Welcome to Great Hill Dental Partners Newton

We know that your comfort and convenience are important to you when it comes to your dental care. We provide a warm, safe and relaxed office atmosphere, along with the highest quality, state-of-the-art dental services.

Formerly Gentle Dental Newton, our location has been providing high-quality dental care from experienced dental professionals for over 5 years in the Newton area. Our team of award-winning dentists and dental professionals, the high level of dental care you receive from our providers, and our commitment to modern investment in technology has remained the same. While our office is changing from a Gentle Dental, we continue to be committed to our mission of healthy confident smiles for life.

We appreciate your selection of our practice for your dental needs, and we are excited to offer even more comprehensive multi-specialty dental care in one location including general dentistry services, orthodontic services, and oral surgery services. By transitioning the office into Great Hill Dental Partners, you will have access to additional doctors, more appointment availability, specialists like oral surgeons, and the newest technology. We are changing our name as we invest more deeply in supporting general dentists with high-quality, full-time specialty care so they can provide the best outcomes for patients in the communities we serve.


Whatever your oral care needs, we will take care of you with an experienced staff that provides both outstanding professional services along with the kindness and respect you deserve. We work hard on your behalf, maximizing your insurance benefits and making your care as affordable as possible.
If you have children in need of dental care, we have an outstanding pediatrics staff available – we love providing care for kids in a friendly, safe and even educational way, reducing their anxiety and making the visit as pleasant as possible for your child.

Our Vision: To eliminate oral disease as source of systemic health risk so that people can live longer, healthier lives.

Our Mission: To provide expert oral health services to patients through coordinated dental specialists and new technologies in a convenient, comfortable, and caring environment.


As a 42 North Dental supported practice we abide by TRUE values: Teamwork, Respect, Urgency, Excellence.
Inherent in these values is our commitment to providing high-quality dental care to patients of all races, religions, gender identities, sexual orientations, abilities, national origins and ethnicities.
