Dr. David Pham, HBSc, DDS

Dr. David Pham completed his Honours Bachelor of Science degree at the University of Toronto with a double major in Human Biology and Psychology. Having grown up in Toronto, it was hard for him to make the decision to leave home to attend dental school in London, however he chose the Schulich School of Medicine & Dentistry because it had a reputation for developing strong clinical skills. He completed his Doctor of Dental Surgery degree with Distinction in 2016. Soon after graduation, he practiced in a small northern Ontario town for a year.

Although he will never forget his northern experience and the amazing people he met, it was the right time for him to return home. Dr. David Pham offers a variety of general dental services including endodontics, oral surgery, pediatrics, restorative and sedation with nitrous oxide or an oral sedative. He takes the time to make sure patients are comfortable before beginning any procedure. He enjoys staying up to date with new research findings and procedures through various continuing education programs throughout the year.
