Can a Tooth Infection Cause Hair Loss?

Studies suggest that extreme hair loss can occur if a tooth infection is severe and left untreated for an extended period1. Hair loss caused by tooth infections typically occurs near the infected tooth, potentially affecting facial hair5. Tooth infections can cause systemic inflammation, which can affect the entire body and, in turn, contribute to hair loss3.

How Tooth Infections Contribute to Hair Loss

Tooth infections can lead to a range of complications, some of which may eventually result in hair loss. Some ways in which tooth infections can cause hair loss include:

  • Systemic Inflammation: Tooth infections can cause systemic inflammation, potentially affecting hair follicles and leading to hair loss3.
  • Alopecia Areata: In extreme cases, tooth infections could trigger an autoimmune response, leading to alopecia areata. This condition occurs when white blood cells mistakenly attack hair follicles, causing hair growth to stop6.

Treatment and Prevention of Hair Loss Due to Tooth Infections

If a tooth infection is caught in time, a dentist can treat the affected tooth, and the associated hair loss may reverse naturally5. To prevent tooth infections and potential hair loss, consider the following tips:

  • Maintain good oral hygiene by brushing and flossing daily
  • Visit your dentist for regular check-ups and cleanings
  • Seek immediate dental care if you experience symptoms of a tooth infection, such as severe pain, swelling, or fever8

Conclusion

While the connection between tooth infections and hair loss is not entirely definitive, there is evidence to suggest that untreated, severe tooth infections can contribute to hair loss in some cases1. Early detection and treatment of tooth infections are essential to minimize the risk of complications, including hair loss. Maintaining good oral hygiene and seeking timely dental care can help prevent tooth infections and any associated hair loss.
