What wisdom teeth are
Wisdom teeth, clinically called third molars, are the last set of teeth to erupt, usually between ages 17 and 25. Many people don't have enough space in their jaw to accommodate them, which is why so many of us end up with problems. Some patients have all four wisdom teeth come in cleanly with no issues. Others have all four impacted or causing problems.
When wisdom teeth can stay
If your wisdom teeth meet all of these criteria, they often don't need removal:
- Fully erupted and aligned correctly with the other molars
- Functional, they participate in chewing
- Reachable by toothbrush and floss for proper cleaning
- No history of gum inflammation or decay on or around them
- X-ray shows no cysts, root issues, or impact on adjacent teeth
When removal is recommended
Wisdom teeth are typically extracted when they're impacted (stuck partially or fully under bone or gum), crowding other teeth, causing infections, decaying because they can't be cleaned, or showing signs of forming cysts. Partial impactions are particularly problematic, the gum flap over a partially erupted tooth traps food and bacteria, often leading to repeated infections called pericoronitis.
Why earlier is often easier
When wisdom teeth are extracted in late teens or early twenties, the roots are typically not fully formed and the surrounding bone is more flexible. Healing is faster, risk of nerve injury is lower, and recovery time is shorter. After age 30, wisdom tooth extraction becomes progressively more complex and recovery longer. This is part of why many practices recommend prophylactic removal in young adulthood even when problems aren't yet present.
How we evaluate yours
At your evaluation, we take a panoramic X-ray (and sometimes a CBCT for complex cases) to see how your wisdom teeth are positioned, where the roots are relative to the inferior alveolar nerve, and how they're affecting adjacent teeth. From there, we recommend a clear path: keep and monitor, extract, or refer to an oral surgeon for complex cases.
Risks of leaving impacted wisdom teeth in place
Some wisdom teeth can stay. Others develop complications over years that are easier to prevent than treat. The risks we weigh during your consultation:
- Pericoronitis, recurring infection of the gum flap over a partially erupted wisdom tooth
- Decay on the back of the second molar (the tooth in front of the wisdom tooth)
- Cyst formation around impacted wisdom teeth (rare but can damage bone)
- Crowding of the front teeth as wisdom teeth push forward
- Difficulty cleaning and maintaining the area, leading to gum disease
- Pain and pressure as the tooth attempts to erupt against bone or another tooth
