What tool is used to rinse and dry the mouth during dental procedures?

The air/water syringe tip is specifically designed to rinse and dry the mouth during dental procedures. This instrument emits a controlled stream of air and water, allowing the dental professional to cleanse the oral cavity effectively while also helping to keep the working area clear of debris and moisture. The dual functionality of this tool—providing both rinsing with water and drying with air—makes it essential for maintaining a clear field of vision and ensuring patient comfort during procedures.

Other options may serve different purposes in the dental setting. For example, a saliva ejector is primarily used to remove saliva and fluids, while high volume evacuation (HVE) is more effective for aspirating larger amounts of liquid and debris, particularly during procedures that may produce a significant amount of blood or other fluids. An electric toothbrush, while useful for patient hygiene, does not have a role in rinsing or drying the mouth during dental procedures. Thus, the air/water syringe tip stands out as the correct choice for the specific need highlighted in the question.
