Dental Chair Vs Dental Unit: What Are The Differences?

When you visit a dental clinic, you may have noticed various types of equipment and furniture. Two commonly used terms in the field of dentistry are "dental chair" and "dental unit." While these terms are often used interchangeably, there are subtle differences between them. Let's explore the difference between a dental chair and dental unit.

What Is The Dental Chair?

A dental chair is the primary piece of furniture used in a dental operatory. It is designed to provide comfort to the patient during dental procedures. The chair may be adjusted to a variety of settings, enabling the dentist easy access to the patient's oral cavity. It acts as a platform for the patient to sit or recline on during therapy.
