Hello, I'm Dr. Xiaoyan Dai, and I'd like to take a moment to share a bit about my journey and commitment to providing top-notch dental care. It's not just my profession; it's my passion.

I graduated from The Dental School of the University of Pennsylvania with a Doctor of Dental Medicine (DMD) degree back in 1998. That was just the beginning of my dedication to the field of dentistry. After completing dental school, I embarked on an incredible journey of learning, investing over 1,000 hours in continuous education to hone my clinical skills and enhance patient care.

Throughout my career, I've focused my studies on Cosmetic Dentistry and Implant Dentistry. These areas of expertise have allowed me to help numerous patients achieve not only beautiful smiles but also improved oral health. I believe that a confident smile can positively impact one's life, and I'm grateful to have played a role in transforming smiles.

​

​

I genuinely care about my patients' needs, and I make it a point to listen to their concerns.
