Gabe et al,
Just to clarify that there is no distinction between DDS and DMD, about 25 years after graduation, my dental school offered me the opportunity to change my degree to DMD as that was the degree that they were now awarding. I of course refused, as there was no need to do it. Unfortunately, many people assume wrongly that there is a difference and the "MD" part of the degree leads them to assume that.
Brian, DDS actually stands for Doctor of Dental Surgery. It's very often that the abbreviation is confused.
Meredith, hope you have seen your dentist by now and the tooth is feeling better.
