Saving a Tooth from the Inside Out
When decay or an injury reaches deep enough into a tooth, it can infect the soft tissue inside, called the pulp, which contains the nerves and blood vessels that kept the tooth alive as it developed. Left untreated, that infection can spread, cause an abscess, and eventually cost the tooth entirely. Root canal therapy removes the infected tissue, cleans out the inside of the tooth, and seals it, allowing the tooth to stay in the mouth and function normally for years afterward. At Belmont Dentistry in Scottsdale, the goal is always to save a natural tooth whenever it is realistically possible rather than moving straight to extraction.
Signs a Tooth May Need Root Canal Therapy
A few warning signs tend to show up when the pulp inside a tooth becomes infected or inflamed, and catching them early can make treatment more straightforward.
- Persistent or throbbing tooth pain that does not go away on its own
- Sensitivity to hot or cold that lingers well after the food or drink is gone
- Swelling or tenderness in the gums near a specific tooth
- A tooth that has darkened or changed color
- A small, pimple-like bump on the gum near the tooth
Who Is a Candidate for Root Canal Therapy?
Root canal therapy is recommended when the pulp, or inner nerve tissue, of a tooth becomes infected or damaged. Patients with deep cavities, cracks, trauma, or previous dental work that has affected the tooth may benefit from this treatment. The goal of a root canal is to remove the source of the problem while preserving the remaining healthy tooth structure.
During an evaluation at Belmont Dentistry, the condition of the tooth, surrounding tissues, and overall oral health are reviewed before recommending treatment. In some cases, a tooth may be too damaged to restore with a root canal. If that happens, other options can be discussed to protect your oral health.
The Root Canal Procedure Step by Step
A root canal is typically completed in one to two visits, and modern numbing techniques make the appointment far more comfortable than its reputation suggests.
Numbing the Area – Local anesthetic is carefully applied to numb the tooth, the surrounding gum tissue and the root area completely, so no discomfort is felt once treatment begins.
Placing a Dental Dam – A small protective sheet is placed around the tooth to keep the area clean, dry, and free of saliva throughout the procedure, which also supports proper healing afterward.
Accessing the Pulp Chamber – A small, precise opening is made through the top of the tooth to reach the infected or inflamed pulp tissue inside the chamber and the root canals below it.
Removing Infected Tissue – Using fine instruments, the damaged or infected pulp is carefully removed from the chamber and each root canal, eliminating the source of the infection.
Cleaning and Shaping the Canals – Each canal is thoroughly cleaned, disinfected, and shaped with specialized tools to remove remaining bacteria and prepare it to hold a lasting filling material.
Filling and Sealing the Tooth – The cleaned canals are filled with a biocompatible material to prevent reinfection, and the access opening is sealed with a temporary or permanent filling to protect the tooth going forward.
Placing a Crown After Treatment
Most teeth that receive root canal therapy also need a crown afterward, since removing the pulp can leave a tooth more brittle and prone to cracking under everyday biting force. The crown is typically placed at a follow-up visit once any initial healing has settled, and it restores full chewing strength while protecting the tooth for the long term. Front teeth with smaller fillings sometimes do not require a crown, so this is discussed on a case-by-case basis.
Caring for a Tooth After Root Canal Treatment
After root canal therapy, maintaining good oral hygiene helps protect the restored tooth and surrounding teeth. Most patients can return to normal routines soon after treatment, though the tooth may feel sensitive for a short period.
Helpful habits include:
- Brush and floss daily around the treated tooth
- Avoid chewing extremely hard foods until the final restoration is placed
- Keep regular dental exams and cleanings
- Follow any restoration recommendations provided after treatment

Frequently Asked Questions
About Root Canal Therapy
The procedure itself is performed under local anesthetic, so patients do not feel pain during treatment. At Belmont Dentistry, most people describe it as feeling similar to getting a filling.
Most root canals take about sixty to ninety minutes, though this can vary depending on the tooth and how many canals it has. Some cases are completed in a single visit while others are split across two appointments.
A root canal removes the infected tissue while keeping the natural tooth in place, while an extraction removes the entire tooth. Saving the natural tooth is generally preferred whenever it is a realistic option.
Most back teeth need a crown afterward for added strength, since the tooth can become more brittle once the pulp is removed. This is evaluated individually based on how much of the natural tooth structure remains.
Many root canal-treated teeth last a lifetime with a properly fitted crown and consistent care. Patients in Scottsdale are encouraged to keep up with regular checkups so any issues around the tooth are caught early.
The infection can spread further into the jawbone, potentially forming a painful abscess and increasing the chances that the tooth cannot be saved at all. Treating it promptly generally means a simpler procedure and a better outcome.
It is best to wait until the numbness fully wears off before eating to avoid accidentally biting the cheek or tongue. Softer foods are recommended for the first day or two while the area settles.
Many dental insurance plans cover at least a portion of root canal therapy, since it is considered a standard restorative procedure. Our front office at Belmont Dentistry can help verify your specific benefits before treatment begins.
