Erin Waid spent years in nursing, dermatology research, and general dentistry before finding her calling in endodontics. Today, she treats some of the most complex dental cases while advocating for the kind of early care that could prevent them.
The roots of a tooth extend below the gumline, invisible to the patient sitting in the chair. By the time pain becomes unbearable, infection has often taken hold deep within the pulp, where nerves and blood vessels reside. Erin Waid works in this hidden architecture. As an endodontist practicing in Salem and Portland, Oregon, she diagnoses and treats conditions that begin long before they announce themselves.
Her path to this specialty was neither direct nor predictable. Before she ever picked up a dental drill, Waid earned a Master of Science in Nursing from Seattle University and worked as a Family Nurse Practitioner. She coordinated clinical trials in dermatology. She taught dental students at Oregon Health & Science University while treating patients in a community clinic. Each phase built on the last, guided not by a master plan but by a recurring instinct: the desire to understand not just what was happening to a patient, but why.
From Belle Chasse to the Clinic
Waid grew up in Belle Chasse, Louisiana, a small community in Plaquemines Parish just south of New Orleans. Her father, Brian Waid, ran his own law practice first in Louisiana, then later in West Seattle after the family relocated to Washington. Her mother pursued a Master’s in Early Childhood Education at the University of Washington. The household valued education, persistence, and service.
In high school at Holy Names Academy in Seattle, Waid ran cross-country. She describes the sport as formative in ways that extended beyond fitness. It taught her consistency. Results did not appear overnight. Progress required showing up every day, even when improvement felt incremental.
She enrolled at the University of Portland, earning a Bachelor of Science in Biology. From there, she moved into nursing, completing her graduate degree at Seattle University, where she was later nominated for the Graduate Student Excellence Award based on her academic performance and community outreach. Nursing offered what she sought: direct patient interaction, hands-on problem solving, and the ability to make a tangible difference in someone’s day.
Research, Dermatology, and the Pull Toward Procedure
After graduate school, Waid joined Oregon Health & Science University as a Research Assistant II in 2007. Two years later, she transitioned to Baker Allergy, Asthma & Dermatology in Lake Oswego, first as a Clinical Research Coordinator and then as a Family Nurse Practitioner. She worked on clinical trials, managed patient care protocols, and learned how treatment efficacy varied across individuals. The experience sharpened her interest in the mechanisms behind clinical outcomes.
She later worked at Pearl MedSpa in Portland, continuing her practice as a Family Nurse Practitioner until 2018. But during those years, a shift was underway. Waid found herself drawn to procedures, to the tangible act of solving a problem with her hands. Nursing had given her a foundation in patient care and systemic thinking. Now she wanted something more procedural, more problem-focused.
Dentistry emerged as the answer. She applied to Oregon Health & Science University’s School of Dentistry and was accepted. The decision meant starting over in many ways, but it also meant integrating everything she had learned. She earned her Doctor of Dental Medicine degree, receiving the Award in Oral Biology from the Integrative Biomedical and Diagnostic Sciences Department for her aptitude and promise in education and research.
Teaching, Treating, and Finding a Specialty
Upon completing her dental degree in 2018, Waid joined the faculty at OHSU as a General Dentist and Assistant Professor at the Russell Street Clinic. She treated patients while teaching dental students, a dual role that allowed her to refine her clinical skills and share what she was learning in real time. The position lasted until 2022, during which she also worked briefly at Emergency Tooth Doctor in Hillsboro, treating urgent dental cases that often arrived in advanced stages of decay or infection.
It was during this period that Waid began to notice a pattern. Many of the cases she encountered could have been less severe if addressed earlier. Patients arrived in pain, often after delaying care. By that point, the treatment required was more invasive, more complex, and more costly. The realization pointed her toward endodontics, a specialty focused on saving teeth through root canal therapy, retreatment, and microsurgery.
She returned to OHSU to complete a Certificate in Endodontics, joining the Marshall Baumgartner Endodontic Study Group and becoming a member of the American Association of Endodontics. During her residency, she contributed to research that would later be published in 2025, including work on dental trauma and diagnostic imaging that appeared in journals such as Dentomaxillofacial Radiology and PubMed. One study she worked on earlier in her career, published in the Journal of the Society of Laparoendoscopic Surgeons, examined biliary complications and contributed to her understanding of procedural outcomes and variability.
In 2024, Waid began practicing as an endodontist at Salem Endodontic Associates in Salem and Multnomah Endodontics and Microsurgery in Portland. She performs root canals, retreatments, apicoectomies, and manages traumatic dental injuries. Her work often involves magnification, microsurgery, and advanced imaging to navigate the intricate canal systems within teeth.
The Case for Early Intervention
Waid has become an advocate for preventive care and patient education. In her view, oral health is not separate from overall health. Infections in the mouth can signal or contribute to systemic issues. Sensitivity, swelling, or discomfort may seem minor, but they can indicate deeper problems. She believes that many patients do not recognize these warning signs, and by the time they seek care, the condition has progressed.
Her nursing background informs this perspective. She looks at the full picture, considering how a patient’s medical history, medications, and systemic conditions might influence their oral health. She explains diagnoses in terms patients can understand, walking them through what is happening inside the tooth and why a particular treatment is necessary. This approach, she notes, helps patients feel more in control of their care.
In interviews and press coverage, including a 2026 article in Access Newswire, Waid has emphasized that education is as important as treatment. If patients understand what early symptoms look like and why they matter, they are more likely to seek care before a minor issue becomes a major one.
Service, Scholarship, and a Pageant Detour
Waid’s commitment to community service extends beyond clinical practice. From 2018 to 2021, she served on the Multnomah County Ryan White Planning Council, a board responsible for allocating approximately $3 million in federal funds to programs serving people living with or affected by HIV and AIDS. The role required balancing competing priorities, evaluating program effectiveness, and making decisions that directly impacted vulnerable populations.
Between 2012 and 2018, she volunteered as an evaluator and mentor for the Seafair Scholarship Program for Women, helping assess candidates and provide guidance. Her involvement with Seafair dated back further. In 2006, she was named Miss Seafair, a role that combined public speaking, community engagement, and scholarship recognition. The experience, which she later described in a 2006 interview with West Side Seattle, involved appearances, interviews, and outreach to elderly and youth communities. It was an unexpected chapter, one that taught her how to communicate in front of diverse audiences and navigate unfamiliar environments with composure.
She also received the Alumni Association Scholarship for Excellence from OHSU, awarded for leadership activities and community-based professional work, and the Dean’s Research Scholarship, which funded her research on sex differences affecting caries preventive therapies in children with severe early childhood caries. Her findings were later presented at the American Association for Dental Research Meeting in March 2016.
The Work Ahead for Erin Waid
Waid continues to practice in both Salem and Portland, treating patients referred by general dentists for cases that require specialized endodontic care. She remains active in professional organizations and contributes to ongoing research in her field. Her focus has shifted from acute intervention to a broader vision of care that includes prevention, education, and early diagnosis.
She maintains that the best outcomes in endodontics are the ones that never require her services in the first place. When patients understand their oral health, recognize symptoms early, and seek timely care, the need for complex interventions decreases. Her work, she notes, is often to treat infections and save teeth. But the larger goal is to create a system where fewer patients arrive in crisis.
For Waid, the path from nursing to dentistry to endodontics was less about reinvention and more about accumulation. Each role added a layer of understanding. Each experience informed the next. The result is a practice built on the belief that good care begins long before the patient feels pain, and that the best treatment is the one that addresses not just the symptom, but the whole person behind it.
