Yes, teeth grinding (bruxism) can cause serious dental damage over time, including worn enamel, cracked teeth, jaw pain, and tooth sensitivity. Early diagnosis and treatment, such as a custom nightguard and stress management, can prevent long-term harm and protect your oral health.
You wake up with a sore jaw, a dull headache, or teeth that feel oddly sensitive. Sound familiar? These are classic signs of bruxism, the clinical term for teeth grinding or clenching. Many people don’t even realize they’re doing it, especially when it happens during sleep.
Bruxism is more common than most people expect. According to the American Academy of Sleep Medicine, sleep bruxism affects approximately 8-10% of adults and up to 15-40% of children. And while grinding your teeth occasionally may seem harmless, chronic bruxism is a different story. Left untreated, it can wear down your enamel, fracture your teeth, and lead to a cascade of dental and jaw problems.
The good news? Teeth grinding is manageable. With the right care from a trusted dental clinic, you can protect your smile and stop the damage before it progresses. This guide covers everything you need to know, what causes bruxism, how it damages your teeth, and what your dentist can do to help.
What Is Teeth Grinding (Bruxism)?
Bruxism refers to the involuntary grinding, gnashing, or clenching of teeth. It falls into two main categories:
- Sleep bruxism: Occurs during sleep and is classified as a sleep-related movement disorder. Because it happens unconsciously, many people aren’t aware of it until a partner mentions the sound, or a dentist spots the signs.
- Awake bruxism: Happens during waking hours, often in response to stress, concentration, or anxiety. People with awake bruxism may clench their jaw or press their teeth together without realizing it.
Both types can cause real damage, but sleep bruxism tends to be more severe because people apply grinding forces without the awareness to stop themselves.
What Causes Teeth Grinding?
Bruxism doesn’t have a single cause. Several factors can contribute to or worsen the habit:
- Stress and anxiety: Psychological stress is one of the most well-documented triggers for both sleep and awake bruxism.
- Sleep disorders: People with obstructive sleep apnea are at higher risk of sleep bruxism.
- Certain medications: Some antidepressants, particularly SSRIs, have been linked to bruxism as a side effect.
- Caffeine and alcohol: High consumption of either can intensify grinding, especially before bed.
- Bite misalignment: An uneven bite or crooked teeth can create unequal pressure across the jaw, contributing to clenching habits.
- Genetics: Bruxism tends to run in families, suggesting a hereditary component.
Understanding the root cause matters, because effective treatment often depends on addressing what’s driving the grinding in the first place.
How Does Teeth Grinding Damage Your Teeth?
Does chronic bruxism wear down tooth enamel?
Yes, and this is often the most significant consequence. Enamel is the hardest substance in the human body, but it has its limits. Repetitive grinding creates friction that gradually wears away the enamel surface, the protective outer layer of each tooth.
Once enamel is gone, it doesn’t grow back. The underlying dentin becomes exposed, making teeth more vulnerable to decay, sensitivity, and further damage. Over time, worn enamel can actually change the shape and height of teeth, altering your bite and facial structure.
Can teeth grinding cause cracked or chipped teeth?
Absolutely. The pressure exerted during grinding can be extreme, far beyond normal chewing forces. This can lead to micro-fractures in teeth that are invisible to the naked eye at first, but eventually become full cracks or chips. Fractured teeth may require crowns, bonding, or in severe cases, extraction.
Dental restorations like fillings, crowns, and even dental implants can also sustain damage from chronic grinding. If you’ve already invested in restorative or cosmetic dentistry, whether that’s teeth whitening, dental implants, or crowns, protecting that investment with bruxism treatment becomes even more important.
What other dental problems can bruxism cause?
Teeth grinding doesn’t just affect the teeth themselves. A broader range of issues can develop, including:
- Tooth sensitivity: As enamel wears down, you may notice sharp pain when eating hot, cold, or sweet foods.
- Gum recession: Repeated clenching can put stress on the gum tissue and bone supporting the teeth, contributing to gum recession over time. This is particularly relevant for patients already managing gum disease.
- Loose teeth: In severe cases, grinding can loosen teeth by affecting the supporting bone and ligaments.
- Jaw joint problems (TMJ disorders): The temporomandibular joint, the hinge connecting your jaw to your skull, takes a significant hit from bruxism. TMJ disorders can cause jaw pain, clicking or popping sounds, difficulty opening your mouth fully, and chronic headaches.
- Facial muscle pain: The muscles used during grinding become overworked and sore, leading to facial pain, ear pain, and tension headaches.
How Do Dentists Diagnose Teeth Grinding?
Because sleep bruxism happens unconsciously, many people discover they grind their teeth during a routine dental exam and cleaning. During a checkup, a dentist looks for telltale signs:
- Flattened, chipped, or worn tooth surfaces
- Increased tooth sensitivity reported by the patient
- Damage to existing dental restorations
- Indentations on the tongue or cheek tissue from clenching
- Jaw muscle tenderness
This is one of many reasons why regular dental exams matter so much. Bruxism caught early is far easier, and less costly, to manage than bruxism that’s been quietly causing damage for years.
At Clinique Dentaire Pointe-Claire, our team provides thorough dental exams designed to catch early warning signs like these. Serving patients across Pointe-Claire and the West Island of Montreal, our clinic offers complete dental care for adults, seniors, and families.
What Are the Treatment Options for Teeth Grinding?
Custom nightguards: the first line of defense
A custom-fitted nightguard (also called an occlusal splint) is typically the most recommended solution for sleep bruxism. Worn over the upper or lower teeth during sleep, a nightguard creates a physical barrier between your teeth, absorbing grinding forces and protecting enamel.
Over-the-counter mouthguards are available at pharmacies, but they don’t compare to custom appliances made from impressions of your teeth. A custom nightguard fits precisely, is more comfortable to wear, and provides far better protection.
Stress management and behavioral strategies
Since stress is a major driver of bruxism, addressing it can significantly reduce grinding. Techniques like cognitive behavioral therapy (CBT), mindfulness, regular exercise, and improving sleep hygiene have all shown benefit. Your dentist may recommend working alongside a physician or therapist if stress or anxiety is a clear contributing factor.
Addressing bite alignment
If teeth grinding is linked to an uneven bite, orthodontic treatment may help by distributing bite pressure more evenly. At Clinique Dentaire Pointe-Claire, we offer orthodontic services for both adults and children, including options to improve bite, alignment, and function. Correcting the underlying bite issue can reduce the mechanical triggers for clenching.
Repairing the damage
If bruxism has already taken a toll on your teeth, restorative dental treatments can help rebuild what’s been lost. Depending on the extent of the damage, options may include:
- Dental bonding for minor chips or worn edges
- Dental crowns for more significant structural damage
- Veneers to restore the appearance of worn front teeth
- Dental implants if a tooth is beyond repair and needs replacement
Addressing the grinding itself is essential before investing in any restorative work, otherwise, the same forces that caused the original damage will wear down the new restorations too.
Can Children Grind Their Teeth?
Yes. Teeth grinding in children is relatively common, particularly in younger kids as they transition between baby and permanent teeth. In many cases, childhood bruxism resolves on its own. However, it’s worth mentioning to your child’s dentist, who can monitor for any signs of enamel wear or bite changes.
At Clinique Dentaire Pointe-Claire, our pediatric dentistry services are designed to make dental visits comfortable and stress-free for younger patients. Routine exams help catch bruxism and other concerns early, when they’re simplest to manage.
Protecting Your Smile Starts With a Dental Exam
Bruxism is one of those conditions that’s easy to ignore, until the damage becomes hard to miss. Worn teeth, cracked enamel, jaw pain, and persistent headaches don’t have to be your normal. With early diagnosis and the right treatment plan, teeth grinding is highly manageable.

Frequently Asked Questions About Teeth Grinding
How do I know if I grind my teeth at night?
Common signs include waking up with jaw soreness or headaches, noticing tooth sensitivity that wasn’t there before, and having a partner tell you they can hear grinding sounds while you sleep. A dentist can confirm bruxism by examining your teeth for signs of wear during a routine dental exam.
Is teeth grinding serious enough to see a dentist about?
Yes. While occasional teeth grinding may not cause lasting harm, chronic bruxism can permanently damage your enamel, crack teeth, and lead to jaw disorders. A dentist can assess the severity and recommend an appropriate treatment plan before serious damage occurs.
What happens if teeth grinding is left untreated?
Untreated bruxism can lead to significant enamel loss, cracked or broken teeth, increased tooth sensitivity, gum recession, and temporomandibular joint (TMJ) disorders. Over time, the structural damage may require costly restorative treatments such as crowns or dental implants.
Can a nightguard completely stop teeth grinding?
A nightguard doesn’t stop the grinding reflex itself, it protects your teeth from the effects of grinding. To reduce or eliminate bruxism, most dentists recommend combining a nightguard with strategies to address the underlying cause, such as stress management or bite correction.
Does teeth grinding affect dental implants or other restorations?
Yes. The excessive force from grinding can damage dental implants, crowns, veneers, and fillings over time. If you have existing restorations or are planning restorative treatment, your dentist will likely recommend treating bruxism first to protect your investment.
Is teeth grinding in children something to worry about?
Mild bruxism is common in children and often resolves on its own. That said, a pediatric dental exam is recommended to monitor for enamel wear or bite issues. Your dentist will advise whether any intervention is needed based on the child’s specific situation.
How do I choose the right Pointe Claire dentist for my family?
Look for a Pointe Claire dentist who provides comprehensive dental care for children and adults, offers convenient appointments, uses modern technology, and takes time to explain treatment options. A family-friendly clinic can make regular dental care easier for everyone.
