Night Guard Treatment: A Protective Guide for Teeth Grinding and Bruxism

A night guard is a protective appliance used to prevent damage to the jaw joint in cases of teeth grinding and clenching (bruxism). It reduces jaw pressure and pain, prevents tooth wear, and helps avoid potential tooth loss. However, proper use is crucial—incorrect use may cause harm to the jaw joints.

Patients using a night guard must follow hygiene rules. It should be cleaned daily and stored securely in its case to avoid contamination or damage.

What Is a Night Guard?

The primary purpose of a night guard is to address issues like bruxism and teeth clenching. It is a hard, transparent appliance worn during sleep. It is typically fitted over the upper or lower teeth and is designed to protect the temporomandibular joint (TMJ).

This treatment relaxes jaw muscles, prevents tooth wear, and reduces pressure on the TMJ. Night guards are custom-made based on a mold taken from the patient’s teeth and provide both short- and long-term benefits when used regularly.

Difference Between a Splint and a Night Guard

Both splints and night guards serve to protect the mouth. However, they differ in purpose, material, and areas of application. These differences become more apparent depending on the treatment goals.

Why Is a Night Guard Worn?

The purpose of wearing a night guard is to protect oral health and maintain jaw function. It is primarily used to prevent teeth grinding and clenching during sleep. As a result, jaw pain is reduced, and long-term damage can be avoided.
