Many people grind or clench their teeth without realizing it.
Because it often happens during sleep, the first signs may not be obvious. Instead, you might wake up with jaw discomfort, notice changes in your teeth, or hear from your partner that you’ve been grinding your teeth at night.
While not everyone with these symptoms needs a night guard, recognizing the warning signs can help you know when it’s time to talk to your dentist.
Here are some of the most common signs that may indicate you could benefit from a night guard.

1. You Wake Up with Jaw Pain or Stiffness
One of the most common signs of nighttime teeth grinding or clenching is soreness or stiffness in the jaw when you wake up.
This discomfort often improves as the day goes on, but if it happens regularly, it’s worth mentioning to your dentist.

2. Frequent Morning Headaches
Some people who grind or clench their teeth wake up with headaches, especially around the temples.
Morning headaches can have many different causes, but nighttime muscle tension associated with bruxism may be one possible reason.
—
3. Your Teeth Look Worn Down
Over time, repeated grinding can gradually wear away the chewing surfaces of your teeth.
You may notice:
– Flattened teeth
– Chipped edges
– Teeth that appear shorter than before
Because tooth wear usually develops slowly, many people don’t notice it until their dentist points it out.

4. Increased Tooth Sensitivity
If the protective enamel becomes worn, your teeth may become more sensitive to hot, cold, or sweet foods and drinks.
Tooth sensitivity has many possible causes, but tooth grinding is one factor that may contribute.

5. Your Partner Hears Grinding Sounds
Many people are completely unaware that they grind their teeth while sleeping.
In fact, a bed partner is often the first person to notice the sound.
If someone tells you that you grind your teeth at night, it’s worth discussing with your dentist—even if you don’t have any symptoms.

6. Cracked Teeth or Broken Dental Restorations
Excessive biting forces may contribute to cracked teeth or damage to fillings, crowns, or other dental restorations.
These problems can have several causes, so your dentist can help determine whether grinding or clenching may be involved.
—
7. Your Teeth Feel Sore When You Wake Up
Some people notice that their teeth feel tired, tender, or slightly sore in the morning.
This may occur because the teeth have been under pressure for several hours during sleep.
—
8. You Often Clench Your Teeth During the Day
Bruxism doesn’t only happen at night.
Some people unconsciously clench their teeth while working, driving, exercising, or concentrating.
If you notice that your teeth are frequently touching or tightly clenched during the day, it’s a good idea to mention it during your next dental visit.

Does Having One Sign Mean You Need a Night Guard?
Not necessarily.
Many of these symptoms can have causes unrelated to teeth grinding or clenching.
Only a dentist can determine whether a night guard is appropriate after evaluating your teeth, your bite, and your symptoms.

When Should You See a Dentist?
Consider scheduling a dental evaluation if you:
– Frequently wake up with jaw pain or headaches.
– Notice worn, chipped, or cracked teeth.
– Experience increasing tooth sensitivity.
– Have been told you grind your teeth while sleeping.
– Feel persistent discomfort in your jaw or teeth.
Early evaluation may help identify the cause of your symptoms before more significant tooth wear or damage develops.

Final Thoughts
Teeth grinding and clenching are common, and many people don’t realize they’re doing it.
Paying attention to early warning signs—such as jaw discomfort, worn teeth, tooth sensitivity, or morning headaches—can help you seek professional advice before more serious problems develop.
If you think you may be grinding or clenching your teeth, your dentist can evaluate your oral health and discuss whether a night guard or another treatment option may be appropriate for your individual needs.
