I'm Kara too with a K. (I was actually named Cara, but the strict Irish priest wouldn't baptize me saying that I needed a name derived from a saint - so my parents changed the spelling. I thought at one time I had Reynauds - twice one of my fingers turned blue - but my platelets were very high so apparently that was the cause. I hope my new fillings don't come loose. They are in my molars so I think they are set better than one on the front top of a tooth. Thanks for the link - the testimonials are very interesting.
