Final answer:
To address dry mouth, the patient should take actions to increase salivation, such as drinking water or using saliva stimulants.
Step-by-step explanation:
If a patient reports having a dry mouth, it may be a result of reduced salivation. Salivation is regulated by the autonomic nervous system, and reduced salivation can occur due to various reasons, such as stress or dehydration. To address dry mouth, the patient should take actions to increase salivation, such as drinking water or using saliva stimulants. Additionally, it is important for the patient to practice good oral hygiene and visit a dentist regularly to rule out any underlying dental or medical conditions that may be contributing to the dry mouth.
