Dr. Diana Cline

Endodontics occupies a quiet but critical niche in dental care—less about routine cleanings, more about saving teeth when deeper issues arise. While general dentists handle fillings and crowns, specialists like Dr. Diana Cline focus on the intricate work of root canals, dental trauma, and infections that lurk beneath the gumline. The field demands precision, and in a city where historic oak canopies shade streets just blocks from modern medical offices, this kind of expertise fits neatly into Jacksonville’s mix of old and new. Most patients arrive not by choice but by necessity, often after a persistent toothache or a cracked molar refuses to ignore.

The practice sits at 5911 Timuquana Rd STE 101, a stretch where the road widens enough to feel like a thoroughfare but still retains the low-key rhythm of a neighborhood artery. Timuquana’s location—tucked between the St. Johns River and the sprawl of Westside—means it’s as accessible to downtown commuters as it is to residents in the quieter pockets of 32210. Appointments here start with a call to (904) 777-5878, where the conversation likely pivots quickly from scheduling to the specifics of pain or prior treatments. For those mapping the route, the office’s exact location sits just past the intersection where Timuquana meets Roosevelt, where the signage is unassuming but the purpose is anything but.
