Maria J Fournier, DDS, MS, LTD

Along the North Arlington Heights Road corridor, where medical offices sit between retail strips and quiet residential blocks, Maria J Fournier, DDS, MS, LTD specializes in endodontics—a field that rarely gets the spotlight but handles some of the most urgent dental needs. Root canals, traumatic dental injuries, and persistent tooth pain often land patients in an endodontist’s chair, and this practice focuses squarely on those precise, technical treatments. The office occupies suite 407 at 3275 N Arlington Heights Rd, Arlington Heights, IL 60004, a location that’s easy to overlook unless you’re specifically searching for advanced dental care beyond general cleanings or fillings.

Most people only think about endodontists when referred by their dentist, but the work done here—diagnosing tooth pain origins, performing microsurgeries, or retreating failed root canals—can mean the difference between saving a natural tooth and losing it. They don’t advertise walk-in whitening or routine exams; instead, the practice zeroes in on the kind of procedural work that keeps dentists’ referral networks humming. For questions or to schedule a consultation, the number is (847) 255-3374. First-time visitors might want to pull up the map beforehand, since the building’s professional suites aren’t always obvious from the street. Some things in dentistry are better left to the specialists.
