About Amsterdam Dental Group

At 100 South Broad Street, a block below City Hall, Amsterdam Dental Group occupies Suite 2000, an address within walking distance of most Center City offices and a few minutes from City Hall station on both subway lines. The practice dates to 1948 and is built around an unusual specialty: periodontal prosthesis, a dual training in periodontics and prosthodontics held by very few dentists anywhere. Drs. Harold Baumgarten, Jeffrey Ingber, Howard Fraiman, Caleb Cross, Brian Kasten, Thomas Yoo and Michelle Ordway all teach at Penn Dental Medicine, which shapes how cases get discussed here.

Complex full-mouth reconstruction is what that training equips the office for, the kind of case where gums, bone and bite all need attention at once rather than one tooth in isolation. A periodontal prosthodontist plans the endpoint first, deciding how the finished teeth should meet, how much tooth should show when you smile and where the gum line ought to sit, then works backwards to determine which teeth are worth saving, where implants go and what grafting is required. Implant work includes All-on-4 same-day full-arch restorations and the practice's minimally invasive MIDI technique. Digital Smile Design and 3D digital impressions let you see a proposed result before anything is prepared, though a digital preview is a plan rather than a promise.

Cosmetic and restorative work runs alongside: porcelain veneers, bonding, crowns, whitening and Invisalign. Routine periodontal care is in-house as well, from scaling and root planing through gum surgery and tissue grafting, so a patient whose gums need stabilising before restorative work is not sent elsewhere partway through a plan. The team also treats cleft palate and ectodermal dysplasia and handles reconstruction after oral cancer, which is a genuinely different skill set from routine cosmetic dentistry. Dr. Ordway speaks Spanish, Russian and French.

Veneers are a reasonable answer to worn, chipped or badly discoloured front teeth, but fitting them removes enamel permanently, and whitening will not lighten an existing crown or veneer; the colour of ceramic is fixed when it is made. The Philadelphia office runs 8:30 a.m. to 5:00 p.m. Monday through Thursday and closes at 4:00 p.m. on Friday, with sister offices in Paoli on the Main Line and in Margate at the shore. Parking on this block of Broad Street means a garage rather than the kerb, so budget for it or come by subway.

Founded in 1948 and based at 100 South Broad Street, Suite 2000, a block below City Hall. The team holds dual training in periodontal prosthesis, combining periodontics with prosthodontics, and teaches at Penn Dental Medicine. Work spans complex full-mouth reconstruction, All-on-4 and minimally invasive MIDI implants, porcelain veneers, crowns, bonding, whitening and Invisalign, plus care for cleft palate, ectodermal dysplasia and post-cancer reconstruction. Digital smile design and 3D impressions are used at planning. Spanish, Russian and French spoken.

Frequently Asked Questions

What is periodontal prosthesis and why does it matter for my case?
It is a dual specialisation combining periodontics, which deals with the gums and supporting bone, and prosthodontics, which deals with replacing and rebuilding teeth. Very few dentists hold both. It matters when a mouth needs several things resolved together, such as gum disease alongside worn or failing teeth, missing teeth and a collapsed bite, because one clinician can plan the finished result and the surgical steps as a single sequence instead of stitching together separate opinions.
How accurate is a digital smile preview?
Digital smile design uses photographs, a facial analysis and a 3D scan to model the proposed shape, length and position of your teeth before any preparation begins. It is genuinely useful for agreeing on a direction and for catching a plan you would not have liked. It remains a design rather than a guarantee: gum response, the underlying tooth structure and how ceramic behaves all influence the final result, and small adjustments at the try-in stage are normal.
Would veneers or crowns suit me better?
It depends on how much sound tooth is left. A veneer is a thin ceramic facing bonded to the front of a largely intact tooth after a small reduction of enamel, and it handles discolouration, chips, minor crowding and worn edges well. A crown covers the whole tooth and is the sensible choice when a tooth is heavily filled, cracked or root-treated. Both require irreversible preparation, so the decision belongs at the planning stage.

I went last week to have some dental treatment done and I was very pleased how they took care of me. Starting from the from the front desk staff members who were so attentive and accommodating, continuing with Joan, who is the best I’ve known so far, she was so sweet and made me feel at home. Dr Yoo was very knowledgeable and caring, he addressed my issues in the best way possible. I truly loved my experience at Amsterdam Dental Group. I highly recommend to anyone.

This was my first visit as a new patient. I was impressed with your practice just based on what I could see from the website and other online reviews, and I'm pleased to say it lived up to my expectations. Very well organized and clean office, and Dr. Cross is a pleasant fellow who did a very thorough initial exam. Gail and the rest of the office staff were very nice as well. Happy I made the choice to switch and looking forward to many years of great dental care.
