Dent-OX is a U. S. dental directory and marketing service designed to help patients find dental practices and help practice owners attract new patients.

Its directory draws listings from the federal National Provider Identifier registry and lets users search by town, ZIP code, location, or dental need. Patients can sort nearby practices by distance, filter by specialties such as orthodontics, pediatric dentistry, endodontics, and oral surgery, and send an appointment request to practices that have claimed their listings. Searching and being listed are free for patients and practices, and listings cannot pay to rank higher.

Dent-OX also provides plain-language patient guides covering treatment costs, insurance, dental emergencies, and choosing a dentist. For dental professionals, the company offers SEO and marketing services, practice-growth support, plans, listing claims, local competition information, and a free website leak check. The directory does not copy reviews or photos from other sites; practice contact details and hours are supplied by practices or sourced from openly published information
