Dental care peoject

Hi . I am am a 50 years lady . I am suffering from teeth infections on and off and I am loosing my teeth .I am constantly in pain and I don't know why to do . As I am diabetic I ait is hard when you can't eat because my teeth and gums are always pain. Something my face is swollen due to teeth abscess and It happens constantly. I have lost confidence because people look at me strangely. Not knowing it is something out of my control
