Bruxism is the clinical term for clenching or grinding the teeth and can occur during the day or, more commonly, during sleep. Nighttime grinding often goes unnoticed until it produces telltale signs such as morning jaw stiffness, persistent headaches, tooth sensitivity, or broken dental work. Because it happens while a person is unconscious, many patients only learn they grind from a partner’s report or from the visible wear on their teeth.
Several factors contribute to bruxism. Emotional stress and anxiety are frequent triggers, but physical contributors like an abnormal bite, missing teeth, or poorly aligned teeth can increase the risk. Certain sleep disorders and some medications may also play a role, making a thorough evaluation important to identify potential underlying causes.
Left untreated, bruxism can lead to progressive damage: enamel wear, fractured teeth, and strain on the temporomandibular joint (TMJ). Addressing the habit early with targeted interventions helps protect both soft tissues and dental structures and can reduce the likelihood of developing chronic pain or more complex oral health problems.
A night guard is a protective oral appliance worn during sleep that creates a durable barrier between the upper and lower teeth. By preventing direct tooth-on-tooth contact, the appliance reduces the forces transmitted to the enamel and internal tooth structure. This simple mechanical separation is often enough to stop chips, cracks, and accelerated wear that result from nightly grinding.
Beyond protecting teeth, night guards help relieve muscular and joint strain. The device promotes a more neutral jaw position, reducing the intense contractions that cause sore jaw muscles and pressure on the TMJ. Patients often notice less tightness in the morning and fewer tension-type headaches after consistent use.
Night guards also give clinicians a noninvasive, reversible way to manage bruxism while they investigate contributing factors. In many cases, wearing a guard can interrupt the destructive cycle long enough for other therapies—such as bite adjustments, orthodontic treatment, or sleep evaluations—to be planned and implemented if needed.
Over-the-counter night guards are widely available and can provide short-term relief for some people. However, these one-size-fits-all appliances usually sacrifice fit and long-term comfort for convenience. Poorly fitting guards can move during sleep, cause gagging, or fail to distribute biting forces evenly, which may reduce their protective benefits.
Custom night guards made by a dental professional are crafted from impressions or digital scans of a patient’s teeth, resulting in a precise fit that stays stable throughout the night. This tailored fit not only feels more comfortable but also improves function: forces are distributed predictably, and the device is less likely to irritate gums or cause changes in bite alignment.
Material choice is another important difference. Dental laboratories use specialized materials designed to resist fracture, compressive wear, and bacterial buildup. Clinicians can recommend the material and thickness that best match a patient’s pattern of grinding, existing dental work, and comfort preferences.
Ultimately, a custom night guard represents a long-term preventive strategy. For patients who clench heavily or who have restorations at risk, professional fabrication and periodic adjustments provide a safer, more reliable solution than off-the-shelf alternatives.
An effective night guard begins with a comprehensive dental evaluation. During the exam, the dentist will check for signs of grinding, assess the health of the teeth and gums, and look for TMJ dysfunction. This visit helps determine whether a night guard alone is appropriate or if further investigations, such as a sleep study or bite correction, are warranted.
If a custom appliance is recommended, the clinician will capture accurate impressions or perform a digital scan of the arches. These records are used to fabricate a guard that matches the dental anatomy and anticipated jaw movements. When the device is ready, the patient returns for a try-in and minor adjustments to ensure a stable, comfortable fit.
Patients receive clear instructions about daily care and wearing habits. Cleaning typically involves rinsing the appliance after use and storing it in a ventilated case; periodic professional checks allow the dentist to monitor fit, wear patterns, and any changes in the mouth. If the appliance shows excessive wear or no longer fits well, the dentist can recommend repair or replacement to maintain protection.
Most patients adapt quickly to a well-fit night guard. Wearing it consistently as directed is key to preventing damage and relieving associated symptoms. Follow-up visits give the dental team opportunities to refine the fit and address any emerging concerns.
Seek dental evaluation if you notice signs of grinding—such as flattened teeth, tooth sensitivity, jaw pain, or frequent headaches—or if a bed partner reports grinding noises at night. Early assessment helps the dental team identify the severity of bruxism and determine whether a night guard is the most appropriate starting point.
Depending on the findings, treatment may begin with a custom night guard and progress to additional therapies if necessary. For example, patients with bite-related contributors may benefit from restorative or orthodontic care, while those with suspected sleep apnea could be referred for a sleep study. Collaboration between specialists ensures that both the symptom (grinding) and the root cause are addressed.
The goal of treatment is functional protection and symptom relief while working toward long-term solutions. With proper monitoring and a tailored plan, many patients experience meaningful reductions in pain and dental damage, along with improved quality of sleep.

Bruxism is the medical term for chronic jaw clenching and grinding of the teeth, and it commonly occurs during sleep. People who grind their teeth may wake with jaw pain, sore or loose-feeling teeth, and tension-type headaches. Over time, repeated grinding wears down enamel and can lead to chips, cracks, and increased tooth sensitivity.
Left untreated, bruxism can also place excessive stress on the temporomandibular joint (TMJ) and facial muscles, increasing the risk of TMJ-related pain and dysfunction. Identifying the habit early through a dental exam helps prevent progressive damage and preserves long-term oral health. A tailored treatment plan can address both the habit and its consequences to protect the teeth and supporting structures.
A night guard is a removable oral appliance that fits over the teeth to create a protective barrier between the upper and lower arches. By keeping the jaws slightly apart, the appliance reduces direct tooth-to-tooth contact and absorbs the forces generated by grinding. This protective action helps prevent enamel wear, cracks, and chipping while also reducing strain on the jaw muscles and joint.
Beyond protecting teeth, a well-fitted night guard can decrease episodes of jaw muscle hyperactivity and lessen morning soreness and headaches. Because the guard changes how pressure is distributed across the bite, it can reduce the mechanical causes of damage even if the underlying habit persists. Regular dental oversight ensures the appliance remains effective and comfortable as habits or dental conditions change.
Good candidates for a night guard include patients who exhibit signs of bruxism such as worn tooth surfaces, unexplained tooth fractures, morning jaw pain, or frequent headaches. People with an abnormal bite, missing teeth, or dental restorations that are at risk of damage may also benefit from the protective effects of an appliance. Additionally, individuals under significant stress or those with certain sleep disorders may be advised to consider a night guard as part of their care.
Deciding whether a night guard is appropriate requires a comprehensive dental evaluation that examines tooth wear, jaw function, and overall oral health. The dentist will consider lifestyle factors and related conditions to recommend the most suitable type of appliance. When necessary, the night guard is used alongside other therapies to address contributing causes and improve outcomes.
The process for a custom night guard begins with a thorough oral exam and a discussion of your symptoms and medical history. If a guard is indicated, the clinician will take precise impressions or digital scans of your teeth and record how your jaws meet, which helps the laboratory fabricate an appliance that matches your bite. Lab-made guards are crafted from durable, biocompatible materials and are designed to balance protection, retention, and comfort.
At the delivery appointment the dentist will check fit, adjust contact points, and make any fine-tuning needed to ensure comfort and function. Follow-up visits allow the dentist to monitor wear patterns and make modifications as grinding behavior changes. For many patients, a custom appliance offers superior fit and longevity compared with generic options and improves compliance through greater comfort.
The lifespan of a night guard varies depending on the type of material used and the intensity of the grinding habit, but many custom guards last several years with proper care. Harder, professionally fabricated appliances typically resist wear longer than softer, over-the-counter models. Patients who grind heavily or clench forcefully may notice wear patterns sooner and require replacement more frequently.
You should bring your night guard to regular dental visits so the dentist can inspect it for cracks, thinning, or deformation that compromise protection. Signs that it is time for a new appliance include visible damage, changes in fit, or recurring symptoms such as renewed jaw pain or tooth sensitivity. Routine monitoring and timely replacement maintain protection of your teeth and supporting tissues.
A properly fitted night guard can reduce muscle strain and lessen the intensity and frequency of jaw-related pain and tension headaches for many patients. By limiting clenching and redistributing bite forces, the appliance decreases stress on the temporomandibular joint and the surrounding muscles. This conservative, reversible approach is often used as an initial step in managing TMJ-related symptoms.
That said, TMJ disorders have multifactorial causes, and a night guard is one component of care rather than a universal cure. If symptoms persist or worsen, the dentist may recommend additional therapies such as physical therapy, occlusal adjustments, occlusal splints for daytime use, or collaboration with medical specialists. Ongoing assessment ensures treatment is tailored to the underlying condition and patient response.
Custom night guards made by a dental professional are generally superior to over-the-counter, boil-and-bite appliances in terms of fit, comfort, and long-term protection. A custom device is fabricated from impressions or digital scans of your mouth and is adjusted precisely to your bite, which improves retention and reduces the likelihood of movement during sleep. Better fit also lowers irritation and makes it more likely that patients will wear the appliance consistently.
Over-the-counter options can provide short-term relief for some patients but are not tailored to individual occlusion and may wear out quickly or promote changes in bite if not properly monitored. For patients with restorations, significant malocclusion, or severe bruxism, a custom guard is the safer and more predictable choice. Your dentist can help you weigh the benefits and select the appropriate design for your needs.
Daily care for a night guard helps maintain hygiene and extends the life of the appliance. Rinse the guard after each use and gently clean it with a soft toothbrush and mild, non-abrasive soap; avoid hot water and harsh chemicals that can distort the material. Periodically soaking the appliance in a dentist-approved cleaner or a mild denture solution can help remove buildup and reduce odors.
When not in use, allow the guard to dry thoroughly and store it in a ventilated case away from direct heat or sunlight. Bring the appliance to dental appointments so the dentist can inspect it for wear or damage and confirm it still fits properly. Proper care and routine professional checks preserve the guard's protective function and your oral health.
Most patients tolerate a properly fitted night guard without any negative effect on sleep or breathing, and some people experience improved sleep quality as jaw tension and nighttime arousals decrease. Appliances intended for bruxism are designed to be low-profile and to allow normal jaw movement and airway function. During an adjustment period, mild awareness of the device is common but usually subsides as patients adapt.
If you have symptoms of sleep-disordered breathing such as loud snoring or pauses in breathing, inform your dentist and physician before using a night guard. A guard for grinding is not a substitute for treatments aimed at obstructive sleep apnea, and collaborative care may be needed to address both conditions safely. Your clinician will ensure the chosen appliance supports both oral health and overall sleep safety.
Your first visit will include a focused dental exam that looks for signs of bruxism, such as enamel wear, tooth fractures, or tenderness in the jaw muscles and TMJ. The dentist will review your medical and sleep history, discuss your symptoms, and determine whether imaging or further evaluation is necessary. If a night guard is appropriate, impressions or digital scans will be taken to capture the exact shape and relationship of your teeth.
At a follow-up appointment you will receive the fitted appliance, and the dentist will make any adjustments to ensure comfort and proper bite interactions. The office of Chilmark Dental P.C. will provide instructions on use, cleaning, and follow-up care, and you will be scheduled for monitoring appointments to assess fit and effectiveness. Ongoing communication helps the practice tailor the treatment and achieve the best possible outcome for your oral health.
