There are other huge benefits of brushing besides clean teeth

Oral hygiene could help to reduce risk of cancer

When you go to the dentist, you aren’t just taking care of your teeth -- there are other benefits that come from your visit besides the free toothbrush.

The truth is, your oral hygiene factors into many other aspects of your overall health and wellbeing. Poor dental health has been previously linked to increased cardiovascular health risk and even pneumonia, according to studies published in the Journal of Periodontology and British Dental Journal.

A different study published in the Annals of Oncology even found that good oral hygiene habits led to a modest reduction in the risk for head and neck cancer.

Faisal Ahmad, MD, a head and neck surgical oncologist at Baptist MD Anderson Cancer Center, said dentists often serve as the first line of defense against head and neck cancer through screening and helping to identify concerning signs and symptoms. These include:

  • White or red lesions on the tongue, gums or lips.
  • Pink, white or red sores that tend to bleed easily.
  • Sores in the oral cavity area that don’t heal.
  • Numbness in the teeth, tongue or lips.
  • Difficulty moving the jaw or tongue.
  • Loose teeth or changes in how dentures are fitting.

These symptoms may be due to poor oral and dental health, but they could also be indicators of larger health issues, as some head and neck cancers can first present this way as well, Ahmad said.

If patients are diagnosed with head and neck cancer, dental visits before, during and after treatment are critically important, according to Ahmad.

In general, radiation, often used as part of the treatment for head and neck cancer, adversely affects your body’s ability to recover from dental and oral cavity issues by decreasing saliva production and making it harder for tissues to heal after problems develop. Getting any necessary dental work done before radiation begins may reduce the risk of developing more serious problems during treatment.

During and after treatment, you may need to see a dentist to deal with side effects, including dry mouth, cavities and loss of taste, according to the National Institutes of Health.

“The bottom line is that dental visits allow for early evaluation and diagnosis of health problems in the head and neck,” Ahmad said. “Catching problems early is always a great thing, and practicing good oral hygiene is an important part of an overall healthy lifestyle.”
