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.

Dr. Schulman not only replaced five crowns, she remolded them and added a veneer to give me a full, even smile. The process was well planned, the cost reasonable and the results are truly amazing. I wish I had done this years ago! Lisa and her team are very attentive, knowledgeable and personable… and they are superb at easing anxiety!! I highly recommend Seacoast Dream Dentistry for any services you made need.

Thank you so much to Dr. Schulman for years of great service. I have a bridge that needed to replaced after 20 years and she did an incredible job. She is extremely particular and made sure it was exactly what I wanted. Highly recommend for all complex dentistry cases and I really appreciate how hard they work to get the job done right!

Dr. Schulman is an excellent dentist - my whole family has been very pleased with her work and that of her staff. My adult 29 year-old son, my husband, my 89 year-old mother, and I have all presented with various issues, some quite complex, and she has managed all of them perfectly. We are very happy with Dr. Schulman and are happy to recommend her and Seacoast Dream Dentistry.

I had a crown done by Dr. Schulman, and couldn't be more pleased with the result. Almost as soon as my crown was installed, the pain that I had been "soldiering through" went away. I wish I had done it sooner. My new tooth is an exact replica of my old one, minus the giant crack, and I'm happy to say it is in daily, pain free use
