Many people grind or clench their teeth without even realizing it. While occasional teeth grinding, also known as bruxism, may not cause lasting problems, chronic grinding can gradually wear down your teeth, strain your jaw muscles, and even contribute to headaches and facial pain.
Because teeth grinding often happens during sleep, many patients don’t know they have the condition until a partner hears the grinding or their dentist notices signs of damage during a routine examination. Left untreated, bruxism can affect not only your teeth but also your bite, jaw joints, and overall oral health.
At Wren Street Dental in Mission, BC, we help patients identify the causes of teeth grinding and develop personalized treatment plans to protect their smiles. If you’ve been waking up with jaw soreness, headaches, or sensitive teeth, call (604) 820-8702 to schedule an evaluation.
What Is Teeth Grinding?
Teeth grinding, or bruxism, is the involuntary clenching, grinding, or gnashing of your teeth. It can happen while you’re awake or asleep, though sleep bruxism is often more difficult to recognize because it occurs unconsciously.
Some people clench their teeth without making any grinding noise, while others grind with enough force to wear away tooth enamel over time.
The pressure created during sleep can actually exceed the force used while eating, making untreated bruxism surprisingly damaging over the long term.
What Causes Teeth Grinding?
Bruxism doesn’t usually have a single cause. Instead, it’s often the result of several contributing factors working together.
Common causes include:
- Stress and anxiety
- Poor sleep quality
- Obstructive sleep apnea
- Bite imbalances
- Missing teeth
- Certain medications
- Caffeine or alcohol before bedtime
- Smoking
- Neurological conditions
Because every patient is different, identifying the underlying cause is an important part of successful treatment.
Signs You May Be Grinding Your Teeth
Many symptoms of bruxism develop slowly, making them easy to overlook.
Common warning signs include:
- Morning headaches
- Jaw pain or stiffness
- Facial muscle soreness
- Worn or flattened teeth
- Chipped or cracked teeth
- Tooth sensitivity
- Earaches without an ear infection
- Neck pain
- Clicking or popping in the jaw
- Difficulty opening your mouth comfortably
Your dentist may notice these signs during a routine examination long before they become severe enough for you to recognize on your own.
How Teeth Grinding Affects Your Teeth
One of the first areas affected by chronic bruxism is the enamel—the hard outer layer of your teeth.
Over time, constant grinding can:
- Wear down chewing surfaces
- Create tiny cracks in teeth
- Increase tooth sensitivity
- Damage fillings and crowns
- Chip porcelain restorations
- Shorten teeth
- Change your bite
As enamel becomes thinner, the softer dentin beneath is exposed, often making teeth more sensitive to hot, cold, or sweet foods.
In severe cases, extensive restorative treatment may be needed to rebuild worn teeth.
The Connection Between Bruxism and TMJ Disorders
Your temporomandibular joints (TMJs) allow your jaw to move every time you speak, chew, yawn, or swallow.
Repeated clenching places significant stress on these joints and the surrounding muscles.
Over time, this may contribute to symptoms such as:
- Jaw clicking
- Jaw locking
- Pain while chewing
- Facial tenderness
- Reduced jaw movement
- Chronic headaches
Not everyone with bruxism develops TMJ disorder, but the two conditions are often related.
If you experience persistent jaw discomfort along with teeth grinding, your dentist may evaluate your jaw joints as part of your examination.
How Is Teeth Grinding Diagnosed?
Diagnosis usually begins with a comprehensive dental examination.
Your dentist may look for:
- Flattened tooth surfaces
- Chipped enamel
- Fractured fillings
- Muscle tenderness
- Changes in your bite
- Signs of gum recession
- Tooth mobility
- Jaw joint symptoms
You may also be asked questions about your sleep habits, stress levels, headaches, or whether anyone has heard you grinding your teeth at night.
Because sleep apnea and bruxism sometimes occur together, additional evaluation may be recommended in certain cases.
Treatment Depends on the Cause
There isn’t a one-size-fits-all solution for bruxism.
Instead, treatment focuses on protecting your teeth while addressing contributing factors whenever possible.
Depending on your needs, your dentist may recommend:
A Custom Night Guard
A professionally made night guard cushions your teeth and helps reduce the damaging effects of grinding while you sleep.
Unlike over-the-counter boil-and-bite guards, custom appliances are designed specifically for your bite, providing a more comfortable fit and better protection.
Managing Stress
If stress contributes to your grinding, relaxation techniques, regular exercise, improved sleep habits, or counseling may help reduce symptoms.
Bite Evaluation
Occasionally, bite irregularities contribute to excessive clenching or uneven pressure on certain teeth.
Your dentist will determine whether your bite is playing a role in your symptoms.
Restoring Damaged Teeth
If bruxism has already caused significant wear, restorative treatment may be recommended to rebuild damaged teeth and restore proper function.
Can Teeth Grinding Be Prevented?
Not every case of bruxism can be prevented, but several habits may reduce your risk.
Helpful strategies include:
- Limiting caffeine later in the day
- Avoiding alcohol before bedtime
- Practicing stress management
- Maintaining a consistent sleep schedule
- Wearing a custom night guard if recommended
- Scheduling regular dental examinations
Early diagnosis is often the key to preventing extensive damage.
Don’t Ignore the Signs of Bruxism
Because teeth grinding often develops gradually, it’s easy to dismiss occasional jaw soreness or morning headaches.
However, the longer bruxism continues untreated, the greater the risk of permanent damage to your teeth and jaw.
If you’ve noticed signs of grinding—or someone has told you they hear you grinding your teeth while you sleep—it’s worth discussing the issue with your dentist.
