Periodontal Disease and Diabetes

A research study has shown that individuals with pre-existing diabetic conditions are more likely to either have, or be more susceptible to periodontal disease.  Periodontal disease can increase blood sugar levels which makes controlling the amount of glucose in the blood difficult.  This factor alone can increase the risk of serious diabetic complications.  Conversely, diabetes thickens blood vessels and therefore makes it harder for the mouth to rid itself of excess sugar.  Excess sugar in the mouth creates a breeding ground for the types of oral bacteria that cause gum disease.

Here are ways in which diabetes and periodontal disease are linked:

  • Increased blood sugar – Moderate and severe periodontal disease elevates sugar levels in the body, increasing the amount of time the body has to function with high blood sugar.  This is why diabetics with periodontitis have difficulty keeping control of their blood sugar.  In addition, the higher sugar levels found in the mouth of diabetics provide food for the very bacteria that worsen periodontal infections.
  • Blood vessel thickening – The thickening of the blood vessels is one of the other major concerns for diabetes sufferers.  The blood vessels normally serve a vital function for tissues by delivering nutrients and removing waste products.  With diabetes, the blood vessels become too thick for these exchanges to occur.  This means that harmful waste is left in the mouth and can weaken the resistance of gum tissue, which can lead to infection and gum disease.
  • Smoking – Tobacco use does a great deal of damage in the oral region.  Not only does tobacco use slow the healing process, it also vastly increases the chances of an individual developing periodontal disease.  For diabetics who smoke, the risk is exponentially greater.  In fact, diabetic smokers aged 45 and over are twenty times more likely to develop periodontal disease.
  • Poor oral hygiene – It is essential for diabetics to maintain excellent levels of oral health.  When daily brushing and flossing does not occur, the harmful oral bacteria can ingest the excess sugar between the teeth and colonize more freely below the gum line.  This exacerbates the metabolic problems that diabetes sufferers experience.
