What is Teeth Grinding?

Teeth grinding, also called bruxism, is when a person clenches or grinds their teeth without meaning to. It can happen during the day, but it is most common at night while sleeping. Many people do not realise they grind their teeth until a dentist spots signs of wear or a partner hears the noise.

Teeth grinding is a common condition in the UK. Studies suggest that around 8% to 10% of adults grind their teeth regularly, while up to 15% of children may experience it at some stage. In many cases, it is mild, but for some people it can cause pain and long-term damage.

What are the causes of teeth grinding?

There is no single cause of teeth grinding since it is usually linked to a mix of physical and emotional factors. Stress and anxiety are some of the most common triggers. People who feel under pressure at work or in daily life are more likely to grind their teeth, especially at night.

Sleep problems are another key cause. Conditions like poor sleep quality or disrupted sleep can increase the risk. Lifestyle habits such as smoking, alcohol, and high caffeine intake may also play a role.

In some cases, teeth grinding is linked to how the teeth fit together. If the bite is uneven, it can lead to clenching or grinding. Certain medications, especially some antidepressants, have also been linked to bruxism.

What is the best treatment for teeth grinding

There is no single cure, but there are several effective ways to manage and treat teeth grinding. The right option depends on the cause and severity.

• Wearing a custom-made mouth guard at night to protect the teeth

• Reducing stress through relaxation techniques such as mindfulness or exercise

• Improving sleep habits, including a regular bedtime routine

• Avoiding alcohol, smoking, and caffeine, especially in the evening

• Dental treatments to correct bite problems if needed

• In some cases, medical treatment or muscle relaxants may be recommended

Wearing a custom-made mouth guard at night - A custom mouth guard, provided by a dentist, is worn while sleeping to stop teeth from grinding against each other. It acts as a protective barrier, reducing damage to enamel and easing pressure on the jaw. It does not stop the grinding itself but prevents further harm.

Reducing stress - Stress is a major cause of teeth grinding, so managing it can make a big difference. Techniques like mindfulness, deep breathing, and regular exercise can help relax the body and reduce tension. This may lower the chances of clenching, especially at night.

Improving sleep habits - Good sleep habits can help reduce teeth grinding. Going to bed at the same time each night and creating a calm routine before sleep can improve sleep quality. Avoiding screens and relaxing before bed can also help the body settle.

Diet - Alcohol, nicotine, and caffeine can all increase the risk of teeth grinding. These substances can affect sleep patterns and make the jaw more active during the night. Cutting down, especially in the evening, can help reduce symptoms.

Dental treatment - If teeth grinding is caused by an uneven bite, a dentist may suggest treatment to correct it. This could include reshaping teeth (known as teeth contouring) or other dental work to improve alignment (such as Invisalign aligners). Fixing the bite can reduce strain on the jaw.

Medical treatment - For more severe cases, a doctor may recommend medication such as muscle relaxants to reduce jaw tension. These are usually used short-term and alongside other treatments. Medical advice is important to find the safest and most effective option.

What is the best prevention for teeth grinding?

Preventing teeth grinding often involves making simple lifestyle changes. Managing stress is one of the most important steps. Activities like walking, yoga, or breathing exercises can help relax the body and reduce tension.

Good sleep habits also make a difference. Going to bed at the same time each night and avoiding screens before sleep can improve sleep quality. Cutting down on caffeine and alcohol, especially later in the day, can also help reduce grinding at night.

Regular dental check-ups are important, as dentists can spot early signs and offer advice before the problem becomes worse. In some cases, using a mouth guard early can prevent damage.

Dentists may offer mouthguards to be worn overnight to help with the clenching of teeth

What are the risks of teeth grinding?

Teeth grinding can lead to a range of problems if it is not treated. One of the main risks is damage to the teeth. Grinding can wear down enamel, making teeth more sensitive and more likely to crack or break.

It can also cause jaw pain and stiffness. Some people develop headaches, earache, or facial pain as a result of constant clenching. Over time, it may lead to problems with the jaw joint, known as temporomandibular joint (TMJ) disorders.

In severe cases, teeth grinding can affect sleep quality and overall wellbeing. Around 70% of bruxism cases are linked to stress, which means it can also impact mental health if not managed properly.

Is teeth grinding connected to snoring?

Teeth grinding can be linked to snoring in some cases. Both conditions are connected to sleep and may happen at the same time. In particular, people with sleep disorders such as sleep apnoea are more likely to grind their teeth.

Sleep apnoea causes pauses in breathing during sleep, which can lead to snoring and disrupted rest. This can trigger the body to clench or grind the teeth as it reacts to airway blockage.

Not everyone who snores will grind their teeth, but if both symptoms are present, it is important to seek advice. Treating the underlying sleep issue can often reduce or stop the grinding.
