An oral suction machine is essential in dental clinics for removing fluids like saliva, blood, or debris from a patient's mouth during treatment. They come in various types, including portable models for mobile clinics or smaller spaces. These machines typically use suction pumps and are designed to be efficient, quiet, and easy to maintain. Some models also have built-in filtration systems to ensure hygienic operation. For more information, check out different options available on dental supply websites.
