Happy Patient in Clinic

Treating the whole person, not just the teeth and gums. This philosophy is alive and well in everything we do at the dentist’s office of David A. Goodman, DMD, and Alan C. Ko, DMD, Advanced Cosmetic & Prosthetic Dentistry. This approach to dental care reflects a foundation first set by Dr. Carl DiGregorio in 1975. When Dr. Goodman joined the practice in 1984, he built upon Dr. DiGregorio’s vision to give back to Milford and the wider area of southeastern Massachusetts through dentistry. Today, this legacy lives on in Drs Alan Ko, Brittany Bressler, and Saeed Kashefi.

We start with a fundamental commitment to authentic patient-centered, evidence-based care. From there, we consistently build on this cornerstone of our practice with the latest, safest, clinically proven techniques and technologies available to modern dental professionals. The result is trusted relationships between dentists, staff, and patients. These relationships help to support lasting oral health, which further supports our valued patients’ systemic health and overall quality of life.

Our practice distinguishes itself favorably from other offices with a unique combination of “timeless,” people-centered characteristics and timely, cutting-edge knowledge and tools. Examples of these qualities and services include:

  • Unhurried, routine visits – We set aside a full hour for the initial appointment. So we can get to know more about you. In this way, we can best treat you.
  • Precision, comprehensive dental implants – We use 3-D printing and a 3-D surgical guide to ensure precise placement of implants, which function like tooth roots to stabilize prosthetic teeth (crowns, bridges, dentures).
  • Gum grafting – We support healthy gums with interventions such as gum grafting. We can take tissue from one part of the mouth and transfer it (as a “graft”) to resolve receding gums and achieve a more balanced gum line. 
  • Multi-faceted TMD therapy – Our talented practitioners appreciate that there are many sources of, and potential interventions for, treating temporomandibular joint disorders, from oral appliance therapy to bite correction.
  • Invisalign® — Our team takes a special interest in orthodontic treatment. Notably, Invisalign® presents a discreet and removable way to straighten teeth without silver-colored, fixed metal braces. 
  • Sleep-disordered breathing – We can prevent the serious complications associated with conditions such as obstructive sleep apnea with special oral appliances, such as mandibular advancement devices or the Vivos® method. 
  • Extensive expertise to support pediatric airway health – We emphasize early intervention in childhood with oral appliances, special exercises, and a multi-disciplinary approach. 
  • Cosmetic services – We bring out the natural, beautiful best in your smile with everything from professional teeth whitening (that really works) to stain-resistant porcelain veneers and full-mouth smile makeovers!

Of course, this list only skims the surface of all we offer! To take a deeper dive with us, contact our talented and kind team in Milford, MA, today. Call (508) 850-0686 or conveniently request an appointment from this website. We’ll see you soon!
