Alexandra Antonopoulou, DDS in Baltimore: Root Canal Specialist for Referred Patients

Alexandra Antonopoulou, DDS operates as an endodontist in Baltimore, treating infections and damage inside the tooth through root canals and related procedures. She accepts referrals from general dentists across the city and surrounding counties and does not typically handle walk-in emergency cases or primary patient acquisition.

What this practice actually is

Endodontics is a specialty branch of dentistry focused on the pulp, the tissue inside the tooth containing nerves and blood vessels. Antonopoulou diagnoses and treats conditions like deep decay, trauma, failed previous root canals, and cracked teeth. Unlike a general dentist, she has completed a two-year graduate residency in endodontics after dental school, allowing her to manage complex cases and use microscopic visualization during treatment. Patients arrive through referral only; their general dentist or another provider sends the case with radiographs and clinical notes.

Services and pricing

Antonopoulou's primary service is endodontic therapy (root canal treatment), which removes infected or inflamed pulp from inside the tooth, disinfects the root canal system, and fills it with an inert material. Prices for root canal treatment typically range from $1,200 to $2,000 depending on tooth location and complexity; anterior (front) teeth are usually less expensive than molars. She also performs retreatment of teeth that have had root canals but have failed, often costing more due to the need to remove previous filling material. Post and core buildup, which provides structural support after root canal therapy, usually costs $300 to $600. Endodontic surgery, used when root canal therapy alone cannot resolve the problem, ranges from $1,500 to $2,500.

Prices vary based on tooth anatomy and the extent of infection or previous treatment. Most dental insurance plans cover endodontic therapy at 50 to 70 percent, with the patient responsible for the remainder and any deductible. Verify current fees and insurance participation directly with the office.

How Antonopoulou compares to other Baltimore endodontists

Baltimore has several endodontic practices, including group practices with multiple specialists and single-provider offices. Larger practices may have multiple treatment rooms and shorter wait times for urgent referrals; solo practitioners often provide more continuity and personalized attention. Some offices in Baltimore offer same-day or next-day scheduling for emergency cases, while others maintain referral-based schedules with lead times of one to three weeks. If your general dentist has an existing referral relationship with Antonopoulou, treatment coordination may be smoother; if you are seeking an endodontist independently, ask your dentist whether they have a preferred provider or can recommend one based on your case.

Who this practice suits and who it does not

Antonopoulou is appropriate for patients with symptomatic tooth pain, failed previous root canals, or complex anatomy identified by their general dentist. She is a suitable referral for someone whose insurance covers endodontics in-network and who can tolerate appointments of 90 minutes to two hours. She does not accept walk-in emergency patients; if you have acute tooth pain, contact your general dentist for an urgent referral or visit an emergency dental clinic. Patients without a referring dentist will need to establish general dental care first or call Antonopoulou's office to ask whether she accepts self-referrals (policies vary).

What the first visit involves

You will arrive with a referral from your dentist, imaging (X-rays or CBCT scans), and your clinical history. Antonopoulou will review the radiographs, perform a clinical examination, and test the tooth with percussion and thermal sensitivity tests to confirm the diagnosis. She will discuss treatment options, expected outcomes, and fees. If you proceed, treatment may begin at that visit or be scheduled for a second appointment depending on the tooth, the severity of infection, and your schedule. Expect to have the tooth numbed, isolated with a rubber dam (a latex sheet that keeps the tooth dry and prevents aspiration of instruments), and treated under magnification. The appointment typically takes 90 to 120 minutes.

Hours, parking, and logistics

Verify current hours and parking options by calling the office directly, as endodontic practices often adjust scheduling based on referral volume. Most endodontists in Baltimore operate Monday through Friday during business hours and do not staff weekend or evening clinics. Street parking, lot parking, or paid garage access depends on the office location; ask your dentist or Antonopoulou's front desk staff when you schedule.

Antonopoulou's role in Baltimore's dental ecosystem is defined by expertise in a narrow, essential specialty. She resolves cases that general dentists identify but cannot safely treat, using advanced imaging and magnification to preserve teeth that might otherwise be extracted.
