What fills a cleaned root canal?

Gutta-percha is a mouldable material often used as the core of a root canal filling. Dental products contain other ingredients alongside the base material. It is usually used with a sealing material called sealer; it is not a replacement nerve.

Quick answers

Is gutta-percha a medicine?

In this use it is filling material. An intracanal dressing serves a different purpose.

Does it regrow a nerve?

No. It fills the prepared canal space; it does not form new pulp.

Can it be removed later?

During necessary retreatment, filling material can often be accessed and removed. Feasibility and effort depend on the findings.

At the practice

For a personal discussion

An editorially suggested question for a discussion with Dr med dent Niusha Barahmand Pour:

How will the tooth be protected and reviewed after filling?

A root filling is planned or already present? Ask how the filling, tooth restoration and follow-up fit together.
