Dr. Liza Isaac

Root canals and advanced pulp therapy aren’t the kind of services most people browse for fun, but when the need arises, Dr. Liza Isaac specializes in precisely that. As an endodontist, her practice zeroes in on the inner workings of teeth—diagnosing tooth pain, performing root canal treatments, and handling dental trauma cases that general dentists might refer out. The focus here is narrow by design, catering to patients whose issues extend beyond routine cleanings or fillings. Whether it’s a cracked tooth with exposed nerves or a stubborn infection resisting antibiotics, this is where the more intricate dental work happens.

The office operates out of 349 E Northfield Rd Suite #211, Livingston, NJ 07039, a stretch of Northfield Road that’s home to a mix of medical practices and small businesses. Livingston’s layout means you’re never far from a café or pharmacy if you need to grab a coffee or pain relievers before or after an appointment. Parking in the area follows the usual New Jersey rules: expect shared lots and the occasional hunt for a spot during peak hours. The suite number suggests a multi-office building, so double-checking the directory upon arrival saves a few extra steps.

Scheduling an evaluation or procedure is a matter of calling (973) 731-4800—no online booking forms or chatbots to navigate. For first-time visitors, mapping the route in advance helps, especially if you’re coming from Route 10 or the nearby mall traffic. The directions will confirm what locals already know: Northfield Road is one of those roads that feels longer than it looks on a map. Bring your dental X-rays if you’ve had recent imaging; it’s one less thing to repeat.
