There is a nice sketch of him in Portland, Oregon, its history and builders, by Joseph Gaston on pages 71 and 72, but since it emphasizes his involvement in further the profession of denistry as do other sources, I am going to focus on that for now. Of course, I cringe a little at the idea of writing about what dentists were thinking in the late 1890s, especially after I just chanced upon an article in which one dentist denied that teeth and their roots were connected to pain. His suggestion give up on anesthesia. Ouch.
Let's hope Dr. Barber didn't believe that. The first mention of his contribution to the field comes in 1893 when he is one of the founding members of the Oregon State Dental Association. While other dentist toast to Dentistry of the Past and Future, he gives the one on dentristy of the present. I like that sense of practicality already.
The next day, Dr. Barber is the first to give a clinic, which the Pacific Coast Dental journal reports on:
During a general discussion, the dentist engaged in a serious discussion of how to prevent infection. Dr. Barber emphasized infections in the gum around teeth could lead to death, even when the dentist had not first intervened. Since there was just a series of horrifying stories about this happening to a young boy in Maryland in 2008 or 2009, Dr. Barber was not wrong to point out the problem. Though I am not sure the doctors all had a very good solution. In Maryland there was no coverage for dental problems in children on public insurance; I assume the same was true in Oregon in 1893. It is encouraging to note that the last dentist to speak emphasized the importance of using boiling water to clean instruments.
Part of the point of forming the Oregon Dental Association was to unify the dentists; the Portland Dentists were already organized. Dr. Barber was President of the Statewide group in 1893, and treasurer of the Portland group in the same year.
And why did you need to unify the dentists -- so they could talk and learn from each other -- and make certain that the quacks stayed away. In 1887, the Oregon Legislature passed a law regulating dentists. Like many other professional groups of the time, then you needed a professional association to advocate in favor of good dentists and keep the bad dentists away. Something we can all appreciate.
