Get StartedOral health: A window to your overall health
Gum disease can let bacteria enter your bloodstream and wreak havoc elsewhere in your body. Or sometimes, signs of a disease may first show up in your mouth.
By Mayo Clinic staffAlthough the eyes may be the window to the soul, your mouth is a window to your body's health. The state of your oral health can offer lots of clues about your overall health. Oral health and overall health are more connected than you might realize.
Your oral health is connected to many other health conditions beyond your mouth. Sometimes the first sign of a disease shows up in your mouth. In other cases, infections in your mouth, such as gum disease, can cause problems in other areas of your body. Learn more about this intimate connection between oral health and overall health.
The connection between oral health and overall health
Your mouth is normally teeming with bacteria. Usually you can keep these bacteria under control with good oral health care, such as daily brushing and flossing. Saliva also is a key defense against bacteria and viruses. It contains enzymes that destroy bacteria in different ways. But harmful bacteria can sometimes grow out of control and lead to periodontitis, a serious gum infection.
When your gums are healthy, bacteria in your mouth usually don't enter your bloodstream. However, gum disease may provide bacteria a port of entry into your bloodstream. Sometimes invasive dental treatments also can allow bacteria to enter your bloodstream. And medications or treatments that reduce saliva flow or disrupt the normal balance of bacteria in your mouth also may lead to oral changes, making it easier for bacteria to enter your bloodstream. Some researchers believe that these bacteria and inflammation from your mouth are linked to other health problems in the rest of your body.
