Good oral hygiene helps you keep your mouth healthy, preventing dental decay and gum disease. Here, our North York dentist Dr. Davide Amato explains how a healthy mouth is good for your overall health, too.
Practicing good oral hygiene is key to maintaining oral health, and keeping your teeth as you age. But research has shown that good oral hygiene can have a positive effect on the health of the rest of your body as well.
A Healthy Salivary Flow
Saliva is a helpful diagnostic tool, in that it can help doctors and dentists to identify and diagnose systemic diseases before their symptoms become apparent.
In addition, saliva can help disable bacteria and viruses before they enter your system. In fact, saliva is one of your body’s main defences against disease-causing organisms.
Saliva contains antibodies that attack viral pathogens, such as the common cold, and even HIV. It also contains enzymes that destroy bacteria in several different ways, for instance by degrading bacterial membranes, disrupting vital bacterial enzyme systems, and inhibiting the growth and metabolism of some bacteria.
Keeping your salivary flow healthy is quite easy for most people. They key is to stay hydrated! Make sure you drink plenty of water throughout the day to maintain a healthy salivary flow.
Dental Plaque & Infection
Your mouth houses over 500 species of bacteria that are constantly forming dental plaque, a sticky, colourless film that clings to your teeth and causes a variety of health problems.
If you don’t brush and floss your teeth regularly and thoroughly, you’re allowing dental plaque to build up between your gums and teeth, eventually leading to a gum infection called gingivitis. Left unchecked, gingivitis can lead to a more serious infection called periodontitis (gum disease).
If you have periodontitis, simply undergoing a dental treatment or just brushing your teeth can provide a port of entry for the abundant bacteria in your mouth to enter your blood stream.
If your immune system is healthy, the presence of oral bacteria in your bloodstream will not cause problems. However, if it has been weakened, for example by a disease or by cancer treatment, oral bacteria in your bloodstream may cause you to develop an infection in another part of your body.
Infective endocarditis, which is when oral bacteria enter the bloodstream and stick to the lining of diseased heart valves, is an example of this.
Dental Plaque’s Link to Common Conditions
Poorly Controlled Diabetes
Chronic gum disease may make diabetes more difficult to control. The infection may cause insulin resistance, which can disrupt blood sugar control.
Bacteria in the mouth may cause inflammation throughout the body, including the arteries, meaning gingivitis may play a role in clogged arteries and blood clots.
In addition, gum disease and tooth loss may contribute to the development of plaques in the carotid artery.
