I spent a lot of money on my teeth before being diagnosed with diabetes, I may have had it and it was not diagnosed but I grew up being teased for crooked teeth so when I became an adult and employed I paid a lot of money to have my teeth straightened. I'm on metformin and my diabetes is somewhat controlled, but my heart is broken as all of my teeth began cracking off within a 2 yr period of time since the diabetes. 3 have cracked off to the gum line and my dentist is sending me to an oral surgeon to have the 3 teeth cut out. Iam so scared. I have Cardiomiopathy also. You said the sockets in your gums became infected, did they prescribe an antibiotic before pulling your teeth? And would you advise having all 3 pulled at the same time? That seems like it would be more difficult to heal. My dentist is not very sympathetic and said he has not dealt with a diabetic and heart patient before. So Iam terrified. Have you had all your teeth pulled out? I want to save as many teeth as I can.
