Dentists
say dental cleaning should be done twice a year to prevent teeth and
gum problems. However, some experts suggest once a year is fine for
some individuals, particularly those who are not at risk of gum
disease.
The
conclusion stemmed from a study in June 2013 by University of
Michigan researchers, studying data from more than 5,100 adults.
These people were known to have visited their dentist for dental
cleaning once or twice a year for 16 years and had no history of gum
disease.
