Any kind of inflammation in the mouth, rotten teeth, tartar presence are among the conditions that make diabetes difficult to control and sometimes even cause it to get out of control on its own. A person with diabetes must be under routine dentist control. A diabetic who has not had tartar cleaning done for a long time has all of their gums edematous and bleeding. This means that there is a wound area the size of the person's own palm. In this case, it makes it impossible to control diabetes for sure.
