Do I Need a Night Guard? Signs You're Grinding Your Teeth in Your Sleep

Many people grind or clench their teeth at night without realizing it. The first signs may include morning headaches, jaw soreness, increased tooth sensitivity, or unexplained wear on the teeth.

Nighttime teeth grinding, also known as sleep bruxism, may gradually wear down the teeth, place additional strain on the jaw muscles, and contribute to TMJ-related symptoms over time.

A custom night guard can help protect the teeth from grinding-related damage, but not every patient who grinds their teeth requires the same treatment approach. Keep reading to learn about common warning signs and when it may be appropriate to visit your dentist for a professional evaluation.

What Is a Night Guard?

A night guard is an oral appliance worn during sleep that fits between the upper and lower teeth. It helps create a protective barrier between the teeth and may reduce excessive forces caused by grinding or clenching.

A custom-fitted night guard is designed according to your individual bite and may provide a more precise and comfortable fit than over-the-counter alternatives.

Common Signs You’re Grinding Your Teeth at Night

Many people are unaware that they grind their teeth because it happens during sleep. Recognizing potential warning signs early may help reduce the risk of more extensive dental wear or jaw discomfort.

Morning Jaw Pain

If your jaw feels sore, stiff, or tired when you wake up, nighttime clenching or grinding may be contributing to the discomfort.

Morning jaw soreness can be a common sign that the jaw muscles have been under additional strain during sleep.

Frequent Headaches

Regular morning headaches, particularly around the temples, may sometimes be associated with muscle tension caused by nighttime clenching or grinding.

If headaches occur frequently along with jaw soreness or other dental symptoms, a professional evaluation may help determine whether bruxism is contributing to the problem.

Worn or Chipped Teeth

Repeated grinding can gradually wear down tooth enamel, flatten biting surfaces, chip the edges of teeth, and potentially contribute to cracked or fractured teeth.

Because these changes may develop gradually, patients may not recognize the damage until it becomes more noticeable or is identified during a dental examination.

Tooth Sensitivity

As enamel becomes worn, the underlying tooth structure may become more exposed.

This can contribute to increased sensitivity when consuming hot, cold, or sweet foods and beverages.

Clicking or Sore Jaw

Repeated grinding and clenching can place additional stress on the jaw joints and surrounding muscles.

Over time, this may contribute to clicking, popping, stiffness, soreness, or general TMJ discomfort.

Your Partner Hears Grinding

In some cases, a partner or family member may notice nighttime grinding sounds before the person experiencing bruxism becomes aware of the habit.

If someone regularly hears you grinding your teeth while you sleep, consider discussing it with your dentist.

Who Is Most Likely to Need a Night Guard?

Certain individuals may be more likely to experience sleep bruxism because of stress, lifestyle factors, or existing dental concerns.

You may benefit from a professional evaluation if you:

• Frequently clench your jaw
• Grind your teeth during sleep
• Experience chronic jaw pain
• Wake up with headaches
• Have visible tooth wear
• Experience TMJ-related symptoms
• Have increased tooth sensitivity
• Have a history of stress-related clenching

A dentist can evaluate your teeth, jaw, bite, and symptoms to determine whether a night guard may be appropriate.

Benefits of a Custom Night Guard

A custom night guard can help protect the teeth from excessive grinding and clenching forces while supporting overall oral comfort.

Potential benefits include:

• Helps protect tooth enamel
• May reduce the risk of cracks or fractures
• Helps reduce jaw muscle strain
• May minimize TMJ-related discomfort
• May improve comfort during sleep
• May reduce the risk of restorative treatment related to grinding damage
• Helps protect the natural bite and tooth structure

When Should You Visit Your Dentist?

If jaw pain, recurring headaches, tooth sensitivity, visible tooth wear, or nighttime grinding symptoms persist, consider scheduling a dental evaluation.

Your dentist can assess whether your symptoms may be related to bruxism, TMJ dysfunction, bite concerns, or another dental condition and recommend an appropriate treatment plan before more extensive damage develops.
