Teeth, jaws and the like
I had my first dental checkup in three years, and my teeth remain fine. Tech level has advanced again: I was given a small plastic-wrapped CCD imager to hold in my mouth for the X-rays, rather than a film holder, and my teeth were on a laptop screen within moments.
If I read the notes on the X-ray source correctly, it's 65keV; hc/E is then about 0.2 angstroms, which seems a surprisingly hard X-ray - I'm used to CuKa sources at 1.54A and synchrotrons that run at 1.00A. Does anyone have a reference for the X-ray absorption spectrum of air?
The toothache-like thing that has afflicted me for the last month is not tooth-related, but inflammation of the socket of the ball-and-socket joint at the right-hand side of my jaw; I'm told a major cause of this is grinding one's teeth together at night out of stress. I can take ibuprofen and hope it goes away, I can meditate constantly on the need to keep my teeth slightly apart when doing anything other than eating, or I can get the dentist to have made for me a small plastic cap to keep my teeth from grinding.
Generic ibuprofen costs 10p a tablet, and I should take three tablets a day. The custom-made small plastic cap costs three hundred pounds; it appears to be patented in such a way that it has to be manufactured by American dentists at USAnian-health-care costs.

It is suggested that the root cause of this is some kind of stress, and that the kind of massage which would relax my neck and back muscles would be a useful way of dealing with this.
Do you happen to know where in Cambridge such things can be found?
