Good Oral Health is Important for Overall Health

Oct. 9, 2025

Good oral health is more important to overall health than it may seem. Studies link the health of gums, teeth and the mouth to other illnesses, such as heart disease and diabetes. 

If not maintained, oral health can impact overall health.      

Teeth, gums, the tongue and other soft tissues in the mouth are connected to the body via the bloodstream. Good oral health helps balance the good and bad bacteria in the body. Inflammation in the bone and supporting gums around your teeth can affect the immune system and other areas of the body. 

Prevention should be your main focus for oral health. Without proper care, you are at risk of many oral problems. These include, but are not limited to, cavities, gingivitis and other advanced forms of periodontal disease.

Visit a dentist twice a year for diagnostic care such as X-rays and clinical photographs. The Centers for Disease Control and Prevention (CDC) recommends brushing teeth twice a day* with fluoride toothpaste and flossing to remove plaque and help control and minimize bacteria. Brush your tongue as well to remove bacteria and keep your breath fresh.

Other tips for good oral health include these: 

People with diabetes should maintain the disease to decrease the risk* for gum disease and other complications. Treating gum disease may lower blood sugar levels, according to the CDC. 

Eating a variety of nutrient-rich foods also promotes healthy teeth and gums. Eat calcium-rich foods such as low-fat milk, yogurt and cheese. The minerals found in eggs, fish, lean meat and nuts can be good for teeth. 

Vitamin C helps the gums. Citrus fruits, tomatoes, peppers, broccoli, potatoes and spinach are good sources of vitamin C.

Take these steps to improve your oral health:

  • Visit a dentist this year. 
  • Ask for preventive screenings. 
  • Take advantage of diagnostic tools and services.
  • Schedule your next visit before you leave.
