To prevent this, some dentists have special ventilation systems installed to get rid of bacteria floating in the air. Second, bacteria can be transferred through cuts. To protect from this type of transmission, dentists wear rubber or latex gloves to avoid any mixing of body fluids. Third, bacteria can be spread by direct contact. Dentists and staff are constantly disinfecting the surfaces in the operatories and instruments to remove bacteria.
All equipment is switched and sterilized between patients to avoid any cross contamination.
All waste is disposed of separately and in special containers in accordance with environmental regulations. If you have any questions or concerns about how bacteria is spread, be sure to Ask Your Dentist.
