i never went to the dentist in over 21 years. I then decided to take better care of my teeth and went and had all teeth cleaned  and checked for cavities.  I had 1 cavity after 21 years.  now i have been going to the dentist twice a year for cleaning and checkup.   Last visit revealed 6 cavities.   How do i go from 1 cavity in 21 years to 6 cavities in about 21/2 years ?
