Welcome
Seacoast Prosthodontics
Seacoast Prosthodontics is a specialist dental practice on Griffin Road in Portsmouth, New Hampshire. Dr. Randi completed dental school followed by specialty training beyond general dentistry.
That extra training is what sets a prosthodontist apart from a general Portsmouth NH dentist. Prosthodontists focus specifically on rebuilding and replacing teeth, from a single crown to a full-mouth reconstruction.
Learn more about Dr. Randi's background and training.
Specialist-Level Implant Solutions for Complex Cases
Complex implant cases need careful planning. Dr. Randi uses digital impressions, 3D CT scanning, and computer-guided implant planning to map out treatment before any work begins, supporting precise, predictable outcomes for patients missing several teeth or a full arch.
Explore our full range of dental implant options to see which approach may fit your needs.
All-on-X Full-Arch Restoration
All-on-X uses four strategically placed implants to support a full arch of replacement teeth, designed for patients missing most or all of their teeth in one jaw who want a fixed, non-removable option.
Cosmetic Dentistry
Cosmetic dentistry covers treatments that improve how your teeth and smile look. That can mean closing small gaps, fixing a chipped tooth, whitening stains, or reshaping teeth that are worn down.
Restorative & Cosmetic Care Built Around
Your Smile
Beyond implants, our restorative and cosmetic dentistry services cover a wide range of tooth repair and smile design options. Every treatment plan starts with how your bite and jaw work together, not just how one tooth looks.
