DIANA DONGELL D.M.D.

Meet Our Endodontist

I am inquisitive by nature, detail oriented, and stand behind my work. I was the valedictorian of my high school class, graduated magna sum laude with a degree in Biology from the University of Pittsburgh, finished in the top 10 in my dental school class at the University of Pittsburgh School of Dental Medicine and earned my certificate in Endodontics two years later from the same program. I have published research in peer reviewed journals and been named as one of the best dental specialists in the greater Washington DC, Pittsburgh and Lexington regions.
I founded Lexington Endodontics because I am passionate about what I do and love improving the patient experience!

Don’t wait on a toothache:

If you’ve ever had a toothache that just wouldn’t quit or found yourself cringing at the thought of biting into your favorite snack, you know the struggle. These symptoms are your body’s way of letting you know that something is wrong and expert care is needed. For patient’s in the Lexington, West Columbia, Columbia, Cayce, Irmo, and Aiken areas, scheduling an appointment with Dr. Dongell at Lexington Endodontics is the best place to start. When you respond quickly to those early whispers (or shouts) of discomfort, you are preventing the problem from escalating into a bigger, more painful issue. If a root canal is needed, most patients report that having a root canal is similar to getting a filling. A root canal relieves the pain, keeps your bite intact, and preserves your natural tooth.
