About Dr. Aaron E. Isler, DDS

Dr. Aaron E. Isler and the team at his practice on Lake Underhill Road in east Orlando have built one of the more recognized endodontic practices in the greater Orlando metro, with a focus on delivering high-quality root canal therapy and endodontic care to patients across east and southeast Orange County. The practice is endodontic-only: Dr. Isler completed dental school followed by a full accredited endodontic residency, and his career since has been devoted exclusively to root canals, re-treatments, and related endodontic procedures. The Lake Underhill Road location is central to east and southeast Orlando, accessible from Waterford Lakes, Conway, Vista Lakes, the MCO airport corridor, and the residential neighborhoods south of SR 408. The practice is known for its ability to handle technically difficult presentations: heavily infected teeth that are difficult to anesthetize due to lowered tissue pH, calcified root canal systems requiring specialized file protocols, unusual root anatomy with extra canals, and teeth where prior root canal treatment has failed and retreatment is the last option before extraction. An operating microscope is used throughout all procedures, enabling a level of visualization that makes a material difference in finding all canal spaces and detecting micro-cracks that would change the prognosis. Emergency appointments for patients in severe tooth pain are typically available within 24 hours, because the practice understands that someone with an abscessed tooth cannot comfortably wait days for an appointment. Insurance is accepted broadly, and the billing staff submit endodontic claims accurately and follow up with carriers when needed. For patients who carry anxiety about root canal treatment — and many do — a direct conversation with this team before booking an appointment tends to reframe expectations around what the experience will actually involve.

Dr. Aaron E. Isler DDS specializes in root canal therapy and endodontic re-treatment using operating microscopes for east Orlando and southeast Orange County patients.

My daughter Nova had a root canal with Dr Isler today. She was so nervous but he made her feel calm, important, and reassured her. I was so worried she would be in distress, but she wasn’t because of him. The procedure took around 7 minutes and she left hearing that she was his best patient this year. Thank you Dr Isler for doing such a wonderful job on her tooth and thank you for treating her so well. You were so thorough and informative. We never met a kinder Dr.

Thank you Dr. Isler for an excellent experience. I was thinking this was going to be a very painful procedure however, it was a very quick and painless service. Doctor Isler explained in detail as he was working on my tooth. He was very pleasant as he was completing the procedure I needed it. The office staff was also very pleasant from start to ending this services rendered.

I went to see Dr. Isler about 7–8 months ago for a root canal, and I was honestly amazed at how quick and painless the procedure was. Root canals have a reputation for being painful, but that wasn’t my experience at all. Even several months later, everything still feels perfect. I’m really grateful for the care and professionalism. I highly recommend Dr. Isler, thank you again!
