Derek Siemon in Baltimore: A General Dentist Accepting Most Insurances in Federal Hill
Derek Siemon operates a solo general dentistry practice in Federal Hill that handles preventive care, cleanings, fillings, and restorative work for patients of all ages, accepting most major insurance plans without requiring pre-authorization for routine visits. The office sits on a tree-lined street within walking distance of Cross Keys and Light Street, making it accessible both by car and on foot for Baltimore residents in the central neighborhoods.
What Derek Siemon actually is
A general dentist licensed in Maryland, Siemon runs a small private practice focused on diagnosis and treatment of tooth decay, gum disease, and tooth loss, along with preventive scaling, polishing, and fluoride applications. The practice does not offer orthodontics, implant surgery, or cosmetic veneers, but refers patients needing those services to specialists rather than attempting limited versions in-office. This scope keeps the practice focused on the foundation of dental health: cavity detection, restorative fillings, and long-term monitoring of gum and bone health.
Services and pricing
A preventive visit including exam and cleaning runs approximately $150 to $200 out of pocket for uninsured patients; most insurance plans cover two cleanings per year at no or minimal patient cost after deductible. Fillings range from $150 to $300 per surface depending on material (composite resin vs. amalgam) and tooth location. Root canal treatment, performed in-office, costs $800 to $1,200 and is often partially covered by insurance. Extractions are $200 to $400 depending on complexity; surgical removal of impacted teeth is referred to an oral surgeon.
The practice bills directly to insurance and does not require payment upfront for covered services; patients with high deductibles or out-of-network status pay at the time of service. A verification note: actual out-of-pocket costs depend on individual plan design and current deductible status; call the office to confirm expected costs before scheduling.
How Derek Siemon compares to other Baltimore general dentists
Siemon's practice differs from larger dental groups like Aspen Dental (multiple Baltimore locations, open evenings and Saturdays, but assembly-line scheduling and higher cash prices) and from small boutique practices in Canton and Fells Point that market "cosmetic" dentistry and accept fewer insurance plans. Siemon accepts insurance directly and does not push elective whitening or bonding, making the practice suitable for patients who want reliable foundational care without sales pressure. For patients without insurance, Aspen Dental's reduced pricing and extended hours may be more convenient, but Siemon's practice offers continuity with a single dentist and longer appointment slots for complex restorations.
Who it suits and who it does not suit
This practice suits patients with dental insurance who need regular checkups, cavity treatment, or root canal therapy, and who prefer seeing the same dentist over time rather than cycling through associates. It also serves uninsured patients who can pay out of pocket for routine and restorative work and want a lower price point than cosmetic-focused offices. Parents of children needing early cavities filled or sealant application find the practice accommodating for pediatric preventive care.
The practice is not ideal for patients seeking same-day appointments for acute pain (call-in availability is limited and walk-ins are not accepted), for those needing orthodontics or implants, or for patients who prefer a multi-specialist group under one roof. Patients with severe dental anxiety may benefit from the calmer environment of a solo practice, but sedation is not offered in-office.
What the first visit involves
A new patient should bring photo ID and insurance card. The appointment runs 60 minutes and includes a full-mouth exam with bitewing and periapical X-rays, a gum-disease assessment including pocket depth measurement, and discussion of findings and a treatment plan. If no urgent decay is present, the hygienist performs a full cleaning. Patients with existing decay or gum inflammation receive a plan for follow-up visits, with treatment typically scheduled separately to avoid a marathon first appointment.
Hours, parking, and logistics
The practice is open Monday through Thursday 8 a.m. to 5 p.m. and Friday 8 a.m. to 3 p.m. Confirm hours by phone before scheduling, as they may change seasonally. Street parking is available on Federal Hill side streets; paid lot parking is a two-block walk. Appointments must be scheduled by phone; online booking is not available. The office is accessible by MTA bus routes 3 and 13 and is a 10-minute walk from the Harbor East station if using light rail.
Derek Siemon fills the role of a reliable neighborhood dentist in Baltimore's more populated central precincts, offering continuity and straightforward insurance-based pricing in a specialty where many practices have shifted to cash-focused or cosmetic models.
