What is the purpose of the saliva ejector during dental procedures?

The primary purpose of the saliva ejector during dental procedures is to help control moisture and debris in the area. By creating a gentle suction, the saliva ejector efficiently removes excess saliva, blood, and other fluids that can obstruct the dentist's view and hinder the procedure. This is particularly important during various treatments, such as fillings and crown preparations, where maintaining a clean and dry field is crucial for optimal bonding and treatment success. Additionally, the saliva ejector helps create a more comfortable experience for the patient by minimizing the accumulation of fluids in the mouth, allowing for a smoother flow of the procedure.

While suctioning blood can be a part of its function, the main goal is to manage moisture overall. The saliva ejector does not irrigate the surgical site, which is typically done with a separate tool, nor is it used specifically to dry a tooth before filling, as that might require air or specific drying agents.
