Bruxism can affect both adults and children. Although it’s more common for people to grind their teeth at night, it may also happen during the day. Sufferers usually aren’t aware they are doing it at all.<\/p>
Why do people grind their teeth? This condition can be caused by a range of things, but it is most often attributed to stress or anxiety. It can be hard to stop teeth grinding completely, but there are many ways to lessen its effects. Most people begin by using a mouth guard at night.<\/p>
In this article you can find out what causes bruxism, how to identify the symptoms, and what to do if you or someone you know is grinding their teeth.<\/p>
What is bruxism?<\/span><\/h2> This condition, also known as teeth grinding, involves excessive grinding or clenching of the teeth<\/strong> – usually without the person realising they are doing it. According to The Bruxism Association<\/a>, it affects around 8-10% of the population and is most common in people aged 25-44.<\/p> Although we all sometimes grind or clench our teeth to some extent, people suffering from bruxism do it to the point that it starts to damage their teeth or cause other medical problems.<\/p>
The condition can manifest itself in two ways:<\/p>
- Dynamic bruxism<\/strong> involves grinding jaw movements from side to side or from front to back, and usually occurs during sleep.<\/li>
- Static bruxism <\/strong>is a clenching of the jaw or teeth without making a sound, and more often happens during the day.<\/li> <\/ul>

Clenching teeth can be as problematic as grinding them<\/figcaption><\/figure><\/div> Nocturnal bruxism<\/strong>, the term for grinding your teeth in your sleep, represents 80% of cases<\/strong>. Also known as ‘sleep bruxism’, it involves adults or children grinding their teeth in their sleep in an involuntary and unconscious manner.<\/span><\/p> Sleep bruxism often occurs alongside other sleep disorders such as snoring and sleep apnoea. Patients commonly experience fatigue as their sleep is so badly disrupted. The same goes for anyone who may be sharing a room with them.<\/p>
Ask a dentist: Why do I have jaw pain when I wake up? <\/div> <\/p> If you wake up with an aching jaw and sore teeth, you are most likely grinding your teeth at night or sleeping with a clenched jaw. Another sign of nighttime jaw clenching can be waking up with a headache. All of these signs point to a problem with your jaw joints, known as your temporomandibular joints. This can be worse during seasons of life where you\u2019re stressed, or it can just be a chronic problem that needs to be treated with a custom-made bruxism guard.<\/p>

If you notice your partner grinding their teeth in their sleep, bring it to their attention. Encourage them to visit a dentist, who can check for signs of wear on teeth. Following diagnosis, there are various ways to reduce any oral damage and identify the underlying cause.<\/p>
In some cases it may be necessary to study a patient’s sleep patterns, which involves spending a night at a sleep laboratory in a hospital. The majority of cases don’t require this, but for particularly problematic cases it can be the most reliable diagnosis.<\/span><\/p> Clenching teeth while awake<\/h3>
Clenching your jaw or teeth during the day can also put excessive stress on your jaw muscles and cause damage to your teeth. If you catch yourself with gritted teeth or a tense jaw, it may well be because of stress. The bruxism exercises we feature later on can help you relax the muscles in question.<\/p>
Why do people grind their teeth?<\/span><\/h2> Bruxism treatment is complicated by the fact that there are so many possible causes for the condition. In fact in some cases, the teeth grinding cause may never be known.<\/span><\/p> However, current medical knowledge points towards the following factors:<\/p>
![\"teeth](\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2017\/01\/headache--300x300.jpg\")
Stress is often a bruxism cause<\/figcaption><\/figure><\/div> - Anxiety and stress – with teeth grinding or jaw clenching worsening as stress levels increase<\/span><\/span><\/li>
- Dental malocclusion<\/a> (misalignment of teeth) – although medical opinion is divided as to whether this is an outright cause, an aggravating factor, or a result of grinding<\/span><\/li>
- Psychosocial problems<\/span><\/li>
- Taking antidepressants<\/span><\/li>
- Taking drugs such as ecstasy<\/span><\/li>
- Smoking – smokers are five times more likely to experience problems<\/li>
- High alcohol or caffeine consumption<\/li>
- Sleep disorders<\/li>
- Tongue tie<\/a><\/li>
- Neurological conditions like Parkinson’s and Huntington’s disease<\/li> <\/ul>
Genetic causes cannot be ruled out. There appears to be a link, but it has not yet been clearly demonstrated.<\/span><\/p> Of all these bruxism causes, stress and anxiety are by far the most common<\/strong>. Almost 70% of diagnosed cases result from stress, for example at work or school. People who don’t handle stress well are more likely to grind their teeth.<\/p> Most people experience stress to varying degrees at different times of their lives. Often when stress levels subside, the tooth grinding symptoms disappear too.<\/p>
This BBC article<\/a> may be several years old but it gives more information about the links between stress and bruxism. The reader comments at the end may be reassuring to people who have just been diagnosed with the condition.<\/p> Bruxism symptoms<\/span><\/h2> Most people are unaware that they are grinding their teeth, especially at night. The most obvious symptom of bruxism is the sound of scraping and grinding. It is an unpleasant noise which those nearby are likely to notice.<\/p>
But you can’t count on other people to mention this to you, so you should look out for other teeth grinding symptoms<\/strong>. These include:<\/span><\/p> - Muscle pain and tension around the jaw and the temporomandibular joint. This leads to a sensation of stiffness and can limit capacity to open the mouth wide.<\/span><\/li>
- Earaches and tinnitus<\/li>
- Headaches<\/li>
- Pain around the neck, cheeks and shoulders<\/span><\/li>
- Disrupted sleep or waking up feeling tired despite thinking you have slept for long enough<\/span><\/li>
- Excessive wear on the surface of teeth (which can lead to tooth sensitivity<\/a>)<\/li>
- Broken fillings, crowns or other dental prostheses<\/li>
- Cracked or fractured teeth<\/li>
- Bleeding gums<\/a>, especially at night<\/li> <\/ul>
Your dentist will be able to check for signs that your teeth are being damaged by grinding. If you’re concerned, mention this at your next dental checkup.<\/p>
Effects of teeth grinding<\/span> and clenching<\/h2> Damage to teeth<\/span><\/h3> ![\"structure](\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2020\/12\/tooth-structure-diagram.svg\")
When enamel thins, yellow dentin shows through<\/figcaption><\/figure><\/div> When teeth are put under sustained pressure, the outer layer of enamel starts to wear or chip away. This exposes the next layer of the tooth – dentin. Increased sensitivity to hot and cold is one sign that your teeth have reached this stage. <\/span><\/p> Teeth may also become yellow or discoloured. This is because dentin is an orangey-yellow colour and it’s the outer enamel which gives teeth their whiter appearance. When enamel is worn down, the colour of the dentin shows through.<\/p>
When the protective layer of enamel erodes, teeth are at greater risk of decay and cavities<\/a>. Teeth will also be more susceptible to becoming loose<\/a> or fractures,<\/strong> especially in severe cases.<\/span><\/p> In addition, dental restorations and prostheses, including fillings, crowns, bridges and veneers, can easily become damaged from tooth clenching or grinding.<\/span><\/p> Damage to the jaw joint<\/span><\/h3> Increased clenching and grinding puts greater strain on muscles and the temporomandibular joint (jaw). <\/span><\/p> You may notice your jaw feels particularly stiff or painful in the mornings, when you wake up. You may also notice it becomes harder to open your mouth fully, or it hurts to yawn.<\/span><\/p> Another sign of jaw clenching problems is that the joint starts to make alarming cracking or popping noises during movement from talking or eating. In more serious cases, the jaw can become locked, caused by joint displacement or arthritis in the joint.<\/span><\/p> Each patient will experience these teeth grinding symptoms to different degrees, but they certainly don’t help with stress or anxiety levels. In fact, the manifestation of these effects can make anxiety worse, resulting in a vicious cycle. This is especially true for people who have never heard of these bruxism symptoms – or even the condition itself – so are unsure whether to seek medical help.<\/p>
Other consequences<\/span><\/h3> In the most serious cases, there may be destruction of the alveolar bone, aggravation of periodontal illnesses<\/a>, muscle pain in the head and mouth or even muscular hypertrophy (where the muscles grow to be abnormally large because of overuse).<\/span><\/p> Teeth grinding in children and babies<\/span><\/h2> Are you worried about your baby or toddler grinding their teeth<\/strong>? Figures for bruxism in children indicate that around 20% of children can be affected. However, real figures may be higher as the condition can often go unnoticed or unreported. <\/span><\/p> A child grinding their teeth at night is considered a sleep disorder, and it can often lead to behavioural problems due to poor sleep patterns. An episode lasts on average for 4 seconds and can happen up to 6 times an hour during the night, making for a tired and irritable child the next morning.<\/span><\/p> ![\"toddler](\"https:\/\/www.dentaly.org\/en\/wp-content\/uploads\/sites\/3\/2017\/01\/baby-teeth-1402483_1920-300x201.jpg\")
It’s distressing to hear children grinding teeth<\/figcaption><\/figure><\/div> Of course it is also distressing for a parent to hear their child or baby grinding their teeth. It most often happens after the baby teeth or adult teeth first appear. By the time adult teeth are fully formed, the grinding behaviour should have stopped.<\/p>
There appears to be a clear relationship between children grinding teeth and breathing irregularities such as breathing through the mouth<\/a> due to obstructed airways. Some surgeries can address problems related to sleep disordered breathing.<\/p> Anxiety and stress have also been linked, although they may be a result of interrupted sleep rather than the cause of grinding teeth. Your child might be stressed because of bullying at school<\/a> or some kind of disruption in their lives, so try talking to them to see if something is bothering them. In any case, calming activities before bedtime can reduce anxiety and hyperactivity.<\/p> Bruxism treatment<\/h2>

Teeth grinding mouth guard<\/span><\/h3> Most dentists will recommend patients try wearing a bruxism guard at night to protect their teeth.<\/p>

A custom mouth guard protects teeth from grinding at night<\/figcaption><\/figure><\/div> A mouth guard for teeth grinding<\/a> creates disocclusion between the upper and lower jaw; in other words, they can no longer touch and cause abrasion to teeth. The teeth grinding guard also absorbs some of the pressure from clenching and grinding.<\/span><\/p> An added benefit is a big reduction in the noise from tooth grinding at night – which can be a huge relief for the patient’s partner!<\/p>
The teeth are completely covered by the mouth guard so there is no contact between any upper and lower teeth.<\/span><\/p> Let’s be clear that a bruxism mouth guard is not a cure<\/strong> for this condition, no matter what the causes. It simply allows the jaw and muscles to relax and rest, thanks to the diminished pressure.<\/span><\/p> A mouth guard is not usually recommended for very young children whose facial and dental structure are still growing as it may interfere with normal dental development.<\/span><\/p> Bruxism mouth guard costs<\/span> in the UK<\/h3> Over-the-counter dental guards are available for around \u00a315 – \u00a340. Although affordable, these guards don’t offer a perfect fit and may not be as durable as custom-made varieties.<\/p>
A better option is to ask your dentist about getting a custom mouth guard<\/a> or splint. These are created from a dental impression and made in a laboratory to fit your teeth perfectly. The result is a more comfortable and longer-lasting product.<\/p> You may be able to get a bruxism mouth guard on the NHS, costing the band 3 treatment charge, which is \u00a3282.80 for 2020\/21. Alternatively, a private dentist can provide one costing anywhere between \u00a3100 and \u00a3500.<\/p>
Can you buy a mouth guard for teeth grinding online?<\/h3>
Yes, but be wary of the ‘one size fits all’ type. Some people have great success with these, whereas others find that only a custom-made mouth guard from a dentist helps with their bruxism pain. If you want to try a DIY version, these ones from Time2Sleep<\/a> are a good option. <\/p> To make them fit, you must immerse the guards in boiling water and then mould them to the shape of your teeth. Some people find this process difficult, and it doesn’t guarantee a perfect fit. You might find that your teeth hurt after wearing a night guard<\/a> if it doesn’t fit properly or if it’s to<\/a>o hard<\/a>. <\/p> You can also order bruxism guards online with a professional UK dental service. You’ll be sent an impression kit to take your own teeth impressions at home, then a dental lab will make your teeth grinding guard and post it to you. This service costs less than half what you’d pay at an NHS dentist, without the inconvenience of trying to get an appointment.<\/p>
