About Locust Street Periodontics Implant Dentistry

Despite the name, the practice works from Suite 2001 at 1500 Walnut Street, high above the corner of 15th and Walnut in Philadelphia's Center City West, a short walk from the Walnut-Locust station and from most of the downtown dental offices that send patients here. It has been operating since 1978, and the current team of periodontists includes Dr. James Torosian, Dr. Tom Fuji, Dr. Farshid Sanavi and Dr. Merriam Seyedain. This is a referral-based surgical practice: gum disease, implant placement, and the reconstructive work in between. Your general dentist stays in charge of your routine care.

Reconstructive and regenerative periodontal surgery is the centre of gravity. Periodontal disease destroys the bone and ligament that hold a tooth in its socket, and once that support is gone, cleaning alone will not bring it back. Regenerative procedures aim to rebuild some of it: the surgeon lifts the gum, debrides the root surface, places graft material or a biologic in the defect and, where indicated, a barrier membrane so that bone rather than faster-growing soft tissue fills the space. Results depend heavily on the shape of the defect. A contained, walled-in crater responds far better than broad horizontal bone loss, which is why an honest assessment sometimes concludes that the tooth should come out and an implant should go in instead.

Advanced cosmetic periodontal therapy is also part of the caseload, and it mostly means correcting the frame around the teeth rather than the teeth themselves: connective tissue grafting to cover exposed roots after recession, and crown lengthening to even out a gum line that sits too low. On the implant side the full sequence is handled in-house, including sinus lifts and ridge grafting before placement.

Assignment of benefits is accepted on most major plans, including Aetna, Cigna, Delta Dental and United Concordia, though it is worth confirming for your specific policy because surgical coverage differs from routine coverage. The schedule is weekday-only: 8:30 a.m. starts, with the latest finish on Thursday at 5:00 p.m. and earlier closes on Wednesday and Friday. There is no weekend or after-hours cover, so an acute abscess is a case for your general dentist or a hospital.

A referral-based periodontal and implant practice on the twentieth floor at 1500 Walnut Street, Center City West, operating since 1978. Drs. James Torosian, Tom Fuji, Farshid Sanavi and Merriam Seyedain handle reconstructive and regenerative periodontal surgery, cosmetic periodontal therapy including root coverage grafting and crown lengthening, and the full implant sequence with sinus lifts and ridge grafting. Assignment of benefits is accepted on most major plans. Weekday hours only, with no after-hours cover.

Frequently Asked Questions

The practice is called Locust Street, so where is it actually located?
The office is at 1500 Walnut Street, Suite 2001, on the corner of 15th and Walnut in Center City West. The name reflects an older address rather than the current one, and it is a common source of confusion when patients are given directions. From the Walnut-Locust station on the Broad Street Line it is a two-minute walk, and the building has a staffed lobby with lifts to the twentieth floor.
Can gum surgery regrow bone that periodontal disease has destroyed?
Partly, in the right conditions. Regenerative procedures clean the root surface, place graft material or a biologic agent into the bone defect and often cover it with a membrane so bone rather than gum tissue fills the space. Narrow, walled-in defects respond well; broad, flat bone loss largely does not. A periodontist should tell you honestly which type you have, because where regeneration is unlikely, extraction and an implant may give a more predictable long-term result.
Will my insurance cover periodontal surgery here?
The practice accepts assignment of benefits on most major plans, including Aetna, Cigna, Delta Dental and United Concordia. That said, surgical periodontal coverage is usually governed by different limits and waiting periods than routine cleanings, and many plans cap the annual maximum well below the cost of a full course of treatment. Ask the office to submit a pre-treatment estimate to your insurer before you begin, so the out-of-pocket figure is known upfront.

I had a teeth cleaning yesterday with Kayla. She was excellent; very thorough, professional and nice. She explained to me what she saw in the exam. I felt that I was in very good hands. I had total confidence in her skills and knowledge. She was also very gentle.

Tried to establish care. Very rude front desk receptionist who could probably use some coaching on how they speak to new patients. No thanks.

Dr. Seyedain is a kind, thoughtful, and caring dentist who obviously cares deeply about her patients and has the skills and knowledge to ensure that they receive the best treatment possible. I am very careful with my dental health, and she is unfailingly attentive to all my concerns, answering my questions quite thoroughly and patiently. I should add that my high impression of her extends to the other staff there - from the support staff to the dental assistants. Invariably, they are caring and courteous. I cannot recommend them highly enough.

My recent experience at the practice was quite disappointing. They rescheduled my appointments twice due to the hygienist’s unavailability, which I understand happens. However, when I missed an appointment because of a scheduling error, I was taken aback to learn they were going to charge me $180 for it. During my phone call that day, no one mentioned any fees, and I only found out about the charge when I arrived for my rescheduled appointment. I attempted to speak with a manager about this issue, but no one was available, and despite my efforts to follow up, I haven’t received any callbacks. The only positive aspect of my visit was the hygienist, who took the time to listen to my concerns and engage with me. Unfortunately, the manager has yet to reach out as promised and it's been weeks.

I experienced a comprehensive diagnosis of my dental issues clearly explained using X-rays to ensure my understanding. A treatment plan was likewise thoroughly reviewed with me and all my questions answered. I have the utmost confidence in Dr. Torosian and look forward to his rectifying my dental issues. Everyone I encountered at this office was very courteous and competent. The review of my insurance coverage to anticipated coverage was extremely helpful.
