What We Do
Access Endodontics provides specialty endodontic care for patients who need an endodontist in Ellicott City, MD. Led by Dr. Lina Jarboe, our team focuses on diagnosing complex tooth pain, providing root canal-related care, and treating dental trauma. Dental operating microscopes and 3D CBCT imaging help us examine the tooth in detail, while laser-assisted disinfection supports thorough cleaning during appropriate procedures. We serve patients from Ellicott City, Columbia, and throughout Howard County.
Many patients come to us through a referral from their general dentist, while others reach out because of ongoing tooth pain, sensitivity, or an injury. We take time to explain our findings, answer questions, and discuss recommended care before treatment begins. Our approach emphasizes patient comfort, appropriate treatment, and preserving the natural tooth whenever possible.
Services

Root canal therapy
We are highly skilled in painlessly removing infected pulp, disinfecting, and protecting the tooth from further complications.

Root canal retreatment
A previously treated tooth may need additional care if symptoms continue or a new problem develops. Retreatment reopens, cleans, and reseals the tooth to address those concerns.

Endodontic Retreatment
If a root canal fails and pain or other issues persist, this procedure can help save your tooth.

Cracked Teeth
& Traumatic Injuries
We strive to save injured teeth that might have been damaged in an accident or while playing sports.

Laser-Assisted Irrigation and Disinfection
This cutting-edge technique reduces discomfort, and with precision, significantly reduces the bacterial counts within the canal.

Apicoectomy
We can remove damaged tooth root tips and tissue through this minimally invasive surgical procedure.

Pulp regeneration
Pulp regeneration may support continued development in certain immature teeth with damaged or infected pulp. Whether it is appropriate depends on the tooth and clinical evaluation.

Internal bleaching
Internal bleaching may address discoloration from inside a previously injured or treated tooth. It is a targeted endodontic service rather than general cosmetic tooth whitening.
When to see an endodontist
Many patients visit an endodontist after their general dentist identifies a problem that requires specialized care. However, you may also contact the office when ongoing symptoms suggest that the inside of a tooth could be damaged or infected.
Persistent or severe tooth pain deserves an evaluation. Don’t ignore severe tooth pain, swelling, or an injured tooth. Talk with your dentist or contact Access Endodontics at 410.304.7226 to discuss appointment availability.
Signs that it may be time for an endodontic evaluation include:
- Pain that lingers after something hot or cold: Lingering temperature sensitivity can be a sign that the pulp inside the tooth is inflamed or damaged and needs evaluation.
- A tooth that still hurts after a previous root canal: Pain, sensitivity, or swelling that develops or returns after prior treatment may mean the tooth needs another endodontic evaluation.
- Swelling, tenderness, or a bump on the gum near a tooth: These changes can point to inflammation or infection around the root and should be evaluated.
- A cracked, chipped, or knocked-out tooth: Dental trauma can damage the pulp or supporting tissues, even when the full extent of the injury isn’t immediately visible.
- A tooth that has darkened after an injury: A tooth that changes color after trauma may have damage inside the tooth and should be evaluated for appropriate care.
- Pain that your general dentist cannot pinpoint: Endodontists use specialty training, imaging, and magnification to help identify the source of complex or unexplained tooth pain before recommending treatment.

What Patients Are Saying
Frequently asked questions
An endodontist is a dentist with additional specialty training in diagnosing tooth pain, treating dental injuries, and treating the dental pulp and tissues around tooth roots. Endodontists focus on procedures such as root canal therapy, retreatment, and endodontic surgery.
Your dentist may refer you to an endodontist when a tooth problem needs specialized diagnosis or treatment. Access Endodontics works with referring dentists to evaluate complex pain, prior root canal concerns, or injuries, and to discuss findings and treatment recommendations before care moves forward.
During root canal therapy at Access Endodontics, the endodontist removes inflamed or infected tissue from inside the tooth, cleans and disinfects the canal system, and seals the space. The goal is to address the source of the problem and preserve the natural tooth when appropriate.
Local anesthesia is used to numb the area during root canal therapy, so treatment is intended to be comfortable. Some patients may notice pressure during the procedure or temporary tenderness afterward, and experiences vary. Access Endodontics can explain what to expect based on the tooth and the planned treatment.
If you have severe tooth pain or a cracked, chipped, dislodged, or knocked-out tooth, contact your general dentist or Access Endodontics promptly at 410.304.7226. The team can discuss whether an endodontic evaluation is appropriate. If swelling affects breathing or swallowing, or symptoms suggest a medical emergency, seek emergency medical care.
Whether you need a crown after a root canal depends on the tooth and the restoration your dentist recommends. Your endodontist and general dentist can coordinate the next step after treatment based on your individual needs rather than assuming every treated tooth requires the same restoration.
