Root Canals
At Princeton Dental, root canal treatment is a highly effective procedure used to save teeth that would otherwise need to be removed. While the term “root canal” often causes concern, modern techniques make this treatment comfortable, predictable, and essential for protecting both oral and overall health.
When infection reaches the inner portion of a tooth, prompt treatment is critical. Root canal therapy removes the source of infection, relieves pain, and allows the natural tooth to remain in place—helping preserve bite function and smile appearance.
Why Root Canal Treatment Is Sometimes Necessary
Inside every tooth is soft tissue called pulp, which contains nerves and blood vessels. When a tooth is cracked, fractured, or affected by deep decay, bacteria can enter this pulp tissue and cause infection.
If infected tissue is not removed, pressure can build inside the tooth, leading to pain, swelling, and the formation of an abscess. Infections can also spread beyond the tooth, potentially affecting the jawbone and surrounding tissues.
Root canal treatment addresses the infection at its source, preventing further damage and protecting overall health.
Signs You May Need a Root Canal
Some patients experience clear symptoms, while others may have little discomfort until the infection progresses. Common signs that root canal therapy may be needed include:
- Persistent tooth pain or pressure
- Sensitivity to hot or cold that lingers
- Swelling or tenderness in the gums
- Darkening or discoloration of the tooth
- A pimple-like bump on the gums
Early diagnosis allows treatment to be completed before the infection becomes more severe.
What Happens During Root Canal Treatment?
Root canal treatment typically requires one to three visits, depending on the complexity of the tooth and the extent of infection. During the procedure, the infected pulp tissue is carefully removed from the inside of the tooth.
Once the affected tissue is removed, the interior of the tooth is thoroughly cleaned and disinfected. The space is then sealed to prevent bacteria from re-entering and causing reinfection.
Finally, the tooth is restored with a filling or other restoration to return strength and function.
Root Canal Treatment vs. Tooth Extraction
In the past, infected teeth were often removed. Today, root canal treatment allows many of those teeth to be saved. Preserving your natural tooth helps maintain proper bite alignment and prevents neighboring teeth from shifting.
When possible, saving the natural tooth is typically preferred over tooth extraction. Removing a tooth often leads to additional treatment, such as bridges, dentures, or implant restoration, to replace the missing tooth.
Is Root Canal Treatment Painful?
One of the most common misconceptions about root canals is that they are painful. In reality, the procedure is designed to relieve pain, not cause it. Modern anesthetics and techniques allow treatment to be performed comfortably.
Most patients report that root canal treatment feels similar to receiving a routine filling. Any discomfort experienced afterward is typically mild and temporary.
Why a Crown Is Often Recommended After a Root Canal
After root canal treatment, the tooth is no longer nourished by living pulp tissue and can become more brittle over time. For teeth with extensive decay or structural damage, placing a dental crown is often recommended.
A crown protects the treated tooth from fracture, restores strength, and allows it to function normally during chewing. In many cases, the crown is what allows the restored tooth to last for many years—or even a lifetime.
Root Canal Treatment and Long-Term Oral Health
Successfully treated teeth can continue to function just like natural teeth when cared for properly. Routine brushing, flossing, and regular dental visits are essential for maintaining the health of treated teeth.
Root canal therapy also helps prevent the spread of infection, reducing the risk of complications that could affect surrounding teeth or lead to conditions such as gum disease.
When Root Canal Treatment Is Part of a Larger Care Plan
Root canal treatment is often one step within a broader restorative or preventive plan. For example, teeth that have undergone root canal therapy may later be incorporated into solutions such as bridges or serve as support for future restorations.
As part of comprehensive general dentistry care, we ensure that root canal treatment fits seamlessly into your overall oral health plan.
Is Root Canal Treatment Right for You?
If you have been diagnosed with an infected or severely decayed tooth, root canal therapy may be the best option to preserve your natural tooth and avoid extraction. Every case is unique, and treatment decisions are based on careful evaluation and long-term outcomes.
We take time to explain findings, answer questions, and help patients feel confident about their care.
