Root causes

Dental problems and unhealthy gums may lead to cancer and other whole-body issues, says Dr Leigh Erin Connealy. Here’s how to keep your gums and health in the pink

Dentists have long recommended brushing and flossing daily to prevent tooth decay. But there may be an even more pressing reason to clean up your oral health: it may help prevent the development of certain cancers.

Researchers at Harvard’s T. H. Chan School of Public Health reviewed two extensive studies of more than 150,000 men and women. Following up after 22–28 years, they found those who had gum disease were 43 percent more likely to be diagnosed with esophageal cancer and 52 percent more likely to develop stomach cancer.

More studies are needed to confirm the link between gum disease and cancer, but it certainly makes sense. The mouth is the start of the gastrointestinal (GI) tract, and oral health issues can trickle down into other areas if left untreated.

For instance, if you have old dental amalgam fillings, chances are they contain mercury. Many integrative doctors and biological dentists believe this dangerous metal may be released in tiny particles each time you chew or brush your teeth. The minuscule particles can leach into your brain and other areas of the body and wreak havoc.

The following are examples of common, yet often overlooked, health issues associated with mercury exposure:

• Neurological problems

• Headaches

• Memory loss

• Depression

• Fatigue

• Muscle weakness

• Tremors

Dental infections caused by root canals, jaw diseases, wisdom tooth extractions or other procedures can also cause problems. These pockets of infection, sometimes referred to as focal or foci infections, typically don’t show up on lab tests. Still, they produce toxins that can result in increased inflammation and potential cancer risk.
