Wisdom tooth extraction is a surgical procedure performed when the third molars (wisdom teeth) located at the very back of the mouth fail to find adequate space in the jaw or pose a risk of damaging other teeth. Wisdom teeth typically emerge between the ages of 17 and 30, and in some cases, they remain impacted, meaning they do not fully erupt. In such cases, dentists or oral surgeons may recommend extraction.

How is Wisdom Tooth Extraction Performed?

Normal Wisdom Tooth Extraction:

For fully erupted wisdom teeth, the extraction process is similar to a standard tooth extraction. The area is numbed with local anesthesia, and the dentist uses special tools to remove the tooth. This procedure is usually quick and straightforward.

Impacted Wisdom Tooth Extraction:

If the tooth has not fully erupted or is impacted under the gum, the extraction can be more complex. The gum is opened, and the bone covering the tooth is removed. The tooth may need to be divided into sections to facilitate removal. Afterward, the area is stitched closed.

When Should Wisdom Teeth Be Removed?

Wisdom teeth extraction may be necessary in the following situations:

• Severe decay or significant material loss in the tooth.
• Trauma or fracture to the tooth.
• The tooth does not contribute to chewing function.
• The tooth causes infection, abscess, cyst, or tumor formation.
• Misalignment or potential damage to other teeth.
• Interference with orthodontic treatment.

Duration of Wisdom Tooth Extraction

• Normal Wisdom Tooth Extraction: Typically takes about 20-30 minutes.
• Impacted Wisdom Tooth Extraction: Can take 45 minutes or longer, depending on the position and depth of the tooth under the gum.

Post-Extraction Care for Wisdom Teeth

After the extraction, consider the following:

• Avoid hard or hot foods for the first 24 hours; opt for soft foods.
• Refrain from rinsing, brushing, or spitting on the first day.
• Use pain relievers as recommended by your doctor to manage discomfort.
• Apply ice packs intermittently to reduce swelling.
• Avoid smoking and using straws for a few days post-surgery.
• Maintain regular oral hygiene but be gentle around the wound.

Side Effects of Wisdom Tooth Extraction

Like any surgical procedure, wisdom tooth extraction may result in some side effects:

• Swelling and mild pain at the extraction site.
• Temporary jaw stiffness.
• Bleeding or risk of infection in the extraction area.

These side effects typically subside quickly, and severe complications are rare.

Why Are Wisdom Teeth Removed?

• Pain and Discomfort: Impacted or improperly positioned wisdom teeth can cause severe pain and pressure.
• Food and Bacteria Accumulation: Partially erupted or impacted teeth can trap food and bacteria, leading to infections.
• Damage to Surrounding Teeth: Misaligned wisdom teeth can push against neighboring teeth, causing damage.
• Orthodontic Interference: Improperly positioned wisdom teeth can disrupt orthodontic treatments and alignment.

Pre-Extraction Preparation

• A detailed X-ray will be taken by the dentist or oral surgeon to evaluate the tooth's position and the difficulty of the extraction.
• Anesthesia options, including local anesthesia, sedation, or general anesthesia, may be discussed.

Complications of Wisdom Tooth Extraction

• Dry Socket: If the blood clot dislodges from the extraction site, the bone may be exposed, causing pain.
• Sinus Problems: Upper wisdom teeth close to the sinus cavity may lead to complications.
• Nerve Damage: Although rare, lower wisdom teeth extractions carry a risk of nerve injury, which can cause temporary or permanent numbness.

When to Contact a Dentist After Extraction

• Persistent or heavy bleeding.
• Severe and unrelenting pain.
• Signs of infection, such as fever or pus discharge.
• Swelling in the jaw, face, or throat.

Frequently Asked Questions About Wisdom Teeth

What happens when wisdom teeth erupt?

Wisdom teeth can cause pain, swelling, and gum sensitivity, especially if there is not enough space in the jaw. They may also increase the risk of inflammation and infection.

What happens if wisdom teeth are not removed?

Untreated wisdom teeth can crowd other teeth, causing misalignment and jaw pain. They may also lead to serious oral health issues such as infections, abscesses, and cysts.

Where does wisdom tooth pain radiate?

Wisdom tooth pain often spreads to the jaw and ear. It can also cause discomfort in the head, neck, and other teeth.

Is wisdom tooth extraction difficult?

The difficulty depends on the tooth's position and whether it is impacted. Impacted teeth require more complex surgical intervention, but local anesthesia ensures a pain-free procedure.

Can non-painful wisdom teeth be removed?

Yes, wisdom teeth that are not causing pain may still be removed proactively to prevent future complications. Dentists often recommend this to avoid potential issues.

How long does wisdom tooth extraction take?

The duration varies. A normal extraction takes about 20-30 minutes, while impacted teeth may take 45 minutes or longer.

When can you eat after wisdom tooth extraction?

Soft foods can typically be consumed about 2 hours after the extraction, once the anesthesia wears off. Avoid hard and hot foods for the first 24 hours.

Can you drink water after wisdom tooth extraction?

Yes, you can drink water after the procedure. However, avoid very hot or cold water and refrain from using a straw for the first 24 hours to prevent dislodging the blood clot (dry socket risk). Non-alcoholic and non-carbonated beverages are also safe.
