Tooth grinding, also known as bruxism, is a common dental condition that involves clenching or grinding your teeth, often without realising it. While it can happen during the day, many people experience sleep bruxism, where grinding occurs unconsciously throughout the night.
Occasional teeth grinding may not cause significant problems, but persistent bruxism can place excessive pressure on your teeth and jaw. Over time, this can lead to worn enamel, cracked teeth, jaw discomfort and headaches.
Understanding what causes tooth grinding and recognising the early warning signs can help you protect your teeth and prevent further dental complications.
What Causes Tooth Grinding?
There isn’t always one single cause of bruxism. It can develop due to a combination of physical, psychological and lifestyle factors.
Some of the most common causes include:
1. Stress and Anxiety
Stress and anxiety are among the common factors associated with teeth grinding. When you’re feeling overwhelmed or tense, you may unconsciously clench your jaw or grind your teeth, particularly during sleep.
Emotional stress can also contribute to muscle tension around the jaw, making clenching more likely throughout the day.
2. Sleep Disorders
Sleep-related conditions, including obstructive sleep apnoea and other sleep disturbances, can be associated with sleep bruxism.
People who grind their teeth during sleep may experience disrupted sleep without necessarily being aware of the grinding itself. If you regularly wake up with jaw soreness, headaches or tooth sensitivity, it may be worth discussing your symptoms with your dentist.
3. Lifestyle Habits and Stimulants
Certain lifestyle habits can increase the likelihood of teeth grinding or make existing bruxism worse.
These include:
- Excessive caffeine consumption, particularly later in the day.
- Alcohol consumption, especially before bedtime.
- Smoking and nicotine use.
- Recreational drug use, including stimulants.
Reducing these triggers may help improve symptoms, particularly when combined with other preventative measures.
4. Certain Medications
Some medications, including certain antidepressants and stimulant medications, may contribute to bruxism.
If you notice that teeth grinding develops or becomes more frequent after starting a new medication, speak with your prescribing healthcare professional. They can assess whether your medication may be contributing and discuss appropriate alternatives if necessary.
5. Other Health and Neurological Factors
Bruxism can sometimes occur alongside certain neurological conditions and other medical conditions. It may also be associated with changes in sleep patterns and nervous system activity.
Because the causes can vary between individuals, a dental assessment can help identify potential contributing factors and determine the most appropriate treatment approach.
Signs and Symptoms of Teeth Grinding
Many people don’t realise they grind their teeth, particularly when it happens during sleep. However, there are several warning signs that may indicate bruxism.
Common symptoms include:
- Flattened, worn or chipped teeth.
- Increased tooth sensitivity.
- Jaw pain, tightness or soreness.
- Frequent headaches, particularly around the temples.
- Facial muscle discomfort.
- Earache-like pain without an underlying ear condition.
- Difficulty opening or closing your mouth comfortably.
- Disturbed sleep or waking up feeling tired.
Your dentist may also identify signs of excessive tooth wear or damage during a routine dental examination.
Recognising these symptoms early is important, as ongoing grinding can gradually damage your teeth and place additional strain on your jaw joints.
How Can Dentists Treat Tooth Grinding?
Treatment for bruxism depends on its underlying causes, severity and the extent of any existing dental damage. While there isn’t one universal solution, your dentist can recommend strategies to protect your teeth, relieve discomfort and manage contributing factors.
1. Custom-Made Night Guards
One of the most common dental treatments for sleep bruxism is a custom-made night guard or occlusal splint.
This removable appliance is worn over your teeth while sleeping. It creates a protective barrier between your upper and lower teeth, helping minimise direct tooth-to-tooth contact and reduce the risk of further wear, chipping or damage.
A custom-fitted night guard is designed to suit your bite and provides a more personalised fit than many over-the-counter alternatives.
It’s important to understand that night guards primarily protect your teeth rather than eliminate the underlying grinding behaviour.
2. Repairing Damaged Teeth
If bruxism has already caused noticeable tooth damage, restorative dental treatment may be necessary.
Depending on the extent of the damage, your dentist may recommend:
- Dental fillings to repair minor chips or areas of damage.
- Dental crowns to restore and protect weakened teeth.
- Other restorative treatments to rebuild damaged tooth structure.
Addressing existing damage helps restore the function and appearance of your teeth while reducing the risk of further complications.
3. Managing Stress and Anxiety
If stress is contributing to your teeth grinding, making changes to your daily routine may help reduce symptoms.
Some practical strategies include:
- Practising relaxation techniques, such as meditation or deep breathing.
- Maintaining a consistent sleep schedule.
- Incorporating regular physical activity.
- Reducing caffeine and alcohol consumption.
- Seeking professional support for ongoing stress or anxiety.
Developing healthier stress-management habits can complement dental treatment and help manage daytime clenching.
4. Addressing Underlying Sleep Issues
If your dentist suspects that sleep disturbances or sleep apnoea may be contributing to your bruxism, they may recommend further assessment by an appropriate healthcare professional.
Treating an underlying sleep condition may help improve sleep quality and address factors associated with nighttime grinding.
5. Monitoring Your Teeth and Jaw Health
Regular dental examinations are important for monitoring the effects of bruxism.
Your dentist can assess tooth wear, check for cracks or fractures, evaluate your bite and monitor any jaw discomfort. Early intervention can help prevent minor issues from developing into more extensive dental problems.
How to Prevent Teeth Grinding
Although not all cases of bruxism can be prevented, certain habits may help reduce its frequency and minimise its impact on your oral health.
Consider incorporating these habits into your daily routine:
- Be mindful of jaw tension: Keep your teeth slightly apart when resting, rather than clenching your jaw.
- Limit stimulants: Reduce your intake of caffeine, particularly in the afternoon and evening.
- Maintain good sleep habits: Aim for a consistent bedtime and a relaxing nighttime routine.
- Manage stress: Find practical ways to unwind and reduce tension throughout the day.
- Avoid chewing habits: Limit chewing on pens, fingernails or other hard objects that place additional strain on your jaw.
- Attend regular dental check-ups: Routine examinations allow your dentist to identify early signs of tooth grinding and recommend appropriate treatment.
If you suspect you’re grinding your teeth, don’t wait until you experience significant discomfort or visible damage. A dental assessment can help determine what’s happening and the best way to protect your smile.

Frequently Asked Questions
1. Can teeth grinding go away on its own?
In some cases, teeth grinding may improve when contributing factors such as stress, lifestyle habits or sleep disturbances are addressed. However, persistent bruxism may require ongoing management. Your dentist can assess the severity of your symptoms and recommend suitable treatment.
2. Does teeth grinding permanently damage your teeth?
Yes, prolonged and untreated bruxism can cause permanent tooth wear, enamel damage, cracks and fractures. Severe cases may also affect existing dental restorations. Early diagnosis and protective treatments, such as custom-made night guards, can help minimise further damage.
3. Should I see a dentist if I grind my teeth at night?
Yes. If you regularly grind your teeth during sleep, experience morning jaw pain or notice increased tooth sensitivity, it’s worth booking a dental examination. Your dentist can identify signs of bruxism, assess any existing damage and recommend appropriate treatment to protect your teeth.
