Describe how a dental splint is utilized in TMJ treatment.

A dental splint is specifically designed to address issues related to the jaw, particularly in the context of TMJ disorders. When worn, the splint serves to keep the teeth apart, which helps to prevent contact that can lead to grinding or clenching. This benefit is crucial in relieving tension on the jaw muscles and minimizing pain associated with TMJ disorders.

Additionally, the use of a dental splint can also aid in proper alignment of the jaw, providing stability and allowing the muscles to relax. It acts as a protective barrier against the damaging effects of bruxism (teeth grinding), which is often a contributing factor in TMJ dysfunction. By focusing on these aspects, the dental splint plays a significant role in the management and treatment of TMJ disorders. This is why the choice highlighting the prevention of teeth grinding is the most accurate description of a dental splint's use in TMJ treatment.
