Diabetes, as we all know greatly affects the whole body including 
your oral health. The lack of proper dental hygiene can cause gum 
disease or Periodontitis which can result in painful chewing 
difficulties and even tooth loss.
For patients with diabetes, watch out for dry mouth, for it is a 
symptom of undetected diabetes that causes soreness, ulcers, infections 
and tooth decay.
Research shows that people with diabetes are susceptible to 
Periodontal disease. It can also potentially affect the level of blood 
glucose in the blood and contribute to the progression of diabetes.
Thus, people with diabetes have a higher risk of gum disease and have
 immune systems that have a weak ability in fighting bacteria that 
invades the gums.
Diabetes can take a toll on your entire body when your blood sugar is
 high. The good thing is, prevention is in your hands if you take charge
 of your dental health.
