What Causes Grinding of the Teeth?

Teeth grinding, also known as bruxism, is something that can happen to just about anyone. While it’s more common at night when you’re asleep, some people also grind their teeth when they’re awake, especially if they’re feeling stressed or anxious. If you leave teeth grinding untreated, it can lead to a whole range of dental issues, including worn-down teeth, jaw pain, and headaches. So, what exactly causes it? Let’s have a look at the different reasons people grind their teeth.

10 Things That Cause Grinding of the Teeth

1. Stress and Anxiety

Stress is one of the biggest culprits behind teeth grinding. When we’re stressed or anxious, our bodies react in different ways – and grinding your teeth is often one of them. It’s something most people do without realising, especially when they’re asleep and not consciously aware of it. If you’ve got a lot going on at work or home, or you’re feeling anxious about something, chances are you might find yourself grinding your teeth more often.

2. Sleep Disorders

Sleep disorders like sleep apnea or snoring can contribute to teeth grinding too. Sleep apnea happens when your airways are partially or fully blocked while you sleep, causing your breathing to stop and start. The body responds by tightening the jaw, which can lead to bruxism. People who snore (a common sign of sleep apnea) are often more likely to grind their teeth. If you have a sleep disorder, it’s worth speaking to a health professional about treatment options to reduce teeth grinding.

3. Misaligned Teeth or Bite Issues

If your teeth aren’t properly aligned or your bite isn’t quite right, it can cause bruxism. An incorrect bite places pressure on the teeth, which might lead to grinding, particularly when you’re asleep. Things like overbites, underbites, or crooked teeth can stop your mouth from closing naturally, causing you to grind your teeth to “correct” the discomfort. Braces or dental treatments to fix bite issues can sometimes help prevent this.

4. Caffeine and Alcohol

Too much caffeine or alcohol can also make teeth grinding worse. Caffeine is a stimulant, and it can interfere with your sleep, increase anxiety, and make you more likely to grind your teeth while you’re sleeping. Alcohol, too, can disrupt your sleep and relax your jaw muscles, increasing the chances of grinding. Cutting back on caffeine and alcohol can be a simple but effective way to reduce teeth grinding.

5. Medications and Drug Use

Certain medications may contribute to bruxism as a side effect. Some types of antidepressants and antipsychotic medications have been linked to teeth grinding. Similarly, recreational drugs like ecstasy and methamphetamines can also trigger it. If you’re on medication and suspect it’s contributing to your teeth grinding, it’s worth talking to your doctor to explore alternatives or adjustments.

6. Health Conditions

A few health conditions can also cause teeth grinding. These include:

Neurological disorders: 

Conditions like Parkinson’s disease and Huntington’s disease can sometimes lead to bruxism.

Mental health disorders: 

If you have OCD (obsessive-compulsive disorder) or ADHD (attention-deficit/hyperactivity disorder), you might be more likely to grind your teeth.

TMJ Disorders: 

Issues with the temporomandibular joint (TMJ), which connects your jaw to your skull, can cause pain and discomfort, leading to teeth grinding.

7. Genetics

Sometimes, bruxism runs in families. If your parents or siblings grind their teeth, you might be more likely to do the same. While environmental factors like stress play a role, genetics can make you more prone to grinding your teeth. If you know bruxism runs in your family, keeping an eye on your own habits can help you catch it early.

8. Nutritional Deficiencies

If you’re not getting enough of certain nutrients, it might contribute to teeth grinding. For example, a lack of magnesium has been linked to muscle cramps and spasms, including in the jaw muscles. A balanced diet rich in vitamins and minerals can help reduce the likelihood of grinding your teeth. If you’re concerned you’re not getting enough nutrients, consider seeing a dietitian or your GP for advice.

9. Age

Bruxism can also affect kids, especially during the growth phase when their teeth are developing. Some children grind their teeth because of the eruption of new teeth or misalignment of baby teeth. The good news is that most kids outgrow bruxism, but if it’s persistent or causing issues, it’s worth getting checked out by a dentist. Adults can experience bruxism, too, especially if it’s linked to stress or other factors.

10. Psychological Factors

Psychological factors, such as anger, frustration, or even excitement, can also lead to teeth grinding. If you tend to react strongly to emotions, you might find yourself grinding your teeth as a subconscious response to those feelings. People who struggle with stress management or have unresolved emotional issues might grind their teeth more often.

How to Manage Teeth Grinding

If you think you might be grinding your teeth, it’s important to address the root cause of the issue. Here are a few things that might help:

Stress Relief: 

Try stress-reducing activities like yoga, meditation, or deep breathing exercises to help calm your mind and reduce anxiety.

Mouthguards: 

A custom-fitted mouthguard can protect your teeth from the damage caused by grinding. You can get one from your dentist.

Dental Treatment: 

If your teeth aren’t aligned properly, getting orthodontic treatment like braces could help prevent bruxism caused by bite problems.

Better Sleep: 

Improving your sleep hygiene can help reduce the likelihood of grinding your teeth at night. If you have a sleep disorder, getting it treated can make a big difference.

Medication Changes: 

If your medications are causing the grinding, talk to your doctor about alternative treatments.
