As Periodontists, we strive to do everything possible to save teeth.  Nothing functions better than a natural tooth.  However, some teeth can not be saved.  This could be due to a number of factors of which include – severe cavities, fractures, infection, bone loss, failed root canals, trauma etc.  Before the extraction is carried out, we always discuss with the patient in detail, what they would like the tooth to be replaced with (implant, bridge etc.)
