What is the typical lifespan of a post and core?

According to a study, teeth restored with metal post and cores exhibited an average survival period of 13.5 years from post insertion to tooth extraction. While there isn't a comparable study for fiber posts, it is generally believed that they have a longer lifespan than their metal counterparts. This is attributed to the clear advantages of fiber posts, such as being non-corrosive and having a similar elastic modulus to dentin, making them more compatible. The retention of metal posts is influenced by factors such as post surface area, shape, and the type of cement used.

Is a post and core procedure necessary?

As a general guideline, if more than half of the original crown portion of a tooth (the visible part above the gum line) is lost, a post is typically required to provide support for anchoring the core to the tooth. If more than half of the tooth's crown remains, a core alone may be sufficient.

How much of the tooth is required for a crown?

A crown becomes necessary when a tooth is compromised by a significant cavity, a root canal, or a large filling that occupies more than 3/4 of the tooth's size.
