Root Canal Therapy — Relieve Pain & Save Your Natural Tooth

Root canal therapy is one of the most effective dental treatments for relieving tooth pain, eliminating infection, and preserving your natural smile. With over 14 million procedures performed each year, it is also one of the most common endodontic treatments available today. Thanks to modern techniques and anesthetics, the procedure is virtually painless and far more comfortable than most patients expect.

At One Endodontics, our board-certified endodontists serve patients throughout Falls Church, Sterling, Gainesville, and Fredericksburg, VA with precise, gentle care tailored to each patient's needs.

Signs You May Need a Root Canal

At the center of every tooth is a soft tissue called the pulp, made up of nerves and blood vessels. When this pulp becomes infected or inflamed due to deep decay, trauma, or repeated dental procedures, it can trigger serious and worsening symptoms that should not be ignored.

Common warning signs include persistent toothache or pain when chewing, sensitivity to hot or cold temperatures, swollen or tender gums, tooth discoloration, and abscess or pus near the affected tooth. If you are experiencing any of these, it is important to seek care promptly. Left untreated, a pulp infection can spread and ultimately lead to tooth loss, making early intervention critical.

How Root Canal Therapy Works

The process begins with X-rays to confirm the extent of the infection, followed by local anesthesia to ensure the procedure is completely pain-free. A small access point is created in the tooth, the infected pulp is carefully removed, and the canals are thoroughly cleaned and sterilized to eliminate bacteria.

Once the infection is cleared, the canals are filled with gutta-percha, a biocompatible material, and sealed with a temporary filling to protect the tooth. Within a few weeks, your restorative dentist will place a permanent crown or filling to restore the tooth's full function and natural appearance. This final restoration step is just as important as the procedure itself and ensures the long-term success of your treatment.

What to Expect After Treatment

Recovery after root canal therapy is typically quick and uneventful for most patients. Some mild soreness or sensitivity in the days following the procedure is completely normal and can be managed easily with over-the-counter pain relievers.

To support healing, avoid chewing on the treated tooth until your permanent restoration is in place, keep up with your daily oral hygiene routine, and make sure to attend your scheduled follow-up appointments. Our team at One Endodontics is always available to address any concerns that come up during your recovery.

Root Canal Therapy Cost and Insurance

The cost of root canal therapy depends on factors like the location of the tooth, the severity of the infection, and the complexity of the procedure. In most cases, it is a significantly more affordable option compared to extracting the tooth and replacing it with an implant or bridge.

One Endodontics accepts most major insurance plans and offers flexible payment options to make sure cost does not become a barrier to receiving the care you need.
