Endodontic Treatment

When a tooth is infected, injured, or causing pain that is hard to explain, it deserves the care of a specialist. Endodontic treatment focuses on the inside of the tooth, the pulp and root canals, with one goal: relieving your pain while saving your natural tooth whenever possible.

At Gainesville Dental Associates, endodontic care is provided by Dr. Nicholas Leon-Guerrero, whose practice focuses on endodontics. Patients get specialist-level treatment for complex cases without leaving the office they already know and trust. Call (703) 754-7151 to schedule an endodontic consultation.

What Is an Endodontist?

An endodontist is a dentist who completes two or more years of advanced training after dental school, focused on diagnosing tooth pain and treating diseases and injuries of the dental pulp. Because endodontists dedicate their practice to this work, they are especially experienced in difficult root canal anatomy, retreatment, and endodontic surgery.

Why See an Endodontic Specialist?

• Expertise with complex cases. Curved, narrow, calcified, or extra canals call for specialized skill and experience.
• Precise diagnosis. Digital X-rays and 3D imaging reveal hidden canals, cracks, and infections that standard images can miss.
• A better chance of saving your tooth. Specialist care can rescue teeth that might otherwise need to be removed.
• Comfort-focused treatment. Endodontists are experts in numbing and in treating teeth efficiently.
• Seamless coordination. Our endodontist, general dentists, and specialist team share records and plan your care together.

Endodontic Services We Provide

Root Canal Therapy for Complex Cases

Most root canals are straightforward, but some teeth have anatomy that makes treatment more challenging, such as molars with extra canals or canals that are narrowed by age or previous dental work. Our endodontist carefully locates, cleans, and seals every canal to give the tooth its best chance of long-term success.

Root Canal Retreatment

Occasionally, a tooth that has had a root canal does not heal as expected, or a new problem develops months or years later. Retreatment removes the old filling material, disinfects the canals again, treats any canals that were missed, and reseals the tooth.

Endodontic Surgery (Apicoectomy)

If infection persists at the tip of a root after a root canal, an apicoectomy may save the tooth. The endodontist removes the infected tissue and the very end of the root, then places a small filling to seal it. The procedure is performed under local anesthesia.

Cracked Tooth Diagnosis and Treatment

Cracked teeth can cause sharp pain when biting or sensitivity to temperature that comes and goes. Early diagnosis is critical. Depending on the crack, treatment may include a dental crown, a root canal and crown, or, if the tooth cannot be saved, an extraction.

Treatment for Dental Injuries

Knocked-out, loose, pushed-in, or broken teeth may damage the pulp, sometimes without immediate symptoms. Our endodontist evaluates and treats injured teeth to protect them and monitors them over time. If you have a dental injury, call us right away or visit our emergency dentist page for first aid steps. Our kids dentistry team also helps care for young patients with injured teeth.

Diagnosing Unexplained Tooth Pain

Tooth pain is not always easy to trace. Pain can be referred from one tooth to another, or even from the sinuses or jaw. Our endodontist uses careful testing and imaging to find the true source of your discomfort before recommending treatment.

Signs You May Need Endodontic Care

• Lingering sensitivity to hot or cold
• Pain when chewing or touching the tooth
• Swelling or a pimple-like bump on the gums
• A tooth that has darkened in color
• Pain or swelling in a tooth that already had a root canal
• A recent injury to a tooth, even if it does not hurt yet

What to Expect During Treatment

1. Consultation and testing. We review your symptoms and dental history, test the tooth, and take detailed images.
2. Clear explanation. Your endodontist explains the diagnosis, your options, and the expected outcome before any treatment begins.
3. Comfortable treatment. The tooth is thoroughly numbed, and treatment is completed in one or more visits depending on complexity.
4. Final restoration. After endodontic treatment, the tooth is protected with a permanent filling or a crown, often placed by your general dentist in the same office.
5. Follow-up. We check healing at future visits to make sure the tooth remains healthy.

When a Tooth Cannot Be Saved

Although our goal is always to preserve your natural tooth, some teeth are too damaged to treat. In that case, our oral surgeon can remove the tooth comfortably, and we can replace it with a dental implant. If gum disease is also affecting the tooth, our periodontal team can help create a healthy foundation.

Cost of Endodontic Treatment

The cost of endodontic care depends on the tooth, the complexity of the case, and the type of treatment. Most dental insurance plans cover a portion of endodontic procedures. We provide a clear estimate before treatment and offer flexible financing options, including CareCredit.

Specialist Care Without the Referral Runaround

Gainesville Dental Associates is led by owner and lead dentist Dr. Theo Batistas, supported by a team of experienced general dentists and specialists. Our endodontist, oral surgeon, periodontist, and general dentists work side by side, so your care is coordinated from diagnosis through final restoration.

Endodontic Treatment FAQs

What is the difference between a dentist and an endodontist?

All endodontists are dentists, but an endodontist completes two or more additional years of advanced training focused on diagnosing tooth pain and treating the inside of the tooth. Endodontists perform root canals every day and are especially skilled with complex and difficult cases.

When should I see an endodontist instead of my general dentist?

Your dentist may recommend an endodontist for teeth with curved, narrow, or calcified canals, a tooth that has already had a root canal and is causing problems again, a cracked tooth, a dental injury, or tooth pain that is hard to pinpoint.

What is root canal retreatment?

Retreatment is a second root canal on a tooth that did not heal as expected or developed a new problem. The endodontist removes the old filling material, cleans and disinfects the canals again, looks for any missed or hidden canals, and reseals the tooth.

What is an apicoectomy?

An apicoectomy is a minor surgical procedure that removes the very tip of a tooth root along with any infected tissue around it, then seals the end of the root. It may be recommended when inflammation or infection persists after a root canal and retreatment is not the best option.

Can a cracked tooth be saved?

Often, yes, especially when it is treated early. Depending on where the crack is and how far it extends, a cracked tooth may be saved with a crown, a root canal and crown, or both. A crack that extends below the gum line or splits the root may require extraction.

Is endodontic treatment painful?

Modern endodontic treatment is performed with local anesthesia and is typically no more uncomfortable than getting a filling. Most patients feel relief from their tooth pain once treatment is complete, with only mild tenderness for a few days.

Is saving my tooth better than getting an implant?

When a tooth can be saved, keeping it is usually the best choice. Your natural tooth looks, feels, and functions better than any replacement, and saving it often costs less and takes less time than an extraction followed by an implant.
