    Root canal system sealing:

    Cones of gutta percha (a rubber compound) are used to fill in the tooth's cleansed internal space.

    The first cone placed will be one that has the exact same dimensions as the largest file that was used to clean the very end portion of the canal.

    This way, a unified mass (a single, solid piece of rubber) creates the seal at the tip of the root.

    Diagram A:

    The first gutta percha cone is dipped in sealer (a paste) and wedged into place.

    The sealer (which will set over time) fills in minute voids between the canal's walls and the cone.

  • <p>Diagram B:</p><p>Additional cones are dipped in sealer and then slipped into the canal.</p><p>The goal is simply to fill in all of the space inside the tooth.</p>
     

    Diagram B:

    Additional cones are dipped in sealer and then slipped into the canal.

    The goal is simply to fill in all of the space inside the tooth.

  • <p>As each cone is placed, the dentist will insert a tapered hand tool into the canal that helps to pack and compress the cones against each other.</p>
     

    As each cone is placed, the dentist will insert a tapered hand tool into the canal that helps to pack and compress the cones against each other.

  • <p>Diagram C:</p>Once the interior of the tooth has been filled in, the dentist will trim away any excess gutta percha.</p><p>They'll then place a temporary filling that seals and protects the work they have just completed.</p>
     

    Diagram C:

    Once the interior of the tooth has been filled in, the dentist will trim away any excess gutta percha.

    They'll then place a temporary filling that seals and protects the work they have just completed.

  • <p>To wrap things up, the dentist will take an x-ray of the tooth so they can evaluate and document their work.</p>
