Oral health & overall health

In the past decade or so many researchers have come to realize that good oral health has very significant effects on the overall health of our bodies. It is extremely important to understand the intimate connection between oral health and overall health and what you can do to protect yourself. 
Your mouth is normally teeming with bacteria — most of them harmless. The body's natural defenses and good oral health care, such as daily brushing and flossing, can keep these bacteria under control. However, harmful bacteria can sometimes grow out of control and cause oral infections, such as tooth decay and gum disease. 
In addition, medical procedures, medications, or treatments that reduce saliva flow, disrupt the normal balance of bacteria in your mouth or breach the mouth's normal protective barriers may make it easier for bacteria to enter your bloodstream. 

Your oral health may affect, be affected by or contribute to various diseases and conditions, including:

• Endocarditis. Gum disease and dental procedures that cut your gums may allow bacteria to enter your bloodstream. If you have a weak immune system or a damaged heart valve, this can cause infection in other parts of the body — such as an infection of the inner lining of the heart.
• Cardiovascular disease. Some research suggests that heart disease, clogged arteries and stroke may be linked to oral bacteria, possibly due to chronic inflammation from periodontitis — a severe form of gum disease.
• Pregnancy and birth. Gum disease has been linked to premature birth and low birth weight.
• Diabetes. Diabetes reduces the body's resistance to infection — putting the gums at risk. In addition, people who have inadequate blood sugar control may develop more-frequent and severe infections of the gums and the bone that holds teeth in place, and they may lose more teeth than do people who have good blood sugar control.
• HIV/AIDS. Oral problems, such as painful mucosal lesions, are common in people who have HIV/AIDS.
• Osteoporosis. Osteoporosis — which causes bones to become weak and brittle — may be associated with periodontal bone loss and tooth loss.
• Alzheimer's disease. Tooth loss before age 35 may be a risk factor for Alzheimer's disease.
• Other conditions. Other conditions that may be linked to oral health include Sjogren's syndrome — an immune system disorder — and eating disorders.

Be sure to tell your dentist if you're taking any medications or have had any changes in your overall health — especially if you've had any recent illnesses or you have a chronic condition.
