Waking up with a headache, sore jaw muscles, or achy teeth may be more than just a minor annoyance — it could be a sign of bruxism, the medical term for teeth grinding or jaw clenching. This common condition can cause lasting damage to your teeth and lead to a range of other issues if left untreated. Fortunately, experts offer a variety of strategies to manage bruxism and protect your oral health.
According to dental professionals, your teeth should only make contact while you’re eating or speaking. If you’re grinding or clenching, you’re subjecting your teeth to excessive wear, which can lead to tooth damage, headaches, jaw pain, and more. Dr. Leila Jahangiri, chair of prosthodontics at NYU College of Dentistry, explains that preventing unnecessary stress on the teeth can pay long-term health dividends.
Some individuals may not notice any symptoms of bruxism. Dr. Elizabeth Rae Hatfield, a clinical assistant professor at the University of Michigan School of Dentistry, notes that in some cases, bruxism is benign and goes unnoticed. However, for others, the signs are more apparent.
Common indicators of bruxism include:
Excessive wear on teeth: While all teeth naturally wear over time, bruxism accelerates this process, leaving teeth visibly worn down.
Sensitive teeth: If you experience sensitivity to hot or cold, especially in a generalized, non-specific way, it could be linked to grinding.
Sore jaw muscles: Aches or tightness in the jaw, especially upon waking, are telltale signs of clenching.
Headaches: Morning headaches, particularly around the temples, are common among those who grind their teeth at night.
Scalloped tongue: Indentations along the side of your tongue, caused by pressure from teeth, can occur during grinding episodes.
White lines on the cheeks: The formation of a white line (known as linea alba) along the inside of the cheek indicates frequent clenching.
Cracked or broken teeth: Repeated grinding can cause tooth fractures or damage to fillings.
The causes of bruxism remain somewhat elusive, as many factors contribute to the condition. According to Dr. Mark Messina, a dentist specializing in orofacial pain, bruxism is a collection of symptoms tied to multiple causes. Interestingly, daytime clenching and nighttime grinding may have different triggers, though they can overlap.
Stress and Anxiety: Stress is commonly associated with daytime bruxism, as the body attempts to release excess energy through clenching or grinding.
Sleep Disorders: Nighttime bruxism is often linked to sleep-related issues, such as obstructive sleep apnea (OSA) or gastroesophageal reflux disease (GERD).
Alcohol Use: Studies suggest a connection between alcohol consumption and increased teeth grinding.
Physical Activity: Some individuals report clenching while exercising or during stressful activities like driving, indicating a nervous response to tension.
The onset of bruxism has been notably heightened during times of increased stress, such as during the COVID-19 pandemic, which saw a rise in jaw pain, chipped teeth, and grinding behaviors, Messina adds.
The first step to managing bruxism is to recognize its symptoms. Once you become aware of the patterns, it’s important to consult with your dentist. A dental professional can help determine the underlying causes — whether stress, sleep apnea, or dental misalignment — and tailor a treatment plan accordingly.
Here are some common approaches to manage bruxism:
Mouthguards or Night Guards: A custom-made mouthguard can protect your teeth from damage caused by nighttime grinding. These devices don’t stop the grinding but help minimize the wear on your teeth and alleviate jaw strain. If daytime grinding is an issue, wearing the guard during the day might also be beneficial.
Botox Injections: For those who suffer from severe clenching, Botulinum toxin (Botox) injections are becoming a popular treatment. These injections can relax the muscles responsible for excessive clenching but may have side effects. A professional diagnosis is crucial to determine if Botox is right for you.
Stress Management Techniques: If anxiety or stress is a contributing factor, relaxation exercises such as deep breathing, meditation, or mindfulness can help alleviate bruxism. This is particularly effective for those experiencing daytime clenching or grinding.
Sleep Studies and Specialist Referrals: For patients whose bruxism is linked to sleep disorders or temporomandibular joint (TMJ) dysfunction, dentists may recommend a sleep study or a referral to an orofacial pain specialist for further evaluation.
Behavioral Biofeedback: If you catch yourself clenching during the day, Dr. Messina recommends a simple biofeedback technique. Try breathing deeply, holding your breath for a count of four, and then slowly exhaling while gently massaging your face and neck. This helps release jaw tension and break the cycle of clenching.
Bruxism is a common but often overlooked condition that can lead to serious dental and health issues if left untreated. Recognizing the symptoms early and seeking professional advice can prevent long-term damage. Whether through a customized night guard, stress management, or advanced treatments like Botox, there are multiple ways to manage teeth grinding and jaw clenching effectively. If you’re experiencing symptoms, don’t hesitate to consult your dentist — addressing the issue now can protect your smile for years to come.
