Why this episode matters
For many people, the words “root canal” bring instant fear. But what if that fear is based on outdated myths? In this episode, Dr. Allan Acton sits down with Dr. Cristina Maresca, founder of Peak Endodontics in Apex, North Carolina, to unpack the truth about root canals—what they actually do, why they’re not painful anymore, and how new technology has completely changed the experience.
Dr. Maresca shares her story from general dentist in Colombia to highly trained endodontist at UNC Chapel Hill, where she fell in love with the art and science of saving teeth. Today, she helps patients overcome pain, anxiety, and infection using precision tools, 3D imaging, and laser-assisted treatment—all while proving that root canals can be quick, gentle, and life-changing.
