Diabetes affects millions of people every year. Diabetes can cause problems with your mouth, eyes, nerves, kidneys and heart, as well as other parts of your body. It can lower your resistance to infection and slows down the healing process.

The most common oral health problem associated with diabetes is gum disease or periodontal disease.

Gum disease, is a bacterial infection of the gums, fibres, and bone that support and hold your teeth firm in the oral cavity. The main cause of this attributed to dental plaque, a sticky, colourless film that constantly forms on your teeth made up of variety of microorganisms. Toxins produced by the microorganisms in plaque irritate the gums, causing infection and pain and more commonly leads to bone loss and eventually tooth loss.

Gum Diseases is the sixth most common complication of diabetes. If you have diabetes, you are three to four times more likely to develop gum disease, and more related complications.

Periodontal disease usually makes it more difficult to gain control on your blood sugar. The diabetic person’s reaction to periodontal disease increases the blood sugar levels. Hence it is more important for people with diabetes to get treated and reduce or control gum related infections for better diabetes control. Periodontal treatment has shown to improve blood sugar levels in patients with diabetes through various researches, suggesting that treating periodontal disease could in fact decrease insulin requirements.

If your diabetes is well under control, treatment of your gum and related diseases is similar to those patients without diabetes. Diabetes retards healing and increases risk of infection. It is important that you update your dentist about your diabetic condition and the treatment you are undergoing with your physician and vice-versa on your oral condition and dental treatment, this makes both your dentist and physician can work together to help you control your diabetes and prevent and control oral diseases specially periodontal disease.
