David J. Ahearn, DDS
Founder
Perfect Smiles was founded in 1993 by Dr. David Ahearn with a clear vision: to create a dental practice where advanced care, comfort, and innovation come together. As the practice grew, that vision expanded with the addition of a second location in 2010, allowing Perfect Smiles to serve even more patients with the same commitment to excellence.
With decades of experience in cosmetic and restorative dentistry, Dr. Ahearn built Perfect Smiles on the belief that dentistry should continually evolve. His dedication to lifelong learning set the standard for the practice, establishing a culture of ongoing education that remains a cornerstone of Perfect Smiles today. The team collectively devotes more than 60 hours every 90 days to continuing education, ensuring patients benefit from the latest techniques and technologies.
A defining part of Dr. Ahearn’s legacy is his focus on patient comfort, particularly for those who experience dental anxiety. He was instrumental in making sedation dentistry an integral part of care at Perfect Smiles, offering inhaled sedation (“laughing gas”), oral sedation, and IV sedation—options that have helped countless patients feel at ease in the dental chair.
Dr. Ahearn’s passion for innovation extended beyond his own practice. Recognized as a leader in dentistry, he has taught advanced programs nationwide and frequently served as a featured speaker at American Dental Association (ADA) events, sharing his expertise and enthusiasm for the profession.
He is also the founder of Design Ergonomics, a nationally recognized leader in high-performance dental office design. Through this work, Dr. Ahearn has influenced dental productivity and practice design across the country, creating spaces that seamlessly integrate modern dental knowledge, technology, and efficiency.
