Post and Core
What are post and core?
Post – is similar to a small stick that goes inside the canal. It takes support from the canal.
Core – is filling material that replaces the lost tooth structure.
To support and reinforce these two a cap/ crown is placed over it to ensure that the tooth lasts longer.
Large cavities need the removal of the infected part of the tooth leaving little sound tooth structure.
decreased water content in teeth after root canal therapy.
Reduced levels of perception of biting, chewing, or other normal activities.
Endodontically treated teeth without crowns failed at 6 times greater rate than crowned teeth
So to reinforce weak root canal treated teeth two things are a must
Placement of a post
Placement of a crown surrounding the entire tooth.
