Meet the Dentists

Barbara T. Hauschka, DMD
General Dentistry

Barbara Toomey Hauschka, DMD earned her Doctor of Medicine in Dentistry degree at Tufts University School of Dental Medicine. After a year as a Research Instructor in Orthodontics at Tufts Dental School, she completed her Dental Residency at Forsyth Dental Center, and then joined Sowles Trauring / Dental Partners of Brookline.

While at Tufts, Dr. Hauschka won the Bates Day Research Award, the American Dental Association First Prize in Basic Science and Research in the student table clinic program, and the Johnson and Johnson Award to attend the International Association of Dental Research Meeting in Copenhagen, Denmark. She was also elected to the Omicron Kappa Upsilon National Dental Honor Society and was appointed Tufts Representative to the Dental Students’ Research Meeting at the American Dental Society Headquarters in Chicago.

Dr. Hauschka graduated from Goucher College in Baltimore, MD, where she was Senior Class President, and won the Woods Hole Award.

Love of Dentistry runs in Dr. Hauschka’s family. Her husband was on the faculty of Harvard Dental School, her son is a dentist in North Carolina, her sister is a hygienist in Washington DC, and her father was an orthodontist in Maryland. Several cousins currently practice dentistry in MD. The family has honored Dr. Hauschka’s parents with a scholarship in their names at the University of Maryland Dental School.

“My passion and excitement for Dentistry has deepened over the years with the advances in technology which give us the ability to treat patients and their dental problems more easily, comprehensively and thoughtfully. Dental Implants, for example, have completely changed the way we understand the future of dentistry and the way we plan for our coming needs. We expect to lose few, if any teeth; never have a denture, and always look great and function well. And now we can achieve this for our patients! To give someone their smile back, or the ability to chew again is life changing for them, and a privilege for me. It is an exceptional time to be a dentist, and a dental patient!”

In 2005 , Dr. Hauschka helped to lead a team of dental students through the Tikal Region of Guatemala, volunteering dental care to many in need of proper oral health.  She is recognized as one of the leading restorative and cosmetic dentists in the Boston area.

When not practicing dentistry, Dr. Hauschka loves spending time with her family, at her book club, and gardening.
