Root Canal Treatment at Seoul Lab Dental Clinic (Uijeongbu)

A root canal can save a tooth that would otherwise need extraction. At Seoul Lab Dental Clinic, we use a comfort-first approach with precise anesthesia, modern shaping/cleaning techniques, and strong, natural-looking restorations—explained clearly by our English-friendly team.

What Is a Root Canal?

Inside each tooth is a small space containing nerve and blood vessels (the pulp). Decay, cracks, or trauma can inflame or infect this tissue. A root canal removes the infected pulp, disinfects the canals, and seals them so you can keep your natural tooth.

Signs You Might Need One

  • Spontaneous or lingering toothache (especially to heat)
  • Night pain or pain when chewing/biting
  • Swelling, pimple on the gums, or bad taste from one area
  • Deep decay, a large broken filling, or a cracked tooth
  • Sensitivity that doesn’t improve after a recent filling

Our Comfort-First Procedure

  1. Diagnosis & Imaging
    Detailed exam, X-rays, and bite tests to confirm the source of pain.
  2. Precise Numbing & Isolation
    Local anesthesia and a rubber dam to keep the tooth clean and dry.
  3. Cleaning & Shaping
    Removal of infected pulp, mechanical shaping, and thorough disinfection of canals.
  4. Sealing the Canals
    Biocompatible filling material placed to prevent reinfection.
  5. Core Build-Up & Restoration
    A strong internal foundation; then crown or onlay if needed to protect against fractures.
Depending on infection and anatomy, treatment may be single-visit or two-visit (with medication placed between appointments).

Will I Need a Crown?

Back teeth (molars/premolars) are more likely to crack after a root canal because they absorb heavy chewing forces. We usually recommend a full-coverage crown or onlay to prevent fractures and extend the life of the tooth. Front teeth may only need a strong filling, depending on remaining tooth structure.

Pain Management & Recovery

  • Most patients feel pressure relief soon after treatment.
  • Mild soreness when chewing is common for 2–3 days—OTC pain relief is usually enough.
  • Avoid hard chewing on the treated tooth until the final crown is placed.
  • Call us immediately if pain or swelling worsens.

When a Root Canal Isn’t Enough

  • Vertical cracks or insufficient remaining tooth can make saving the tooth unpredictable.
  • Re-treatment or apicoectomy (micro-surgery) may be discussed if a previous root canal fails.
  • If extraction is necessary, we’ll review options like implant, bridge, or partial.

FAQs

Does a root canal hurt?
With proper anesthesia, most patients feel pressure, not pain. We stop anytime you need more numbing.

How long does it take?
Typically 60–120 minutes depending on tooth type and infection; complex cases may need two visits.

How long will my tooth last?
With a proper crown, good hygiene, and routine check-ups, many root canal–treated teeth last for years.

Can I go to work after?
Yes—most patients resume normal routine the same day. Avoid chewing on the treated side until restored.

Aftercare Essentials

  • Take any prescribed meds as directed.
  • Keep the area clean; brush and floss normally (gently near the gum).
  • Return for the final crown on schedule—this step is crucial for longevity.
  • Regular check-ups protect the seal and your bite.

Pricing & Appointments

We provide transparent pricing before treatment begins and explain options (filling vs. crown, single vs. multi-visit). Our coordinators can compress appointments for travelers and help with documentation for private insurance reimbursement.
