What is Root Canal Retreatment, and When is it Necessary?

March 15, 2024

RCT or root canal treatment in Huntington Beach can save an infected tooth. However, sometimes the infection persists even after the initial procedure. In that case, your dentist may recommend root canal “retreatment” to clear away any lingering infection inside the tooth.

What Cases Call for a Repeat Root Canal Procedure?

There are a few key reasons why retreatment may be needed:

  • Infection returns due to inadequate initial cleaning of the canal system
  • New decay or damage allows bacteria to re-enter the tooth
  • A poor quality filling leaks, exposing inner tooth layers
  • Cracks form in the root or crown post-treatment
  • The tooth doesn’t heal properly and remains symptomatic

Your dentist in Huntington Beach will determine if unsatisfactory healing warrants root canal retreatment for optimal tooth restoration.

How Does a Dentist Retreat an Infected Root Canal Tooth?

Root canal retreatment follows these steps:

  • Old crown and core buildup are removed to access the root canal space.
  • Previous canal filling material is extracted.
  • The canal is flushed and cleaned thoroughly.
  • Canal irregularities are sealed.
  • The tooth is re-filled and sealed with bonded composite.
  • A new core and crown are fabricated and cemented for full coverage.

Advanced techniques like microscopy and ultrasonics help dentists better see and access all canal anatomy. Your tooth’s prospects improve greatly with modern retreatment.

What New Technology Improves Retreatment Success Rates?

Dentists in 92648 now use operating microscopes and micro-instruments to perform meticulous root canal retreatments. The microscope provides magnified visualization for more precise, complete cleaning. Specialized ultrathin files allow better access to tiny, hard-to-reach canal anatomy. Digital radiography also gives enhanced diagnostic information.

These advances make root canal retreatment more precise. Teeth requiring retreatment have much better clinical outcomes and survival rates today.

What Alternatives Exist if Infection Persists After Retreatment?

If infection remains even after a repeat root canal, your dentist may recommend:

  • Root resectioning surgery – Removing infected root tip(s)
  • Tooth extraction – Removing the tooth entirely
  • Dental implant – Replacing the tooth with an implant

However, with current techniques, most cases respond successfully to retreatment. Your dentist near you will discuss options if your tooth fails to heal.

How Can Proper Crown Placement Prevent Retreatment Needs?

If you get a full-coverage crown right after initial RCT, you can prevent issues that require retreatment:

  • It seals the access hole to prevent recontamination.
  • It protects the tooth from fracture.
  • It resists decay that could penetrate the root.

Talk to your dentist about placing a durable, well-fitted crown after your root canal for the best results.

When is Root Canal Retreatment Necessary?

Retreatment is mandatory if your tooth remains:

  • Severely symptomatic – pain, swelling, sensitivity
  • Non-functional – unable to bite/chew
  • Infected – draining pus, abscess, fistula

Leaving these severe problems means eventual tooth loss. However, after initial treatment, retreatment can often be avoided with prompt care of cracks, decay, crowns, and minor symptoms.
