Night Guards

What happens when your jaw won’t rest: understanding bruxism

Many patients are surprised to learn that teeth grinding and jaw clenching — medically known as bruxism — is a common, often unconscious condition. It can occur during the day, but nighttime bruxism is particularly disruptive because it happens while you sleep and may go unnoticed until symptoms appear. Morning jaw tightness, frequent headaches, and teeth that feel sensitive or loose are common signs that grinding may be occurring after you fall asleep.

Bruxism doesn’t have a single cause. Emotional stress and anxiety are frequent contributors, but sleep-related breathing disorders, certain medications, and an uneven bite can also play a role. Genetics and lifestyle factors, such as caffeine or alcohol use, may increase the likelihood of nighttime clenching. Because the reasons can be varied, identifying contributing factors is a key step in managing the condition effectively.

Left unmanaged, bruxism can harm more than tooth enamel. Chronic grinding places sustained pressure on the temporomandibular joints (TMJ), can accelerate wear on restorations, and may lead to muscle fatigue and persistent facial pain. A night guard is one of the most commonly recommended tools to interrupt that cycle and protect oral structures while other diagnostic steps are taken.

How night guards protect your teeth and jaw during sleep

A night guard acts as a resilient barrier between the upper and lower teeth, absorbing the force of clenching and preventing direct tooth-on-tooth contact. By redistributing and dissipating pressure, the appliance reduces the chance of chips, cracks, and progressive wear that can compromise dental health over time. For many patients, this simple mechanical separation delivers immediate relief from the most destructive aspects of grinding.

Beyond protecting tooth surfaces, a well-designed night guard can ease muscle tension and lower the strain on the TMJ. When the jaw is held in a more relaxed position, muscles have a chance to recover overnight, which often reduces morning stiffness and lowers the frequency of grinding episodes. In some cases, this improvement in muscle comfort helps restore healthier sleep patterns as well.

Night guards are not a cure for every underlying cause of bruxism, but they are a practical, noninvasive first-line defense. While the appliance addresses the mechanical damage, clinicians will often pair its use with evaluations for sleep disorders, bite issues, or stress-related triggers to create a more complete care plan.

Choosing between over-the-counter and custom night guards

Night guards are available in several forms, and choosing the right one depends on the severity of grinding, individual comfort, and long-term protection goals. Over-the-counter “boil-and-bite” options provide a quick, low-effort solution for mild clenching, but they may not deliver the fit, durability, or balanced bite alignment that some patients need. They can be a temporary option, but they are less precise than professionally made appliances.

Custom night guards, crafted from impressions or digital scans, are tailored to each patient’s bite and facial anatomy. This custom fit reduces bulk, improves comfort, and ensures the occlusal surfaces interact correctly to minimize harmful forces. Because they are made from stronger materials and designed to match the way your teeth come together, custom appliances generally provide better, longer-lasting protection for those with moderate to severe bruxism.

When deciding between options, clinicians weigh factors such as tooth movement risk, presence of restorations, TMJ symptoms, and how long the patient intends to use the appliance. A personalized assessment helps determine whether a ready-made guard is sufficient or if a custom device is the better investment in oral health and sleep quality.

What to expect during the fitting and adjustment process

A professional night guard fitting begins with a focused examination. The dentist evaluates your teeth, bite relationships, and any signs of wear or joint strain. If a custom appliance is recommended, impressions or a digital scan will be taken to capture the precise contours of your arches. This information guides the lab in fabricating a guard that supports comfortable jaw posture and even contact across the teeth.

Receiving a custom night guard usually involves a brief follow-up appointment to check fit and comfort. A new appliance may feel different at first — some patients notice increased salivation or a slight change in bite — but these sensations commonly diminish after a few nights. The dental team will provide clear instructions on insertion, removal, and nightly wear schedule, and will advise when to return for adjustments if any pressure points or looseness develop.

Long-term success depends on regular monitoring. As your mouth changes with dental work, tooth movement, or natural aging, the fit can be affected. Periodic checks allow the dentist to assess wear, confirm ongoing protection, and make any necessary refinements to keep the appliance functioning as intended.

Daily care, longevity, and broader health considerations

Proper care extends the life of a night guard and keeps it hygienic. Rinse the appliance after each use and brush it gently with a nonabrasive toothpaste or mild soap; avoid hot water and strong chemicals that can deform materials. Store the guard in a ventilated case away from direct sunlight. Regular cleaning helps prevent odors, bacterial buildup, and discoloration while preserving the structural integrity of the device.

The lifespan of a night guard depends on material quality and the intensity of grinding. Some guards show visible wear after months, while others last several years. During routine dental visits, your provider will inspect the appliance for signs of thinning, cracking, or loss of fit and recommend replacement when needed. Timely replacement protects both your teeth and any existing dental work from damage.

Finally, a night guard can be part of a broader strategy to address bruxism. Alongside the appliance, clinicians may recommend sleep evaluations, stress-management techniques, or adjustments to medications when appropriate. If jaw pain, persistent headaches, or new bite changes occur, those symptoms warrant prompt evaluation to rule out other conditions and refine the treatment approach.

Frequently Asked Questions

What is a night guard and how does it help with bruxism?

+

A night guard is a removable oral appliance worn during sleep to protect the teeth and jaw from the effects of bruxism, the habit of clenching or grinding. It forms a barrier between the upper and lower teeth to prevent direct tooth-to-tooth contact and reduce the force transferred to the jaw joints and muscles. By minimizing friction and dampening impact, a night guard helps limit tooth wear, chipped or cracked teeth, and strain on the temporomandibular joint.

In addition to protecting hard dental tissues, a properly fitted night guard can lessen muscle fatigue and associated symptoms such as morning jaw pain and tension headaches. Many patients find that reducing the mechanical damage from grinding also improves sleep quality because the jaw muscles are allowed to relax. A night guard is one component of a comprehensive approach to managing bruxism that may include behavioral strategies and evaluation for contributing factors.

How is a custom night guard different from an over-the-counter appliance?

+

Custom night guards are fabricated from impressions or digital scans of a patient’s mouth and tailored to their bite, while over-the-counter devices are one-size-fits-all and rely on the wearer to mold or trim them. The customized fit improves comfort, retention, and the ability to evenly distribute occlusal forces, which reduces the risk of creating new bite problems or accelerating tooth movement. Because they are designed for an individual’s anatomy, custom guards are typically more durable and effective at protecting teeth and jaw structures.

A custom appliance also allows the dentist to control thickness, material type, and occlusal scheme to address each patient’s clinical needs, such as heavy clenching or a sensitive bite. Custom devices are adjusted chairside to ensure proper fit and function, which reduces soreness and improves long-term compliance. Patients who wear a custom night guard are more likely to report consistent use because the appliance fits well and performs predictably.

What should I expect during the appointment to get a night guard?

+

During the evaluation appointment, the dentist will review your symptoms, examine tooth wear and the health of your temporomandibular joint, and ask about sleep and stress factors that can contribute to bruxism. Impressions or a digital intraoral scan will be taken to capture the exact shape of your teeth and bite, and photos or imaging may be used to document occlusion and any existing damage. This diagnostic step ensures the night guard is designed to address your specific condition and bite relationships.

Once the laboratory has fabricated the appliance, you will return to the office for a fitting where the dentist checks fit, comfort, and occlusal contacts and makes any necessary adjustments. The clinician will instruct you on how to insert, remove, and care for the night guard, and schedule follow-up visits to monitor wear and make further refinements if needed. If symptoms persist or change, additional evaluation may be recommended to explore other contributing factors or alternative therapies.

How long does a night guard typically last and when should it be replaced?

+

Longevity of a night guard depends on the material used, the severity of grinding or clenching, and how well the appliance is cared for, with typical lifespans ranging from one to several years. Hard, professionally fabricated acrylic splints generally last longer than softer thermoplastic appliances but still require periodic evaluation for cracks, thinning, or distortion. Regular follow-up appointments allow the dentist to assess fit and function and to detect signs of excessive wear or damage early.

You should contact the dental office if the night guard becomes uncomfortable, develops sharp edges, feels looser than before, or no longer seems to protect your teeth effectively. Changes in your bite, dental restorations, or tooth movement can alter how the appliance fits and may signal the need for replacement. Routine annual reviews are common so the dentist can recommend a replacement schedule tailored to your situation.

How should I clean and store my night guard?

+

Daily cleaning helps prevent bacterial buildup and prolongs the life of the night guard; rinse the appliance under cool water after removal and brush it gently with a soft toothbrush using nonabrasive, mild soap or a toothpaste recommended by your dentist. Avoid hot water, as heat can warp the material and compromise the fit. For a deeper clean, soak the night guard periodically in a denture-cleaning solution or a product approved by your dental team, following manufacturer guidelines.

When not in use, store the night guard in its ventilated case away from direct sunlight and high heat to prevent distortion and contamination. Keep the case clean and dry, and bring the appliance to dental visits so the clinician can inspect it for wear and hygiene. Never wrap the night guard in tissue or leave it where pets can reach it, and replace the storage case if it becomes cracked or soiled.

Can a night guard help with temporomandibular joint pain or headaches?

+

A night guard can reduce muscle hyperactivity and redistribute occlusal forces, which often relieves muscular pain and tension that contribute to temporomandibular joint discomfort and tension-type headaches. By creating a stable contact pattern and preventing destructive grinding, the appliance helps the jaw muscles relax and decreases episodes of acute strain. Many patients experience a reduction in morning jaw stiffness and fewer tension headaches after consistent use of a properly fitted guard.

However, night guards are one element of a broader treatment plan for TMJ disorders and headache management; diagnostic evaluation is necessary to identify whether joint pathology, disc displacement, or other medical conditions are contributing to symptoms. The dental team will monitor your response and may coordinate care with other healthcare providers if additional therapies, such as physical therapy, occlusal adjustment, or stress-management techniques, are warranted. A tailored approach ensures the night guard supports overall symptom control rather than serving as a sole treatment for complex conditions.

Are night guards comfortable to wear and will they affect my sleep?

+

Most patients adapt to a night guard within a few nights to a couple of weeks, especially when the device is custom-made and properly adjusted to the bite. Initial awareness of an appliance in the mouth is normal and should diminish as you become accustomed to the feel and the slight change in occlusion. Properly designed appliances minimize bulk and interference with the airway, promoting comfort and continued wear during sleep.

If you experience persistent difficulty sleeping, increased gagging, or a sensation that your bite has changed, contact your dental provider so adjustments can be made. In some cases, modifications to thickness, occlusal contacts, or edge contours improve comfort and compliance. Ongoing communication with the dental team helps ensure the night guard supports better sleep rather than disrupting it.

How is a night guard made at the dental office?

+

The process typically begins with a clinical evaluation and then impressions or a digital scan of the teeth to capture precise anatomy and occlusal relationships. These records are used to fabricate a model of the mouth, on which the appliance is constructed using materials chosen for durability and patient needs, such as hard acrylic for heavy grinders or softer materials for gentler protection. Laboratory technicians shape and polish the guard to create smooth margins and a comfortable interface with the soft tissues.

At the fitting appointment the dentist verifies the appliance for fit, retention, and occlusal contacts, making fine adjustments so the guard functions as intended without causing new points of pressure. The clinician will also provide instructions on insertion, removal, and care, and schedule follow-up visits to monitor wear and comfort. At Park West Dental, we emphasize precise fit and patient education to maximize the therapeutic benefit of the night guard.

Can wearing a night guard prevent dental damage and tooth sensitivity?

+

Yes. By preventing the direct contact of upper and lower teeth, a night guard reduces the abrasive and compressive forces that lead to enamel loss, cracked teeth, and restorations failing prematurely. Protecting the occlusal surfaces helps preserve tooth structure and can lessen the progression of dentin exposure, which is often responsible for increased tooth sensitivity. Over time, consistent use of an appropriate appliance can significantly decrease the need for more invasive dental treatments related to grinding damage.

In addition to protecting teeth, night guards can help stabilize the occlusion and distribute biting forces more evenly across the dental arch, which reduces focal stress on weakened teeth. Regular dental examinations will track enamel wear and sensitivity trends so the dentist can adjust the treatment plan as necessary. Preventive maintenance combined with appliance therapy provides a proactive strategy to safeguard oral health.

How do you determine the right type of night guard for a patient?

+

The choice of night guard depends on the patient’s pattern of bruxism, the degree of tooth wear, presence of restorations, jaw joint health, and comfort preferences, all assessed during a clinical evaluation. The dentist considers whether a hard acrylic splint, a dual-laminate design, or a softer thermoplastic guard best addresses the functional demands while protecting dental work and minimizing side effects. Factors such as parafunctional intensity and any history of orthodontic movement or prosthetic restorations also influence material selection and appliance design.

Shared decision-making helps match the appliance to the patient’s needs and expectations, and the selected device is then custom-fitted and adjusted for optimal performance. Follow-up care ensures the chosen night guard continues to meet clinical goals and can be modified if symptoms change. When indicated, the dental team may recommend adjunctive therapies or referrals to manage underlying contributors to grinding or clenching.
