Which of the following does not help alleviate the symptoms of trismus?

Oraverse is a medication specifically designed to reverse the effects of local anesthetic agents, particularly for patients who may experience prolonged numbness after dental procedures. While it is effective for hastening the recovery from anesthesia, it does not directly address the symptoms of trismus, which is characterized by restricted ability to open the mouth due to muscle spasms or stiffness.

In contrast, applying heat for a set duration can help relax the muscles and increase blood flow to the affected area, assisting in alleviating discomfort and improving mobility. Utilizing warm saline rinses may also contribute to symptom relief through soothing effects and promoting hydration in the oral cavity. Muscle relaxants are pharmacological agents that can reduce muscle tension and spasms, offering further relief for trismus.

The other options directly contribute to relieving the symptoms associated with trismus, while Oraverse does not provide symptomatic relief for this specific condition.
