Oral surgery is a specialized branch of dentistry that focuses on diagnosing and treating conditions related to the mouth, jaw, and face. One common procedure performed in oral surgery is wisdom teeth extraction. Wisdom teeth, also known as third molars, are the last set of teeth to emerge in the mouth. Due to various reasons, these teeth often need to be removed. In this article, we will explore frequently asked questions about wisdom teeth extraction and other oral surgery procedures.

What are wisdom teeth?

Wisdom teeth are the third molars that typically emerge between the ages of 17 and 25. Most adults have four wisdom teeth, one in each corner of the mouth. However, some individuals may have fewer or even none at all. These teeth are remnants of our evolutionary past when our ancestors needed the extra chewing power to consume a rougher diet.

Wisdom teeth can cause various problems due to their late eruption and limited space in the mouth. They may grow at odd angles, become impacted, or fail to fully emerge from the gums. These issues can lead to pain, infection, and damage to adjacent teeth.

Why do wisdom teeth need to be extracted?

Wisdom teeth often need to be extracted due to the following reasons:

  • Impaction: When a wisdom tooth does not have enough space to fully emerge, it becomes impacted. Impacted wisdom teeth can cause pain, swelling, and infection. They can also push against adjacent teeth, leading to misalignment or damage.
  • Crowding: The eruption of wisdom teeth can cause overcrowding in the mouth, especially if there is not enough space for them to grow properly. This can lead to misalignment of the other teeth and may require orthodontic treatment.
  • Decay and gum disease: Wisdom teeth are located at the back of the mouth, making them difficult to clean properly. This can increase the risk of tooth decay and gum disease. Removing the wisdom teeth can help prevent these oral health issues.
  • Cysts and tumors: In rare cases, wisdom teeth can develop cysts or tumors. These growths can cause damage to the jawbone and surrounding structures. Removing the affected wisdom teeth is necessary to prevent further complications.

What is the process of wisdom teeth extraction?

The process of wisdom teeth extraction involves several steps:

  1. Consultation: The first step is to consult with an oral surgeon. During the consultation, the surgeon will examine your mouth, take X-rays, and discuss the best course of action.
  2. Anesthesia: Before the extraction, the surgeon will administer anesthesia to ensure you are comfortable and pain-free during the procedure. The type of anesthesia used can vary depending on the complexity of the extraction and your personal preference.
  3. Extraction: The surgeon will then proceed with the extraction. If the wisdom tooth has fully emerged, it can be removed like any other tooth. However, if the tooth is impacted or partially erupted, the surgeon may need to make an incision in the gum and remove the tooth in sections.
  4. Stitches: After the extraction, the surgeon may place stitches to promote proper healing of the surgical site. These stitches are typically dissolvable and do not need to be removed.
  5. Recovery: Following the procedure, you will be given instructions on how to care for the extraction site and manage any discomfort or swelling. It is important to follow these instructions to ensure a smooth recovery.

What is the recovery process like after wisdom teeth extraction?

The recovery process after wisdom teeth extraction can vary from person to person. However, here are some general guidelines:

  • Pain and swelling: It is normal to experience some pain and swelling after the extraction. The surgeon may prescribe pain medication or recommend over-the-counter pain relievers to manage the discomfort. Applying an ice pack to the affected area can help reduce swelling.
  • Bleeding: It is common to experience some bleeding for the first 24 hours after the extraction. The surgeon will provide you with gauze pads to bite down on to control the bleeding. It is important to change the gauze pads as instructed.
  • Diet: For the first few days, it is recommended to stick to a soft or liquid diet to avoid putting pressure on the extraction site. Avoid hot and spicy foods, as they can irritate the area.
  • Oral hygiene: It is crucial to maintain good oral hygiene during the recovery period. However, you should avoid brushing the extraction site for the first 24 hours. After that, gently rinse your mouth with warm saltwater to keep the area clean.
  • Follow-up appointments: The surgeon will schedule follow-up appointments to monitor your healing progress. It is important to attend these appointments and inform the surgeon of any concerns or complications.

What are the risks and complications associated with wisdom teeth extraction?

While wisdom teeth extraction is a common and relatively safe procedure, there are some risks and complications to be aware of:

  • Dry socket: Dry socket is a condition that occurs when the blood clot that forms in the extraction site becomes dislodged or dissolves prematurely. This can cause severe pain and delay the healing process. To prevent dry socket, it is important to follow the post-operative instructions provided by the surgeon.
  • Infection: Infection is a potential risk after any surgical procedure, including wisdom teeth extraction. The surgeon will prescribe antibiotics if necessary and provide instructions on how to prevent infection.
  • Nerve damage: The roots of wisdom teeth are located near nerves that supply sensation to the lips, tongue, and chin. In rare cases, the extraction of wisdom teeth can cause temporary or permanent nerve damage, resulting in numbness or tingling in these areas.
  • Damage to adjacent teeth: During the extraction process, adjacent teeth may be accidentally damaged. This can include chips, fractures, or displacement of the neighboring teeth. However, such complications are rare and can usually be avoided with the expertise of an experienced oral surgeon.

It is important to discuss these risks and complications with your oral surgeon before undergoing wisdom teeth extraction. They will be able to assess your individual case and provide personalized advice.


Wisdom teeth extraction is a common oral surgery procedure that is often necessary to prevent pain, infection, and other complications. The process involves a consultation with an oral surgeon, administration of anesthesia, extraction of the wisdom teeth, and a recovery period. While there are risks and complications associated with the procedure, they are relatively rare and can be minimized with proper care and expertise. If you have concerns about your wisdom teeth or any other oral surgery procedure, it is best to consult with a qualified oral surgeon who can provide personalized advice and guidance.
