Can Impacted Wisdom Teeth Increase Oral Cancer Risk?
When you hear about impacted wisdom teeth, you probably think of pain, swelling, or maybe the hassle of surgery. But what about the potential risk of oral cancer? It’s a concern that many might not immediately associate with these troublesome teeth.
Understanding this connection is vital for anyone dealing with impacted wisdom teeth, as it can help you take informed steps to protect your oral health. In this article, we’ll delve into the facts, separating myths from reality, and provide you with clear, actionable information.
What Are Impacted Wisdom Teeth?
Did you know Most people (around 65%) don't even have a full set (4) of wisdom teeth! In fact, some people are born with none at all.
Impacted wisdom teeth are the third set of molars at the back of your mouth that don’t have enough room to emerge or develop normally. These teeth typically appear between the ages of 17 and 25. When they don’t fully erupt, they are considered “impacted.” This can happen due to several reasons:
- Lack of Space: The jaw may not have enough room to accommodate these additional teeth.
- Growth Angle: They might grow at an angle, pressing against other teeth.
- Encased in Bone or Tissue: Sometimes, the teeth remain trapped in the jawbone or gums.
Common issues associated with impacted wisdom teeth include pain, swelling, infections, and damage to adjacent teeth. When left untreated, they can lead to more severe complications, such as cysts or tumors, which can increase the risk of developing oral cancer.
How Can Impacted Wisdom Teeth Lead to Oral Cancer?
Understanding how impacted wisdom teeth might increase the risk of oral cancer involves looking at the complications they can cause. Impacted wisdom teeth can create an environment where harmful changes in your mouth are more likely. Here are some ways this can happen:
- Chronic Inflammation: Constant irritation and infection around impacted teeth can lead to chronic inflammation. Long-term inflammation is a known risk factor for various types of cancer, including oral cancer.
- Cysts and Tumors: Impacted wisdom teeth can cause cysts to form in the gums. These cysts can damage nearby bone and teeth and may sometimes turn into tumors. While most of these tumors are benign, there is a risk they could become malignant over time.
- Bacterial Infections: Impacted teeth can harbor bacteria, leading to persistent infections. Some studies suggest that long-term infections can contribute to the development of cancerous cells in the oral cavity.
Symptoms of Oral Cancer Linked to Impacted Wisdom Teeth
If you experience any of these symptoms, it’s important to seek medical advice promptly. Early diagnosis and treatment are critical in managing oral cancer effectively:
- Persistent Mouth Sores: Sores that do not heal within two weeks can be a warning sign.
- Unexplained Bleeding: Any unexplained bleeding in your mouth should be checked by a dentist or doctor.
- Lumps or Thickening: Feeling a lump or thickening in your cheek, gums, or other areas inside your mouth can indicate abnormal tissue growth.
- Difficulty Chewing or Swallowing: Persistent difficulty in chewing or swallowing might be linked to underlying issues.
- Pain or Numbness: Persistent pain or a feeling of numbness in your mouth or jaw can be symptoms of oral cancer.
What Research Says
While the idea of impacted wisdom teeth leading to oral cancer can be alarming, it’s important to rely on scientific evidence to understand this risk. Currently, there is limited direct evidence linking impacted wisdom teeth specifically to oral cancer.
However, the complications arising from impacted teeth, such as chronic inflammation, cysts, and infections, are well-documented risk factors for oral cancer. Here are some findings from recent studies:
- Inflammation and Cancer: Chronic inflammation caused by persistent infections around impacted wisdom teeth can increase the risk of cellular changes that may lead to cancer. Research from MIT has shown that chronic inflammation can create DNA mutations that are associated with cancer development (MIT News).
- Cyst Formation: Dental cysts can cause tissue changes in the mouth, potentially leading to pre-cancerous conditions if left untreated. The National Cancer Institute (NCI) notes that chronic inflammation and other conditions can significantly increase cancer risk (Comprehensive Cancer Information).
- Bacterial Infections: Long-standing bacterial infections from impacted teeth may contribute to an environment conducive to cancer development. Persistent infections and inflammation are highlighted as risk factors for cancer by multiple studies (Comprehensive Cancer Information).
In summary, while there’s no definitive link established between impacted wisdom teeth and oral cancer, the conditions created by these teeth can increase the overall risk factors associated with cancer.
How Removing Wisdom Teeth Can Reduce the Risk of Oral Cancer
Removing impacted wisdom teeth can be a proactive step in reducing potential risks associated with these problematic teeth, including the risk of developing oral cancer. Here are some key points to consider:
- Eliminating Chronic Inflammation: Removing impacted teeth can eliminate the source of chronic inflammation and infection, thereby reducing the risk of these conditions contributing to cancer.
- Preventing Cysts and Tumors: By removing the impacted teeth, you can prevent the formation of cysts and tumors, which, although usually benign, have the potential to become malignant.
- Improving Oral Hygiene: Post-removal, maintaining good oral hygiene becomes easier, reducing the likelihood of bacterial infections that could contribute to cancer risks.
However, it’s essential to weigh the benefits and risks of surgery. Consultation with a dental professional can provide personalized advice based on your specific situation.
Risk factors to Consider
Certain factors can increase the risk of oral cancer, especially in individuals with impacted wisdom teeth. These risk factors include:
- Tobacco Use: Smoking or using smokeless tobacco products significantly increases the risk of oral cancer.
- Heavy Alcohol Consumption: Regular heavy drinking is a known risk factor for oral cancer.
- HPV Infection: Human papillomavirus (HPV), particularly HPV-16, is linked to an increased risk of oropharyngeal cancers.
- Poor Oral Hygiene: Inadequate oral care can lead to persistent infections and chronic inflammation, contributing to cancer risk.
- Family History: A family history of cancer can also increase your susceptibility.
By being aware of these risk factors, you can take steps to mitigate them and discuss any concerns with your dentist for a tailored preventive approach.
How Common is Oral Cancer?
While having impacted wisdom teeth can contribute to conditions that may increase cancer risk, it is not a definitive cause of oral cancer. Here’s a comparison:
| Condition | Prevalence |
|---|---|
| Impacted Wisdom Teeth | Common (affects up to 90% of people) |
| Oral Cancer | Less common (affects 11 in 100,000 people) |
| Oral Cancer in Those with Impacted Wisdom Teeth | Not significantly higher without additional risk factors |
This table shows that while impacted wisdom teeth are common, the actual occurrence of oral cancer remains relatively low. Regular monitoring and proactive dental care are essential to managing any potential risks.

Preventative Measures
Taking proactive steps can significantly reduce the risk of oral cancer associated with impacted wisdom teeth. Here are some effective strategies:
- Regular Dental Check-ups: Schedule regular visits to your dentist to monitor your oral health.
- Good Oral Hygiene: Brush and floss daily to prevent infections.
- Avoid Tobacco and Excessive Alcohol: Both significantly increase the risk of oral cancer.
- Early Removal of Problematic Wisdom Teeth: Consult with your dentist about removing impacted teeth if necessary.
- Healthy Diet: Eat a balanced diet rich in fruits and vegetables to support overall oral health.
Conclusion
Impacted wisdom teeth can pose various risks, including the potential for oral cancer. While the direct link to oral cancer is not definitively established, complications like chronic inflammation, cysts, and infections can increase cancer risk factors.
Protect your oral health by staying proactive: schedule regular dental check-ups, maintain good oral hygiene, and avoid tobacco and excessive alcohol. If you have concerns about your impacted wisdom teeth, seek professional advice.
