A new study has highlighted the hidden danger of neglecting regular brushing and flossing, which can lead to a severe type of head and neck cancer.

According to numerous previous studies, serious conditions such as head and neck cancer, as well as diabetes and high blood pressure, are more likely to develop in the presence of high levels of bacteria associated with gum disease. However, these studies have not always identified the specific type of oral bacteria responsible for head and neck cancer.

The study, conducted by researchers at New York University, confirmed that bacteria associated with gum disease increase the likelihood of developing squamous cell carcinoma of the head and neck by up to 50%.

Squamous cells are flat cells that line the mouth, nose, and throat, playing a key role in the spread of cancer in these areas. The study followed 159,840 participants over 15 years, during which researchers analyzed saliva samples to determine the type and quantity of oral microbes. Among these participants, 236 were diagnosed with head and neck cancer, and it was found that 13 types of oral bacteria were particularly linked to an increased risk of this type of cancer.

Although the researchers did not establish a direct link between the bacteria and cancer, they emphasized the importance of maintaining good oral hygiene to prevent these risks. They also pointed out the need for further research to better understand how these bacteria affect cancer cells and explore ways to prevent them from causing disease.

This study marks an important step toward promoting healthy oral hygiene habits, which could contribute to the prevention of various serious diseases, including some types of cancer.
