Do Your Wisdom Teeth Need Removing?

About 10 million wisdom teeth are removed in the US each year per AAOMS practice data, but only a portion are clinically necessary; many fully erupted, problem-free wisdom teeth can stay. Answer six questions about pain, eruption status, crowding, infection history, age, and x-ray history to see whether removal is likely indicated or whether monitoring is reasonable.

Last updated: May 2026

A wisdom tooth removal indication is a clinical judgment about whether a third molar should be extracted, kept and monitored, or simply re-imaged at the next visit. Likely Removal = Symptoms or Infection History + Impaction or Angled Eruption + Crowding Effect. US wisdom teeth removed annually typically target Clinically indicated cases.

What is Wisdom Tooth Removal Indication?

A wisdom tooth removal indication is a clinical judgment about whether a third molar should be extracted, kept and monitored, or simply re-imaged at the next visit. The decision rests on eruption status, symptoms, infection history, crowding effect, and age. Only an oral surgery exam with a panoramic x-ray confirms the indication.

The Formula

Likely Removal = Symptoms or Infection History + Impaction or Angled Eruption + Crowding Effect

A symptom-free, fully erupted, well-positioned wisdom tooth in an adult with a current x-ray rarely meets the threshold for removal in modern AAOMS practice guidelines.

Worked Example

A 22-year-old with intermittent pain and gum soreness around a partially erupted lower wisdom tooth, one previous infection 6 months ago, no recent x-ray.

Pain: recurring around that tooth
Eruption: partial, gum flap occasionally inflamed
Infection history: one episode
Age: 22, healing is favorable
X-ray: not recent, needed before booking surgery

📌 Verdict leans toward likely needs removal. The combination of partial eruption, recurring pain, and a prior pericoronitis episode is a textbook indication. The next step is a panoramic x-ray and surgical consult to confirm.

Why This Matters

Age affects recovery

Surgery in the late teens and early 20s heals faster and carries lower complication rates because roots are not fully developed. When removal is clinically indicated, earlier is generally easier.

Not all wisdom teeth need to come out

Modern guidelines have moved away from routine prophylactic removal of asymptomatic wisdom teeth. The case for surgery is built on specific clinical signals.

Common Mistakes

❌ Removing fully erupted, functional wisdom teeth out of habit

A symptom-free, well-positioned wisdom tooth that the patient can keep clean often does not need removal. The risks of surgery without a clear indication outweigh the benefit.

❌ Ignoring repeat pericoronitis episodes

Recurrent gum inflammation around a partial eruption rarely resolves on its own; each episode raises the risk of a more severe infection. Repeat episodes are themselves an indication for removal.

Frequently Asked Questions

Do wisdom teeth always need to be removed?

No. Fully erupted, healthy, well-positioned wisdom teeth that cause no symptoms and have no crowding effect can stay. The clearest indications for removal are recurrent infections (pericoronitis) around a partial eruption, impaction with pressure on the adjacent molar, decay that cannot be restored due to access, and orthodontic considerations. A panoramic x-ray plus clinical exam is required to confirm.

What is the best age to remove wisdom teeth?

When removal is clinically indicated, the late teens to early 20s is the most common window because root development is incomplete (lower complication rate) and healing is faster. Removal in the 30s and beyond is still safe in the hands of an experienced oral surgeon, but recovery is generally longer and complication rates rise modestly.

What are the risks of wisdom tooth removal?

Common short-term risks are swelling, bruising, and temporary trismus (limited mouth opening). Less common risks include dry socket (more common in smokers and women on oral contraceptives), nerve injury (rare; varies by tooth proximity to the inferior alveolar nerve on lower wisdom teeth), and sinus communication on upper wisdom teeth. An oral surgeon assesses these risks from the x-ray before booking.

How long does it take to recover from wisdom tooth surgery?

Most patients return to desk work within 2 to 3 days. Swelling peaks at day 2 to 3 and resolves over the following week. Soft-food eating typically lasts 5 to 7 days. Sutures, if non-resorbable, are removed at 7 to 10 days. Heavy exercise is usually deferred for the first week.
