Thomas LaMartina DDS, FAGD

Dr. Thomas LaMartina grew up in the St. Louis area and completed his undergraduate work in Springfield, MO. He is a 1995 graduate of the University of Missouri at Kansas City School of Dentistry. After graduation, Dr. LaMartina entered a General Practice Residency through Washington University at Barnes-Jewish and St. Louis Children’s Hospital. In 1997 he relocated to Farmington, Missouri with his wife and family. In 2004, Dr. LaMartina moved from a downtown location to a new facility near the Farmington High School on the corner of Westmount Drive and Doctor’s Drive. The practice then took the name Westmount Dental Arts which has evolved into one of the most respected dental practices in the Parkland.

Through years of continuing education, Dr. LaMartina has achieved the Fellowship award in the Academy of General Dentistry. Only 7% of general dentists reach this level of continuing education. 

At Westmount Dental Arts we have always put the patient’s interest first by treating them like a family member. In dentistry, there are frequently a number of directions that a treatment plan can go. We present the treatment options and recommendations, then have the patient direct how and when to proceed. Rest assured, that any recommended treatment option is one that the doctor would present to his own family in similar circumstances.

In addition, Dr. LaMartina practices in collaboration with a network of the area’s most talented specialists. If there is ever a situation best handled by a medical or dental specialist, we will only recommend another doctor that has earned our respect and trust through a history of excellent patient care.
