What Sets Our Dental Office Apart


Young woman with a healthy, radiant smile.Our smiles are part of our identity. They are the first thing people notice when you meet them, and make a lasting impression. Our smiles are the way we show the world our health, our happiness, and our confidence.

You deserve a smile that radiates health and assurance; a smile that grows your self-esteem and puts others at ease. At our dental office in Bay Shore, NY, we’ll help you achieve optimal oral health and, with it, a smile you’ll share with joy.


Dr. Daniel P. Duggan, Dr. John E. Seylar, and our experienced dental team will always care for you as we would a family member: with great professionalism, respect, and integrity. Here, we understand you are unique, with specific oral health goals and concerns. Rather than dictate a specific treatment path, we’ll work with you to determine the best approach for your requirements. This ensures efficient, comfortable care and lasting results you’ll love.

Ours is a dental practice that focuses on you as an individual. We’ve created a welcoming, warm office where you’ll feel at home. From our inviting reception area to our comfortable treatment chairs, we’re attentive and responsive to your needs.

If there is ever anything you need to make a visit easier, whether that’s an appointment time that fits with your busy schedule, questions about a procedure, or a bit of encouragement, please let us know. We want every visit to be positive and for you to smile throughout.


We believe you and your family members deserve advanced dental care. That’s why our doctors and clinical team pursue continuing education. By staying current on new technologies and techniques, we are able to provide the best treatment options for you.

We also believe you deserve customer care that exceeds your expectations. Our front office staff members are always glad to help you with paperwork, will make sure you get the most from your insurance, and ensure that you understand all your treatment and financial options.

In addition, we believe you deserve to understand your oral health and what you can do to keep your mouth healthy. Duggan Dental Group focuses on preventive care, to stop problems from arising, and patient education, too. We’ll teach you about the connection between the health of your mouth and that of your body, the best ways to keep your teeth and gums clean, and nutrition and healthy habits. By educating you, we empower you; we want you to be in control of your body’s and your smile’s health!
