Root Canals

Root Canal Treatment for Saving Your Tooth, Ending the Pain

Tooth pain that doesn’t let up, especially when you bite down, or when something hot or cold sets it off, is your mouth’s way of telling you something is wrong inside the tooth. Most of the time, that something is an infection in the pulp, and a root canal is the most effective way to deal with it while keeping your natural tooth intact.

At Scottsdale Family Dentistry, we perform root canal treatment for patients throughout Scottsdale, Tempe, Mesa, and Phoenix. Our approach is straightforward: thorough treatment, proper anesthesia, and a clear plan for restoring the tooth afterward so it functions normally for years to come.

What’s Actually Happening When a Tooth Gets Infected

Inside every tooth, beneath the hard enamel and dentin, is a soft tissue called the pulp. It contains nerves and blood vessels, important during tooth development, but not essential to a fully formed adult tooth’s survival.

When bacteria reach the pulp, through a deep cavity, a crack, or trauma, infection sets in. The pulp becomes inflamed and begins to break down. Because the pulp is enclosed inside a rigid tooth structure with nowhere to swell, the pressure builds, and the pain can become severe.

Left untreated, the infection spreads beyond the tooth into the surrounding bone and tissue, forming an abscess. At that point the situation becomes considerably more serious and complex to treat.

A root canal stops that progression. The infected pulp is removed, the inside of the tooth is thoroughly cleaned and disinfected, and the space is filled and sealed. The tooth stays in place, and with a crown placed afterward, it can function normally for decades.

Symptoms That Suggest You May Need a Root Canal

Not every tooth infection causes dramatic pain. Some signs are obvious; others develop gradually:

• Persistent, throbbing toothache, especially when chewing or applying pressure
• Sharp sensitivity to heat or cold that lingers well after the source is removed
• Pain that seems to radiate toward the jaw, ear, or surrounding teeth
• A tooth that has darkened noticeably compared to its neighbors
• Swelling in the gum near a specific tooth
• A pimple-like bump on the gum that may drain periodically
• Persistent bad taste or bad breath that isn’t resolved by brushing
• A tooth that previously had a large filling and has started hurting again

If you’re experiencing any combination of these, don’t wait to see if it resolves on its own. Dental infections don’t heal without treatment, and the earlier we catch them, the simpler the procedure.

Types of Root Canal Treatment

Standard root canal treats infection in a single-rooted tooth such as a front tooth or premolar. It’s typically completed in one appointment and is the most straightforward version of the procedure.

Multi-canal root canal treats molars, which have two or three roots and multiple canals to clean and fill. The procedure takes longer due to the additional anatomy involved but follows the same principles.

Root canal retreatment is performed when a tooth that was treated previously develops a recurrence of infection. This can happen years later if bacteria re-enter the tooth through a failed seal, a new cavity, or a crack. Retreatment cleans out the old filling material and re-treats the canals. It’s more complex than an initial treatment but is often successful in extending the life of the tooth.

Emergency root canal is for situations where pain or swelling is severe and requires prompt attention. If you’re in that situation, call us, we prioritize urgent cases.

The Procedure, Clearly Explained

The thing most patients tell us after a root canal is that it was nothing like they feared. The reputation for pain largely comes from the days before modern anesthesia and technique. Today, a root canal feels much like having a filling placed.

Anesthesia: The area is numbed with local anesthetic before anything begins. We wait until the tooth is completely numb. You may feel pressure and some vibration during the procedure, but you should not feel pain.

Access and cleaning: A small opening is made in the top of the tooth. Tiny instruments are used to remove the infected pulp and clean the length of each canal. The canals are shaped and disinfected thoroughly.

Filling and sealing: The cleaned canals are filled with a rubber-like material called gutta-percha and sealed with dental cement to prevent re-infection.

Restoration: A temporary or permanent filling closes the access opening. In most cases — particularly for back teeth, a dental crown is placed afterward to protect and strengthen the tooth, which becomes more brittle after the pulp is removed.

Most root canals are completed in one to two appointments. You may experience some tenderness for a few days afterward, but it typically resolves quickly.

Root Canal Cost in Scottsdale

The cost of root canal treatment depends on which tooth is involved (front teeth are simpler and less expensive than molars), whether it’s a first-time treatment or retreatment, and what restoration is placed afterward. We provide a full cost breakdown before treatment begins and can discuss payment options if needed.

Compared to the alternative, extraction followed by an implant or bridge, root canal treatment is almost always the more cost-effective choice, and it preserves your natural tooth, which is always preferable.

Frequently Asked Questions

Does a root canal hurt?
The procedure itself shouldn’t. The infection causes the pain you’re feeling now, the root canal removes it. With proper anesthesia, most patients are surprised by how comfortable the appointment actually is.

How do I know if I need a root canal or just a filling?
A filling addresses surface decay. A root canal is needed when infection or inflammation has reached the pulp. X-rays and an examination can usually distinguish between the two clearly.

What happens if I don’t get treatment?
The infection won’t resolve on its own. It will spread, into the bone, into adjacent teeth, and in more serious cases, into surrounding tissue. Eventually the tooth will need to be extracted. Treating it early is always the simpler and less costly path.

Do I always need a crown after a root canal?
For back teeth, yes, almost universally. The tooth becomes more brittle after treatment and is vulnerable to fracture without a crown protecting it. Front teeth sometimes can be restored with a filling alone depending on how much structure remains.

How long does a treated tooth last?
With a proper crown and good oral hygiene, a root canal-treated tooth can last just as long as any other tooth, decades, sometimes a lifetime.
