The Most Common Causes for Wisdom Tooth Extraction You Should Know

Wisdom teeth, also known as third molars, are the last set of teeth to emerge in the mouth, usually appearing between the ages of 17 and 25. While some people experience no issues with their wisdom teeth, others encounter a range of problems that necessitate extraction. At Smile Works, we prioritize your oral health and want to help you understand why wisdom tooth extraction might be necessary. Here are the most common causes for wisdom tooth extraction you should know.

Tooth Extraction

1. Impacted Teeth

One of the most frequent reasons for extracting wisdom teeth is impaction. An impacted tooth occurs when the tooth fails to emerge properly from the gum line due to a lack of space in the mouth. This can lead to pain, swelling, and even infection. Impacted wisdom teeth can be classified as:

  • Soft Tissue Impaction: The tooth partially erupts but remains covered by gum tissue.

  • Partial Bony Impaction: The tooth is partially emerged but part of the crown remains trapped in the jawbone.

  • Complete Bony Impaction: The tooth is entirely encased within the jawbone.

2. Crowding

As wisdom teeth attempt to emerge, they can push adjacent teeth out of alignment, causing crowding. This is especially problematic if you've previously undergone orthodontic treatment, as the pressure from wisdom teeth can undo years of corrective work. Extracting wisdom teeth can help maintain the alignment and spacing of your other teeth.

3. Tooth Decay

Wisdom teeth are located at the very back of the mouth, making them difficult to clean effectively. This can lead to an increased risk of tooth decay. If a wisdom tooth develops a cavity that is hard to treat due to its position, extraction may be the best solution to prevent further dental problems.

4. Gum Disease

Similar to tooth decay, the hard-to-reach position of wisdom teeth makes them more susceptible to gum disease. Bacteria and food particles can easily get trapped around partially erupted wisdom teeth, leading to inflammation, infection, and periodontal disease. In cases where gum disease affects the wisdom teeth, extraction is often recommended to protect overall oral health.

5. Cysts and Tumors

In rare cases, wisdom teeth can contribute to the development of cysts or tumors. A cyst is a fluid-filled sac that can form around an impacted tooth and potentially damage surrounding bone and tissue. If not addressed, cysts can lead to more serious complications and may require surgical removal of the affected tooth and surrounding tissues.

6. Pain and Discomfort

Persistent pain and discomfort are common indicators that wisdom teeth need to be removed. This pain can result from impaction, infection, or pressure on adjacent teeth. If you experience ongoing pain in the back of your mouth, it’s important to consult with a dental professional to determine whether extraction is necessary.

7. Repeated Infections

Pericoronitis is a condition characterized by repeated infections of the soft tissue around a partially erupted wisdom tooth. This condition can cause significant pain, swelling, and difficulty chewing. If pericoronitis occurs frequently, extracting the problematic wisdom tooth may be the most effective way to prevent future infections.


Wisdom tooth extraction is a common dental procedure aimed at preventing and addressing a variety of oral health issues. If you experience any symptoms related to your wisdom teeth, it’s crucial to consult with a dental professional.
