Roughly one in three people grind or clench their teeth during sleep, and most of them have no idea it is happening until a dentist points to the evidence: flattened cusps, cracked enamel, and jaw soreness that shows up every morning. If you have been waking up with a stiff jaw or unexplained tooth sensitivity in St. John's, you may already be experiencing the early signs of bruxism. Finding a qualified night guard dentist in St. John's before that damage compounds is not optional, it is time-sensitive. Stavanger Dental provides custom-fitted night guards and bite planes designed specifically around how your teeth meet, not off-the-shelf trays that shift overnight and do more harm than good.

What Is Bruxism and Why Does It Matter in NL
Bruxism is the involuntary grinding, clenching, or gnashing of teeth. It most often occurs during sleep, making it exceptionally difficult to self-diagnose. The Canadian Dental Association estimates that sleep bruxism affects between 8 and 10 percent of the adult population, with prevalence even higher in people who experience chronic stress or use stimulants regularly.
Newfoundland and Labrador has one of the highest rates of seasonal mood disruption in Canada, largely due to limited daylight hours through winter. Stress and sleep disturbances, both of which are linked to elevated bruxism activity, are genuinely common here. That is not a marketing angle, it is a physiological reality that any dentist practicing in this province sees reflected in patient charts every week.
The consequence of ignoring teeth grinding in NL is not just discomfort. Left untreated, bruxism progressively wears down enamel that cannot regenerate, fractures teeth that may require crowns or extraction, and overloads the temporomandibular joint (TMJ) in ways that produce chronic jaw pain, headaches, and referred ear pain. Stavanger Dental treats bruxism as a clinical priority, not a minor nuisance.
Night Guards vs. Bite Planes: Understanding the Difference
Most patients use the term "night guard" as a catch-all, but there are meaningful differences between the appliances a dentist may prescribe. Knowing which one you need depends on your specific bite pattern, the primary source of your symptoms, and whether your issue is predominantly grinding, clenching, or a bite alignment problem that causes both.
What a Night Guard Does
A night guard is an occlusal splint typically worn over the upper or lower arch. Its primary job is to place a physical barrier between your upper and lower teeth so that the force of grinding does not transfer directly to tooth surfaces. The guard absorbs that force instead. A well-made custom night guard is fabricated from hard acrylic or a dual-laminate material, shaped precisely to your dental impressions, and adjusted in-chair so your bite closes evenly across the entire appliance surface.
In practice, the biggest predictor of whether a night guard works is fit. A loose guard will move during sleep, create uneven bite pressure, and can actually aggravate jaw muscle tension rather than relieve it. This is why over-the-counter boil-and-bite guards have a poor track record for patients with moderate to severe bruxism.
What a Bite Plane Does
A bite plane is a flat, rigid acrylic appliance that contacts only the front teeth. It is specifically designed to disengage the back teeth from contact, which neurologically reduces the intensity of clenching activity. Bite planes are often prescribed when the primary symptom is TMJ pain or muscle tension rather than generalized tooth wear. They are also used during orthodontic treatment to prevent back teeth from over-erupting.
Bite planes are not a substitute for night guards in every case, and vice versa. The choice depends on a clinical assessment, not on which appliance the patient has heard about. At Stavanger Dental, every recommendation starts with a thorough examination of your occlusion, jaw function, and wear patterns before any appliance is discussed.
Quick Takeaways
Key Insight
Explanation
Custom fit is not optional for moderate bruxism
Store-bought guards create uneven pressure and often worsen muscle tension over time. A custom appliance from a dentist is calibrated to your exact bite.
Night guards and bite planes serve different purposes
Night guards protect tooth surfaces from grinding wear. Bite planes specifically reduce clenching intensity by disengaging back teeth contact.
Bruxism damage is cumulative and irreversible
Enamel does not regenerate. Wear that accumulates over years may eventually require crowns, veneers, or implants to restore.
Stress is a primary driver in NL populations
Seasonal mood patterns and winter-related sleep disruption in Newfoundland are documented contributors to higher bruxism activity.
TMJ symptoms often overlap with bruxism
Jaw clicking, ear pain, and morning headaches are frequently caused by nocturnal clenching, not separate conditions.
Appliance replacement matters
Most custom night guards last 2 to 5 years depending on grinding severity. Worn-through appliances no longer protect adequately.
The Canadian Dental Care Plan may cover appliances
Stavanger Dental accepts the Canadian Dental Care Plan, which may offset costs for medically indicated occlusal appliances.
Signs You Need a Night Guard
Bruxism rarely announces itself loudly. Most patients dismiss the early symptoms as unrelated problems, and by the time they connect the dots, months or years of damage have already occurred. The following patterns, seen consistently in patients presenting to Stavanger Dental, are reliable indicators that a professional assessment is warranted.
Morning Jaw Pain and Headaches
Waking up with a tight jaw or a dull headache concentrated at the temples is one of the most common presentations of nocturnal bruxism. The masseter and temporalis muscles, which control jaw closure, are among the strongest muscles in the body relative to their size. When they contract repeatedly through the night, they are effectively doing a workout while you sleep, and the soreness the next morning is no different than post-exercise muscle fatigue.
A common mistake patients make is treating the headache with over-the-counter pain medication for months without investigating the cause. If your headaches are consistently worse on waking and improve through the day, bruxism is a very likely culprit.
Visible Tooth Wear or Sensitivity
If your dentist has pointed out that your teeth look shorter or flatter than they should, that is enamel wear, and it does not happen from brushing. Flattened cusps on molars, chipped edges on front teeth, and increased sensitivity to cold are all physical evidence that grinding forces are acting on your dentition during sleep. These changes can appear gradually over years or progress quickly in severe grinders.
Tooth sensitivity that has increased without a clear cause, such as a new cavity or gum recession, deserves a bruxism evaluation at your next appointment.
A Partner Telling You That You Grind
Sleep partners hear the sound of tooth grinding long before the grinder does. If someone sharing your bed has commented on the noise, take it seriously. The grinding that is audible to another person is typically the lateral, sliding type of bruxism that causes the most rapid enamel wear.
Pro tip: Book a bruxism assessment at Stavanger Dental even if you only suspect you grind. A five-minute clinical examination of your wear facets, bite marks on your cheeks, and jaw muscle tenderness can confirm or rule out active bruxism without any guesswork.
How Stavanger Dental Fits Your Appliance
The process of getting a night guard or bite plane at Stavanger Dental is straightforward, but it is not rushed. The clinical outcome depends entirely on the precision of the fit, and that means taking the time to do the impressions, bite registration, and adjustment properly.
The Initial Assessment
Before any impressions are taken, the dentist will examine your teeth for signs of wear, assess your bite relationship, palpate the jaw muscles for tenderness, and evaluate your TMJ function. This step determines which type of appliance is appropriate. A patient presenting with primarily TMJ clicking and muscle pain will likely receive a different recommendation than one with severe tooth wear across multiple quadrants.
This is where Stavanger Dental's approach to personalized treatment plans becomes practically important. There is no single appliance that suits every bruxism patient, and defaulting to a standard upper hard guard for every case produces inconsistent results.
Impressions and Fabrication
Dental impressions are taken of both arches, along with a bite registration to record how your upper and lower teeth relate to each other. These records are sent to a dental laboratory where your appliance is fabricated from medical-grade materials to match your exact anatomy. The turnaround time is typically one to two weeks.
Delivery and Adjustment
When the appliance returns from the lab, you come in for a delivery appointment. The dentist seats the guard, checks it against your bite with articulating paper, and makes any necessary adjustments to ensure even contact across all surfaces. This step is not cosmetic, it is clinically essential. An appliance with a high spot will create a new occlusal interference and can trigger more clenching, not less.
Patients also receive specific instructions on insertion, removal, and cleaning. A follow-up appointment within a few weeks allows the dentist to confirm the appliance is performing as intended and that symptoms are improving.

Comparison of Appliance Types
Understanding the differences between appliance options helps patients have more productive conversations with their dentist. The table below compares the three most common approaches used in bruxism treatment in St. John's and across Canada.
Appliance Type
Best Suited For
Limitations
Custom Hard Acrylic Night Guard
Moderate to severe grinding with enamel wear across multiple teeth. Patients who have fractured teeth from bruxism. Long-term daily use.
Slightly bulkier than soft guards. Requires professional fitting and periodic adjustment. Cost is higher than OTC options but durability is far superior.
Anterior Bite Plane
Patients with primary TMJ pain, muscle tension headaches, or clenching-dominant bruxism. Also used during orthodontic treatment.
Does not protect back teeth from grinding wear if lateral grinding is present. Not appropriate as a standalone solution for severe grinders.
Over-the-Counter Boil-and-Bite Guard
Very mild symptoms only. Short-term stopgap while awaiting a custom appliance.
Poor fit, inconsistent bite contact, tendency to dislodge during sleep, and limited durability. Not recommended for patients with documented TMJ issues or significant wear.
Long-Term Damage from Untreated Bruxism
The data consistently shows that patients who delay bruxism treatment end up spending significantly more on restorative dentistry than those who address it early. A custom night guard costs a fraction of a single dental crown, and bruxism patients who do not wear an appliance are far more likely to need multiple crowns, root canals on cracked teeth, or implants for teeth that fracture below the gumline.
Enamel Loss and Dentin Exposure
Enamel is the hardest substance in the human body, but it has no capacity to regenerate once lost. Bruxism accelerates enamel wear to a rate that normal chewing never could. As enamel thins, the underlying dentin becomes exposed. Dentin is softer, yellower, and far more sensitive. Patients often notice a sudden increase in cold sensitivity and a change in the appearance of their teeth before they realize enamel loss is the cause.
Once dentin is significantly exposed, the options shift from preventive to restorative. Veneers or crowns become necessary not just for aesthetics but to prevent further structural compromise of the tooth.
TMJ Dysfunction
The temporomandibular joint sits just in front of the ear and acts as the hinge and sliding joint for all jaw movement. Chronic clenching loads this joint with forces it was not designed to sustain repeatedly through the night. Over time, this can cause disc displacement, articular surface changes, and chronic pain that extends into the neck, shoulders, and temples.
TMJ dysfunction related to untreated bruxism is one of the more common referrals seen in orofacial pain practices. Stavanger Dental takes a conservative, appliance-first approach before recommending any more invasive intervention, which is consistent with current evidence-based guidelines for TMD management.
Cracked and Fractured Teeth
Craze lines, incomplete fractures, and full cusp fractures are a direct mechanical consequence of the repeated impact forces generated during grinding. A cracked tooth that reaches the pulp requires root canal treatment and a crown. A fracture that extends below the bone level usually results in extraction. Neither outcome is cheap, and neither was inevitable with early intervention.
Pro tip: If Stavanger Dental has already restored a tooth with a crown or large filling, that tooth is at higher risk for catastrophic fracture if bruxism continues unaddressed. Wearing a night guard is especially important for protecting existing dental work.
Caring for Your Night Guard
A night guard is an investment, and how you care for it directly affects how long it lasts and how well it protects you. The following practices are what Stavanger Dental recommends to every patient who receives a custom appliance.
Rinse your guard with cool water immediately after removing it each morning. Do not use hot water, which can warp the acrylic. Brush it gently with a soft toothbrush and a small amount of non-abrasive soap or a dedicated denture cleaner once per day. Avoid toothpaste, which contains abrasives that scratch the acrylic surface and create micro-pits where bacteria accumulate.
Store the guard in its vented case when not in use. Leaving it exposed dries it out and can cause warping over time. Keep it away from pets, who are inexplicably attracted to dental appliances and will destroy one in minutes.
Bring your night guard to every dental appointment at Stavanger Dental so the team can inspect it for wear, check that the fit is still accurate as your dentition changes, and assess whether it needs replacement. Most guards last between two and five years, but severe grinders may wear through an appliance faster. A guard worn through to the point of having holes or rough patches is no longer protecting your teeth adequately.
Frequently Asked Questions
How do I know if I need a night guard or a bite plane?
The determination depends on a clinical examination, not symptoms alone. If your primary complaint is tooth wear and chipped teeth, a full-coverage night guard is usually the correct choice. If your main symptoms are jaw muscle pain, TMJ clicking, or morning headaches without significant visible tooth wear, a bite plane may be more appropriate. At Stavanger Dental, the dentist will examine your wear facets, bite, and jaw function before recommending any appliance.
Does the Canadian Dental Care Plan cover night guards?
Stavanger Dental accepts the Canadian Dental Care Plan. Coverage for occlusal appliances under the plan depends on the specific plan tier, the patient's documented clinical need, and the benefit codes applicable to the appliance prescribed. The front desk team at Stavanger Dental can verify your coverage before treatment so there are no surprises on the day of your delivery appointment.
How long does it take to get a custom night guard at Stavanger Dental?
The process typically involves an assessment appointment, an impression appointment, and a delivery appointment. The laboratory fabrication time is usually one to two weeks. From your first appointment to having the appliance in your hands, most patients complete the process within three to four weeks.
Can I use a night guard I bought at a pharmacy?
For very mild symptoms over a short period, an over-the-counter guard can serve as a temporary measure. For anyone with moderate or severe bruxism, documented TMJ issues, or existing dental restorations, a boil-and-bite guard is not an adequate substitute. The fit is imprecise, the bite contact is inconsistent, and they frequently create new bite interferences. The data on patient outcomes consistently favors custom appliances for clinical effectiveness and durability.
Will a night guard stop me from grinding completely?
No appliance eliminates the neurological drive to grind. What a properly fitted night guard does is protect your teeth and dental restorations from the mechanical damage that grinding causes, and in many patients, the reduction in tooth contact feedback can reduce grinding intensity over time. Managing the underlying contributors, such as stress, sleep quality, and caffeine intake, improves outcomes alongside appliance therapy.
How is Stavanger Dental different from other dental offices in St. John's for bruxism treatment?
Stavanger Dental takes a comprehensive approach that includes assessing the bite, jaw muscles, and TMJ function before selecting an appliance, rather than defaulting to a standard upper hard guard for every case. The practice also connects bruxism management to broader restorative planning, so if your grinding has already caused damage, the treatment plan addresses both protection and repair together. Patients are not passed between separate specialists for what is fundamentally one connected problem.
