Identify Known Causes of Bruxism
Millions of people suffer each year from a condition known as Bruxism. Bruxism refers to the involuntary clenching or grinding of teeth, and it may not always announce itself with obvious symptoms. For many people, the first signs appear as worn-down teeth, an aching jaw, or a headache that just won’t go away. If you have bruxism and are looking for solutions, it helps to understand what’s behind the grinding in the first place. Bruxism doesn’t come from a single source and often has many different causes. It’s the result of a complex mix of physical, emotional, and even genetic factors. Read on to learn more.
Why Do People Clench and Grind Their Teeth?
Bruxism falls into two main types: awake bruxism and sleep bruxism. Although the behavior looks the same in both cases, what causes it can vary. Awake bruxism often shows up during times of stress. People clench their jaw without realizing it, sometimes in moments of frustration, concentration, or fatigue. It can become a habit that sticks around long after the original stressor is gone. Sleep bruxism, on the other hand, tends to be more subtle and harder to detect. People don’t usually know they’re grinding their teeth at night unless a partner hears it, they wake up in the morning with a sore jaw or teeth, or a dentist points it out. This form of bruxism is linked with disturbances in sleep and can occur in brief episodes during lighter sleep stages. Some research even connects it to micro-awakenings or changes in brain activity while asleep.
Risk Factors That May Contribute
There’s no single cause of bruxism, but certain patterns can increase the likelihood of developing it.
- Stress and Anxiety: Chronic stress and heightened emotions like anger or frustration are among the most well-known contributors to bruxism. For some people, clenching can become a physical response to mental pressure. Over time, it becomes more automatic.
- Age: Bruxism is common in children, especially when new teeth are coming in. Fortunately, many kids outgrow it. Adults can experience it too, but it often looks different and can be triggered by a wider range of issues.
- Personality Traits: People with high-energy or competitive personalities may be more prone to bruxism. If you tend to push hard, stay on high alert, or have trouble relaxing, your jaw muscles may reflect that tension.
- Lifestyle and Habits: Caffeine, alcohol, and nicotine can increase the frequency or severity of bruxism. So can chewing gum excessively or biting your lips and cheeks. These are small habits that keep your jaw active throughout the day.
- Medications and Health Conditions: Some medications, especially certain antidepressants or drugs used for ADHD and seizures, can list bruxism as a side effect. It’s not common, but it happens. Neurological conditions like Parkinson’s disease or sleep disorders such as sleep apnea may also play a role.
- Family History: Bruxism sometimes runs in families. If a parent or sibling has it, your chances may be higher. Genetics might not be the full explanation, but it could be one piece of the puzzle.
What’s the Bottom Line?
Bruxism can seem harmless at first, but the underlying causes are worth exploring because if left untreated, bruxism can cause more severe complications. If you suspect you might be grinding or clenching, talk with your dentist. They can help you identify the root of the issue. This is the first step toward protecting your smile and easing the tension that comes with it.
