Our Practice

We are a well-established family dental practice that initially opened its doors in Centrepointe in 1995. Dr. Barta-Sima joined the practice in 2006.

In October 2014, Barta-Sima Dental Care relocated to 96 Centrepointe Drive in a new, spa-like state of the art office offering convenient free parking and wheelchair access.

Our team of highly trained and experienced dental professionals provide exceptional Family/General Dentistry to all ages, from young children to the elderly, and to anxious patients.

We are committed to quality, gentle patient care in a modern, relaxed atmosphere.

We respect our patients wishes and concerns. When you are in our dental chair, YOU are the most important person in the room. We take time to listen to your wishes and concerns, we provide you with information regarding treatment options, alternatives and possible outcomes, and we assist you in choosing the best treatment plan according to your goals, for optimal, long term oral health.

We recognize each patient as an individual, and as such, we customize our treatment and preventive approach for the maximum benefit of each of our patients.
