Bruxism is the medical term for repetitive jaw-muscle activity that includes clenching and grinding of the teeth. While some people only experience these movements during waking hours, many unknowingly grind their teeth at night. Because the behavior often occurs during sleep, patients may first notice indirect signs — morning jaw stiffness, headaches that begin near the temples, or tooth sensitivity that wasn’t present before.
Other common indicators include flattened or chipped tooth surfaces, soreness in the face, and interrupted sleep for a bed partner who hears grinding noises. Not every person with occasional teeth contact has a harmful habit; bruxism becomes a concern when it’s frequent, forceful, or associated with discomfort and dental wear. A dental exam can reveal tooth changes and muscle tenderness that point to a chronic pattern.
Recognizing bruxism early helps preserve oral health and prevents longer-term problems. Left unchecked, persistent grinding can contribute to fractures, accelerated enamel wear, and strain on the temporomandibular joint (TMJ). For patients who wake with pain, or whose dentists notice progressive damage, a protective strategy such as a night guard is often recommended as a first-line measure.
Bruxism rarely has a single cause; it often stems from a mix of physical, psychological, and lifestyle factors. Stress and anxiety are frequently implicated because heightened muscle tension increases the likelihood of clenching. Sleep disturbances — including snoring and undiagnosed sleep apnea — can also create arousal patterns that make night-time teeth grinding more likely.
Dental factors play a role as well: an uneven bite, missing teeth, or poorly aligned restorations can alter jaw movement and encourage grinding. Certain medications, caffeine, alcohol, and tobacco may increase the intensity or frequency of bruxism. Age and genetics matter too — children can experience transient bruxism that often resolves, while adults with chronic habits are more likely to sustain dental damage over time.
Understanding an individual’s risk profile is important because it guides treatment decisions. A comprehensive evaluation considers medical history, sleep quality, medication use, and a careful oral exam. When bruxism is linked to other health issues, coordinating care with a physician or sleep specialist can improve outcomes for patients beyond just protecting their teeth.
Night guards are oral appliances worn during sleep to create a protective barrier between the upper and lower teeth. By preventing direct tooth-to-tooth contact, they reduce the mechanical forces that cause enamel wear, chips, and cracks. More than just a shield, a well-designed night guard can also help distribute biting forces more evenly, which lowers stress on individual teeth and dental restorations.
These devices can ease muscle tension by slightly changing the way the jaw closes, decreasing the intensity of clenching episodes. That reduction in muscle strain often translates into fewer headaches and less facial pain upon waking. In addition, a night guard can protect the temporomandibular joint from excessive pressure, which may help prevent or minimize TMJ-related discomfort when used appropriately.
While a night guard doesn’t cure the underlying causes of bruxism, it serves as an effective, conservative tool to limit damage and give patients symptom relief. For many individuals, combining appliance therapy with behavioral measures — such as stress-reduction techniques and sleep hygiene improvements — produces the best results over time.
Night guards fall into two broad categories: over-the-counter (stock and boil-and-bite) appliances and custom-made devices created at a dental office. Over-the-counter options can be convenient and quick to obtain, but they are generic in fit and material. Custom night guards are fabricated from impressions or digital scans of a patient’s teeth, offering a precise fit, improved comfort, and materials selected for long-term wear and performance.
At your dental appointment, the clinician will assess tooth wear, muscle tenderness, and any signs of TMJ dysfunction. If a custom appliance is recommended, the process generally includes an examination, impressions or an intraoral scan, and a try-in to fine-tune fit and occlusion. Modern laboratories and CAD/CAM technology allow for durable appliances made from high-quality acrylics or thermoplastic materials designed for nighttime use.
After the appliance is delivered, your dentist will check for even contact and make minor adjustments to ensure a comfortable bite. Patients typically receive instructions on wear schedule, cleaning, and follow-up. It’s important for patients to report ongoing discomfort or changes in symptoms so the appliance can be modified if necessary; proper fit and patient adherence are key to preventing further dental damage.
For patients with complex dental work, active periodontal issues, or symptoms suggesting a sleep disorder, the treatment plan may include additional evaluations or a multidisciplinary approach. Collaboration with restorative dentists, orthodontists, or sleep medicine specialists can help tailor care so the night guard works as part of a broader strategy to protect oral health and improve sleep quality.
Keeping a night guard clean and in good condition is straightforward but essential. Rinse the appliance each morning and brush it gently with a soft toothbrush using non-abrasive soap or a toothpaste recommended by your dental team. Avoid hot water, which can warp the material, and store the guard in a ventilated case away from direct sunlight. Regular cleaning prevents odor and bacterial buildup, making nightly wear more comfortable and hygienic for patients.
Night guards do wear out over time. How long a guard lasts depends on material, the severity of the grinding, and how well it’s cared for. During routine dental visits, your dentist will inspect the appliance for thinning, cracks, or changes in fit. If the guard no longer provides even contact or becomes uncomfortable, it may need repair or replacement to continue protecting teeth and joints effectively.
Follow-up appointments are also the time to reassess symptoms: persistent jaw pain, new ear or temple discomfort, or worsening tooth mobility warrant a prompt review. If bruxism is accompanied by signs of disrupted breathing during sleep — loud snoring, daytime fatigue, or observed pauses in breathing — your dentist may recommend evaluation by a sleep specialist. Coordinating care helps ensure that patients receive appropriate interventions for both dental protection and overall health.
Night guards are a practical and evidence-based way to reduce the harmful effects of bruxism, protecting teeth and jaw joints while improving comfort for many patients. By combining a clear diagnosis with the right type of appliance and proper follow-up, people who grind or clench their teeth at night can limit dental damage and often experience fewer morning symptoms.

Bruxism is repetitive jaw-muscle activity that includes clenching and grinding of the teeth, often occurring during sleep and sometimes during wakefulness. People commonly notice indirect signs such as a stiff jaw in the morning, temple headaches on waking, or new tooth sensitivity. Because grinding happens during sleep, many patients learn about it from a partner or by recognizing progressive enamel wear on dental exam.
Other physical clues include flattened, chipped, or shortened tooth surfaces and tenderness in the jaw muscles after sleeping. Not every tooth contact is harmful, but frequent, forceful episodes that cause discomfort or dental changes suggest a chronic problem. Early identification allows conservative measures, such as a night guard, to prevent fractures and long-term damage to teeth and the temporomandibular joint.
Bruxism rarely has a single cause and usually reflects a combination of physical, psychological, and lifestyle factors. Stress and anxiety often contribute by increasing muscle tension and the tendency to clench. Sleep disturbances, including snoring and undiagnosed sleep apnea, create arousal patterns that make night-time grinding more likely, and certain medications or substances can increase episode intensity.
Dental factors like an uneven bite, missing teeth, or poorly aligned restorations may also alter jaw movement and encourage grinding. Age and genetics influence risk, with some children showing transient bruxism and some adults developing persistent habits. A full evaluation helps identify contributing factors so care can address both protection and underlying causes.
Night guards are oral appliances worn during sleep to create a protective barrier between the upper and lower teeth and prevent direct tooth-to-tooth contact. By stopping enamel-on-enamel contact, they reduce the mechanical forces that produce chips, cracks, and accelerated wear. A properly fitted guard also helps distribute biting forces more evenly across the dental arch.
Beyond protecting tooth structure, an appliance can decrease muscle strain by subtly changing jaw closure and reducing clench intensity, which often lessens morning headaches and facial pain. Night guards also shield dental restorations from excessive forces and can protect the temporomandibular joint from abnormal pressure. Although they do not cure the causes of bruxism, guards are an effective conservative tool when combined with behavioral and sleep-hygiene measures.
Night guards are commonly available as over-the-counter stock or boil-and-bite devices and as custom-made appliances from a dental office. OTC options are convenient but tend to be bulkier and less precise in fit, which can affect comfort and long-term durability. Custom guards are fabricated from impressions or digital scans and use materials selected for durability and patient-specific function.
The best option depends on the severity of grinding, oral anatomy, and patient comfort; severe grinders and those with complex dental work typically benefit most from a custom appliance. A dentist will consider bite dynamics, existing restorations, and jaw symptoms when recommending a device and can adjust occlusion at delivery. Proper fit and follow-up care are key to ensuring the appliance protects teeth without creating new problems.
During an evaluation for a night guard at the office in Arlington, Virginia, the clinician will review your medical and dental history and ask about sleep and jaw symptoms. The exam includes inspection of tooth wear, assessment of muscle tenderness, and evaluation of the temporomandibular joints and bite relationships. If signs point to bruxism or joint strain, the dentist will discuss the role of an appliance alongside other measures to protect your teeth.
If a custom device is recommended, the process typically involves impressions or an intraoral scan followed by a laboratory or CAD/CAM fabrication and a try-in visit to confirm fit and occlusion. The clinician will make minor adjustments and provide instructions on wear schedule, cleaning, and what to expect during adaptation. Ballston Dental Center emphasizes clear communication and follow-up so the appliance works effectively within an individualized care plan.
Rinse your night guard each morning and brush it gently with a soft toothbrush using non-abrasive soap or a clinician-recommended cleanser; avoid hot water that can warp the material. Daily cleaning removes saliva and debris and helps prevent odor and bacterial buildup that make overnight wear unpleasant. For removable guards, never wrap them in tissues or leave them in a closed, damp environment where mold can grow.
Store the appliance in a ventilated case away from direct sunlight and heat and keep it out of reach of pets, who are often attracted to the smell and can damage it. Bring the guard to routine dental visits so the dentist can inspect it for thinning, cracks, or fit changes that signal the need for repair or replacement. Following these simple steps prolongs the life of the appliance and maintains a hygienic environment for nightly use.
How long a custom night guard lasts depends on the material used, the severity and frequency of grinding, and how well the patient cares for the appliance. Some guards last several years for mild grinders, while heavy bruxers may wear through an appliance more quickly. Visible thinning, cracks, or a change in fit are signs that the device may no longer provide adequate protection.
Your dentist will inspect the guard during regular checkups and recommend repair or replacement when its protective function is compromised or when symptoms change. Prompt attention prevents further tooth damage and avoids placing abnormal stress on the temporomandibular joints or restorations. Keeping a record of changes in comfort and wear patterns helps the clinician determine the optimal timing for a new appliance.
Many patients report decreased morning headaches and less facial pain after starting to wear a properly fitted night guard, because the appliance reduces excessive muscle activity during sleep. By limiting the intensity of clenching, a guard can lower the frequency of muscle spasms that contribute to tension-type headaches. Relief varies among individuals and often improves when appliance therapy is combined with stress-reduction and sleep-hygiene strategies.
A night guard can also reduce abnormal forces on the temporomandibular joint, which may ease TMJ-related discomfort in some patients. However, TMJ disorders have multiple causes and complex cases may require physical therapy, occlusal adjustment, or specialist referral in addition to an appliance. Regular reassessment ensures the guard remains appropriate if symptoms evolve.
Risks or side effects from night-guard use are uncommon but can include temporary jaw soreness, increased salivation, a gagging sensation in sensitive patients, or perceived changes in bite if the device does not fit properly. Ill-fitting OTC appliances are more likely to cause discomfort or uneven contacts that can worsen symptoms. These issues typically resolve after adjustments or by switching to a custom-fitted device made and checked by a dentist.
Patients should report new or worsening symptoms promptly so the appliance can be adjusted or replaced; delaying evaluation can allow dental damage or joint strain to progress. A careful fitting appointment and regular follow-up minimize side effects and optimize therapeutic benefit. When used under professional guidance, the benefits of a night guard generally outweigh the potential downsides.
Consider a sleep specialist referral if bruxism coexists with symptoms suggestive of a sleep-breathing disorder, such as loud, chronic snoring, witnessed pauses in breathing, excessive daytime sleepiness, or morning headaches that persist despite appliance use. Sleep apnea and other sleep disordered breathing conditions can trigger arousals that increase the risk of night-time grinding and may require medical treatment beyond a dental appliance. Because addressing an underlying sleep disorder often improves both overall health and bruxism, coordination between dental and sleep medicine teams can be important, and your dentist may recommend formal sleep testing or a consultation with a sleep physician.
Ballston Dental Center works with medical colleagues when a multidisciplinary approach is needed to treat sleep-related contributors to bruxism and to develop a comprehensive care plan. Treating sleep issues, improving sleep hygiene, and using an appropriately fitted night guard together can lead to better symptom control than any single intervention alone. Prompt evaluation ensures both dental protection and attention to broader health concerns.
