When was your last dental cleaning? If you can’t answer this question quickly, the answer is “I don’t remember”, or it was so long ago that you don’t know, it’s time to go to the dentist for a general evaluation and teeth cleaning. Dental cleaning is a minimally invasive procedure in which dental plaque and dental calculus (tartar) are removed using ultrasound and other polishing techniques from dental surfaces. If done regularly, it prevents periodontal problems, and gives your dentist the opportunity to check that the rest of your teeth and oral tissues are good and healthy.
