The treatment of bruxism is based on protecting the teeth, reducing the strain on the masticatory muscles, and managing the associated symptoms of teeth grinding. The most common and effective forms of treatment are a bite splint, physical therapy, and lifestyle changes. In more severe cases, botulinum toxin treatment can reduce the activity of the masticatory muscles and relieve pain. Treatment is always selected on an individual basis according to symptoms and underlying causes.

What is bruxism:
Bruxism refers to the involuntary clenching or grinding of the teeth, often during sleep.

Who is this treatment suitable for:
People who experience jaw pain, tension in the chewing muscles, headaches, or tooth wear.

Key limitation:
Bruxism generally cannot be completely eliminated; instead, treatment focuses on managing symptoms and reducing adverse effects.

Introduction

Bruxism is a common but often unnoticed condition. It can put strain on the jaw muscles, jaw joints, and teeth long before symptoms are recognized.

Many people seek treatment only after experiencing pain, tooth wear, or headaches. By this stage, bruxism has often been going on for a long time.

There is no single solution for treating bruxism. It can be caused by a variety of factors, such as stress, sleep disorders, or muscle strain. For this reason, treatment is tailored to each individual.

This page provides an overview of the main treatment options for bruxism and when each is used.

A Brief Overview of the Treatment of Bruksism

The treatment of bruxism is based on protecting the teeth and reducing muscle tension
A bite splint is the most common and primary form of treatment
Physical therapy can reduce tension in the jaw muscles
Stress management supports treatment, particularly in stress-related bruxism
Botox treatment can reduce the activity of the jaw muscles in severe cases

Treatment of bruxism and the masticatory muscles: An Illustrated Guide — Treatment for bruxism focuses on protecting the teeth and reducing the strain on the masticatory muscles.

Why is treatment for bruxism necessary?

Bruxism can cause a variety of symptoms and structural changes, even though it is not always immediately noticeable.

Tooth wear and chips
Load and stiffness of the temporomandibular joint
Pain and fatigue in the masticatory muscles
Headache, especially in the temple area

Symptoms often develop gradually. Many people don’t realize they have bruxism until the pain or tooth wear has already progressed.

Jaw pain as a symptom of bruxism — Jaw pain and muscle tension are typical symptoms of bruxism.

If left untreated, bruxism can worsen over time and lead to permanent changes in the teeth and temporomandibular joint. The goal of treatment is to reduce the strain and prevent further damage.

According to the Finnish Current Care Guidelines, the treatment of bruxism is primarily based on managing symptoms and reducing adverse effects, not merely on eliminating the grinding itself.

Treatments for bruxism

Bite splint (most common treatment)

A mouthguard is the primary treatment for bruxism. It is typically worn at night to protect the teeth and reduce strain on the jaw muscles.

Bite rail

protects teeth from wear and chipping
reduces the force of the bite on the teeth
can relieve muscle tension and pain

A bite splint for the treatment of bruxism — A mouthguard is the most common treatment for bruxism and protects the teeth from the stress caused by grinding.

A bite splint does not eliminate the underlying cause of bruxism, but it significantly reduces the strain on the teeth and temporomandibular joint. For this reason, it is often the first treatment recommended.

According to current treatment guidelines, a bite splint is used especially when bruxism causes tooth wear or muscle symptoms.

Physical Therapy and Muscle Care

Bruxism is often associated with overuse of the jaw muscles. This can lead to muscle tension, pain, and restricted jaw movement.

Treatment options:

Muscle relaxation and massage
Stretching exercises for the jaw muscles
Improving jaw joint mobility

Physical therapy can reduce muscle tension and relieve pain, especially when the symptoms are muscle-related. However, the treatment does not eliminate bruxism itself, but rather serves as part of a comprehensive treatment plan.

In some cases, guided exercises and muscle care can also help identify harmful habits related to biting, such as constantly clenching your teeth during the day.

Lifestyle changes

Bruxism is often linked to stress, sleep issues, and nervous system strain. Therefore, lifestyle changes are an important part of treatment, especially when there is no clear structural cause underlying the condition.

Lifestyle changes:

Reducing stress and promoting recovery
Improving sleep quality
Recognizing and Reducing Daytime Teeth Clenching

Stress can increase the activity of the jaw muscles and worsen teeth grinding, especially during sleep. For this reason, relaxation techniques, regular sleep, and stress management can help reduce symptoms.

Lifestyle changes alone are usually not enough to treat severe bruxism, but they complement other forms of treatment and can reduce the recurrence of symptoms.

Botox treatment for bruxism

The masseter muscle, or chewing muscle, in bruxism — The masseter muscle, also known as the chewing muscle, plays a key role in bruxism and its treatment.

Botulinum toxin can be used to treat bruxism when there is significant overuse of the masticatory muscles and other treatments are insufficient.

The treatment specifically targets the masseter muscles, which are responsible for biting force. Botulinum toxin reduces muscle activity by weakening the neuromuscular junction.

Botulinum treatment

reduce the contractile force of the masticatory muscles
can relieve muscle pain
can reduce teeth grinding

Botulinum toxin treatment for the masseter muscle in the management of bruxism — Botulinum toxin treatment can reduce the activity of the jaw muscles and alleviate the symptoms of bruxism.

The effects usually begin within a few days and last an average of 3–6 months. However, the treatment does not address the underlying cause of bruxism but primarily alleviates the symptoms.

Research evidence suggests that botulinum toxin may reduce muscle activity and pain in bruxism. However, the evidence is mixed, and the treatment is not suitable for all patients.

When is botulinum toxin treatment considered?

Botulinum toxin treatment may be considered when bruxism causes significant symptoms and primary treatments do not provide sufficient relief:

The masticatory muscles are clearly overworked or enlarged
Back pain or muscle fatigue is persistent
A bite guard is not enough to relieve symptoms
Tooth wear continues despite treatment

Treatment decisions are made on an individual basis based on symptoms, findings, and previous treatments. Botulinum toxin treatment is not the primary treatment; rather, it is generally used as a complementary option.

Before starting treatment, potential underlying causes of bruxism, such as stress, sleep disorders, and factors related to bite alignment, are assessed.

Can bruxism be cured?

Bruxism usually cannot be permanently cured, but its symptoms can be effectively managed. The goal of treatment is to reduce strain on the masticatory muscles, protect the teeth, and relieve pain.

Bruxism is often a multifactorial condition influenced by factors such as stress, sleep, and nervous system regulation. For this reason, a single treatment usually does not completely eliminate the grinding itself.

Symptoms can be significantly alleviated with the right treatment
Tooth wear can be prevented
Muscle pain and tension can be reduced

In some cases, bruxism may resolve on its own, for example, as life circumstances stabilize or stress levels decrease. For others, the symptoms may be long-term and require ongoing treatment.

The key is to assess your own situation and choose the appropriate treatment options accordingly.

When to seek treatment

You should seek treatment for bruxism if your symptoms are recurring, worsen over time, or interfere with your daily life:

Jaw pain or muscle tension is persistent
Teeth wear down or chip
Headaches are common, especially in the mornings
My jaw feels stiff or restricted

Early diagnosis is important because, if left untreated for a long time, bruxism can cause permanent changes to the teeth and the temporomandibular joint.

Seeking treatment does not mean receiving a specific treatment, but rather having the situation assessed and selecting the appropriate forms of treatment.

Risks and Limitations

When treating bruxism, it is important to understand that not all treatments work for everyone. Treatment is based on managing symptoms, not on a single solution.

A single treatment usually does not eliminate the underlying cause of bruxism
Symptoms may recur over time
The response to treatment varies from person to person

For example, a bite guard protects the teeth but does not necessarily reduce muscle activity. Similarly, Botox treatment can reduce muscle tension, but its effect is temporary.

Long-term care often requires a combination of various treatment methods as well as ongoing monitoring of the patient's condition.

Research evidence supports the use of various treatment methods for symptom management, but the exact mechanism underlying bruxism is not fully understood. This also affects the predictability of treatment outcomes.

Frequently Asked Questions About the Treatment of Bruxism

What is the best treatment for bruxism?

The best treatment depends on the cause and symptoms of bruxism. In most cases, a mouthguard is the primary treatment, but many people also need physical therapy or other forms of support.

Does a bite splint help with bruxism?

A mouthguard protects the teeth and can reduce muscle strain. However, it does not address the underlying cause of bruxism; rather, it serves as a preventive treatment.

Can bruxism go away on its own?

In some cases, bruxism may subside without treatment, especially if the underlying stress or strain is reduced. However, the symptoms may also persist.

How can I tell if I'm grinding my teeth?

Typical symptoms include jaw pain, morning headaches, tension in the chewing muscles, and tooth wear. These symptoms often develop gradually.

When is botulinum toxin treatment used for bruxism?

Botox treatment is usually considered when the jaw muscles are severely overworked and other treatments have not provided sufficient relief.

Is Botox a permanent solution?

No. The effects of Botox treatment usually last 3–6 months, after which the treatment can be repeated if necessary.

Can stress make bruxism worse?

Yes. Stress can increase the activity of the jaw muscles and make teeth grinding worse, especially during sleep.

When should you seek treatment for bruxism?

You should seek treatment if your symptoms are recurring, getting worse, or causing pain, tooth wear, or headaches.

Can bruxism cause permanent damage?

Yes. Prolonged bruxism can wear down the teeth, strain the jaw joint, and cause long-term muscle pain.
