Brush your teeth! Bad oral hygiene linked to cancer, heart attacks and renal failure

It’s normal to have bacteria in your mouth. But harmful bacteria have been linked to a host of health problems, said medical scientist Glenda Davison and microbiologist Yvonne Prince, who have researched the oral cavity. They also explain why it’s so important to practice good oral hygiene. Abnormal bacterial communities in the oral cavity have been linked to liver disease, renal failure, cancers, heart disease and hypertension. Good dental hygiene includes regular dental check-ups, preventing the build-up of plaque by brushing your teeth regularly, and avoiding foods high in carbohydrates and sugar, which can lead to increased tooth decay and cavities.
