Hello tarannum, Gingivitis in diabetic patients are common. This is the condition in which gums are inflamed due to accumulation of food debris and plaque. I Would suggest you to get a routine dental check-up as well as scaling done by your dentist. To prevent gum infections further,use soft-bristled toothbrush and clean your teeth involving all aspects of teeth. Use chlorhexidine mouthrinse to gargle. Rinse your mouth after every meals. Use warm saline to gargle. Antibiotics has to be taken to make your gums intact as per dentist s prescription. Take care.
