Be sure to add a dental visit to this year's spring cleaning list. A professional dental cleaning at least twice a year can improve your oral health, reports the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing dental education.
The AGD strongly recommends that a dentist or hygienist perform a dental cleaning every six months. This professional dental cleaning reinforces the home-care oral health regimen of brushing and flossing and gives the dentist an opportunity to locate areas in the mouth that may need special attention.
People who regularly practice good oral hygiene at home with proper brushing and flossing techniques typically do not experience discomfort during a cleaning. However, those who have neglected their oral hygiene habits may experience some discomfort or sensitivity during a dental cleaning. The dentist can use a topical anesthetic before the cleaning to alleviate any discomfort.（dental x-ray machine）
