Diabetic patients with stable blood glucose control can have their teeth extracted without any significant adverse consequences, but poor blood glucose control may lead to infections and delayed wound healing. If the diabetic blood sugar control is poor, the body’s sugar metabolism is disturbed, it will be easy in the extraction process, after the complication of infection, will also lead to delayed healing of the wound after the extraction of the wound and so on. Diabetic patients should take glucose-lowering drugs such as gliclazide, metformin or insulin injection as prescribed by the doctor, and can have their teeth extracted after controlling their blood sugar within a reasonable range with dietary control. Therefore, diabetic patients should stabilize their blood sugar control before tooth extraction, which can help to avoid the adverse consequences of tooth extraction. Diabetic patients who need tooth extraction should choose regular hospitals.
