About Us

Our Story

The story of Hesed Dental began with a simple but meaningful idea: “hesed,” a Hebrew word representing grace, compassion, and loving kindness. Inspired by the beauty of nature, we bring empathy, expertise, and excellence to every smile we create.

Located in Bergen County, New Jersey, Hesed Dental combines advanced dental care with artistry and craftsmanship to restore radiant smiles and uplift the human spirit. This harmony of nature, art, and dentistry defines the essence of Hesed Cosmetic Dentistry—and our story continues with every patient we serve.

Leading the Way in Dental Innovation

At Hesed Dental, we take pride in leading the future of dentistry. Our unwavering commitment to innovation means you’ll receive care that reflects the most advanced techniques and technology available. Our cosmetic dentistry services in New Jersey embody this philosophy. We believe that your dental journey should not only enhance your oral health but also contribute to your overall quality of life — elevating both aesthetics and well-being with every step.

Crafting Perfection in Our Onsite Lab

One of the cornerstones of our practice is our onsite dental lab, which offers a trifecta of benefits: quality, convenience, and consistency. There’s no need to wait for external labs to process your Hesed veneers or crowns. Our in-house lab ensures the prompt delivery of your final restorations, along with any needed adjustments or repairs. This level of reliability allows our prosthodontists to consistently deliver exceptional results tailored to your unique needs.

Artistry and Nature Unveiled

Hesed Dental is more than just a clinic — it is a space where artistry meets the beauty of nature. Through detailed dental photography, sculptural elements, and rich textures, we pay tribute to the elegance and wonder of the natural world. Our mission is to replicate that beauty as closely and authentically as possible, ensuring your smile stays uniquely yours. This devotion to authenticity elevates our care into a refined, luxurious experience that leaves a lasting impression.

Dr. Jason Kwak, DMD, MDS

Dr. Jason Kwak is a prosthodontist specializing in full-mouth reconstruction, comprehensive restorative, implant, and cosmetic dentistry. He believes every successful restoration begins with a thorough understanding of the patient -not only their teeth, but also their oral health, function, esthetic goals, and long-term prognosis. Whether restoring a single tooth or rehabilitating an entire dentition, his philosophy is to provide treatment that is carefully planned, individualized, and designed for predictable outcome.

Dr. Kwak earned his Doctor of Dental Medicine (DMD) degree with honors from the University of Pittsburgh School of Dental Medicine, where he received the Hanau Best of the Best Prosthodontics Award in recognition of exceptional achievement in prosthodontics. He continued his education at the University of Pittsburgh to complete 3 additional years of specialty training in Prosthodontics, earning both a Certificate in Advanced Prosthodontics and a Master of Dental Science (MDS) degree.

Lastly, he completed the Resnik Institute Implant Surgical and Prosthetic Fellowship, receiving advanced training in comprehensive implant treatment planning, implant surgery, and prosthetic rehabilitation.

A unique aspect of Dr. Kwak’s professional background is his experience as both a dental laboratory technician and a prosthodontist. This combination allows him to approach every case from both the clinical and laboratory perspectives, with the final restoration in mind from the very beginning. He integrates diagnosis and treatment planning with an understanding of the artistry, craftsmanship, and scientific principles behind fabricating dental restorations. Dr. Kwak believes every restoration should be thoughtfully designed, planned with a purpose, and individually tailored to each patient’s unique goals and needs. His goal is not simply to replace teeth, but to create restorations that blend seamlessly with each patient’s teeth, function harmoniously, and provide predictable, long-term success.

Outside the office, Dr. Kwak enjoys spending time with his wife, Jenn, listening to music, and spending quality time with family and friends.
