Cleanings:

A "cleaning" is considered a routine hygiene procedure.  It is recommended that you have a cleaning once every six months, though some special cases may require more frequent visits (periodontal cleanings).  The process involves the removal of soft (plaque) and hard (tartar) material from your teeth.  The dentist or hygienist will also floss and polish your teeth to remove stains.  Fluoride therapy is usually recommended at your cleanings as well.  In general a cleaning appointment should be a pleasant experience.  If you find that your routine cleaning visits are uncomfortable or even hurt, notify your dentist immediately.  You may be in need of additional therapy.  Cleanings should not hurt!
