Although dental examinations and dental cleanings are often performed during the same appointment, they are in fact distinct procedures.  The cleaning is exactly what it sounds like; during this procedure, a dental professional (usually a hygienist, but sometimes the dentist) will clean tartar and plaque from your teeth that may have developed since the last cleaning. They will also perform a professional flossing and polish your teeth. The dental exam is usually done after the cleaning is complete. During this part of the appointment, the dentist will examine your teeth and gums for any signs of dental disease. Some dental exams also include dental x-rays.
