Daytime bruxism: tips and methods to stop clenching

Clenching your teeth during the day, often without even realising it, is more common than it may seem. Unlike sleep bruxism, daytime bruxism occurs while you are awake, which has one important advantage: because it can become more conscious, the habit can be retrained. In this article, we explain how to recognise it, why it happens and which methods can help you stop clenching.

What is daytime bruxism and how is it different from sleep bruxism?

Daytime bruxism is the habit of clenching the teeth, rather than grinding them, while awake, usually unconsciously or semi-consciously. It often occurs during periods of concentration, stress or tension and mainly involves static clenching, usually without any noticeable sound.

The key difference compared with sleep bruxism is control. At night, people may clench or grind their teeth without any voluntary control, which makes it more difficult to detect and stop. During the day, however, it is possible to become aware of the habit and correct it. For this reason, although daytime bruxism can also cause tension and tooth wear, it tends to respond particularly well to habit retraining.

How to tell if you clench your teeth during the day

Many people do not realise that they are clenching until discomfort begins to appear. Learning to observe your own habits is the first step.

Physical signs: jaw tension, pain and fatigue

Pay attention to these signs, particularly towards the end of the day: a tight or heavy jaw, fatigue when chewing, headaches, neck pain or pain around the temples, or discomfort in front of the ears. If the jaw muscles feel tired or overworked without an obvious reason, this may be a sign that you have been clenching.

When are you most likely to clench without realising it?

Daytime clenching often occurs in very specific situations: while working at a computer, driving, using a mobile phone, during periods of intense concentration or when experiencing stress or emotional tension. Identifying when it happens is essential if you want to start correcting the habit.

Why does daytime bruxism occur?

In most cases, there is no single cause, but rather a combination of factors. One of the main factors is stress and anxiety, which may translate into muscle tension and clenching. Other factors include concentration — we often clench when making an effort — neck tension and poor posture in front of screens, as well as certain habits and stimulants, such as excessive caffeine intake. Understanding that daytime bruxism is often multifactorial makes it easier to address it from several angles.

How to relieve daytime bruxism: methods that can help

This is the most important part. Because daytime bruxism happens while you are awake, it can often be improved considerably with consistent habit retraining. These are some of the most useful methods for reducing clenching and preventing it from becoming habitual.

Retrain the resting position of your jaw

This is the foundation of habit retraining. At rest, the natural position of the mouth is with the lips together and the teeth apart, without contact between the upper and lower teeth, while the tongue rests gently against the palate. Many people mistakenly believe that their teeth should be touching at rest. They should not. Try to internalise this position and return to it whenever you notice that you are clenching.

Train your awareness with reminders

Because the habit often happens unconsciously, external reminders can help you catch yourself clenching. Place Post-it notes or visual reminders on your computer, in the car or on your phone, or set regular alarms or reminders. Each time you see the reminder, check whether your teeth are touching. If they are, consciously relax your jaw. Over time, this correction can become more automatic.

Exercises and stretches to relax the jaw

These can help relieve accumulated tension. Perform gentle opening and closing movements of the mouth without forcing the jaw, and try a gentle self-massage of the masseter muscle, located in the cheek near the angle of the jaw, using small circular movements with your fingertips. Do this gently and stop if you experience pain.

Stress management and active breaks

Because stress is an important trigger, managing it can be helpful. Introduce active breaks during the working day, practise slow, deep breathing during periods of tension and consider relaxation techniques. Reducing your overall level of tension may also help reduce clenching.

Review your posture and ergonomics

Posture can have more influence than it may seem. Holding the head forward while using screens places additional strain on the neck and may contribute to jaw tension. Adjust the height of your screen, keep your back upright and shoulders relaxed, and pay attention to the ergonomics of your workstation.

What to avoid if you have daytime bruxism

Some everyday habits can worsen daytime bruxism without you being aware of it. It is advisable to avoid:

• Chewing gum constantly, as this keeps the jaw muscles continuously active.
• Biting objects such as pens, fingernails or pen caps.
• Excess caffeine and other stimulants.
• Using teeth clenching as an “effort gesture” when lifting weights or concentrating.

When self-help measures are not enough: treatments for bruxism

Habit retraining is the basis of management and may be sufficient in many cases. However, when bruxism is more intense or is accompanied by pain or tooth wear, professional treatment may be required:

• Occlusal splint: although it is more commonly associated with sleep bruxism, it may be particularly useful if you also clench or grind your teeth at night, as it helps protect the teeth and manage excessive loading.
• Neuromodulators for bruxism: in selected cases involving masseter overactivity, persistent pain or marked muscle tension, they may be used to reduce excessive muscle contraction, always following medical assessment.
• Professional assessment and follow-up, combining these measures with habit correction and stress management when appropriate.

When should you see a specialist?

It is advisable to seek an assessment if you experience persistent jaw pain, visible tooth wear or frequent headaches, or if the problem begins to affect your daily life, including sleep, concentration or quality of life. There is no need to wait until significant tooth wear develops: addressing the problem earlier may help prevent further consequences.

At Face Clinic, our specialist team assesses each case individually to identify the factors involved and recommend the most appropriate bruxism treatment for each patient. If you recognise several of the signs described above, you can request an individual assessment.
