Many people unknowingly clench or grind their teeth while they sleep — a condition known as bruxism. For some, the signs are subtle: a stiff jaw upon waking, dull headaches, or increased tooth sensitivity. For others, the consequences can be more obvious, including worn enamel, fractured restorations, and discomfort in the temporomandibular joint (TMJ).
Bruxism is rarely caused by a single factor. Stress and anxiety are common contributors, but sleep-related breathing issues, certain medications, an irregular bite, and missing or misaligned teeth can also play important roles. Lifestyle elements such as excessive alcohol or caffeine intake and poor sleep hygiene may increase the likelihood of nighttime grinding.
Left unaddressed, chronic grinding can accelerate dental wear and lead to costly restorative work down the road. More immediately, it can interfere with restful sleep and daily comfort. Recognizing the early signs and seeking an evaluation can help you protect both your oral health and overall well-being.
A night guard is designed as a protective barrier that separates the upper and lower teeth during sleep. By preventing direct tooth-to-tooth contact, a properly fitted guard reduces the intensity of forces transmitted to the teeth, dental restorations, and the jaw joint. This cushioning effect helps limit enamel loss and reduces the risk of chips and fractures.
Beyond protecting tooth surfaces, night guards can ease muscle tension and lower strain on the TMJ. When the jaw muscles no longer have to absorb the full impact of grinding, many patients experience fewer morning aches and less muscular fatigue. Although a night guard does not cure the underlying cause of bruxism, it is an effective tool for minimizing damage while additional evaluation takes place.
There are several styles of night guards available, from softer, flexible appliances to firmer, more durable designs. The best choice depends on the severity of grinding, bite characteristics, and patient comfort. A dental professional can recommend the most appropriate material and design based on a clinical assessment.
Night guards sold over the counter offer quick access and low upfront effort, but they usually provide a generic fit that can be less comfortable and less effective over time. A custom night guard made from impressions or digital scans conforms precisely to your dental anatomy, improving stability and minimizing unwanted movement during the night.
Because a custom appliance is tailored to the way your teeth come together, it often requires fewer adjustments and lasts longer under normal use. Clinically fabricated guards also allow the dentist to control thickness and occlusal contacts in ways that support healthy jaw function and minimize bite changes.
Comfort matters — if an appliance is bulky or ill-fitting, patients are less likely to wear it consistently. Choosing a custom solution increases the chance that the guard will be worn every night, which is essential for protection and symptom relief.
An initial visit begins with a dental exam and a discussion about symptoms, sleep habits, and any relevant medical history. The dentist will look for signs of wear, cracks, or restorations that may be affected by grinding, and will assess jaw movement and bite relationships to determine the most appropriate appliance.
Many practices now use digital scanning technology to capture precise impressions of the teeth, while others still use traditional putty impressions. Whether digital or physical, accurate records allow the laboratory to fabricate a night guard that fits closely and functions as intended. After the appliance returns from the lab, a fitting appointment ensures proper fit and comfort, and the dentist will make any necessary adjustments.
Follow-up visits are important, especially in the early weeks of wearing a night guard. These appointments let the dentist verify that the appliance is protecting the teeth effectively, address sore spots, and confirm that the guard is not causing unintended bite changes. Long-term monitoring also helps detect any evolving dental or jaw joint issues.
Caring for a night guard is simple but essential. Rinse it after each use, clean it gently with a nonabrasive cleanser, and store it in a protective case away from heat. Avoid hot water and harsh chemicals that can warp or degrade the material. Regular cleaning helps prevent buildup of bacteria and preserves the appliance’s fit and function.
Check your night guard periodically for signs of excessive wear, cracks, or distortion. Some wear is expected over time, but significant damage can compromise protection and may increase the risk of dental problems. Bring your guard to dental visits so the team can assess its condition and make recommendations.
How long a night guard lasts varies by material and the intensity of grinding. With proper care and professional oversight, many patients find their custom guards remain effective for several years. If discomfort, increased grinding, or changes in your bite occur, schedule an evaluation to determine whether an adjustment or replacement is needed.
While night guards are an important first-line strategy for protecting the teeth and relieving symptoms, they are not always a complete solution. If jaw pain persists, clicking or locking of the TMJ occurs, or if there are signs of a sleep disorder, further diagnostic steps may be recommended. These could include imaging, sleep studies, or collaborative care with a sleep medicine specialist or an orthodontist.
Some patients benefit from adjunctive therapies such as stress management, physical therapy for jaw muscles, or targeted dental work to correct bite imbalances. The goal is to identify and address any contributing factors so that protective measures like a night guard are part of a broader, more effective plan.
At Crowns Now Family Dentistry, our dentists evaluate each patient’s unique situation and discuss appropriate next steps when a simple appliance may not be sufficient. We aim to combine protective treatment with a thoughtful diagnostic approach so patients receive care that protects their teeth today and supports long-term oral health.

A night guard is a removable oral appliance worn over the teeth while sleeping to protect against the effects of bruxism, which is the involuntary clenching or grinding of the teeth. The device creates a durable barrier between the upper and lower teeth, reducing direct tooth-to-tooth contact and distributing biting forces more evenly. By preventing hard surfaces from striking each other, a night guard helps limit wear, chipping, and the progression of dental damage.
In addition to protecting tooth structure, the night guard can reduce strain on the jaw muscles and temporomandibular joint (TMJ) by keeping the jaws slightly apart and altering the pattern of muscle activity. Many patients also notice fewer morning symptoms such as sore teeth, jaw discomfort, and tension-type headaches when they use an appropriate appliance. For optimal results, a night guard should be selected and fitted based on a professional evaluation of oral health and bite alignment.
Patients who regularly clench or grind their teeth, have unexplained tooth wear, recurrent enamel fractures, or jaw pain may benefit from a night guard. Signs that something may be damaging your teeth overnight include flattened chewing surfaces, increased tooth sensitivity, and frequent tension headaches upon waking. A dentist will also consider contributing factors such as bite misalignment, missing teeth, or sleep disturbances when determining candidacy.
Evaluation typically involves a clinical exam and, when appropriate, imaging or bite analysis to identify wear patterns and TMJ health. Because underlying causes vary, the decision to provide a night guard is individualized and may be part of a broader treatment plan that addresses orthodontic, restorative, or sleep-related issues. Patients with significant dental restorations, implants, or active periodontal disease should discuss appliance design and precautions with their dentist before use.
The process for a custom night guard begins with a thorough dental exam and impressions or digital scans of your teeth to capture the exact shape of your bite. Those impressions are used to fabricate a laboratory-made appliance from durable materials that match your oral anatomy, ensuring a stable, comfortable fit and appropriate occlusal relationships. A custom approach allows the clinician to control thickness, coverage, and the degree of jaw separation to address each patient’s specific needs.
Once the appliance is fabricated, the dentist performs a fitting appointment to verify comfort, retention, and how the teeth meet while wearing the guard. Minor adjustments are made chairside to eliminate pressure points and to optimize muscle relaxation and joint positioning. The result is a tailored device that is more effective and longer lasting than over-the-counter alternatives for many patients.
Over-the-counter night guards, including boil-and-bite products, provide a generic fit and are made from softer materials that may not offer consistent protection or long-term durability. Custom night guards made from impressions or digital scans are fabricated to closely match your teeth and bite, which improves retention, comfort, and the appliance’s ability to control harmful forces. Because the custom device is designed to manage occlusion, it can help address muscle and joint symptoms more predictably.
Custom appliances also allow dental professionals to select materials suited to a patient’s level of grinding and to adjust the guard over time if needed. While some patients find store-bought guards acceptable for mild habits, those with moderate to severe bruxism, existing restorations, or TMJ symptoms typically benefit more from a professionally made appliance. The dentist will recommend the best option based on clinical findings and long-term oral health goals.
Night guards are intended to be worn throughout sleep during the period when bruxism occurs, which for most people is nightly. Patients often notice initial symptom relief—such as reduced morning jaw soreness or fewer headaches—within days to a few weeks of consistent use, although the timeline varies by individual and the severity of grinding. The appliance works by interrupting grinding activity and protecting dental structures, so consistent nightly use is important for measurable benefit.
Follow-up appointments are recommended to assess fit and symptom improvement and to make any necessary adjustments. If underlying contributors such as sleep disorders or occlusal problems are present, additional treatments or referrals may be needed to achieve full symptom control. Your dentist will help set realistic expectations and monitor progress over time.
A properly fitted night guard can reduce the strain on jaw muscles and the temporomandibular joint, which often leads to a decrease in muscle-related jaw pain and some tension-type headaches. By preventing excessive force and tooth-to-tooth impact, the appliance limits the conditions that provoke muscle fatigue and joint irritation. Many patients report fewer morning aches and an improvement in facial muscle tension after initiating nightly wear.
However, not all headaches or jaw pain are solely caused by bruxism, and some patients may require a multidisciplinary approach including physical therapy, stress management, or evaluation for sleep-related breathing disorders. If pain persists despite wearing a night guard, the dental team will reassess occlusion, joint health, and other possible causes to refine the treatment plan. Ongoing monitoring ensures the appliance is contributing appropriately to symptom relief.
Daily care helps maintain hygiene and extend the life of a night guard: rinse the appliance with cool water after removal, brush it gently with a soft toothbrush and nonabrasive toothpaste or mild soap, and allow it to air-dry before storing. Avoid hot water or harsh chemicals that can deform or degrade the material, and do not leave the guard exposed to direct sunlight. Regular cleaning also helps prevent bacterial buildup and unpleasant odors.
When not in use, store the night guard in its ventilated case away from pets and extreme temperatures. Periodic professional cleaning or inspection at routine dental visits is recommended to check for wear, fit changes, or signs of damage. If cracks, thinning, or persistent odor develop, bring the appliance to your dentist for evaluation and possible replacement.
When properly designed and fitted, a night guard is intended to protect natural teeth and dental work rather than cause harm, but poorly fitting or inappropriate appliances can create problems such as uneven pressure or irritation. It is important that the appliance is tailored to accommodate existing restorations, implants, and the patient’s bite to avoid concentrating forces on a single tooth or component. A comprehensive dental exam prior to fabrication helps identify any special considerations that will influence the appliance design.
The dentist will monitor how the guard interacts with your restorations during follow-up visits and make adjustments as needed to prevent adverse effects. If you notice new discomfort, mobility of a restoration, or changes in how your teeth come together, stop using the appliance and schedule an appointment so that the fit and function can be reassessed. With professional oversight, a night guard is a protective tool for both natural teeth and restorative work.
The frequency of adjustments or replacement depends on the material of the night guard and the intensity of the patient’s grinding habit. Harder, professionally fabricated appliances tend to last longer but still require periodic evaluation for wear, fit, and effectiveness. Regular dental checkups provide opportunities for the dentist to adjust occlusion, smooth rough edges, and confirm that the device continues to protect the teeth and support jaw comfort.
Patients with heavy bruxism may wear through an appliance more quickly and will be monitored more closely to determine the appropriate replacement interval. Keeping scheduled follow-up visits and reporting any changes in symptoms or appliance fit will help ensure timely maintenance and preserve oral health over the long term.
Night guards designed specifically to advance the lower jaw, often called mandibular advancement devices, can reduce snoring and mild to moderate obstructive sleep apnea by enlarging the upper airway during sleep. Standard occlusal night guards for bruxism are not the same as mandibular advancement devices and are not intended to treat sleep apnea. If sleep-disordered breathing is suspected, a dental or medical evaluation, including possible sleep testing, is necessary to determine the correct appliance or therapy.
The dental team can collaborate with sleep medicine specialists to select and fit an appropriate device when indicated, and will monitor dental and jaw health while using any airway-focused appliance. Patients should not assume a bruxism night guard will address snoring or sleep apnea without professional assessment and coordination of care.
