Teeth Grinding: What Helps Against Bruxism During Sleep?

Teeth grinding, medically known as bruxism, is something many of those affected do not notice themselves at first. Often it is the partner who hears the nightly grinding, or the dental practice that discovers worn teeth. Typical signs are a tense jaw in the morning, headaches in the temple area, sensitive teeth or a tired feeling in the cheeks. Usually an unconscious overactivity of the chewing muscles is behind it, frequently triggered by stress and inner tension. Grinding can rarely be switched off at the push of a button, but with relaxation, good sleep habits and dental protection you can effectively relieve the jaw and teeth. When an assessment makes sense and what role individual nutrients play, you can read here.

What lies behind teeth grinding?

In bruxism, the jaws unconsciously press and rub against each other, predominantly during sleep, more rarely also during the day. Considerable forces arise in the process that can be well above the normal chewing pressure. The body evidently processes tension in this way, since stress, emotional strain and unprocessed stimuli are considered important contributing triggers. Sleep quality also plays a role, as grinding episodes frequently coincide with brief waking reactions.

Further factors can be an unfavourable bite situation, certain stimulants and pick-me-ups such as a lot of caffeine, alcohol or nicotine, as well as individual medications. Often several causes act together. Important to know: teeth grinding is common and, in a mild form, not automatically in need of treatment. It becomes problematic when teeth are visibly damaged or complaints arise in the jaw and head.

A rough distinction is made between sleep bruxism, which takes place unconsciously at night, and awake bruxism, in which people press their teeth together during the day in phases of concentration or stress. Both forms can occur individually or together. Night-time bruxism is often only noticed through its consequences, such as worn tooth surfaces, imprints of the teeth on the edge of the tongue or tense cheek muscles in the morning. Awake bruxism, on the other hand, is easier to observe yourself and to counteract specifically in everyday life by consciously noticing the pressing and repeatedly relaxing the jaw.

When you should have it assessed

Dental or medical advice makes sense if you regularly wake up in the morning with a tense jaw or headaches, if your teeth become sensitive, are visibly worn or wobble, if the jaw hurts, clicks or locks, or if those around you point out loud nightly grinding. Persistent ear or facial pain should also be assessed. The dental practice can recognise damage and offer protective measures. With persistent or unusual complaints, professional advice is always the right decision, since early protection prevents lasting tooth damage.

What helps in everyday life

Since stress is a central trigger, relaxation is at the centre. Fixed rituals for winding down in the evening, conscious breathing exercises, movement during the day and a counterbalance to strain can lower inner tension. During the day, take care not to press your teeth together; the rows of teeth normally only touch when chewing and swallowing. A brief inner check throughout the day helps to notice the pressing and let go.

Warmth on the cheeks is felt by many to be beneficial because it stimulates blood flow and loosens the chewing muscles. In the evening, reduce caffeine, alcohol and heavy meals, as they can disturb sleep. Ensure a quiet, dark bedroom and regular sleep times. In cases of proven grinding, an individually fitted bite splint from the dental practice is often the most important protection for the teeth.

Even during the day, a conscious approach to strain is worthwhile. Anyone who notices that they automatically clench their jaws in demanding situations can build in short breaks, loosen the shoulders and rest the tongue gently against the palate while the rows of teeth part slightly. Some people additionally benefit from guided relaxation techniques such as progressive muscle relaxation or mindfulness exercises, which help to lower the general level of tension. Sufficient movement in the fresh air and a regular daily rhythm additionally support the body in coming to rest better in the evening.

Sleep and night-time rest

Because the grinding happens predominantly at night, it is closely linked to sleep quality. Restful, quiet sleep supports the general regeneration of muscles and the nervous system. Helpful are a fixed sleep rhythm, a screen-free phase before going to bed and a cool, quiet environment. Anyone who finds it hard to come to rest in the evening often benefits from a fixed evening routine that signals to the body that the day is ending. It makes sense to consciously arrange the evening more calmly, to limit the consumption of exciting content and bright screen light and instead to plan relaxing activities such as reading or quiet music. A notebook by the bed can also help to get rid of circling thoughts before falling asleep, so that the mind does not keep working into sleep.

Nutrients and plants in focus

Around muscles, nerves and sleep, individual nutrients are mentioned. For some there are clearly regulated EU claims. Thus the following applies: Magnesium contributes to normal muscle function and contributes to the normal function of the nervous system. Vitamins B6 and B12 also contribute to the normal function of the nervous system. For melatonin the following is regulated: Melatonin contributes to the reduction of the time taken to fall asleep. These statements do not mean that a nutrient switches off the grinding; they merely describe the general contribution to normal function or to falling asleep.

Traditionally used for evening relaxation are plants such as valerian, lemon balm or lavender as tea or extract. Such applications have a long tradition but do not replace professional assessment if grinding and complaints persist. They can pleasantly accompany a calm evening ritual but are not a targeted remedy against bruxism.

Here too the following applies: a single nutrient only develops a meaningful contribution if an actual need exists. With a balanced diet, most people are well supplied with magnesium and B vitamins. Targeted supplementation can be considered in certain phases of life but does not replace the actual starting point for grinding, namely dealing with stress and sleep quality. Anyone who is unsure had better have a possible deficiency clarified by a doctor instead of dosing high on suspicion.

Honestly put into perspective

Teeth grinding can rarely be eliminated with a single remedy, because it is usually an expression of tension and sleep patterns. The most effective way is a combination of stress reduction, good sleep quality, conscious jaw relief and protection of the teeth with a splint. Food supplements can supplement a balanced diet, but they are no substitute for relaxation, healthy sleep and dental care. Realistic expectations help you to stick with it.

An important message is: protecting the teeth and dealing with the causes belong together. A splint preserves the tooth substance, while stress reduction and good sleep habits address the actual trigger. Pursuing both in parallel is usually more sensible than relying on only one measure. Many people grind more strongly in phases, for example in stressful periods of life, and more calmly when circumstances relax. It is therefore worth understanding the grinding as a signal from the body and keeping an eye on your own strain instead of just fighting the symptoms. With persistent complaints, the dental practice remains the right point of contact.

Suitable products

Anyone who wants to arrange the evening more calmly and supplement their nutrient supply will find, among other things, a magnesium complex with melatonin from us. Magnesium, according to EU claims, contributes to normal muscle function and to the normal function of the nervous system. Melatonin contributes to the reduction of the time taken to fall asleep. Such products supplement a balanced diet and good sleep habits, but they do not replace them.

Frequently asked questions (FAQ)

Why do I grind my teeth at night?

Nightly grinding is considered an unconscious reaction to stress and inner tension and is often linked to sleep quality. A lot of caffeine, alcohol, nicotine, individual medications and an unfavourable bite situation can also contribute. Usually several factors come together.

Is teeth grinding dangerous?

Mild grinding is common and not automatically in need of treatment. It becomes problematic when teeth are visibly worn, react sensitively or jaw and headaches arise. Then the dental practice should assess and protect against damage.

Does a grinding splint help?

An individually fitted bite splint can protect the teeth and cushion the forces. It does not eliminate the cause but is considered an important building block for protecting the tooth substance. Whether it fits in the individual case is decided by the dental practice.

Can magnesium help with teeth grinding?

Magnesium, according to EU claims, contributes to normal muscle function and to the normal function of the nervous system. This is no promise that the grinding stops, but it describes the general contribution of the mineral. A balanced diet usually covers the need well.

What can I do in the evening to grind less?

Sensible are relaxation rituals, breathing exercises, less caffeine and alcohol in the evening as well as a quiet, dark bedroom with fixed sleep times. A conscious check during the day not to press the teeth together additionally supports this.
