Waking up with a sore jaw or a dull headache that fades by lunchtime is easy to shrug off, especially when you cannot remember anything happening while you slept. But those small, recurring aches are often the clearest evidence of a habit you never see yourself doing: grinding or clenching your teeth at night.
At Sopris Smiles, we look for these signs during every comprehensive exam because nighttime grinding, known as bruxism, can quietly wear down a smile long before you notice a problem. Our comprehensive dental exams go beyond checking for cavities, evaluating your bite and jaw function so we can catch this kind of wear early and help you understand what your teeth are trying to tell you.
Bruxism happens when the jaw muscles contract and move the teeth against each other, usually without any conscious effort involved. According to the National Institute of Dental and Craniofacial Research, bruxism refers to habits like teeth grinding, clenching, and jaw thrusting that often occur without a person realizing it, whether they are asleep or awake.
Stress and anxiety are among the most common triggers, along with misaligned bites, certain medications, and lifestyle factors like caffeine or alcohol use close to bedtime. For some people, sleep disorders play a role as well, which is one reason we look at the whole picture during a new patient visit rather than just the teeth themselves.
One cause that often goes undiagnosed is airway compromise. When the airway is restricted during sleep — whether from enlarged tonsils, a narrow airway, mouth breathing, or conditions like sleep-disordered breathing — the body responds by moving the jaw forward in an attempt to open the airway. That jaw movement is often what drives grinding and clenching, making bruxism as much an airway issue as a stress issue in many patients. Acid reflux, which is also associated with airway problems, can compound the wear pattern on teeth as well.
Because grinding usually happens while you are asleep, most people find out through symptoms rather than catching themselves in the act. Recognizing the pattern early can help you avoid more involved treatment down the road.
If several of these sound familiar, it may be worth asking us about it at your next visit rather than waiting for discomfort to build.
Occasional grinding on its own may not cause lasting harm, but frequent or severe bruxism can gradually reshape your bite. Over time, the constant pressure can wear down enamel, loosen teeth, and even lead to fractures that require restorative work. It can also strain the temporomandibular joint, the hinge connecting your jaw to your skull, which is why some patients experience TMJ discomfort alongside their grinding symptoms.
Left unaddressed, this wear pattern tends to snowball. What starts as mild sensitivity can progress into cracked crowns or the need for restorative dentistry to repair damage that could have been managed earlier with a simple night guard.
During your visit, we look closely at your teeth for flattening, microfractures, and uneven wear patterns — but we don’t stop there. Wear on teeth can be a sign of something deeper, including airway issues that are disrupting sleep without you ever knowing it.
At Sopris Smiles, we use CBCT 3D imaging to evaluate airway size and volume, alongside a clinical airway exam where we assess tonsil size, tongue posture, nasal versus mouth breathing patterns, and signs of acid reflux. Understanding the full picture is essential before recommending any treatment.
This is also why we don’t simply hand every patient with wear a night guard. Dr. Golnaz follows Kois protocols for occlusal evaluation — a systematic approach to deprogramming the jaw muscles and establishing where your bite truly wants to sit, before building any treatment plan around it. A night guard given without that foundation can actually lock in a problematic bite position rather than protect against it. Our goal is a stable, well-supported occlusion — whether that means an occlusal appliance, a deprogrammer splint, orthodontic treatment through our BeSmyle collaboration with Dr. Matt Stout, or a combination of approaches tailored to what your jaw actually needs.
Nighttime teeth grinding is common, but that does not mean it should be ignored. Catching the signs early, whether it is jaw soreness, headaches, or a partner’s observation, gives us the chance to protect your smile before wear turns into something more involved. Dr. Golnaz Samimifar and our team take a whole-health approach to every exam, looking beyond cavities to understand what your bite and jaw are telling us about your overall well-being.
Whether you need a custom night guard, a bite evaluation, or simply want a professional opinion on what you are experiencing, our team is ready to help you find real relief. With advanced digital scanning technology and a genuinely welcoming, family-friendly approach to care, we make it easy to get answers about symptoms you have been noticing.
