Bruxism, or teeth grinding, often happens during sleep, which means many people don’t realize they’re doing it until damage shows up. Common warning signs include waking up with jaw soreness, morning headaches, worn or chipped teeth, and a partner who notices grinding sounds at night. A custom-fitted night guard is the most reliable way to protect your teeth from further wear while the underlying cause, often stress or a misaligned bite, is addressed.
What Is Bruxism (Teeth Grinding)?
Bruxism is the medical term for clenching or grinding your teeth, and it can happen while you’re awake or, more commonly, while you’re asleep. Sleep bruxism is considered a sleep-related movement disorder, and because it occurs unconsciously, many people go months or years without realizing they’re doing it — often finding out only after a dentist spots the telltale wear pattern during a routine exam.
7 Warning Signs You’re Grinding Your Teeth at Night
- Morning jaw soreness or tightness that improves as the day goes on
- Frequent headaches, especially at the temples, right after waking up
- Worn, flattened, or chipped teeth that a dentist notices during a checkup
- Increased tooth sensitivity to hot, cold, or sweet foods
- A partner or family member who has heard grinding sounds while you sleep
- Jaw clicking or popping, particularly when opening wide or chewing
- Cheek or tongue indentations from clenching pressure during the day
If more than one or two of these sound familiar, it’s worth bringing up at your next dental visit, since early intervention is far easier than repairing extensive wear later on.
What Causes Teeth Grinding?
Stress and Anxiety
Stress is one of the most common triggers for bruxism, and grinding often increases during particularly demanding periods at work, school, or home. Many patients aren’t consciously aware of the connection until a dentist points out the physical evidence.
Sleep Disorders (the Sleep Apnea Link)
Bruxism is also closely associated with sleep disorders, particularly obstructive sleep apnea. In some cases, grinding is actually the body’s response to a partially blocked airway during sleep, which is why persistent grinding paired with loud snoring or daytime fatigue is worth mentioning to both a dentist and a physician.
Misaligned Bite
An uneven bite or missing teeth can cause the jaw to grind in an attempt to find a comfortable resting position, making orthodontic evaluation an important part of diagnosing chronic bruxism.
Night Guard vs. Mouthguard: What’s the Difference?
The terms are often used interchangeably, but they serve different purposes. A sports mouthguard is designed to absorb impact and protect teeth during athletic activity, and is typically worn during the day. A night guard is specifically designed to be worn while sleeping, cushioning teeth from the sustained pressure of grinding and clenching rather than a single impact. Over-the-counter versions of both exist, but a custom-fitted appliance from a dentist offers a far more precise, comfortable fit and holds up significantly longer than a one-size-fits-all option. Our custom mouthguards in Roanoke are molded from an impression of your own bite for exactly this reason.
How a Custom Night Guard Protects Your Teeth
A custom night guard creates a smooth, even surface between your upper and lower teeth, absorbing the pressure of grinding so your enamel doesn’t take the full impact. Because it’s molded to your exact bite, it stays in place comfortably through the night and can also help ease jaw tension by keeping your bite in a more relaxed position. Over time, a night guard can prevent the cracked teeth, worn enamel, and jaw pain that untreated grinding tends to cause.
When to See a Dentist About Teeth Grinding
If you notice any combination of jaw soreness, headaches, or visible tooth wear, it’s worth having a dentist take a look before the damage progresses. A dentist in Roanoke can examine your bite, check for early signs of enamel wear, and determine whether a custom night guard, a bite adjustment, or further evaluation for sleep-related causes is the right next step.
Getting Fitted for a Night Guard in Roanoke
Getting fitted for a custom night guard typically takes just one or two short appointments — an impression visit followed by a fitting once your guard is ready, with most patients back to normal daily routines the same day. If you’re noticing signs of grinding or waking up with jaw soreness, don’t wait for it to get worse: schedule a consultation at our Roanoke office and we’ll help you find the right solution to protect your smile.
Frequently Asked Questions
Can teeth grinding damage your teeth permanently?
Yes. Untreated grinding can wear down enamel, crack teeth, and stress the jaw joint over time, which is why a custom night guard is usually recommended once symptoms appear.
How do I know if I need a night guard?
Morning jaw soreness, headaches, flattened or chipped teeth, and a partner noticing grinding sounds are the clearest signs it’s time to see a dentist about a night guard.
Are custom night guards better than store-bought ones?
Custom night guards are molded to your bite for a precise, comfortable fit and hold up far longer than one-size-fits-all versions from a drugstore.
Does insurance cover night guards?
Many dental plans cover a portion of a custom night guard when it’s prescribed for diagnosed bruxism. Your dentist’s office can confirm your specific benefits.
