About Rio Mar Dental

Dental care in north Fullerton doesn’t require a long commute—Rio Mar Dental sits just off Commonwealth Avenue, where routine checkups and more involved procedures are handled under one roof. The stretch of West Commonwealth near Placentia Avenue is lined with practical businesses, making it easy to combine a dental visit with errands or a quick bite nearby. Cleanings, fillings, and crowns are all part of the practice’s scope, though specifics are best confirmed directly with the office. Parking in this area tends to be street-level, with metered and permit-free spots scattered along the side streets.

Fullerton’s mix of historic homes and mid-century commercial strips gives the neighborhood a lived-in character, and dental offices here often serve multigenerational families. While the focus remains on general dentistry, practices in this part of town typically address everything from pediatric exams to basic cosmetic adjustments. The proximity to Cal State Fullerton also means students and faculty occasionally pop in between classes—though appointment availability, of course, depends on the day. For those mapping out their route, the intersection of Commonwealth and Harbor Boulevard is a useful landmark; the office is just a few blocks west.

Booking a visit is as simple as calling (714) 578-6768 during business hours, and first-time patients might want to verify accepted insurance plans upfront. The map pinpoints the entrance between a tax prep office and a long-standing taqueria. No frills, just dentistry—exactly what you’d expect from a neighborhood practice.
