions of your teeth, fits exactly
Generic sizing; boil-and-bite attempts at fit but remains approximate
Comfort during sleep
High, because it does not shift or create pressure points
Often bulky, may feel loose or tight, interrupting sleep
Protection level
Appropriate thickness and material chosen based on grinding severity
One-size protection that may be insufficient for moderate to heavy grinders
Risk of dental harm
Very low when properly fitted and maintained
Poor fit can shift teeth, irritate soft tissue, or misalign the bite
Durability
Typically 1 to 5 years with proper care
Months, often less for heavy grinders
Dentist oversight
Included, checked at regular appointments
None, problems go undetected
A study referenced in the British Dental Journal found that night guards purchased online are associated with tissue damage and teeth movement, and may even present a choking hazard. The conclusion is clear: over-the-counter and online options may look like a bargain, but they carry risks that a custom appliance does not. For patients in St. John's who already have crowns, veneers, or implants, the stakes are even higher. Those restorations represent a significant financial investment, and a poorly fitting guard can undo them.
Pro tip: If budget is a concern, ask the team at Stavanger Dental whether your night guard may be covered under your dental benefits plan or the Canadian Dental Care Plan. Coverage varies, but it is always worth checking before you assume the full cost is out of pocket.
What to Expect from a Night Guard Fitting at Your Dentist
The process of getting a custom night guard is straightforward and comfortable. Understanding each step helps set realistic expectations and removes any hesitation about booking the appointment.
The Initial Assessment
The appointment begins with an examination of your teeth, bite, and jaw muscles. Your dentist will look for signs of wear, assess the severity of the grinding, and check for any related conditions like temporomandibular joint (TMJ) tenderness. This step also determines what type and thickness of guard material is appropriate for your specific pattern of bruxism.
Impressions and Fabrication
Dental impressions are taken of your teeth, and a precise mold is sent to a dental laboratory. The lab fabricates the guard from high-quality acrylic or a dual-laminate material, depending on whether you are a light, moderate, or heavy grinder. This is not a generic process. The material selection matters, and a dentist who knows your case will make better recommendations than any online quiz.
The Fitting Appointment
When the guard is ready, you return for a fitting. The dentist checks the fit against your teeth and makes any needed adjustments to ensure there are no pressure points and that the guard does not affect your bite. You should leave with a guard that feels secure, even, and unobtrusive enough to sleep in comfortably.
If you are also interested in other treatments available at Stavanger Dental, such as orthodontic treatment or restorative procedures, discuss these at the same appointment. Bruxism interacts with both, and coordinating care under one treatment plan makes a meaningful difference.

Caring for Your Night Guard So It Lasts
A custom night guard is an investment. How you maintain it determines whether it lasts one year or five. The basics are not complicated, but skipping them consistently shortens the life of the appliance and creates hygiene problems.
Daily Cleaning Routine
Rinse the guard with cool or lukewarm water immediately after removing it each morning. Clean it with a soft toothbrush and mild soap, not toothpaste, which is abrasive enough to scratch the material. Allow it to air dry completely before storing it in its case. Moisture trapped inside a closed case promotes bacterial growth.
Weekly Deep Cleaning
Every one to two weeks, soak the guard in a denture cleaner, a diluted white vinegar solution, or a mixture of water and baking soda for a deeper clean. Avoid hot water entirely. Heat warps acrylic and can permanently change the fit of a guard that was precisely made to match your teeth.
Signs It Is Time for a Replacement
Check your guard weekly for cracks, holes, or warping. Visible damage means the material is no longer absorbing force effectively. A guard that no longer fits snugly, either because of tooth movement or wear-through, is also due for replacement. A common mistake is continuing to wear a damaged guard, assuming it is still doing something. A damaged guard provides incomplete protection and can cause soft tissue irritation.
Bring your night guard to every regular check-up at Stavanger Dental. The team can inspect it for signs of wear, verify it still fits correctly after any dental work, and advise you on timing for a replacement before problems develop.
How Bruxism Interacts with Crowns, Veneers, and Implants
This is the section that most articles leave out, but it is genuinely important for anyone with existing dental restorations. Bruxism and restorative dentistry are in direct conflict unless you are wearing a properly fitted night guard.
Porcelain veneers are particularly vulnerable to grinding forces because porcelain, while hard, is also brittle under repetitive lateral stress. Grinding sideways across a veneer night after night can chip or crack it far sooner than it should ever need replacing. The same applies to all-ceramic crowns and dental implant restorations. Implants are anchored firmly in the jaw, which means the grinding forces that would normally be distributed through the natural ligament around a tooth are instead transferred directly to the implant fixture and the bone around it. Over time, this can compromise implant stability.
If you are planning dental implants, crowns or bridges, or cosmetic procedures like veneers at Stavanger Dental, a frank conversation about bruxism should happen before treatment begins. In many cases, fitting a night guard before or immediately after restorative work is the responsible approach. Protecting new work from the start costs far less than repairing or replacing it later.
Pro tip: If you have been told you need a crown or are considering veneers, ask your dentist directly: "Is there any sign I grind my teeth?" The answer to that question should influence your treatment plan and the materials your dentist recommends.
Frequently Asked Questions
Can a night guard actually stop bruxism?
No, and it is important to be clear about this. A night guard does not stop the grinding reflex. What it does is absorb and distribute the forces generated by grinding so that your teeth, enamel, and restorations are not the surfaces taking the damage. Think of it as protective equipment rather than a cure. Managing the underlying causes, particularly stress, is the best path toward reducing grinding frequency over time.
How do I know if I need a soft or hard night guard?
The type of guard depends on the severity of your grinding. Soft guards are typically recommended for mild bruxism, while hard acrylic or dual-laminate guards are better suited for moderate to heavy grinders. Your dentist makes this determination after examining your wear patterns and bite. Choosing the wrong material on your own is one of the main problems with over-the-counter options, where you are guessing rather than getting professional guidance.
Is teeth grinding related to sleep apnea?
There is a recognized association between sleep bruxism and obstructive sleep apnea. The two conditions can co-occur, and in some cases the body may grind as a response to airway restriction during sleep. If you also snore, feel unrefreshed after sleeping, or have been told you stop breathing during sleep, mention this to your dentist. You may need an evaluation for both conditions, and a standard night guard is not an appropriate treatment for sleep apnea on its own.
How long will it take to get used to sleeping with a night guard?
Most patients adapt within two to four weeks. The first few nights may feel unfamiliar, and some people experience mild increased salivation while the mouth adjusts. A properly fitted custom guard is significantly easier to adapt to than an over-the-counter option because it does not shift during sleep or create uneven pressure. If discomfort persists beyond a few weeks, return to your dentist for an adjustment rather than abandoning the guard altogether.
Can children or teenagers wear night guards?
Bruxism is actually more common in adolescents than in older adults, with some estimates placing the rate at around 15% in that age group. Night guards can be appropriate for younger patients, but because the jaw and teeth are still developing and changing, fit needs to be monitored more frequently. At Stavanger Dental, the team sees patients of all ages and can advise on whether a night guard is the right approach for a child or teenager, or whether watchful waiting is more appropriate in a given case.
What happens if I never treat bruxism?
Untreated bruxism is progressive. Enamel does not grow back once it is worn away. Over time, you can expect increasing tooth sensitivity, higher risk of chips and fractures, chronic jaw pain, TMJ dysfunction, and more complex and costly restorative work. Patients who address bruxism early with a night guard, stress management, and regular dental check-ups consistently have better long-term oral health outcomes and lower overall dental costs than those who wait until symptoms become severe.
