Many patients come to us wondering why their jaw feels sore in the morning or why teeth sometimes seem more sensitive than usual. Nighttime teeth grinding and jaw clenching—collectively known as bruxism—are common contributors to those symptoms. Left unaddressed, bruxism can place undue stress on teeth, gums, and the temporomandibular joints, and it can undermine sleep quality and daily comfort. At our Park Slope practice, we focus on clear explanations and practical solutions so patients can protect their smiles and restore restful sleep.
Bruxism is an involuntary habit in which the teeth are ground or the jaw is clenched. This behavior may occur during wakefulness or while sleeping; nighttime bruxism is particularly disruptive because it often goes unnoticed until symptoms appear. Common signs include morning jaw stiffness, tension headaches, tooth sensitivity, and the gradual wearing of enamel.
Triggers vary from person to person. Emotional stress and anxiety are frequently implicated, but bruxism can also stem from sleep disorders, an uneven bite, missing teeth, or dental misalignment. It’s helpful to think of bruxism as a symptom rather than a standalone condition—identifying contributing factors helps guide effective treatment.
Because symptoms can overlap with other oral or medical issues, a professional evaluation is important. During a consultation, your dental team will review your symptoms, examine tooth surfaces and jaw function, and consider whether additional testing or collaboration with a sleep specialist is warranted.
A night guard is a simple, noninvasive appliance worn over the teeth during sleep. Its primary role is to create a protective buffer between the upper and lower teeth, reducing the direct forces produced by grinding and clenching. By dispersing those forces, a night guard helps prevent chips, fractures, and excessive wear to enamel and restorations.
Beyond shielding tooth enamel, night guards reduce strain on the muscles of the jaw and can minimize pressure on the temporomandibular joints (TMJ). For many patients, this translates into fewer tension headaches, less jaw pain, and improved comfort on waking. In addition, wearing a properly fitted appliance can interrupt the habitual patterns that perpetuate bruxism.
It’s important to remember that a night guard manages the mechanical effects of bruxism—it does not “cure” all underlying causes. When paired with appropriate behavioral strategies, dental adjustments, or medical referrals as needed, a night guard becomes a key component of a comprehensive treatment plan.
Night guards come in different forms, and patients often ask whether an over-the-counter product is an acceptable short-term solution. Store-bought guards can offer a quick, temporary barrier, but they are made from generic materials that do not account for individual bite patterns. That can lead to poor fit, ongoing discomfort, or even altered jaw alignment over time.
A custom night guard made in a dental office begins with an accurate impression or digital scan of the teeth. That tailored fit ensures even contact across tooth surfaces and minimizes unnecessary movement of the jaw while sleeping. Clinically fabricated appliances also use materials chosen for durability, comfort, and the specific forces present in each patient’s bite.
For patients with significant wear, large existing restorations, or TMJ concerns, a custom appliance provides superior protection and predictable performance. Your dental team can explain the differences and recommend the most appropriate type of guard based on your oral health, habits, and long-term goals.
The path to a well-fitting night guard usually begins with a focused exam and discussion about your symptoms and daily habits. During the visit, the dentist will evaluate tooth wear, look for signs of current damage, and assess jaw motion. When a custom appliance is recommended, impressions or digital scans are taken to capture the precise contours of your bite.
Fabrication takes place in a dental laboratory or onsite from those impressions or scans. Once the night guard is ready, the patient returns for a fitting appointment. The dentist checks fit and comfort, makes any necessary adjustments, and provides guidance on how to insert and remove the appliance. Early follow-up helps ensure the appliance is working as intended and remains comfortable.
Adapting to a night guard typically takes a few nights to a couple of weeks. Some patients notice immediate relief in morning symptoms, while others experience gradual improvements as muscle tension decreases and tooth contact is reduced. Regular dental checkups allow the team to monitor the appliance and the ongoing condition of teeth and gums.
Proper care extends the life of a night guard and maintains oral hygiene. Rinse the appliance after use, clean it gently with a soft brush and mild soap or a dentist-recommended cleaner, and store it in a ventilated case away from heat. Avoid abrasive toothpaste or harsh chemicals that can degrade the material. Bring the guard to dental visits so the team can inspect it for wear and fit.
The useful lifespan of a night guard varies with material, the intensity of grinding, and how well it’s cared for. Over time, appliances can show signs of wear or may no longer fit exactly as they did initially. When that happens, an updated impression or scan and a replacement appliance will restore ideal protection.
If symptoms persist or worsen despite wearing a night guard, further evaluation is necessary. Ongoing pain, new noises in the jaw, or changes in bite may signal that additional treatments—such as occlusal adjustments, physical therapy, or a sleep study—should be considered. Working closely with your dental team ensures that any evolving issues are addressed promptly.
Night guards are a practical, evidence-based tool for protecting teeth, reducing jaw strain, and improving sleep comfort for many patients who grind or clench their teeth. With careful assessment, a custom fit, and routine maintenance, they play an important role in preserving oral health and preventing costly damage.

A night guard is a removable oral appliance worn during sleep to protect the teeth and reduce the effects of bruxism, the medical term for teeth grinding and jaw clenching. The guard creates a protective barrier between the upper and lower teeth to prevent direct tooth‑to‑tooth contact and to distribute biting forces more evenly. By separating the arches, it also reduces muscle strain and helps limit stress on the jaw joint, which can decrease morning pain and tooth damage.
Night guards do not change the position of the teeth but act as a mechanical buffer while you sleep, allowing tissues to recover and reducing the risk of chips, cracks, and excessive wear. They can also serve as a diagnostic tool to help your dentist evaluate the severity and pattern of grinding. For many patients, using a properly fitted guard is a conservative first step in managing the symptoms of bruxism.
Teeth grinding and jaw clenching have multiple causes, and more than one factor may be involved in a single person. Common contributors include stress and anxiety, sleep disruptions such as sleep apnea, an abnormal bite or misaligned teeth, and certain medications or habits like tobacco and excessive alcohol. Genetic predisposition and tooth loss or poorly fitting restorations can also change how the teeth come together and prompt grinding.
A thorough dental and medical history, along with a clinical exam, helps identify likely triggers and any associated conditions that need attention. Your dentist may ask about sleep quality, daytime jaw tension, and morning symptoms to determine whether a night guard or other therapies are appropriate. In some cases, collaboration with a physician or sleep specialist is recommended to address underlying sleep disorders.
Patients who show signs of tooth wear, cracked or chipped teeth, unexplained tooth sensitivity, persistent jaw soreness, or frequent morning headaches are often evaluated for a night guard. People diagnosed with bruxism through clinical signs or reports from a sleep partner may benefit from a protective appliance to prevent progressive dental damage. A night guard is also considered when temporomandibular joint (TMJ) symptoms or muscle pain appear to be aggravated by nocturnal clenching.
Children and adolescents may sometimes need an appliance, but treatment decisions are made carefully because their jaws and teeth are still developing. Your dentist will perform an exam and discuss lifestyle, sleep habits, and medical history to recommend the most appropriate solution, which could include a custom night guard, behavioral strategies, or a referral for further medical evaluation.
Night guards come in several types, including soft, hard acrylic, and dual laminate designs that combine a soft inner layer with a hard outer shell. Soft guards are generally more comfortable for light grinders but may wear faster, while hard acrylic guards are more durable and better suited for people who grind heavily. Dual laminate options aim to balance comfort with strength for moderate grinders and those who need additional shock absorption.
There are also over‑the‑counter boil‑and‑bite or stock appliances that offer temporary protection but often lack the precise fit and long‑term durability of a custom device. A custom night guard made from dental impressions or digital scans provides the best fit and is adjusted by the dentist to ensure proper jaw positioning and even contacts. Your dentist will recommend the material and design that best matches your symptoms and grinding intensity.
The process starts with a comprehensive dental exam to document wear patterns and check for signs of TMJ dysfunction or other oral health issues. Your dentist will take impressions or a digital scan of your teeth to capture an accurate model of your bite, which is used to fabricate a custom appliance in a dental laboratory. When the guard returns from the lab, the dentist will verify the fit, trim any areas of irritation, and make bite adjustments so the appliance sits comfortably and functions as intended.
Fitting appointments usually include instructions on how to insert, remove, and care for the guard along with a short period of adjustment while you adapt to wearing it at night. Follow‑up visits allow the dentist to refine the fit and assess clinical improvement in muscle soreness or tooth wear. For many patients the custom route offers superior comfort and protection compared with noncustom alternatives.
Daily cleaning helps prevent bacterial buildup and keeps the appliance fresh and functional. Rinse the guard under cool water after use, then gently brush it with a soft toothbrush and mild, nonabrasive soap or a cleanser recommended by your dentist; avoid hot water and harsh cleaning agents that can warp or damage the material. After cleaning, let the guard air dry completely before placing it in a ventilated storage case to reduce moisture and odor.
Regularly inspect the guard for signs of wear, cracks, or persistent odors and bring it to your dental visits so the dentist can check its condition. Replace the storage case when it becomes worn or difficult to clean, and keep the appliance away from pets, who are often attracted to the scent of dental plastics. Proper daily care extends the life of the device and supports oral health.
A night guard can reduce muscle overactivity and protect the joint from excessive forces, which may relieve jaw pain, muscle tenderness, and tension‑type headaches in many patients. By redistributing biting pressures and allowing the jaw muscles to relax during sleep, a properly fitted appliance often reduces the frequency and intensity of pain associated with bruxism. Results vary, and a night guard is typically one component of a multi‑modal approach to TMJ management.
For persistent or complex TMJ disorders, your dentist may recommend additional therapies such as physical therapy, jaw exercises, stress management techniques, or adjustments to dental work that interferes with your bite. If pain worsens after starting an appliance, contact your dentist promptly so the device can be rechecked and modified as needed. Long‑term relief often requires coordinated care and ongoing monitoring.
Over‑the‑counter stock guards and boil‑and‑bite appliances can provide short‑term protection for occasional or mild grinders, but they do not offer the precise fit and personalized adjustments of a custom device. A poor fit can lead to uneven contact, increased muscle activity, or changes in bite that create new symptoms over time. These products may be useful as a temporary measure but are not intended for long‑term management of chronic bruxism.
If you use an over‑the‑counter appliance and notice persistent soreness, worsening tooth sensitivity, or changing bite relationships, schedule a dental evaluation sooner rather than later. A custom night guard from a dental office is designed to match your bite, minimize adverse effects, and provide a durable solution tailored to your needs. Your dentist can help you weigh the pros and cons and decide which option is most appropriate.
The lifespan of a night guard varies with the material, the severity of grinding, and how well it is cared for, so replacement timelines differ from person to person. Some soft guards may show significant wear in less than a year for heavy grinders, while well‑made hard acrylic appliances can last several years with proper maintenance. Regular dental checkups are important because your dentist can detect early signs of wear or damage that indicate the need for repair or replacement.
Replace the guard if you see deep grooves, cracks, persistent odors, or if it no longer fits securely or causes new discomfort. Bring the appliance to your dental visits so the dentist can assess its condition and recommend the optimal replacement interval. Timely replacement helps preserve both your guard and the long‑term health of your teeth and supporting structures.
Coverage for night guards varies widely by plan and often depends on whether the appliance is considered medically necessary for a diagnosed condition such as bruxism or TMJ dysfunction. Some plans include benefits for occlusal appliances while others may have restrictions or require documentation from the dentist. Because policies differ, it is best to check directly with your insurer to understand specific coverage details and any required authorization.
The office of Zen Dentistry can assist by providing clinical documentation, submitting claims, and explaining the administrative steps involved in seeking coverage. If additional medical referrals or sleep studies are needed to support a claim, your dentist can coordinate care and offer guidance on the documentation typically requested by insurers. Verifying benefits before treatment helps you and your dental team plan the most appropriate course of care.
