✅ What Is Bruxism?
Bruxism is a repetitive jaw activity involving tooth grinding or clenching. It is now understood as a condition related to the brain and nervous system, not a problem caused by how the teeth fit together.
Common factors linked to bruxism include:
▪️ Stress and emotional tension
▪️ Sleep disturbances
▪️ Anxiety or concentration habits
▪️ Certain medications
Because bruxism starts in the brain, there is no device that can completely stop it.

Emerging evidence links bruxism, especially sleep bruxism, to neurophysiological arousal and sleep disturbances, highlighting the need for interdisciplinary evaluation.✅ What Are Night Guards and How Do They Work?
Night guards (also called occlusal splints) are removable dental appliances worn during sleep. They are usually made of acrylic or flexible materials and are custom-made by a dentist.
Their main function is to:
▪️ Create a protective barrier between the teeth
▪️ Reduce pressure on teeth and jaw joints
▪️ Limit muscle overload during clenching
It is important to understand that night guards do not eliminate bruxism. They simply contain its harmful effects.

Night guards are often misunderstood as a treatment for bruxism. Scientific evidence shows that they act as protective tools, not curative solutions. Their value lies in preventing long-term damage, especially to teeth, muscles, and jaw joints. For best results, night guards should be used as part of a broader approach, which may include stress reduction, sleep improvement, and regular dental follow-up.
✍️ Conclusion
Night guards play a crucial role in protecting oral structures from the consequences of bruxism, but they do not cure the condition. When patients understand their real purpose, night guards become a safe and effective way to control symptoms and preserve oral health over time.
