The mission of Interfaith Dental Clinic is to create a healthier community by providing transformational oral health care for those experiencing poverty.


Interfaith Dental Clinic’s vision is that every individual has the opportunity to achieve and sustain a healthy smile.


After doing volunteer dentistry in third-world countries, our founder Dr. Tom Underwood realized that there were hardworking people right here in Middle Tennessee that were in just as desperate need of dental care but could not afford it. With the help of the Nashville Dental Society and the Outreach Commission of West End United Methodist Church, Dr. Underwood initiated Interfaith Dental Clinic in November 1994 to provide affordable dental care for working poor families and the elderly who fall between the cracks of private practice and public healthcare.

The clinic started with a two-chair operation and one employee in the basement of West End United Methodist Church. In 1998, Interfaith Dental Clinic moved to 1721 Patterson Street and in 2012 opened a satellite clinic in Murfreesboro to serve the Rutherford County community. In 2019, the clinic expanded and moved into its current location at 600 Hill Avenue.  The clinics have 26 operatories and state-of-the-art equipment.

Who We Are

Dr. Tom Underwood

Dr. Thomas S. Underwood has spent more than three decades providing humanitarian service to people in need of dental care.

Dr. Underwood first volunteered overseas. He spent a month—including Christmas Eve 1975—volunteering in a dental clinic in an Israeli kibbutz. Only five years out of dental school at that time, young Dr. Underwood felt compelled to serve and his humanitarian calling took him around the globe for nearly 20 years to volunteer in places from Jamaica and Honduras to Kenya and Zambia.

“Then I realized how many people in my own state had worse oral health than the people I was treating outside the United States,” said Dr. Underwood. “So I thought we ought to do something right here, in a setting where we could follow up with patients and offer comprehensive dental care.”

With support from the Nashville Dental Society and the outreach commission of the West End United Methodist Church, Dr. Underwood founded the Nashville Interfaith Dental Clinic in 1994. The clinic’s original home was in the church’s basement.

“In the past 13 years, thanks to Dr. Underwood’s passion and commitment, Interfaith Dental Clinic has grown from a small, part-time clinic located in a church basement to a dental program that owns its own 7,500 sq. ft. facility, has 35 employees, uses more than 250 volunteers, and provides comprehensive, affordable dental care to more than 1,200 patients each year,” said Interfaith Dental Clinic CEO Dr. Rhonda Switzer-Nadasdi.
