I went to see a dentist for the first time in years for a toothache and bleeding gums. He told me I have inflamed gums and an abscess in my mouth caused by diabetes. I may need a root canal and a tooth extraction. How can this be? I was diagnosed with Diabetes 16 years ago. I am almost 30 now and do not have dental insurance. I didn’t know having diabetes can affect my teeth. Is there anything I can do about it? I don’t want to lose any teeth!
