Wisdom Tooth Removal: When Impacted Teeth Need Surgery

Wisdom teeth do not always need to be removed. Some erupt normally, remain healthy, and can be cleaned properly. Others become trapped under the gum or bone, partly erupt, or push against neighbouring teeth. When that happens, they can cause pain, swelling, repeated infections, tooth damage, or crowding.

My role is to assess the tooth carefully, explain what I see on your imaging, and help you understand whether monitoring or removal is the better option.

What is an impacted tooth?

An impacted tooth is one that cannot erupt into its normal position. Wisdom teeth are the most common example because they are the last adult teeth to develop and often do not have enough room in the jaw.

A wisdom tooth may be:

• Fully impacted under gum tissue or bone
• Partially erupted, leaving a pocket where food and bacteria collect
• Tilted toward the tooth in front of it
• Growing in a direction that may affect nearby structures

Other teeth, especially upper canine teeth, can also become impacted and may require surgical treatment or coordination with an orthodontist.

When is wisdom tooth removal recommended?

I may recommend removal when a wisdom tooth is associated with:

• Recurrent pain, swelling, or gum infection
• Difficulty opening the mouth or chewing comfortably
• Cavities in the wisdom tooth or the adjacent molar
• Damage to the neighbouring tooth
• Gum or bone loss around nearby teeth
• A cyst or other abnormal change around the tooth
• An impacted position that creates a significant future risk

Not every impacted wisdom tooth causes symptoms right away. A thorough examination and X-ray assessment help us make a decision based on your specific risk—not simply on the fact that you have wisdom teeth.

What happens at the consultation?

At your appointment, I review your health history, medications, symptoms, and dental imaging. I look at the position of the tooth, the roots, and nearby nerves or sinus spaces.

This is particularly important for lower wisdom teeth, where the roots may be close to the nerve that provides feeling to the lip and chin. If there is a concern, additional three-dimensional imaging may be useful to plan the safest approach.

You should leave the consultation understanding:

• Why removal is or is not recommended
• Whether the tooth is simple or more complex to remove
• Your anaesthesia and sedation options
• Expected recovery time
• Possible risks and how we reduce them

What is recovery like after wisdom tooth surgery?

Most patients need a few quieter days after surgery. Swelling is usually most noticeable during the first two to three days and then gradually improves. Mild bleeding or oozing on the first day is common.

I generally advise patients to plan for:

• Soft foods and plenty of fluids for the first few days
• Rest on the day of surgery
• Avoiding smoking, vaping, alcohol, and drinking through straws during early healing
• Taking prescribed or recommended medication as directed
• Gentle oral hygiene around the surgical area

A dry socket, infection, prolonged bleeding, or worsening pain are not things to ignore. Contact the office promptly if you have concerns after surgery.

Do all wisdom teeth need to be removed?

No. If a wisdom tooth is healthy, fully erupted, easy to clean, and not harming nearby teeth, monitoring may be appropriate. The decision should be based on your clinical examination, imaging, symptoms, and long-term oral health—not a one-size-fits-all rule.

When to seek urgent care

Please seek timely dental or medical care if you have facial swelling, fever, difficulty swallowing, difficulty breathing, severe pain that is not controlled by medication, or signs of a spreading infection.
