Our Dental Office


Our office is a 1600-square-foot facility that Dr. McArdle acquired in the year 2000 and features a beautiful view of Portsmouth's North Mill Pond. The suite was renovated that year to Dr. McArdle's exact specifications with hospital standard grade materials in all patient treatment areas. There are four operatories (treatment rooms), all of which are private. Each operatory has its own x-ray unit for our patients' convenience and we also have a panoramic x-ray machine for the evaluation of impacted wisdom teeth and TMJ problems.


When last the New Hampshire State Board of Radiological Health conducted an inspection of the x-ray equipment in Dr. McArdle's office, it was found that patient exposure-at-skin-entrance (ESE) radiation levels were, on average, well BELOW established safety guidelines. These findings are most probably attributable to the fact that Dr. McArdle has ALL the apparatus in his office, including his five x-ray units, serviced by qualified dental equipment technicians on a semiannual basis and now uses digital x-ray technology that requires even less radiation than traditional systems.


Our laboratory and sterilization areas are separate, with surgical guides for some implant cases and bleaching trays made in-house. We sterilize our instruments between patients by means of the pressurized steam method in an autoclave, which is monitored weekly for quality control. A back-up unit is kept ready on-site.

Our office possesses a uniquely flexible music system that features the ability to play CDs, FM radio broadcasts and 150 channels of digital music in a multitude of styles accessed from the internet. You can request a certain type of music be played at your visit to our office or you can bring in a favorite CD for us to play while you are here. We will honor your request (within reason) so long as it is compatible with our office atmosphere and is agreeable to other patients present in the office.
