Wisdom teeth, also known as third molars, are the last set of teeth to develop in the mouth. They typically emerge between the ages of 17 and 25, a time when most people have already developed a full set of permanent teeth. However, wisdom teeth often cause problems and may need to be extracted. This article aims to answer common questions about tooth extractions for wisdom teeth, providing valuable insights based on research and expert opinions.

What are wisdom teeth?

Wisdom teeth are the third molars located at the back of the mouth. Most people have four wisdom teeth, one in each corner of the mouth. These teeth are called “wisdom teeth” because they usually emerge during the late teenage years or early twenties, a time when a person is considered to be gaining wisdom.

Wisdom teeth are remnants of our evolutionary past when our ancestors had larger jaws and needed these extra molars to chew tough and coarse foods. However, as our jaws have become smaller over time, there is often insufficient space for wisdom teeth to fully emerge and function properly.

Why do wisdom teeth need to be extracted?

Wisdom teeth often cause problems due to their late eruption and lack of space in the mouth. Here are some common reasons why wisdom teeth may need to be extracted:

  • Impacted wisdom teeth: When there is not enough space for the wisdom teeth to fully emerge, they can become impacted. This means that they are trapped beneath the gum line or partially erupted, causing pain, swelling, and an increased risk of infection.
  • Crowding: Wisdom teeth can push against the existing teeth, causing crowding and misalignment. This can lead to bite problems and the need for orthodontic treatment.
  • Tooth 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, which may require extraction.
  • Cysts and tumors: In some cases, wisdom teeth can develop cysts or tumors. These growths can cause damage to the surrounding teeth, jawbone, and nerves, necessitating extraction.

When should wisdom teeth be extracted?

The timing of wisdom tooth extraction depends on various factors, including the individual’s age, the position of the teeth, and the presence of any symptoms or complications. In general, it is recommended to have wisdom teeth evaluated by a dentist or oral surgeon in the late teenage years or early twenties, even if there are no apparent problems.

Early evaluation allows for the identification of potential issues before they worsen. It also provides an opportunity to discuss the best course of action with the dental professional. In some cases, it may be advisable to extract the wisdom teeth preventively, even if they are not causing immediate problems.

What is the process of wisdom tooth extraction?

Wisdom tooth extraction is a common dental procedure that is typically performed by a dentist or oral surgeon. The process involves several steps:

  1. Evaluation: The dentist or oral surgeon will examine the wisdom teeth and take X-rays to assess their position and determine the best approach for extraction.
  2. Anesthesia: Before the extraction, the patient will be given a local anesthetic to numb the area around the tooth. In some cases, general anesthesia may be used, especially if multiple teeth are being extracted or if the procedure is complex.
  3. Extraction: The dentist or oral surgeon will make an incision in the gum tissue to access the tooth. If the tooth is impacted, they may need to remove some bone to fully extract it. Once the tooth is removed, the area will be cleaned and stitched if necessary.
  4. Recovery: After the extraction, the patient 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 promote proper healing.

What is the recovery process like after wisdom tooth extraction?

The recovery process after wisdom tooth extraction can vary from person to person, but here are some general guidelines:

  • Pain and swelling: It is normal to experience some pain and swelling after the extraction. This can be managed with over-the-counter pain relievers and by applying ice packs to the affected area.
  • Bleeding: There may be some bleeding from the extraction site, which can be controlled by biting down on a gauze pad or tea bag. If the bleeding persists or becomes excessive, it is important to contact the dentist or oral surgeon.
  • Diet: It is recommended to stick to a soft or liquid diet for the first few days after the extraction. Avoiding hard, chewy, or spicy foods can help prevent irritation or damage to the extraction site.
  • Oral hygiene: It is important to maintain good oral hygiene after wisdom tooth extraction. However, it is necessary to avoid brushing the extraction site for the first 24 hours. After that, gentle brushing can be resumed, taking care to avoid the extraction site.
  • Follow-up appointments: The dentist or oral surgeon will schedule follow-up appointments to monitor the healing process and remove any stitches if necessary.

It is essential to follow all post-operative instructions provided by the dental professional to ensure proper healing and minimize the risk of complications.


Wisdom tooth extraction is a common dental procedure performed to address problems associated with the eruption of third molars. Impacted wisdom teeth, crowding, tooth decay, gum disease, and the development of cysts or tumors are some of the reasons why extraction may be necessary. The timing of extraction depends on various factors, and early evaluation is recommended to identify potential issues. The extraction process involves evaluation, anesthesia, extraction, and recovery. The recovery period may involve pain, swelling, bleeding, dietary restrictions, and specific oral hygiene instructions. Following these guidelines and attending follow-up appointments is crucial for proper healing. If you have concerns about your wisdom teeth, it is best to consult with a dental professional who can provide personalized advice and guidance.
