You live and learn. That is the first time I have ever heard of “nosocomial” infections.
I had an aunt who drove the doctors to distraction with persistent infections after hip replacement. It was finally tracked down to a low level dental infection, and one less tooth later, her hip finally healed.
Now see, this is why I've always protested the fact that medical insurance is always separate from dental insurance. Why? It's been proven that dental problems can negatively affect the entire body. The mouth is part of the body. Oral health is just AS important. Other than dentists being able to charge more for dental treatment, I just can't see any logical reason for this. Dental should automatically be part of or included in medical insurance. And yet, it's always separate and more expensive. I could understand it if the procedure was merely cosmetic. Any cosmetic procedure should be more costly. But regular health issues dealing with teeth and gums? It should be considered the same as any OTHER part of the body.
