Designed with You in Mind

Our Pittsburgh dental office uses leading edge technology to ensure that your treatment is nothing less than the most effective, efficient, and comfortable care possible.

Digital X-rays

We use digital X-rays for our patients’ comfort. There is no sharp X-ray film and the X-rays emit up to 90% less radiation than traditional X-rays. We are also able to work faster since images don’t require chemical processing, making them available in seconds.

Intraoral Cameras

Intraoral cameras give us a better view of areas of your mouth that are often difficult to see in a standard exam. They are an important part of our patient education as we use them to walk patients through diagnoses and treatment plans. All new patients receive a “tour of the mouth” with photos of every tooth.
