Bruxism — the habitual clenching or grinding of the teeth — often acts like a quiet thief, gradually wearing down enamel and stressing the muscles and joints that support your bite. While some people clench during the day when stressed or focused, many experience the most destructive episodes during sleep, when conscious control is absent. Nighttime grinding can be brief and infrequent, or it can be intense and repetitive, leaving a trail of symptoms that reveal its presence.
Common signs include morning jaw stiffness, dull headaches near the temples, and dental sensitivity that seems to come out of nowhere. Over time, untreated bruxism can contribute to cracked or flattened teeth, worn dental restorations, and increased pressure on the temporomandibular joint (TMJ). Because the behavior often happens during sleep, it’s not unusual for patients to be surprised when a dental exam points to grinding as the underlying problem.
Multiple factors can trigger or worsen bruxism. Emotional stress and anxiety are frequent contributors, but medical conditions like sleep disordered breathing, certain medications, an uneven bite, or missing teeth can also play a role. Identifying the combination of causes for each person helps the dental team recommend solutions that go beyond a one-size-fits-all approach.
A night guard is a simple mechanical solution with a powerful protective effect: it provides a resilient barrier between the upper and lower teeth while guiding the jaw into a safer resting position. By preventing direct tooth-to-tooth contact, the appliance dissipates grinding forces and reduces the risk of chipping, fracture, and accelerated wear. For many patients, that single change can significantly slow or stop the dental damage associated with nightly bruxism.
Beyond protecting hard tissues, night guards also reduce the load placed on the muscles and joints around the jaw. When the jaw is allowed to clench repeatedly, the surrounding musculature becomes fatigued and inflamed, which contributes to pain and stiffness. A properly fitted guard helps relax these muscles overnight, which frequently translates into fewer headaches and a more comfortable morning.
It’s important to understand that a night guard is a management tool, not a cure. While it prevents physical damage and eases symptoms, addressing the root causes — such as stress, bite alignment, or sleep issues — may require coordinated treatment with your dentist or other healthcare providers. Still, for immediate protection and symptom relief, a night guard is one of the most effective noninvasive options available.
Over-the-counter mouthguards offer a low-cost, temporary answer, but they can fall short in comfort, fit, and long-term effectiveness. Custom night guards are made from impressions or digital scans taken at the dental office and are crafted to match the precise contours of your teeth and bite. This tailored fit improves comfort, encourages consistent use, and provides more reliable protection against grinding forces.
Materials and thickness are also selected to suit individual needs. Some patients benefit from a firmer acrylic device that shields teeth from severe grinding, while others do better with a slightly softer material that cushions sensitive surfaces. Your dentist evaluates the pattern of wear, muscle activity, and any existing restorative work to recommend the most appropriate design.
Because they’re custom-made, these appliances are also easier to adjust if your bite changes or if you experience new symptoms. Periodic checkups allow the dental team to confirm that the guard continues to fit properly and to make refinements that maintain both comfort and protective function.
Night guards are commonly recommended for people who show clear signs of bruxism on examination or who report symptoms such as jaw pain, chronic headaches, or unexplained tooth sensitivity. Patients with dental restorations — crowns, veneers, or large fillings — often receive a night guard as a preventive measure to shield those costly restorations from excessive forces. Similarly, anyone with visible wear facets on their teeth or a history of chipped enamel may be a candidate.
In addition to those classic indicators, night guards can help patients who experience TMJ discomfort or who have been diagnosed with certain sleep-related issues that increase nocturnal muscle activity. The decision to prescribe an appliance is individualized: your dental team will weigh the pattern and severity of grinding, your overall oral health, and lifestyle factors to determine whether a night guard is the right step.
For some people, night guards are a temporary intervention while other treatments are explored — for example, stress management, physical therapy for the jaw, or orthodontic correction. For others, especially those with chronic or severe bruxism, the guard becomes a long-term protective strategy that preserves oral health and reduces pain.
Caring for a night guard is straightforward and helps the device function well for as long as possible. Rinse the guard after each use, brush it gently with a soft toothbrush and nonabrasive soap, and store it in its ventilated case away from heat. Avoid harsh chemicals, hot water, or boiling, as those can warp the material and compromise the fit.
Even with diligent care, night guards are subject to wear and may need replacement or adjustment over time. Regular dental visits provide an opportunity for your provider to inspect both the appliance and your teeth for signs of ongoing grinding or changes in the bite. If you notice increased discomfort, a looser fit, or new symptoms such as worsening headaches, you should schedule an evaluation sooner rather than later.
Routine follow-up is also a chance to reassess whether the guard remains the best treatment option. As factors like stress levels, dental restorations, and sleep patterns evolve, your dental team will recommend modifications — from trimming or hardening the device to considering additional therapies — that align with current needs.
At the office of Silk Dental Delray Beach (formerly Marc Bilodeau DMD), our approach is to combine practical protection with thoughtful long-term care. A well-made night guard can stop destructive forces in their tracks and provide measurable relief, while coordinated follow-up care addresses the underlying contributors to bruxism. If you’re noticing signs of nighttime grinding or waking with jaw pain, contact us for more information about whether a custom night guard is right for you.
