Wisdom tooth extraction is one of the most common oral surgeries performed by dentists and oral surgeons. While the procedure is generally safe and effective, like any surgery, it comes with potential risks and complications. If you or someone you know is considering having their wisdom teeth removed, it’s important to understand what to expect and how to minimize the risks involved.

1. Pain and Swelling

Pain and swelling are the most common side effects after wisdom tooth removal. The intensity varies from person to person, but most patients experience discomfort for a few days to a week. Swelling in the cheeks and jaw is also typical, especially if the teeth were impacted. Applying ice packs and taking prescribed pain medication can help manage these symptoms effectively.

2. Dry Socket (Alveolar Osteitis)

A dry socket occurs when the blood clot that forms at the extraction site gets dislodged or dissolves too soon, exposing the underlying bone and nerves. This can lead to severe pain, bad breath, and delayed healing. Dry sockets are more common in lower wisdom teeth extractions and in patients who smoke, drink through a straw, or don’t follow post-operative care instructions.

How to Reduce the Risk:

• Avoid smoking and drinking alcohol for at least 72 hours post-surgery. These activities can interfere with the formation of the blood clot at the extraction site. If the clot becomes dislodged or dissolves too soon, it may expose the underlying bone and nerves, leading to dry socket—a painful condition that delays healing.
• Don’t use a straw or spit forcefully, as this can dislodge the clot.
• Follow your dentist’s aftercare instructions carefully.

3. Infection

Although rare, infection can occur at the surgical site due to bacteria entering the open wound. Symptoms of infection include increasing pain, swelling, redness, fever, and pus drainage from the extraction site.

How to Reduce the Risk:

• Take prescribed antibiotics if recommended by your dentist.
• Maintain good oral hygiene but avoid disturbing the extraction site.
• Rinse with warm salt water as instructed.

4. Nerve Damage

The lower wisdom teeth are located close to major nerves in the jaw. In rare cases, these nerves may become irritated or damaged during extraction, leading to temporary or, in very rare cases, permanent numbness or tingling in the lips, tongue, or chin.

How to Reduce the Risk:

• Choosing an experienced oral surgeon or dentist minimizes this risk.
• Pre-surgical X-rays or 3D imaging can help assess nerve proximity before surgery.

5. Jaw Stiffness and Difficulty Opening the Mouth

Some patients experience trismus, or difficulty opening the mouth, after wisdom tooth removal. This happens when the muscles around the jaw become inflamed due to the procedure.

How to Reduce the Risk:

• Apply warm compresses after the first 24 hours to relax the muscles.
• Perform gentle jaw exercises as recommended by your dentist.

6. Sinus Complications (For Upper Wisdom Teeth)

Since upper wisdom teeth are close to the sinus cavities, their removal can sometimes cause a temporary opening between the mouth and sinus. Symptoms include nasal congestion, sinus pain, or a runny nose after surgery.

How to Reduce the Risk:

• Avoid blowing your nose forcefully for at least a week post-surgery.
• Follow post-operative care instructions carefully.

7. Delayed Healing in Smokers

Smoking significantly delays healing and increases the risk of complications like dry socket, infection, and excessive bleeding. Nicotine restricts blood flow to the surgical site, making it harder for the body to recover.

How to Reduce the Risk:

• Avoid smoking for at least one week post-surgery, ideally longer.
• Consider cutting down on smoking before the procedure to improve healing.

8. Excessive Bleeding

Mild bleeding is normal after surgery, but excessive bleeding that doesn’t slow down within a few hours can be concerning.

How to Reduce the Risk:

• Bite down on gauze as instructed to help clot formation.
• Avoid heavy physical activity for at least 48 hours.
• Keep your head elevated while sleeping.

When to Call Your Dentist

While most wisdom tooth extractions heal without major issues, you should contact your dentist if you experience:

• Severe or worsening pain after 3-4 days
• Excessive bleeding that won’t stop
• Signs of infection (fever, pus, swelling)
• Numbness that persists beyond a few days
• Difficulty breathing or swallowing

Final Thoughts

Wisdom tooth extraction is a routine procedure, but being aware of the potential risks can help you prepare for a smoother recovery. By choosing an experienced dentist, following post-operative care instructions, and making lifestyle adjustments, you can minimize complications and heal quickly.
