Removing wisdom teeth, also known as third molars, is a common dental procedure that many people undergo during their late teens or early twenties. The decision to remove these teeth often stems from a variety of reasons, including potential for oral health issues, discomfort, and space constraints. This article delves into the reasons behind wisdom teeth extraction, the potential benefits and risks, and the impact it can have on oral health and overall well-being.
Understanding Wisdom Teeth
Wisdom teeth are the third set of molars located at the back of the mouth, one on each side of the upper and lower jaws.
They typically emerge between the ages of 17 and 25, a period often referred to as the “age of wisdom,” which is where the name originates. Evolutionarily, these teeth were necessary for our ancestors, who had larger jaws and a diet that required more chewing power. However, as human diets have changed and our jaws have become smaller, wisdom teeth have become less functional and more prone to complications.

Reasons for Removing Wisdom Teeth
Several factors can lead to the decision to remove wisdom teeth. The most common reasons include:
Impaction: Wisdom teeth often become impacted, meaning they do not fully emerge from the gums or emerge at an angle.
This can cause pain, swelling, and infection. Impaction can also lead to the formation of cysts or tumors in the jawbone.
Crowding: If there is insufficient space in the jaw for wisdom teeth to emerge properly, they can cause crowding of adjacent teeth. This can disrupt the alignment of the entire dental arch and undo orthodontic work.
Infection and Decay: Partially erupted wisdom teeth can be difficult to clean properly, leading to a higher risk of decay and gum disease. The location of these teeth makes them hard to reach with a toothbrush or floss.
Gum Disease: The area around wisdom teeth can be prone to gum disease due to difficulty in maintaining good oral hygiene. This can lead to inflammation, infection, and other periodontal issues.
Pain and Discomfort: Wisdom teeth can cause significant discomfort or pain, especially if they are growing in at an awkward angle or are causing pressure on other teeth.
The Procedure for Wisdom Teeth Removal
Wisdom teeth removal is typically performed by an oral surgeon or a dentist with specialized training. The procedure can vary depending on the complexity of the case and the positioning of the teeth. Here is a general overview of what to expect:
Preoperative Evaluation: Before the procedure, a thorough evaluation is conducted, including X-rays to assess the position and condition of the wisdom teeth and surrounding structures.
Anesthesia: Wisdom teeth removal is usually performed under local anesthesia to numb the area, although sedation or general anesthesia may be used for more complex cases or if the patient prefers.
Extraction: The procedure involves making an incision in the gum tissue to access the wisdom teeth. In some cases, the teeth may need to be sectioned into smaller pieces to facilitate their removal. The surgeon then cleans the extraction site and may place stitches if necessary.
Postoperative Care: After the removal, patients are given instructions for care, including pain management, oral hygiene, and dietary restrictions. Recovery times vary, but most people can return to normal activities within a few days to a week.
What Does Removing Wisdom Teeth Do?
Removing wisdom teeth can provide several benefits, especially when performed proactively before complications arise.
Some of these benefits include:
Prevention of Oral Health Issues: By removing wisdom teeth that are prone to problems, such as impaction or decay, you can prevent future oral health issues and avoid more complicated procedures.
Improved Oral Hygiene: Extraction can make it easier to maintain good oral hygiene by eliminating hard-to-reach areas and reducing the risk of gum disease.
Reduced Risk of Infection: Wisdom teeth that are partially erupted or impacted are at higher risk for infections, such as pericoronitis. Removing them can reduce the likelihood of these infections.
Prevention of Orthodontic Problems: For individuals who have had orthodontic treatment, removing wisdom teeth can help maintain the results and prevent misalignment or crowding of teeth.
Risks And Complications
While wisdom teeth removal is generally safe, there are potential risks and complications associated with the procedure.
These can include:
Infection: There is a risk of infection at the extraction site, which can lead to swelling, pain, and prolonged healing. Proper postoperative care and hygiene can help minimize this risk.
Dry Socket: A condition known as dry socket can occur if the blood clot at the extraction site becomes dislodged or dissolves too early, exposing the bone and nerves. This can cause severe pain and delay healing.
Nerve Injury: In rare cases, the removal of wisdom teeth can lead to injury of the nerves that run near the extraction site.
This can result in temporary or permanent numbness or tingling in the lips, tongue, or chin.
Bleeding: Some bleeding is normal after the procedure, but excessive bleeding can occur in rare cases. Following the dentist’s instructions can help control bleeding and promote proper clot formation.
Postoperative Care And Recovery
Following the removal of wisdom teeth, proper postoperative care is crucial for a smooth recovery. Key aspects of postoperative care include:
Pain Management: Over-the-counter pain medications or prescribed pain relievers can help manage discomfort. Applying ice packs to the outside of the face can also reduce swelling.
Oral Hygiene: Maintaining oral hygiene is essential to prevent infection. Gently brushing the teeth and using a prescribed mouth rinse can help keep the mouth clean. Avoiding brushing directly on the extraction site until it has healed is important.
Dietary Restrictions: For the first few days, stick to soft foods and avoid hot, spicy, or hard foods that could irritate the extraction site. Drinking plenty of fluids is also important.
Avoiding Strenuous Activities: Refrain from engaging in strenuous physical activities or sucking motions, such as smoking or using a straw, which can dislodge the blood clot and lead to complications.
Long-Term Effects
In most cases, removing wisdom teeth can have positive long-term effects on oral health. By addressing potential problems early, you can avoid more serious issues in the future. Additionally, the removal of wisdom teeth can contribute to better alignment and health of the remaining teeth.
When to Consider Removal
Not everyone needs to have their wisdom teeth removed. Your dentist or oral surgeon will evaluate your specific case and recommend removal if it is necessary. It is often recommended to have wisdom teeth removed proactively if they are likely to cause problems, rather than waiting for issues to arise.
Conclusion
Removing wisdom teeth is a common dental procedure that can prevent a range of oral health issues, including impaction, decay, and gum disease. While the procedure involves some risks, the benefits of removing problematic wisdom teeth often outweigh these risks. Proper care and follow-up with your dentist are essential to ensure a smooth recovery and maintain optimal oral health. If you have concerns about your wisdom teeth or are experiencing discomfort, consult with your dentist to determine the best course of action for your individual needs.
