When tooth pain or infection strikes, root canal therapy often provides the solution for relief and long-term oral health. At Duggan Endodontics, we specialize in advanced root canal treatments that save natural teeth, restore function, and prevent the need for extraction. Patients throughout Austin trust our endodontic team for expert care, comfort-focused treatment, and modern technology.
What Is a Root Canal?
A root canal is a treatment designed to remove infected or inflamed pulp tissue from inside a tooth while preserving the tooth itself. The pulp is the soft inner layer that contains nerves and blood vessels. When this tissue becomes infected due to decay, cracks, trauma, or repeated dental work, the tooth cannot heal on its own.
In simple terms, a root canal allows us to:
•
Stop Pain - By removing infected nerves and tissues causing toothaches.
•
Prevent Tooth Loss - Saving your natural tooth instead of extracting it.
•
Restore Function - Allowing you to chew, speak, and smile comfortably again.
Once treated, the tooth is cleaned, sealed, and often restored with a crown for long-lasting strength.
Why You May Need Root Canal Therapy
Root canal therapy is recommended when bacteria have invaded the pulp and caused infection. Without treatment, the infection can spread, leading to tooth loss or even abscesses in the surrounding bone.
Some common reasons include:
•
Deep Tooth Decay - Cavities that extend beyond the enamel and dentin into the pulp.
•
Fractures or Cracks - Even microscopic cracks can allow bacteria inside.
•
Repeated Dental Procedures - Restorations that weaken or expose the pulp over time.
•
Dental Trauma - Accidents or sports injuries that damage the pulp.
•
Large Fillings - Restorations that leave little natural tooth structure for protection.
•
Pulp Calcification - Deposits inside the tooth that become infected.
These conditions make root canal therapy the best option to stop infection and preserve your natural tooth.
What Causes Pulp Infection?
The most common causes of pulp infection include untreated cavities, cracked teeth, multiple dental procedures, or sudden injury. Once bacteria reach the pulp, the body cannot heal the infection without professional treatment. Symptoms often include persistent toothaches, sensitivity to hot or cold, swelling, or tenderness when chewing.
The Root Canal Process
At Duggan Endodontics, we make the root canal process straightforward and comfortable:
1.
We begin with local anesthesia (and sedation if needed) to ensure a pain-free experience.
2.
The infected pulp and bacteria are carefully removed using advanced endodontic tools.
3.
The canals are cleaned, disinfected, and sealed with a safe, biocompatible material.
4.
A temporary or permanent restoration is placed to protect the tooth.
5.
In most cases, a dental crown is recommended to strengthen and restore full function.
With today’s technology, most root canals are completed in one or two visits and provide long-lasting results.

Root Canal Safety
Root canal therapy is one of the safest and most effective dental procedures available today. Performed successfully for over a century, there is no scientific evidence linking root canals to broader health concerns. At Duggan Endodontics, we use advanced sterilization, digital imaging, and precision techniques to ensure predictable, safe outcomes.
Is a Root Canal Painful?
Many patients are surprised to learn that root canals are not painful. In fact, the pain most people associate with root canals actually comes from the infection itself—not the procedure. With modern anesthesia and sedation, the process feels no more uncomfortable than getting a filling. After treatment, mild soreness is normal and can be managed with over-the-counter medications. Learn more about what to expect with pain.
Root Canal Myths vs. Facts
Unfortunately, root canals are surrounded by myths. Let’s set the record straight:
•
Myth: Root canals are extremely painful.
•
Fact: With modern techniques, they are virtually painless.
•
Myth: It’s better to pull a tooth than get a root canal.
•
Fact: Saving your natural tooth is always the healthier and more cost-effective option. See root canal vs extraction.
Treating infected teeth is not new—evidence of early dental treatments dates back thousands of years. Modern root canal therapy, however, has evolved with advanced imaging, microsurgical tools, and biocompatible materials that make the procedure safer and more effective than ever before. Patients today benefit from decades of research and innovation. Learn more about the history of root canals.
Schedule Your Root Canal Appointment in Austin
If you are experiencing persistent tooth pain, sensitivity, or swelling, a root canal may be the solution you need. At Duggan Endodontics, we provide gentle, effective root canal therapy in Austin with advanced technology and personalized care.
Most root canals can be completed in one to two appointments, depending on the tooth’s complexity and the extent of infection. Molars and retreatments may take longer.
How long will my root canal last?
With proper oral hygiene, regular dental checkups, and a protective crown if recommended, root canal-treated teeth can last many years—even a lifetime. Learn more about how long root canals last.
Can I eat normally after a root canal?
You should avoid chewing on the treated tooth until a permanent restoration or crown is placed. Once fully restored, you can eat, chew, and smile normally again. See our root canal aftercare.
What happens if I don’t get a root canal?
Without treatment, the infection will continue to spread, leading to severe pain, abscesses, bone loss, and ultimately tooth loss. A root canal is the best way to save the tooth and stop infection. Learn about what causes pulp infection.
