About Us

At Center for Dental Excellence, we believe exceptional dentistry starts with taking the time to know you.

We are a privately owned, relationship-based dental practice in Nashua, NH, built around a simple idea: small with intent. By staying personal and intentional, we can get to know our patients, understand their history and goals, and provide care that feels genuinely tailored to them.

Our practice has been part of the Nashua community since 1989. While the practice has evolved over the years, our commitment to personal relationships, thoughtful care, and doing things well remains at the heart of what we do.

Comprehensive Care for the Whole Picture

Some dental concerns are simple. Others require a more thoughtful, comprehensive approach.

We want Center for Dental Excellence to be the practice patients turn to when they want to understand the bigger picture and address complex dental needs. Rather than looking at each tooth in isolation, we consider your teeth, gums, bite, oral health, goals, and long-term needs when developing your treatment plan.

Our range of care includes comprehensive dentistry, advanced digital dentistry, orthodontics, oral surgery, dental implants, restorative care, and esthetic dentistry, allowing us to coordinate many aspects of your care in one practice.

Small Operations With Intention

At Center for Dental Excellence, we are intentionally a smaller practice.

That means you are not simply another name on a schedule. Our team takes the time to know you, understand what is happening with your dental health, and build a relationship that continues from one visit to the next.

Our practice has cared for patients in Nashua and beyond for more than 10 years, and our team is proud to serve the local community. We want patients to feel comfortable when they walk through our doors and feel like they are part of something bigger than simply going to the dentist.

Experience, Education & Technology

Great dentistry requires continual learning. Our team has completed more than 1,200 hours of continuing education, and Dr. Janiga is a member of the Spear Education Faculty Club.

We also invest in advanced technology that allows us to provide precise, efficient, and comfortable care. From CEREC® same-day crowns and CBCT imaging to in-house dental milling, 3D printing, and digital treatment simulation, technology plays an important role in how we diagnose, plan, and deliver treatment.

But technology is never the point on its own. We use it because it can help us provide better information, more precise treatment, and a more convenient experience for our patients.

Meet Dr. Andy Janiga

Dr. Andy Janiga is committed to providing thoughtful, comprehensive dental care while building lasting relationships with his patients.
Before his career in dentistry, Dr. Janiga served five years in the U.S. Army. His military experience helped shape the discipline, commitment, and sense of responsibility he brings to his work today.

As a practice owner, Dr. Janiga has focused on creating an environment where patients receive the time, attention, and quality of care they deserve. His goal is not simply to complete treatment, but to understand what each patient wants to accomplish and develop a plan that makes sense for them.

A Practice Built on Relationships

We are approachable, friendly, genuine, and local. We are not a corporate practice, and we believe that difference matters.

New patients receive extended appointment time so we can get to know them before beginning their clinical evaluation. For patients with more complex dental needs, we may provide additional time to review findings and discuss treatment options.

We also believe that a comfortable dental experience extends beyond treatment. From pillows and blankets to chilled bottled water and seltzers, we have created an environment where patients can relax and feel at home. Families are welcome, and our youngest patients can enjoy books and toys in the waiting area and choose a prize after their visit.

More Than a Dental Office

Our connection to the community extends beyond our practice. Our team is involved locally through organizations such as the Rotary Club, and we volunteer with the Traveling Tooth Fairies.

We are proud to care for patients throughout Nashua and surrounding communities in New Hampshire and Massachusetts, and strongly value the relationships we have built with local families over the years.

Experience Dentistry Delivered with Purpose

We know we may not be the right practice for everyone. But if you are looking for a dental team that takes the time to listen, approaches complex concerns thoughtfully, invests in advanced education and technology, and genuinely cares about getting things right, we may be exactly what you are looking for.

At Center for Dental Excellence, we believe you should be able to receive comprehensive, high-quality dentistry in a comfortable, relaxed, and enjoyable environment.
