Root canal treatment

Root canal treatment is done when the nerve of a tooth is inflamed or directly exposed.
The nerve tissue is removed and the inside of the tooth is disinfected
so that the tooth can keep working.

  • Treatment time

    About 60 minutes

  • Anesthesia

    Local anesthesia

  • Number of visits

    3 ~ 4 visits

  • Average duration

    3 weeks ~ 1 month

  • Pain & bleeding

    None

Treatment needs to remove
the source of infection thoroughly.

Steps of root canal treatment

  • 01

    We make an accurate diagnosis
    and set up a treatment plan.

  • 02

    After anesthesia we remove the source of
    infection and expose the nerve.

  • 03

    We remove the infected nerve and
    tooth tissue and disinfect
    the root canal.

  • 04

    Once disinfection is finished and
    there are no clinical symptoms, the canal
    is filled with dental material.

  • 05

    Suitable prosthetic treatment then
    restores the function of the tooth.

Why a crown is needed after root canal treatment

Root canal treatment begins by removing the infected nerve and dentin, fills the space where the nerve was with a substitute material,
and finishes by filling the empty space in the crown of the tooth with a hard dental material.

Unlike an untreated tooth, a tooth that has had root canal treatment no longer receives nutrients through the canal,
so its enamel and dentin weaken and it can fracture.
Root canal treatment also involves removing tooth structure, which makes the tooth structurally less able to withstand chewing forces.
A crown is therefore placed alongside it to protect the weakened tooth and help prevent the natural tooth from fracturing.

What is prosthetic treatment (a crown)?

“The damaged part of the tooth is filled with a hard dental material,
the tooth is then trimmed around its circumference as much as needed,
and a dental prosthesis is placed over the whole tooth.”

A damaged tooth is likely to split or crack under chewing forces,
so prosthetic treatment wraps the tooth to preserve its remaining structure.
Even without root canal treatment, a badly damaged tooth needs prosthetic treatment
to preserve the natural tooth.

Prosthetic (crown) treatment —
have you been putting it off because
the procedure or the cost worries you?

With prosthetic treatment in particular, leaving it undone makes it more likely that
the natural tooth will fracture or split, so it needs to be covered with a suitable material.

To keep a natural tooth and use it for a long time,
it matters a great deal to make and bond a well-fitting prosthesis at the right time.

Types of
prosthetic treatment

  • Gold crown

    It is biocompatible and strong, and because it is metal it does not chip the way brittle materials do.
    The minimum thickness the material needs for stability is small, so less tooth structure
    has to be removed than with other materials, but it is less esthetic.

  • Zirconia crown

    Like gold, this material is biocompatible and strong.
    It also conducts heat poorly, so teeth feel less sensitive with hot
    or cold food, and its color is close to a natural tooth, which is why it is the material
    most commonly used these days.

  • All-ceramic crown

    This material can reproduce the translucency of a natural tooth, so it looks esthetic and natural.
    It is well suited to designing the color, shape and alignment of a tooth and is
    used mainly for esthetic restorations on front teeth.
