Grinding Your Teeth? Signs and Treatment for Bruxism

Many people grind or clench their teeth without ever realizing it. In fact, you may sleep through the entire episode and only notice the effects when you wake up with a sore jaw, a headache, or teeth that suddenly feel more sensitive. Because the habit often happens unconsciously, many people live with bruxism for months or even years before a dentist identifies the problem. The National Institute of Dental and Craniofacial Research notes that while many cases of bruxism are mild, more severe cases can lead to damaged teeth, jaw pain, headaches, and other oral health complications.

If you have noticed these symptoms, scheduling an evaluation with the best dentist in Mountain View can help determine whether nighttime teeth grinding is the cause. Here, we’ll explain the common signs of bruxism, why it happens, the risks of leaving it untreated, and the treatment options that can help protect your smile.

How Do I Know if I Grind My Teeth at Night?

Because bruxism happens while you're asleep, it rarely announces itself. Many patients first learn they grind their teeth after a spouse hears the noise at night or after a dentist notices unusual tooth wear during a routine exam.

Some of the most common signs of bruxism include:

• Waking up with jaw soreness or tightness
• Frequent morning headaches
• Tooth sensitivity without an obvious cause
• Flattened, chipped, or cracked teeth
• Clicking, popping, or discomfort in the jaw
• Pain while chewing or opening your mouth

These symptoms do not always point to bruxism, but they deserve attention. Teeth naturally experience wear over time, yet excessive grinding creates a very different pattern. A dental examination can reveal subtle signs of damage long before they become painful or require more extensive treatment.

What Causes Bruxism?

One of the most common questions patients ask is, "Why do I grind my teeth?" The answer rarely comes down to a single cause. Instead, several factors often work together.

Common causes of bruxism include: 

• Stress and Anxiety: Stress and anxiety remain two of the biggest contributors. Many people unconsciously clench their jaw during the day, and that tension can continue while they sleep. Busy schedules, major life changes, and emotional stress can all make nighttime grinding more likely.
• Sleep Disorders: Research has found a connection between sleep bruxism and conditions such as obstructive sleep apnea. When breathing becomes disrupted during sleep, grinding or clenching may occur more frequently.
• Other Causes: Other contributing factors can include changes in your bite, missing teeth, certain medications, and lifestyle habits such as frequent caffeine or alcohol consumption. 

What Happens if Bruxism Goes Untreated?

Grinding your teeth every now and then is fairly common. The problem starts when it happens night after night. Over time, that repeated pressure can wear away your teeth and put extra stress on your jaw.

Untreated bruxism can lead to:

• Cracked, chipped, or severely worn teeth
• Broken fillings, crowns, or other dental restorations
• Increased tooth sensitivity as enamel wears away
• Chronic jaw pain and TMJ disorders
• Difficulty chewing comfortably or fully opening the mouth

Many patients assume they only need treatment if they experience pain. Unfortunately, damage often develops long before discomfort appears. A small crack today can eventually become a tooth that requires a crown or root canal if the grinding continues.

Early intervention allows your dentist to protect your teeth before significant damage occurs, which often saves both time and money in the long run.

How Do Dentists Treat Bruxism?

Bruxism treatment focuses on protecting your teeth while also addressing whatever contributes to the grinding. Every patient's treatment plan looks a little different because the causes vary from person to person. Treatment for teeth grinding includes: 

• Night Guard for Teeth Grinding: For many patients, a custom night guard provides the first line of defense. Unlike over-the-counter mouth guards, a custom mouth guard fits your teeth precisely and helps distribute biting forces more evenly while you sleep. Although a night guard will not stop the grinding itself, it can significantly reduce the damage it causes.
• Treatment of Underlying Factors: Your dentist may recommend treating underlying factors that contribute to bruxism. Depending on your situation, that could include stress management strategies, relaxation techniques, evaluating you for a sleep disorder, or coordinating care with another healthcare provider when appropriate.
• Restorative Treatments: If grinding has already damaged your teeth, you may require restorative treatment. Repairing worn or fractured teeth restores both function and comfort while preventing additional complications.

The sooner you address bruxism, the more options you typically have to preserve your natural teeth and avoid more complex treatment later.
