The root of the problem

I had a 9am dental appointment in Edinburgh so managed an early morning misty photo of the castle.

For anyone interested in my dentistry issue - my local dentist referred me to specialists who use microscopes and other fancy tech. to (hopefully) sort out a tooth which has already had 2 shots of root canal treatment.  The dentist today found a 4th root that hadn't previously been filled and showed me a 'lovely ' close up photo of it.
