Do you wake up in the morning with jaw pain, sensitive teeth, or a headache? You may be suffering from bruxism — the unconscious clenching or grinding of teeth. Many people are unaware of it for a long time, yet it can gradually cause tooth wear, damaged fillings, dental crowns, or aesthetic dental veneers.
In this article, you will find out how to recognise bruxism, why it occurs, what consequences it can have, and what treatment options modern dentistry offers.
What Is Bruxism?
Bruxism is a repetitive activity of the jaw muscles, involving clenching or grinding of the teeth. It is not a disease in itself, but a condition that — when persistent — can negatively affect the teeth and the entire chewing apparatus.
There are two main types:
- Sleep bruxism — occurs during sleep and the person is usually unaware of it. Partners often notice it first when they hear the grinding.
- Awake bruxism — occurs during the day, most commonly during stress, periods of concentration, computer work, or driving.
How to Tell Whether You Grind Your Teeth
Bruxism can manifest in a variety of ways. The most common signs include:
- pain or fatigue in the jaw muscles upon waking,
- headaches, particularly around the temples,
- worn or shortened front teeth,
- increased tooth sensitivity to cold,
- clicking or popping in the temporomandibular joint (TMJ),
- chipped dental fillings, dental crowns, or dental veneers,
- indentations of the teeth on the tongue or the inner surface of the cheeks.
If your partner tells you that you grind your teeth at night, this is one of the classic signs of sleep bruxism. With awake bruxism, people often notice that they are clenching their teeth hard without realising it — during work or stressful situations.
Why Is Bruxism a Problem?
During normal chewing, the forces acting on the teeth are significantly lower than during prolonged clenching. When this occurs regularly, it gradually places excessive strain on the teeth, jaw muscles, and the temporomandibular joint (TMJ).
Long-term bruxism can lead to:
- wear of the tooth enamel,
- small cracks developing in the teeth,
- damage to dental fillings, dental crowns, or dental bridges,
- chipping of composite and ceramic dental veneers,
- wedge-shaped lesions at the cervical areas of the teeth,
- overloading of dental implants,
- TMJ pain and restricted mouth opening.
For patients planning aesthetic treatment — such as dental veneers — it is particularly important to identify bruxism beforehand. Without adequate protection, it can significantly shorten the lifespan of aesthetic restorations.
How Is Bruxism Treated?
There is currently no treatment that eliminates bruxism entirely. The goal of therapy is primarily to protect the teeth from its effects and, where possible, to reduce the intensity of clenching.
Stabilising Splint
The standard solution is a custom-made stabilising (Michigan) splint. It is fabricated from precise impressions of the patient’s teeth and, when worn during sleep, helps to distribute chewing forces evenly while protecting the teeth from further wear.
It is important to note that a splint does not cure bruxism. Its primary role is to protect the teeth, fillings, crowns, and dental veneers from damage.
Inexpensive universal splints available online do not offer the same precision or effectiveness and can, in some cases, actually worsen the problem.
Habit Modification
For awake bruxism, conscious monitoring of clenching habits, relaxation techniques, mindfulness, or cognitive behavioural therapy can be helpful. As daytime bruxism is often linked to stress, addressing its underlying causes may also form part of the treatment approach.
Botulinum Toxin
In some patients with significant overloading of the jaw muscles, botulinum toxin injections may be considered. This temporarily reduces the force of the masticatory muscles and can provide relief, particularly in more severe forms of bruxism.
Frequently Asked Questions
Will a splint cure bruxism?
No. A stabilising splint protects the teeth from excessive loading, but it does not address the underlying cause of bruxism.
How do I know if I have bruxism?
Typical signs include morning jaw pain, tooth sensitivity, worn front teeth, TMJ clicking, or repeated damage to dental fillings. A definitive diagnosis is made by a dentist following a clinical examination.
Is a splint covered by health insurance?
Custom-made Michigan splints are not routinely covered by public health insurance in the Czech Republic (where healthcare is funded through statutory health insurance funds). The exact cost will be discussed during your initial consultation.
Conclusion
Bruxism is a very common condition that can progress for a long time without causing obvious symptoms. Nevertheless, it gradually places strain on the teeth, fillings, crowns, dental veneers, and the TMJ. The earlier it is identified, the greater the chance of preventing more extensive damage.
