Welcome to River Valley Periodontics & Implant Dentistry

Experience You Can Trust for Comprehensive Periodontal Care

Since 1974, River Valley Periodontics & Implant Dentistry has been dedicated to providing the highest quality treatment, using the latest technologies, in a friendly and caring atmosphere. That philosophy is the foundation of everything we do.

We are the longest-operating periodontal practice in our area, and we have six convenient offices, including five in Connecticut:

  • Madison
  • Norwich
  • Old Saybrook
  • Waterford

and one in Rhode Island:

  • Westerly

No other periodontal and dental implant practice in our area has the depth and breadth of experience we do. Our talented team of doctors includes periodontal specialists whose expertise and use of the latest advancements in dentistry enable our patients to receive top-notch gum care and dental implant treatment. Our goal is to be the standard for periodontal and dental implant expertise in Southeastern Connecticut and the Southwestern Rhode Island area.

Comfortable and Personable Care

In each of our offices, we put the patient first in all circumstances. We work to educate each patient regarding the conditions affecting their oral health and provide clear, effective and attainable plans to improve it. We do this in a comfortable environment while collaborating with the patient’s referring dentist. We cater to the needs of each patient individually and enjoy what we do. We truly work together as a family, and that camaraderie is evident in the care we provide—patients are always treated like a part of our River Valley Perio family.

Our team believes in providing the most pleasant care possible, and we offer a range of comfort amenities and sedation options so each patient can receive their care in a way that makes them feel comfortable. We make sure to communicate well with each patient, and their referring dentist, to ensure their dental treatment is delivered in a consistent, predictable and efficient manner.
