Grinding your teeth in your sleep: Causes, symptoms and natural solutions

There’s nothing quite like waking up after what should have been a full night’s sleep, only to be greeted by a sore jaw or a nagging headache. If this sounds familiar, you could be experiencing grinding teeth in sleep, also known as bruxism.

The good news? You’re certainly not alone. Teeth grinding is surprisingly common and, while it isn’t always serious, it can affect your sleep quality, dental health and overall wellbeing if left unchecked. Understanding why it happens is the first step towards managing it.

In this guide, we’ll explore what causes grinding teeth while sleeping, the symptoms to watch out for, and practical ways to support a more restful night.

Bruxism is the medical term for repeatedly grinding, clenching or gnashing your teeth. It can happen while you're awake (awake bruxism) or during sleep (sleep bruxism).

Sleep bruxism happens unconsciously, so many people don't realise they're doing it until a partner mentions the noise or their dentist spots signs of wear on their teeth.

According to NHS guidance, around one in ten people experience sleep bruxism, making it a relatively common sleep-related condition.

There's rarely one single cause of sleep bruxism. Instead, several physical and lifestyle factors can contribute.

Stress is considered the most common trigger for teeth grinding. When we're feeling tense or anxious, that tension can carry over into our sleep, causing the jaw muscles to clench or grind without us realising.

People with certain sleep conditions, including snoring and obstructive sleep apnoea, appear to be more likely to grind their teeth during the night. Poor-quality sleep may also make episodes more frequent. 

While your mattress won't directly stop bruxism, creating a calm, comfortable bedroom can support deeper, better-quality sleep and reduce stress—both of which may help minimise triggers associated with teeth grinding.

Some everyday habits may increase the likelihood of bruxism, including:

• Drinking too much caffeine

• Smoking

• Drinking excessive alcohol

• Certain antidepressant or sleep medications

These factors don't necessarily cause bruxism on their own but may make it worse. 

Although it's less common than previously thought, some people may grind their teeth because of problems affecting the jaw or bite. Your dentist can advise if this is contributing in your case.

Because bruxism can happen while you're asleep, the symptoms are often easier to notice than the grinding itself.

Common bruxism symptoms include:

• Jaw pain or stiffness when you wake up

• Morning headaches

• Earache (without an ear infection)

• Worn, chipped or cracked teeth

• Sensitive teeth

• Facial pain

• Poor-quality or disturbed sleep

• A partner hearing grinding noises overnight

Your dentist may also notice flattened tooth surfaces or damage during a routine check-up.

It's not unusual for a child grinding teeth in sleep to concern parents. Many children grind their teeth occasionally, particularly while their teeth are developing, and often grow out of the habit.

However, if your child regularly complains of jaw pain, headaches or damaged teeth, it's worth discussing it with your dentist or GP. The NHS recommends seeking advice if you're worried about your child's teeth grinding.

Occasional teeth grinding usually isn't a cause for concern. However, frequent or severe bruxism can lead to problems over time.

Possible complications include:

• Cracked or broken teeth

• Worn enamel

• Tooth sensitivity

• Damage to fillings or crowns

• Jaw pain and temporomandibular disorders (TMD)

• Ongoing headaches

• Poor sleep quality

The sooner the underlying cause is identified, the easier it is to prevent further damage. 

Not necessarily.

Some children naturally stop grinding as they grow older, while adults may experience periods where symptoms improve or worsen depending on stress levels, sleep quality and overall health. It's not considered an inevitable part of ageing. 

If your teeth grinding is causing pain or damaging your teeth, there are several bruxism treatment options available.

Your dentist may recommend:

• A custom-made night guard or mouth splint to protect your teeth

• Monitoring tooth wear

• Treating damaged teeth if necessary

If stress or anxiety appears to be contributing, your GP may suggest support such as stress management techniques or talking therapies. If medication could be playing a role, they can also review your prescription. 

If you're wondering how to stop grinding teeth in sleep naturally, lifestyle changes can often make a real difference.

Since stress is such a common trigger, try winding down before bed with:

• Gentle stretching

• Deep breathing exercises

• Meditation

• Reading

• A warm bath

Even 15-20 minutes of relaxation before bed can help signal to your body that it's time to rest.

Good sleep hygiene can support deeper, more restorative sleep.

Aim to:

• Go to bed at the same time each night

• Limit screens before bed

• Keep your bedroom cool, quiet and dark

• Reduce caffeine later in the day

• Avoid excessive alcohol in the evening

These are all recommendations supported by the NHS for improving sleep and helping reduce teeth grinding.

You may also find it helpful to:

• Avoid chewing gum if your jaw feels sore

• Stay active to help manage stress

• Eat a balanced diet

• Keep up with regular dental check-ups

It's a good idea to speak to your dentist or GP if:

• Your jaw is painful or stiff most mornings

• You have cracked, chipped or worn teeth

• Your headaches are becoming frequent

• Your sleep is regularly disrupted

• Your partner hears you grinding your teeth every night

• You're worried about your child grinding their teeth

Early advice can help prevent long-term dental damage and identify any underlying causes.
