The most common consequences of having high glucose levels, regarding the impact on oral health are: gum disease and periodontal disease, the appearance of mouth ulcers (mouth sores), infections caused by diseases, Scarring, dysfunction of the salivary glands, etc.
Scientific studies show that patients with diabetes are four times more likely to develop periodontal and gum disease than healthy patients.
Glucose is present in the saliva. When diabetes is not controlled, high glucose levels in the saliva help harmful germs grow, leading to plaque formation. Bacterial plaque causes acidity that attacks the gums. Gums become inflamed and tend to separate from the teeth forming bags that grow deeper over time – filled with germs which causes gingivitis.
Recent studies also indicate that there is a vicious circle between diabetes and advanced gum disease. People with diabetes are not only more susceptible to advanced diseases of the gums, but the organisms in the presence of an infection such as gingivitis, reacts with a series of reactions which may lead to an increase in the amount of blood glucose. This makes it difficult for the diabetic person to control blood glucose.
