Wisdom teeth: removal is not automatic

A lot of people assume wisdom teeth must come out. Not true. Some wisdom teeth erupt normally, function fine, and can be kept clean.

The real question is: are they stable, healthy, and maintainable long-term?

When wisdom teeth are more likely to cause problems

Wisdom teeth are the last teeth to erupt. Common issues include:

• not enough space (partial eruption)
• awkward angle (impaction)
• difficulty cleaning (recurrent inflammation)
• deep gum pockets trapping food and bacteria

The classic problem: pericoronitis

Pericoronitis is inflammation/infection around a partially erupted wisdom tooth. Signs include:

• swelling around the tooth
• pain when chewing
• bad taste or discharge
• difficulty opening the mouth
• swollen lymph nodes

If it’s recurring, the long-term fix is often removal because the anatomy keeps trapping bacteria.

Reasons removal is commonly recommended

• recurrent infection or inflammation
• decay in the wisdom tooth or the tooth in front
• gum disease around the area
• cyst formation (less common, but important)
• damage to adjacent teeth
• pain and functional issues

Removal is a risk-benefit decision. A responsible clinician discusses both.

Reasons wisdom teeth can sometimes stay

• fully erupted in a good position
• easy to clean
• no decay and healthy gums
• not damaging the tooth in front
• stable on X-ray

If they can be maintained, keeping them can be fine.

What an assessment involves

A proper assessment includes:

• symptom history (pain, swelling, frequency)
• clinical exam (gums, pockets, accessibility for cleaning)
• imaging if needed (often an OPG) to assess position and risk factors
• discussion of options: monitor vs remove, and expected pathway

What to do if you’re in pain right now

If you have swelling, fever, severe pain, or difficulty opening your mouth, don’t wait weeks. Call for triage. Early care reduces complications.
