Wisdom Teeth Extraction: Understanding the Benefits and When It’s Necessary

Keanu Oliva • May 27, 2024

Wisdom teeth, also known as third molars, are the last set of teeth to erupt in the mouth, typically between the ages of 17 and 25. However, wisdom teeth don’t always erupt smoothly. They can become impacted, meaning they’re trapped beneath the gum line or bone due to lack of space. This can lead to a variety of problems, making wisdom teeth extraction a common dental procedure.


While some people might question the necessity of wisdom teeth extraction, there are several significant benefits to consider:

Preventing Pain and Infection:

Impacted wisdom teeth can cause a range of problems, including:


  • Pain: Pressure from erupting wisdom teeth can cause significant pain and discomfort in the jaw and surrounding areas.
  • Infection: Impacted wisdom teeth are more prone to infection, leading to swelling, redness, and tenderness in the gums.
  • Damage to Nearby Teeth: Impacted wisdom teeth can push against other teeth, causing misalignment and potential damage.
  • Gum Disease: Impacted wisdom teeth can make it difficult to properly clean the back of your mouth, increasing the risk of gum disease.

Preserving Jawbone Health:

Sometimes, wisdom teeth can erupt at an angle and damage the jawbone or nearby nerves. Early wisdom teeth extraction can prevent this potential damage and ensure proper jaw development.

Creating Space for Orthodontics:

If you’re considering orthodontic treatment (braces or aligners) to correct crowded teeth, wisdom teeth extraction might be necessary to create adequate space for proper alignment.

Reducing Risk of Cysts and Tumors:

In rare cases, impacted wisdom teeth can lead to the formation of cysts or tumors in the jawbone. Early extraction can minimize this risk.

Improved Oral Hygiene:

Wisdom teeth can be difficult to clean effectively, especially when impacted. Removing them can make brushing and flossing easier, improving overall oral hygiene.

Simplifying Future Dental Work:

If wisdom teeth cause problems later in life, extracting them at a younger age can be easier and less risky than waiting until complications arise.

Who Needs Wisdom Teeth Extraction?

Not everyone requires wisdom teeth extraction. However, it’s crucial to have your wisdom teeth evaluated by a dentist or oral surgeon to determine if extraction is necessary. Here are some factors that might influence the decision:


  • Impaction: If your wisdom teeth are impacted, extraction is often recommended to prevent potential complications.
  • Angulation: Wisdom teeth that erupt at an angle and crowd other teeth might need to be removed.
  • Lack of Space: If your jaw doesn’t have enough space to accommodate erupting wisdom teeth comfortably, extraction might be necessary.
  • Oral Health: Overall oral health plays a role. Individuals with pre-existing gum disease might benefit from wisdom teeth extraction to minimize future complications.

What to Expect During Wisdom Teeth Extraction

Wisdom teeth extraction is typically an outpatient procedure performed with local anesthesia or sedation. The specific procedure varies depending on the position of the wisdom tooth and its level of impaction. Here’s a general overview:


  • Consultation and X-rays: You’ll first have a consultation with your dentist or oral surgeon to discuss the procedure and any potential risks. X-rays will be taken to assess the position of your wisdom teeth.
  • Anesthesia: Depending on the complexity of the extraction, local anesthesia or sedation might be used to numb the area and ensure your comfort.
  • Extraction: The dentist or oral surgeon will carefully remove the wisdom tooth using specialized instruments.
  • Stitches and Recovery: Stitches might be used to close the extraction site, and you’ll receive specific instructions for post-operative care, including pain management and proper hygiene practices.

Benefits Outweigh Risks

While wisdom teeth extraction involves some recovery time and potential discomfort, the long-term benefits outweigh the risks for many individuals. It can alleviate pain, prevent future complications, and contribute to good oral health. Wisdom teeth extraction should be a collaborative decision between you and your dentist or oral surgeon. They will consider your individual situation and ensure you understand the procedure, risks, and benefits before moving forward.
