tooth decay may cause acne
Hope this helps someone.
Recently got a clue (OK, maybe I'm slow) and realized the most likely cause of my cystic breakout last summer -- an abcessed tooth. I have a porcelain cap on a bottom molar that had been leaking and subsequently caused an infection in the tooth which grew a nasty abcess. The tooth needed a root canal (which I got). I think Plexion helped to clear the cysts since my skin was once again clear before the root canal. But had I not gotten the root canal, I probably would have had another unusual breakout.
Following is an article from a message board at usdental.net:
MY QUESTION IS THIS:
Can tooth decay contribute to acne?
Answered by Kim Loos, DDS
Q: I have a bad case of acne. After several medications were unsuccessful, my dermatologist suggested that I schedule a dental exam. He said cavities may fuel my acne infection. How can this be?
A: An abscessed or decayed tooth may contribute to acne. Dermatologists described a patient who had acne outbreaks that did not respond to traditional medications (Boyd et al. 1999). However, the acne disappeared after the patient had an abscessed tooth removed. This cycle of acne outbreak, tooth decay diagnosis, dental treatment and acne cure was repeated on several separate occasions.
Acne vulgaris triggers the immune system to produce antibodies against Propionibacterium acnes, the bacteria found in acne lesions. This bacteria is also commonly found in the mouth and throat. The authors concluded, "We believe that the presence of our patient's dental infections provoked a follicular inflammatory response resulting in his recalcitrant acne."
This limited anecdotal evidence does not prove that tooth decay contributes to stubborn cases of acne vulgaris. Most people with tooth decay do not have acne. Alternatively, most people with acne do not have tooth decay. However, if your acne does not improve with benzoyl peroxide, tetracycline, or other medications, perhaps it is time to visit your dentist!
