Teeth grinding, or bruxism, is more than just a bad habit. It is a sign that your jaw and muscles are under stress. Over time, this constant pressure can wear down enamel, cause fractures, and strain the joints that help you chew and speak comfortably.

What Is Bruxism?
Bruxism refers to the involuntary clenching or grinding of teeth, often during sleep or moments of stress. Over time, this constant pressure can lead to a wide range of dental problems that affect both comfort and appearance.
Common symptoms of bruxism include:
- Jaw pain or tightness: Often felt upon waking or after long periods of concentration.
- Headaches or ear pain: Caused by strain in facial muscles.
- Worn or chipped teeth: Grinding erodes the enamel, exposing sensitive layers.
- Tooth sensitivity: Thinner enamel allows hot or cold sensations to trigger pain.
- Cracked or fractured teeth: Severe cases can cause visible damage.
If you notice these signs, a professional evaluation is essential. Chronic grinding can contribute to TMJ disorders and even alter your bite alignment over time.
Why Teeth Grinding Happens
Bruxism does not have a single cause. It often develops from a combination of emotional, physical, and sleep-related factors. Stress and anxiety are leading triggers, particularly during sleep when you cannot consciously control jaw movement.
Other influences include:
- Sleep disorders such as snoring or sleep apnea
- Certain medications or stimulants like caffeine and antidepressants
- Lifestyle habits including alcohol use or smoking
- Abnormal jaw posture or muscle tension
- Genetic predisposition, as bruxism can run in families
Misaligned teeth do not typically cause grinding, but they can make its effects worse. When teeth do not meet evenly, the pressure from clenching or grinding tends to concentrate in specific areas, increasing wear and discomfort.
Why Bruxism Should Not Be Ignored
Even mild grinding can gradually wear down enamel, making teeth more sensitive and vulnerable to fractures. The repeated strain can also affect the jaw joints, leading to symptoms such as:
- Popping or clicking sounds when opening the mouth
- Facial pain or morning headaches
- Tension and stiffness around the jaw
- Broken fillings, crowns, or chipped enamel
Without treatment, bruxism can lead to long-term TMJ dysfunction and changes in bite alignment. Early intervention helps preserve the strength and comfort of your smile.
How Dentists Treat Bruxism
Treatment focuses on protecting the teeth, relieving muscle tension, and addressing contributing factors. Depending on your specific case, your dentist may recommend:
- Custom night guards: Worn during sleep to cushion the teeth and absorb the pressure from grinding.
- Correcting bite or alignment issues: Straightening or adjusting misaligned teeth with ClearCorrect aligners or braces can improve how your bite fits together, helping distribute pressure more evenly. While this is not a cure for bruxism, it can lessen strain and prevent uneven wear.
- Stress management strategies: Relaxation techniques, mindfulness, or behavioral therapy to reduce unconscious clenching.
- Physical therapy or jaw exercises: To stretch and relax overworked muscles.
- Sleep evaluation: For patients with symptoms of sleep apnea or disrupted sleep.
Your dentist will evaluate your teeth, jaw, and bite to design a plan that protects your oral health and restores comfort.

FAQs
Emotional stress and anxiety are major contributors to bruxism. Managing stress and maintaining proper dental alignment can help minimize its effects.
Because bruxism often has multiple causes, there is no single cure. The best approach is a combination of stress management, good sleep hygiene, and professional dental care. Your dentist may recommend a custom night guard, bite adjustment, or relaxation techniques to protect your teeth and relieve muscle tension.
It is common to notice temporary clenching or tension when you first start wearing aligners. Your jaw muscles are adjusting to subtle changes in tooth position and the feeling of the trays. This usually improves as your mouth adapts. If clenching continues or causes discomfort, your dentist can check your fit and make adjustments as needed.
