Dental cavities linked to lower risk of head and neck cancer

From the JAMA Otolarynology - Head & Neck Surgery, a new study conducted by scientists at the University of Buffalo in New York is suggesting that people with MORE cavities are actually at LOWER risk of developing head and neck cancer.

How are dental caries/tooth decay formed?  Persistent bacteria that remain on teeth feed on the plaque left over from food debris; as a result the bacteria release lactic enzyme that demineralize and literally erodes the enamel, causing a cavity and sometimes necessitating the need for a filling.  

The study suggests that aside from the harmful effects of the bacteria in the mouth on the teeth, these bacteria are actually beneficial in the saliva and inside the mouth's mucosa, and may be a protective factor against head and neck cancer.

Now does this mean that one should actually stop brushing and flossing?  Probably not, but rather take this article in heart and realize that one's oral health and body work in concert. Twice a day brushing combined with daily flossing is recommended for optimal oral and systemic health.

If you have any questions or concerns regarding oral hygiene, be sure to ask your family dentist or hygienist.  Have a great one!
