decayed part of the tooth is removed using a dentist’s drill and is filled in

Periodontal disease also called Periodontitis or Gum Disease is a
bacterial infection that destroys the supporting structures holding the
teeth in their place. The main etiologic agent is bacterial plaque. Left
untreated, this disease can lead to bone grafts, gum grafts, and
ultimately tooth loss. Some of the early warning signs are slight
bleeding when you brush, gums are getting softer and are changing
their colour from pink to red.
Thrush of mouth is a yeast infection that may appear in an
individual’s mouth that is caused by uncontrollable growth of an
organism known as Candida albicans. One of the leading and primary
reasons of oral thrush is gorge of antibiotics. Candidiasis is not
generally a critical condition. The exception is that it enters the blood
and then multiplies in organs particularly in people with weakened
immune systems. For this reason an antifungal prescription can be
administered.
The best way to prevent dental diseases is to practice good oral
and to make your check up regularly.
