Even if root canal treatment was successful, improper oral hygiene and lack of care of dental crowns can lead to the re-emergence of infection and retreatment of root canals. To avoid this unpleasant situation Endodontists in Tennessee developed easy roles, but they guarantee long lifetime of the dental crowns:
rinse your mouth after every meal,
use dental floss,
brush the teeth at least twice a day, after meal (in the morning and before going to bed),
in the contact areas with the gum it is necessary to use special tooth brushes,
do not chew on crown solid food, as this may easily lead to inconsistency of the crown.
