Bruxism is the medical term for regular teeth grinding and jaw clenching, and it often happens without the sleeper’s awareness. While some people experience occasional daytime clenching, many patients grind most noticeably during sleep. This unconscious activity can interrupt restorative sleep cycles, increase morning fatigue, and contribute to tension headaches or a feeling of tightness in the face and neck.
The forces involved in grinding are far greater than normal chewing pressures, so repetitive contact between upper and lower teeth can cause gradual wear, fractures, and sensitivity. Beyond tooth damage, sustained clenching can strain the muscles around the jaw and place continuous pressure on the temporomandibular joint (TMJ), which may lead to pain, limited movement, or clicking and popping sensations.
Because bruxism often has multiple contributors — including stress, sleep-disordered breathing, missing or misaligned teeth, and certain medications — diagnosing the underlying pattern is important. A careful history, examination, and discussion of symptoms allow a dental professional to determine whether a night guard is an appropriate first-line device to protect oral tissues and improve comfort.
A night guard is a custom-made oral appliance that fits over the teeth to provide a physical barrier and redistribute biting forces. Unlike over-the-counter “boil-and-bite” options, a professionally fabricated guard is made from impressions of the patient’s mouth and adjusted for precise fit, which improves comfort and reduces the risk of unwanted tooth movement or poor fit-related soreness.
By creating a cushioned layer between upper and lower teeth, the appliance prevents direct enamel-on-enamel contact that causes chipping and accelerated wear. It also holds the jaw in a slightly altered position that reduces muscle hyperactivity and decreases the strain placed on the TMJ during episodes of clenching and grinding. For many patients, using a night guard results in fewer headaches and less jaw stiffness upon waking.
Importantly, a well-designed night guard also protects dental restorations such as crowns and veneers from repetitive force. For patients who already have restorative work or are at risk for future damage, this preventive measure can preserve the longevity of dental care and reduce the likelihood of more invasive treatment later on.
Getting a custom night guard typically begins with a focused consultation that reviews symptoms and medical or dental history. The dentist will examine the teeth, assess bite relationships, and look for signs of wear, muscle tenderness, or TMJ dysfunction. If a night guard is recommended, the next step involves taking precise impressions or digital scans to capture the shape of the dental arches.
Laboratory fabrication usually follows, using materials selected for comfort and durability. At the insertion appointment, the clinician checks fit, makes any necessary adjustments, and provides instructions on how to insert and remove the device properly. Patients are encouraged to give feedback during this visit so small refinements can be made to eliminate pressure points or improve retention.
There is a brief adaptation period while the mouth becomes accustomed to sleeping with an appliance. Most patients report that any initial awareness diminishes within a few nights. Follow-up visits allow the dental team to monitor how the guard is performing and to make further adjustments if the bite changes or if the wearer notices persistent discomfort.
Proper care extends the life of a night guard and keeps it hygienic. Rinse the appliance after each use and clean it with a soft brush using non-abrasive toothpaste or mild soap; avoid hot water, which can distort the material. Store the guard in a ventilated case when not in use to prevent bacterial buildup while protecting it from damage.
Regularly inspect the night guard for signs of wear, holes, or thinning, and bring it to your dental appointments for evaluation. Even durable materials will eventually show wear if bruxism is severe, and a damaged guard can become less effective or uncomfortable. Your dentist can advise whether repair, reline, or replacement is needed based on the appliance’s condition and your ongoing symptoms.
Because night guards interact directly with oral tissues, maintaining a schedule of routine dental visits helps ensure both the appliance and your teeth stay healthy. These checkups also provide an opportunity to reassess underlying causes of grinding and to coordinate care with other healthcare providers when sleep disorders or systemic issues are suspected.
If symptoms persist despite using a night guard — for example, ongoing jaw pain, increased headaches, or new tooth sensitivity — additional evaluation may be necessary. The practice may recommend further diagnostic steps such as imaging, referral for a sleep study, or collaboration with a physician when medical conditions like obstructive sleep apnea are suspected contributors to nocturnal grinding.
For some patients, a night guard alone is sufficient to manage bruxism and protect dental health. Others may benefit from a multi-faceted approach that includes stress management techniques, physical therapy for the jaw muscles, or adjustments to dental restorations to improve bite alignment. Your dental team will help tailor a plan that reflects the specific findings from your exam and your individual health needs.
At Sunset Dental, we focus on listening to patients, explaining options clearly, and recommending solutions that prioritize long-term oral health and comfort. If you have questions about bruxism or whether a night guard could help you, our team will guide you through the evaluation and fitting process with attention to fit, function, and patient comfort.
In summary, night guards are an effective, conservative tool for protecting teeth, reducing jaw strain, and improving sleep-related symptoms linked to bruxism. If you’re experiencing morning jaw pain, headaches, or notice signs of tooth wear, contact us for more information and to discuss whether a custom night guard is right for you.
Bruxism is the medical term for chronic jaw clenching and grinding of the teeth that often happens during sleep and can lead to jaw pain, headaches, and sore or loosened teeth.
A night guard is a removable oral appliance that fits over the teeth and keeps the upper and lower jaws slightly apart to prevent the teeth from contacting each other directly and to reduce muscle strain.
Common signs that may indicate the need for a night guard include waking with jaw soreness or headaches, noticing worn or chipped enamel, increased tooth sensitivity, or hearing a grinding sound while you sleep.
Your dentist will evaluate your symptoms during an exam, check for wear patterns on your teeth, assess your bite and jaw function, and may recommend further evaluation for sleep disorders if indicated.
Night guards come in several materials and designs, including soft thermoplastic splints for mild grinding, hard acrylic guards for heavy grinders or those who clench forcefully, and dual-laminate appliances that combine a soft inner layer with a hard outer shell for both comfort and durability.
The best choice depends on the intensity and pattern of your bruxism, your bite, and any other oral health concerns, so a dentist should recommend the most appropriate type after an examination.
Making a custom night guard typically begins with a clinical evaluation and either a traditional impression or a digital intraoral scan to capture the exact shape of your teeth and bite relationship.
That model is used to fabricate a snug-fitting appliance in a dental laboratory, and the device is then tried in and adjusted chairside for comfort and proper fit by our team at Sunset Dental.
Rinse your night guard with cool or lukewarm water after each use and gently brush it with a soft toothbrush using mild, nonabrasive soap or a toothpaste recommended by your dentist to remove debris and bacteria.
Always allow the appliance to dry completely before storing it in its ventilated case, avoid exposure to high heat which can warp the material, and inspect it regularly for cracks or excessive wear.
The lifespan of a night guard varies based on the material used and how aggressively a patient grinds, with some appliances lasting many months and others remaining functional for several years.
You should replace your night guard when you notice visible wear, cracks, persistent odor, or a change in fit, and bring it to your dental appointments so the dentist can assess whether a replacement or adjustment is needed.
By preventing excessive tooth contact and reducing muscle overactivity, a night guard can help lower the strain on the temporomandibular joint and associated muscles, which often leads to fewer headaches and less jaw discomfort.
While a night guard can be an effective component of a treatment plan for TMJ-related symptoms, comprehensive management may include jaw exercises, physical therapy, sleep hygiene measures, or referrals to specialists if an underlying disorder is present.
When a night guard is custom-made and properly adjusted by a dentist, it should not permanently change your bite, and it is intended to protect teeth and joint structures rather than alter occlusion.
If you experience persistent discomfort, difficulty closing, or a noticeable change in how your teeth meet, contact your dentist promptly so the appliance can be evaluated and modified as necessary.
Most patients notice mild awareness of the appliance for the first few nights and may experience slight jaw or tooth soreness as muscles adapt, but this typically improves within a few days to a few weeks.
If adjustment is unusually slow or if the device causes significant discomfort, your dentist can make small changes to the fit or thickness to improve comfort and encourage consistent use.
A typical process at the Corvallis office begins with an evaluation of your symptoms and bite, followed by impressions or a digital scan, fabrication of a custom appliance, and an in-office try-in with adjustments to ensure comfort and effectiveness.
After delivery, patients are advised to bring the night guard to routine visits so the dentist can monitor fit and wear, make any necessary adjustments, and review care instructions to help maintain long-term oral health.
