Dental treatment. Dentist using handheld tools during treatment of a patient. The pink tube (with grey cable) is a suction tube that is used to remove saliva and debris from the patient's mouth. The dentist is wearing a mask and gloves to prevent cross-contamination of bacteria. Typical handheld dental tools are mirrors, tongue depressors and scrapers. These are used to examine the patient's teeth, probe the teeth for areas of decay, and scrape the teeth clean of accumulated material such as tartar.
