Wisdom Teeth Removal: When It's Needed and the Best Age

Wisdom teeth may not need removing if they are healthy, fully grown in, positioned correctly and easy to clean. Removal is more often needed when they cause pain, infection, cysts, decay or damage to nearby teeth. Removal between about ages 15 and 22 is generally easier, with less recovery.

When removal is usually needed

  • Pain near the wisdom teeth
  • Repeated infection of the soft tissue behind the last lower tooth
  • Cysts or tumors
  • Damage to nearby teeth
  • Gum disease
  • Widespread decay

This list comes from the American Dental Association, as summarized by Mayo Clinic. [1]

Problems impacted teeth cause

  • A tooth trapped in the gum can lead to an infection or cyst that damages nearby roots or bone
  • A tooth that only partly breaks through leaves an opening for bacteria, which can cause gum disease
  • Cavities in partly erupted teeth may not be fillable, so the tooth may need to come out
  • Teeth without enough room can crowd or damage neighboring teeth
[1]

Why age matters

Removal in young adulthood, generally ages 15 to 22, tends to be safer and easier, with less recovery. The roots are not fully formed, the jawbone is less dense, and healing is faster. Some young adults have them removed before problems start for this reason. [1]

What to ask a dentist or oral surgeon

  • Are my wisdom teeth impacted, and can I see the X-ray?
  • What happens if I leave them in?
  • Will you do it, or refer me to an oral surgeon?
  • What kind of anesthesia will be used, and what does it cost?
  • How long is recovery, and what should I avoid while healing?
