Endodontics

  • Focus: Concerned with the dental pulp (nerve and blood supply inside the tooth) and periapical tissues (area around the root tip).

  • Main procedure: Root canal treatment (removing infected or necrotic pulp, cleaning and shaping canals, then sealing them).

  • Goal: Save a tooth that would otherwise require extraction due to infection, trauma, or pulp necrosis.

  • Other procedures: Endodontic retreatment, apicoectomy (surgical root-end resection), pulp therapy in children.

Restorative Dentistry

  • Focus: Restores the function, integrity, and esthetics of a tooth structure lost due to caries, trauma, or wear.

  • Main procedures:

    • Direct restorations (fillings: composite, amalgam, glass ionomer).

    • Indirect restorations (crowns, inlays, onlays, veneers).

  • Goal: Rebuild the tooth structure and restore normal function and aesthetics.

  • Integration: Often complements endodontics — for example, a tooth after root canal typically needs a crown (restorative).

Key Difference

  • Endodontics deals with the inside of the tooth (pulp and root canals).

  • Restorative dentistry deals with the external rebuilding of the tooth structure.

They often work hand-in-hand:
If a tooth has deep decay reaching the pulp → endodontic treatment is performed first, followed by restorative work (like a crown) to strengthen and protect the tooth.
