About Dr. Mark C. Johnsen, DDS

Routine cleanings and unexpected toothaches don’t wait for convenient moments. Dr. Mark C. Johnsen, DDS offers both preventive care and urgent treatment in the same office, so Highland residents can schedule check-ups or walk in when discomfort flares. The practice sits at 6982 Boulder Ave, a quiet stretch where the foothills begin to rise above the valley floor.

Dentistry here covers everything from digital X-rays and sealants to crowns and simple extractions. Patients who need root canals or bridges can have the work done without a separate referral, which cuts down on extra appointments and travel time. Local families often choose the same provider for pediatric exams and adult restorations, keeping records in one place.

If you’re new to the area or simply ready to switch, call (909) 862-2121 to set up an initial visit. The office can answer questions about insurance, payment plans, and what to expect during the first exam. Highland’s mix of long-time homeowners and younger families means the waiting room is usually a low-key cross-section of the neighborhood.

Directions are straightforward once you plug the address into your phone, but the maps listing can help avoid backtracking: https://www.google.com/maps/place?ftid=0x80c355483fd605d5:0x10e6c53dc57ef673. Most people find the building on the first try, even if they’ve never driven past it before.
