Bruxism is the medical term for involuntary clenching and grinding of the teeth. It can occur during the day, but many people experience it most noticeably while asleep, when they have little or no conscious control over jaw activity. Nighttime grinding often reveals itself through morning symptoms such as jaw soreness, headaches, worn tooth surfaces, and a feeling that teeth are loose or sensitive.
Several factors can contribute to bruxism. Stress and anxiety are common triggers, but other contributors include sleep-disordered breathing, an uneven bite, missing teeth, and certain medications. In many cases, more than one factor plays a role, so identifying the most relevant causes for each patient is an important first step toward effective management.
Left untreated, chronic grinding can produce progressive damage to teeth and restorations, strain the muscles that control the jaw, and place abnormal pressure on the temporomandibular joints (TMJ). Because signs of wear and pain are gradual, patients and clinicians should remain vigilant for early indicators so that protective measures can be taken before more extensive dental work is needed.
A night guard is a simple, removable dental appliance worn over the teeth during sleep. Its core function is to separate the upper and lower arches so that tooth-to-tooth contact — the cause of grinding damage — is minimized. By providing a resilient barrier, a night guard helps dissipate forces that would otherwise be transmitted through teeth, fillings, crowns, and the jaw joint.
Beyond protecting tooth structure, night guards reduce muscle strain. When the jaws are cushioned and guided into a safer position, the muscles that power clenching have less opportunity to overwork, which can lessen morning stiffness and tension-type headaches. Some patients also report improvements in sleep continuity once the acute discomfort of grinding is reduced.
Importantly, a night guard is a management tool rather than a cure for the underlying cause of bruxism. It protects dental tissues and decreases symptoms while the clinician and patient address contributing factors, which may include stress management, sleep evaluation, or occlusal adjustments when appropriate.
Night guards are available in several forms, ranging from over-the-counter options to laboratory-fabricated custom appliances. Stock appliances are preformed and ready to wear, while boil-and-bite guards offer a semi-custom adaptation after softening in warm water. Custom night guards are designed and made specifically for an individual’s bite using impressions or digital scans and tend to provide the best combination of fit, durability, and comfort.
The choice of material and design depends on the intensity of grinding and the patient’s dental situation. Soft materials can be comfortable for mild clenchers, but heavier grinders often benefit from firmer acrylic appliances that resist deformation. Your clinician will also consider restorative work such as crowns or implants when recommending a design to ensure proper protection and compatibility.
Because one size does not fit all, a thorough examination and discussion about lifestyle, sleep habits, and symptoms will help determine the most appropriate night guard. Custom appliances typically require fewer follow-ups for fit issues and are easier to maintain over the long term compared with generic alternatives.
The process of obtaining a custom night guard begins with a focused dental evaluation that looks for signs of wear, pain, and contributing dental issues. The clinician will review your dental and medical history and ask specific questions about sleep patterns, stress, and any prior dental work. This assessment guides the choice of design and material.
Next comes the impression or digital scan of your teeth. Many practices now use intraoral scanners to capture a precise 3D model of the bite; alternatively, traditional impressions can be taken and sent to a dental laboratory. The lab then fabricates the appliance to match your bite, ensuring even contact and comfortable coverage of the teeth designated for protection.
When the night guard is ready, you’ll return for a fitting appointment where small adjustments are made to optimize comfort and function. The clinician will check how the guard sits, how it affects the bite, and whether it is achieving the intended separation between dental arches. Initial follow-up visits are common to fine-tune fit and to confirm that symptoms are improving.
Simple daily care will keep a night guard functioning well and help it last. Rinse the appliance after use, gently brush it with a nonabrasive toothpaste or mild soap, and store it in a ventilated case away from heat. Avoid hot water and direct sunlight, which can warp thermoplastic materials and compromise fit.
Inspect the guard periodically for signs of wear, cracks, or changes in fit. If the appliance becomes rough, discolored, or begins to feel loose, bring it to the office so the clinician can assess whether a repair or replacement is needed. Regular dental visits are an opportunity to evaluate the guard and the teeth it protects, ensuring both remain healthy over time.
Patients should also be attentive to changes in symptoms. If jaw pain, headaches, or new tooth sensitivity persist despite nightly use, or if you notice altered bite relationships, schedule a re-evaluation. Effective bruxism care often involves an ongoing partnership between patient and dental team to adjust strategies as needs evolve.
Summary: Night guards are a practical, evidence-based way to limit damage from bruxism and ease the muscular and joint strain that often accompanies nighttime grinding. By choosing the right type of appliance, following a careful fitting process in the office, and practicing consistent maintenance, patients can protect their oral health and improve comfort.

Bruxism is the medical term for involuntary clenching and grinding of the teeth that often occurs during sleep. Multiple factors can contribute to nighttime grinding, including stress, sleep-disordered breathing, an uneven bite, missing teeth, and certain medications. Identifying the most relevant contributors for each patient is important because bruxism is frequently multifactorial.
Because patients are usually unaware they grind while asleep, clinicians look for indirect signs like worn enamel, flattened tooth surfaces, and muscle tenderness. A careful review of medical and dental history, sleep patterns, and daily stressors helps clinicians determine likely triggers. Early recognition allows protective and therapeutic measures to be implemented before significant dental damage or joint problems develop.
Common signs of nocturnal grinding include morning jaw soreness, tension-type headaches, increased tooth sensitivity, and visible wear on tooth surfaces. Some patients also notice ear pain or a feeling of tightness in the jaw muscles, and family members may report audible grinding sounds during sleep. Because symptoms develop gradually, patients may not connect them to bruxism without a dental evaluation.
A dental exam will assess enamel loss, fractured restorations, and mobility that can result from chronic grinding. Clinicians may also evaluate the temporomandibular joints (TMJ) for clicking, restricted movement, or pain and consider screening for sleep-disordered breathing when appropriate. This comprehensive approach helps guide whether a protective appliance or additional therapies are indicated.
A night guard is a removable appliance worn over the teeth during sleep that separates the upper and lower arches to minimize tooth-to-tooth contact. By providing a resilient barrier, the device dissipates occlusal forces and reduces the risk of wear, fractured restorations, and increased tooth mobility. Night guards also help decrease excessive muscle activity, which can reduce morning stiffness and tension-type headaches.
While a night guard manages the mechanical consequences of bruxism, it is not a cure for underlying causes such as stress or sleep disorders. Many patients report improved comfort and fewer disruptive symptoms once a protective appliance is in place, which can indirectly support better sleep continuity. The appliance is best used as part of a broader plan that addresses contributing factors identified during evaluation.
Night guards range from over-the-counter stock and boil-and-bite options to laboratory-fabricated custom appliances made from impressions or digital scans. Stock guards are ready-made and tend to offer the least precise fit, while boil-and-bite devices provide semi-custom adaptation; fully custom guards provide the best fit, durability, and comfort for most patients. Material choice—soft thermoplastics versus hard acrylic—depends on the intensity of grinding and the individual’s dental condition.
A clinician will consider the degree of wear, presence of restorations or implants, and the patient’s symptoms when recommending a design. Patients who are heavy grinders or who have extensive restorative work usually benefit from a firmer, custom acrylic appliance. A personalized discussion about lifestyle, sleep habits, and follow-up needs will help determine the most appropriate option for long-term protection.
The process for a custom night guard begins with a focused clinical evaluation that documents wear patterns, assesses the TMJ and muscles, and reviews medical and sleep history. The clinician then captures the bite relationship using a digital intraoral scan or traditional impressions, which are sent to a dental laboratory that fabricates the appliance to precise specifications. This customized fabrication ensures even contact, comfortable coverage, and a design that protects vulnerable teeth and restorations.
When the appliance is delivered, the dentist performs a fitting appointment to fine-tune contact points and verify comfort and function. Initial follow-up visits may be scheduled to adjust the fit and confirm that symptoms are improving without introducing bite changes. At Suss Dental Group in Bergenfield, clinicians typically emphasize both fit and patient education so the appliance integrates smoothly into the patient’s nightly routine.
Good candidates for a custom night guard include patients with evidence of enamel wear, fractured restorations, tooth sensitivity related to grinding, persistent jaw or muscle pain, and those who have been observed grinding during sleep. Individuals with extensive dental restorations or implants often require a tailored appliance to protect both natural teeth and prosthetic work. Candidates should also be willing to participate in follow-up care so the appliance remains effective over time.
Patients with suspected sleep-disordered breathing or significant daytime symptoms may need a multidisciplinary evaluation before or alongside appliance therapy. In such cases, collaboration with a physician or sleep specialist can identify additional interventions that address the root cause. The decision to proceed with a custom guard is based on clinical findings and shared decision-making between patient and clinician.
The lifespan of a night guard varies depending on material, the intensity of grinding, and how well it is cared for; custom acrylic guards often last longer than softer, over-the-counter devices. Regular inspection for cracks, heavy wear, and fit changes helps detect when repair or replacement is needed, and routine checkups allow your dentist to evaluate both the appliance and the teeth it protects. Avoiding hot water and direct sunlight and storing the guard in a ventilated case prevents warping and premature degradation.
Daily cleaning using mild soap or a nonabrasive toothpaste and rinsing after use will minimize odor and bacterial buildup without damaging the material. Patients should bring the appliance to dental visits so the clinician can make any necessary adjustments and confirm ongoing protection. With proper maintenance and professional oversight, a custom night guard can provide effective service for several years in many cases.
A night guard can reduce muscle strain and the harmful forces transmitted to the temporomandibular joints, which often leads to decreased jaw soreness and fewer tension-type headaches. By cushioning the bite and guiding the jaw away from harmful contact patterns, the appliance reduces opportunities for muscles to overwork during sleep. Many patients experience symptomatic relief, particularly when grinding is a primary driver of their discomfort.
However, TMJ disorders have a range of causes, and a night guard is one component of management rather than a standalone cure. Clinicians evaluate joint function, consider physical therapy or behavioral strategies, and coordinate care with other providers when necessary. If headaches or TMJ pain persist despite appliance therapy, additional diagnostic steps and alternative treatments may be indicated.
Over-the-counter guards and boil-and-bite devices can provide short-term protection for mild clenching, but they generally lack the precise fit and durability of custom laboratory-fabricated appliances. Poor fit can lead to discomfort, changes in occlusion, and inadequate force distribution, which may limit the device’s protective benefits over time. For patients with significant wear, restorations, or heavy grinding, a custom appliance is typically a more reliable long-term solution.
That said, some patients use over-the-counter options as a temporary measure while arranging a custom solution or when symptoms are minimal. A dental evaluation is recommended before relying on any appliance so the clinician can assess the extent of damage and recommend the most appropriate design. Regular monitoring ensures that the chosen device continues to protect oral health effectively.
Schedule a re-evaluation if you notice increased jaw pain, persistent headaches, new tooth sensitivity, rough or cracked areas on the appliance, or a change in how it fits your teeth. Regular dental visits also provide an opportunity for your clinician to inspect the guard, assess wear patterns, and confirm that it is still offering appropriate protection. Prompt attention to fit issues can prevent further dental damage and ensure ongoing symptom relief.
If you experience changes in your bite, difficulty wearing the guard, or recurrent symptoms despite nightly use, contact the office for a follow-up appointment so the clinician can determine whether adjustment, repair, or replacement is needed. In Bergenfield and surrounding communities, patients can rely on the dental team to evaluate evolving needs and recommend next steps to protect oral health. Suss Dental Group encourages patients to maintain open communication so care can be adapted as conditions change.
