About J. Keith Espinosa, DMD
Dental care in Sussex County spans from routine cleanings to more specialized treatments, and J. Keith Espinosa, DMD fits into that landscape with a practice situated above High Street in Newton. The second-floor office at 183 High St #2100 places it among the professional suites near the county’s administrative hub, where parking and accessibility align with the area’s mix of historic and modern buildings. General dentistry here covers the expected—exams, fillings, crowns—without the frills of a spa-like experience or the narrow focus of a boutique specialist. For those mapping out their next checkup or a long-overdue procedure, the location’s proximity to the courthouse and Spring Street makes it a logical stop between errands.
Newton’s downtown has seen its share of changes, but dental practices remain a constant, and this one keeps its listing active for anyone searching by name or service. Questions about insurance, emergency slots, or sedation options would go through the front desk, where the phone connects directly at (973) 383-7900. Directions are best pulled from the map here, since GPS can be finicky with second-story suites in older buildings. Around town, it’s just another name on the list of places where people quietly mark their calendars twice a year.
