Bruxism is the medical term for involuntary grinding or clenching of the teeth. While some people grind during the day, nocturnal bruxism is common and often goes unnoticed until symptoms surface. Many patients first become aware of the habit when they wake with jaw soreness, experience frequent headaches, or notice increased tooth sensitivity. Because grinding happens during sleep, it can progressively damage tooth enamel and dental restorations without the wearer realizing the cause.
There is no single cause of bruxism. Psychological stress and anxiety are frequently implicated, but other contributors include sleep disturbances, certain medications, and bite misalignment. In some cases, missing or poorly aligned teeth change how the jaw closes, increasing the tendency to clench. Because bruxism can be multifactorial, a complete evaluation is important to identify possible triggers and to tailor an effective treatment plan.
Left untreated, nightly grinding can lead to more than just sore muscles. Over time it can wear down tooth structure, produce microfractures in restorations, and put strain on the temporomandibular joints (TMJ). Addressing bruxism early—often with a well-fitted night guard—helps protect oral tissues, reduce muscle fatigue, and prevent the need for more extensive dental work later on.
A night guard is a removable appliance worn over the teeth during sleep to create a protective barrier between the upper and lower arches. By keeping the teeth from contacting each other directly, a night guard limits the harmful forces generated during grinding and clenching. It also positions the jaw to reduce excessive muscle tension, which can ease morning stiffness and decrease the frequency of painful spasms.
Beyond simple separation, the shape and fit of a night guard influence how forces are distributed across the teeth and jaw. A well-designed appliance encourages more balanced muscle activity and prevents abnormal loading on individual teeth or the TMJ. Because each patient’s bite and anatomy are unique, custom-fitted guards tend to offer more consistent protection and comfort than generic over-the-counter options.
Night guards are passive devices: they don’t “cure” bruxism, but they serve as an effective mechanical intervention that mitigates damage while other contributing factors are evaluated. In conjunction with stress management, sleep hygiene, and, where appropriate, dental adjustments, a night guard is often a central element of a comprehensive approach to managing bruxism.
Over-the-counter night guards and boil-and-bite options are widely available and may provide short-term relief for mild grinding. These preformed devices can be convenient and less expensive initially, but they often lack the precision fit and material quality of custom appliances. Improper fit can reduce effectiveness, cause discomfort, or alter the bite in ways that introduce new issues over time.
Custom night guards are fabricated using either a detailed dental impression or a digital scan of the teeth, ensuring a precise fit that conforms to each patient’s bite. These appliances are typically made from durable dental-grade materials selected for comfort and longevity, and they are produced to resist wear while maintaining consistent thickness and support across the chewing surfaces. The result is better protection and typically greater tolerance during sleep.
When choosing between options, clinicians consider the severity of grinding, the presence of dental restorations, and the patient’s long-term needs. For patients with significant wear, multiple restorations, or chronic TMJ symptoms, a custom night guard is usually recommended because it provides superior protection and more predictable clinical results.
Primarily, night guards protect tooth structure and dental work from the repetitive force of grinding. By absorbing and redistributing occlusal forces, they reduce the risk of chips, cracks, and accelerated wear. This protective role is especially important for patients with crowns, bridges, or composite restorations, which can be vulnerable to the concentrated stress of nocturnal grinding.
Night guards also play a role in reducing muscular and joint pain. By limiting intense clenching and helping the jaw assume a more relaxed position, many patients experience fewer headaches and less jaw stiffness. This can improve comfort during the day and contribute to a better overall sense of well-being, particularly for those whose bruxism is stress-related.
It’s important to set realistic expectations: a night guard shields against the mechanical consequences of bruxism, but it is not a standalone cure. Addressing underlying factors—such as poor sleep quality, bite issues, or stress—may require additional medical, dental, or behavioral interventions. A night guard is most effective when used as part of a coordinated plan that addresses both symptoms and causes.
The process begins with a clinical assessment to evaluate tooth wear, joint health, and bite relationships. If a custom night guard is recommended, the clinician will take detailed impressions or a digital scan to create an appliance tailored to the patient’s anatomy. During a follow-up visit, adjustments are made to ensure the guard is comfortable and that it promotes even contact across the bite without causing changes to natural tooth positions.
Adapting to a new night guard can take several nights. Initial sensitivity or awareness of the appliance is normal, and many patients report that discomfort subsides as they acclimate. Consistent nightly use is key to achieving protective benefits; even short episodes of unprotected grinding can contribute to cumulative damage. Patients are typically advised to wear the guard every night unless otherwise instructed by their clinician.
Maintenance is straightforward: rinse the appliance after use, brush it gently with a soft toothbrush, and store it in a ventilated case when not in use. Avoid hot water or harsh chemicals that can deform or degrade the material. Regular dental check-ups include examination of the night guard for wear and fit, and adjustments or replacement can be scheduled when necessary to maintain optimal protection.
If a guard causes persistent soreness, significantly alters how your teeth come together, or begins to collect stains or odors despite routine cleaning, return to the dental office for evaluation. Minor adjustments often resolve fit issues quickly, ensuring continued comfort and effectiveness without interrupting protective coverage.
Consider seeking professional guidance if you experience frequent morning jaw pain, unexplained headaches, increased tooth sensitivity, or visible wear on your teeth. These signs suggest ongoing bruxism that may benefit from intervention. If you notice loose or cracked teeth, or if dental restorations are failing sooner than expected, a night guard can be an important preventive strategy to slow further damage.
Because bruxism can be linked to other health concerns—such as sleep disturbances or chronic stress—a comprehensive evaluation can help identify coexisting issues that influence treatment choices. In some situations, a collaborative approach involving sleep specialists or other healthcare providers is appropriate to address the root causes effectively.

Bruxism is a sleep-related movement disorder in which the teeth are ground or the jaw is clenched involuntarily. Common contributors include psychological stress, disrupted sleep patterns, certain medications, and bite misalignment that alters how the teeth meet. In some patients, missing or poorly aligned teeth change the closing position of the jaw and increase the tendency to clench.
Because bruxism is often multifactorial, a careful clinical evaluation helps identify likely triggers and guide treatment choices. Sleep studies or collaboration with a sleep specialist may be appropriate when grinding is severe or associated with other sleep disturbances. Identifying underlying causes improves the chances of controlling symptoms and limiting long-term dental damage.
A night guard creates a durable barrier between the upper and lower teeth to prevent direct tooth-on-tooth contact during grinding episodes. By absorbing and redistributing occlusal forces, the appliance reduces enamel wear, protects dental restorations, and lowers the risk of chips and fractures. The guard can also encourage a more relaxed jaw posture and reduce excessive muscle tension that contributes to morning soreness.
Night guards are mechanical devices designed to mitigate the consequences of bruxism rather than to cure the underlying condition. When used alongside interventions such as stress management, sleep hygiene improvements, or dental adjustments, a properly fitted guard is often a central component of a comprehensive care plan. Regular monitoring ensures the guard continues to provide effective protection over time.
Over-the-counter and boil-and-bite devices are convenient and inexpensive options intended for short-term or mild use, but they often lack the precise fit and material quality of custom appliances. Poorly fitting OTC guards can be uncomfortable, less effective at distributing forces, and in some cases may alter the bite if they do not conform well to the dental arches. Custom night guards are made from impressions or digital scans and are fabricated from dental-grade materials to ensure consistent thickness and durability.
Clinicians generally recommend custom guards when grinding is moderate to severe, when multiple restorations are present, or when a patient reports TMJ symptoms. Custom appliances are adjusted chairside to achieve balanced contact and comfortable function, which improves tolerance and long-term protection. The choice between options should be guided by clinical findings and the patient’s oral health needs.
Patients who show signs of significant tooth wear, frequent morning jaw pain, unexplained headaches, or increased tooth sensitivity are often good candidates for a custom night guard. Individuals with extensive dental restorations such as crowns, bridges, or composite fillings are also strong candidates, since these restorations can be vulnerable to the concentrated forces of bruxism. Those with chronic TMJ discomfort or a documented history of heavy grinding typically benefit from a professionally fabricated appliance.
A thorough dental examination helps determine whether a custom night guard is the most appropriate intervention and which design will provide optimal protection. At Vernon Woods Dental & Implant Center the clinical team evaluates tooth wear, bite relationships, and joint function to recommend a personalized solution. Collaboration with medical providers may be advised when bruxism appears linked to sleep disorders or systemic conditions.
The fitting process begins with a clinical assessment that documents tooth wear, evaluates TMJ health, and reviews the patient’s dental restorations and bite. If a custom guard is indicated, the clinician will obtain detailed impressions or a digital scan of the teeth to ensure the appliance conforms closely to the dental anatomy. A laboratory fabricates the night guard to the specified design and material, and a follow-up visit is scheduled for fitting and fine adjustments.
During the adjustment appointment the dentist checks contact points, ensures the guard does not interfere with the bite, and modifies any high spots for comfort and function. Patients are given instructions on nightly use, cleaning, and care at the time of delivery. Periodic reassessment allows the clinician to monitor wear and make replacements or refinements as needed to maintain protection.
Adjustment times vary, but many patients report noticeable awareness of the appliance for the first few nights, followed by gradual acclimation over one to two weeks. Initial sensations may include mild increased salivation or a sense of bulk in the mouth, which typically diminishes as the patient adapts. If the appliance produces persistent discomfort, sore spots, or difficulty closing comfortably, a return visit for adjustment is recommended.
Consistent nightly use speeds the adaptation process and maximizes protective benefit, since intermittent wear allows grinding to continue unprotected. Simple strategies such as wearing the guard for short periods while awake before full-time nightly use can help some patients acclimate more quickly. If adaptation problems persist, the clinician may modify the device or consider an alternative design.
Daily care is straightforward: rinse the night guard after removal, brush it gently with a soft toothbrush and nonabrasive toothpaste or mild soap, and allow it to air dry before placing it in a ventilated case. Avoid hot water, harsh chemicals, and household cleaners that can deform or degrade the material. For periodic deep cleaning, use a denture or oral appliance cleanser according to product instructions and your dentist’s guidance.
Always store the appliance in its protective, ventilated case to prevent distortion and contamination, and keep it away from pets, who are often attracted to the scent. Inspect the guard periodically for cracks, thinning, or other signs of wear, and bring it to dental appointments for professional review. Prompt replacement of a worn or damaged guard maintains effective protection and prevents unexpected dental problems.
A night guard can reduce excessive loading on the temporomandibular joint by limiting harmful clenching and redistributing occlusal forces, which may relieve muscular tension and decrease the frequency of painful spasms. Many patients experience fewer morning headaches and less jaw stiffness when a well-fitted appliance is part of their care plan. However, TMJ disorders are complex and can arise from joint pathology, muscle dysfunction, or systemic factors that require a broader treatment approach.
Management of TMJ pain often combines a night guard with other interventions such as physical therapy, targeted exercises, stress reduction, and, when appropriate, dental or medical referrals. Careful evaluation of the joint, muscles, and bite helps determine whether a guard alone is sufficient or if additional therapies are indicated. Ongoing follow-up ensures that the treatment plan is adjusted to the patient’s response and clinical findings.
A properly designed and adjusted custom night guard should not cause permanent tooth movement or undesirable bite changes because it is intended as a removable, protective overlay rather than a repositioning appliance. Ill-fitting over-the-counter devices, however, can produce uneven contacts or alter the way teeth meet, which in rare cases may contribute to bite changes or discomfort. Regular professional evaluation helps confirm that the appliance maintains even contact and does not negatively affect occlusion.
If a patient notices changes in bite, new tooth sensitivity, or persistent discomfort after beginning nightly use, they should contact their dentist promptly for assessment. Minor adjustments to the appliance often resolve fit-related issues quickly, while more significant concerns may require remaking the guard or exploring alternative management strategies. Ongoing monitoring preserves both comfort and dental health.
You should seek dental evaluation if you experience frequent morning jaw pain, unexplained headaches, increased tooth sensitivity, visible tooth wear, or if a sleep partner reports audible grinding. These signs suggest ongoing bruxism that may be causing progressive dental damage or stressing the temporomandibular joints. Early assessment enables timely intervention to protect tooth structure and dental restorations before more extensive treatment becomes necessary.
A comprehensive evaluation may include a clinical exam, bite analysis, radiographs, or digital scans, and it can identify whether a night guard, dental adjustments, or referral to a sleep specialist is indicated. Patients in Sandy Springs, Georgia can schedule an assessment with the team at Vernon Woods Dental & Implant Center to review symptoms and develop a personalized plan. Collaborative care that addresses both symptoms and underlying contributors yields the best long-term results.
