The link between your oral health and your overall health

It is easy to think of your teeth and gums as separate from the rest of your body. But your mouth is connected to everything else, and a growing body of research shows that oral health and general health are closely linked. Here is what you should know.

Your mouth as a window to your health

Dentists are often the first to spot signs of wider health problems. Changes in your gums, tongue or the soft tissues of your mouth can sometimes point to conditions such as diabetes, vitamin deficiencies or certain infections. That is one of the reasons regular check-ups matter.

Gum disease and heart health

Studies have found an association between gum disease and cardiovascular disease. One theory is that inflammation from gum disease, and bacteria entering the bloodstream through inflamed gums, may contribute to inflammation elsewhere in the body. Research is ongoing, but keeping your gums healthy is a sensible step for your overall well-being.

Diabetes

The link between diabetes and gum disease works both ways. People with diabetes are more likely to develop gum disease, and gum disease can make blood sugar harder to control. Treating gum disease has been shown to help some people with diabetes manage their condition. If you have diabetes, let us know, and keep up with regular check-ups and hygiene visits.

Pregnancy

Hormone changes during pregnancy can make gums more prone to inflammation and bleeding. Gum disease has also been associated with pregnancy complications. The good news is that NHS dental treatment is free during pregnancy and for 12 months after your baby is born.

Breathing and chest health

For older people and those who are frail, bacteria from the mouth can be breathed into the lungs, increasing the risk of chest infections such as pneumonia. Good oral hygiene is an important part of care for older relatives.

Oral cancer

Every check-up at Castle Street includes an oral cancer screening. Mouth cancer is much easier to treat when found early. See us if you notice an ulcer that has not healed within three weeks, red or white patches, or any unusual lumps or swelling.

Confidence and well-being

Oral health affects how we eat, speak, sleep and feel about ourselves. Toothache and missing teeth can have a real impact on quality of life.

Simple steps for a healthier you

  • Brush twice a day with fluoride toothpaste.
  • Clean between your teeth every day.
  • Keep sugary foods and drinks to mealtimes.
  • Stop smoking and keep alcohol within recommended limits.
  • See your dentist and hygienist regularly.
