Why International Patients Choose Yonsei Heal Dental at Seoul

Supernumerary Wisdom Tooth


A supernumerary wisdom tooth is an extra wisdom tooth that develops beyond the normal four third molars. This rare condition can cause crowding, discomfort, and potential dental complications if left untreated.


At Yonsei Heal Dental Clinic, our oral surgeons provide safe, precise diagnosis and removal of supernumerary wisdom teeth using advanced imaging and minimally invasive techniques.


What is a Supernumerary Wisdom Tooth?
Normally, adults have four wisdom teeth (one in each corner of the mouth).
A supernumerary wisdom tooth refers to:

  • Fifth or even sixth molar forming behind normal wisdom teeth
  • May be fully erupted, partially erupted, or impacted in the bone
  • Can develop in one or multiple quadrants of the mouth


Why Removal is Important
Leaving a supernumerary wisdom tooth untreated can lead to:

  • Crowding or shifting of adjacent teeth
  • Gum infection (pericoronitis) due to difficult cleaning
  • Damage to neighboring molars or dental roots
  • Cyst formation or jawbone issues
  • Pain, swelling, or bite problems


Symptoms to Watch For

  • Pain or swelling behind the last molar
  • Food trapping and gum inflammation
  • Difficulty cleaning the back of the mouth
  • Recurring infections or bad breath
  • Feeling of “pressure” in the jaw


Step-by-Step Procedure

  1. Consultation & 3D CT Scan – Precise imaging to locate extra tooth and nearby nerves
  2. Treatment Planning – Customized approach for safe removal
  3. Local Anesthesia or Sedation – Ensures pain-free surgery
  4. Surgical Removal – Minimal incision, careful extraction

Aftercare Tips

  • Apply cold compress during first 24 hours to minimize swelling
  • Eat soft foods (soups, mashed potatoes, yogurt) for a few days
  • Avoid smoking, alcohol, and vigorous rinsing to prevent dry socket
  • Take prescribed medication as directed
  • Return for follow-up and suture removal
