Root Canal Treatment | Dentist in West Omaha, NE

Saving a Tooth When Infection Has Reached the Nerve

The pulp inside each tooth contains nerves and blood vessels that keep the tooth healthy during development and provide sensation afterward. When deep decay, a crack, or trauma allows bacteria to reach the pulp, the tissue can become infected, causing severe pain and potentially allowing the infection to spread into the surrounding bone and tissues.

Root canal therapy removes the infected pulp, thoroughly cleans and seals the root canals, and preserves the natural tooth. By saving the tooth instead of extracting it, root canal treatment relieves pain, restores function, and helps maintain the alignment and stability of your bite.

What Is a Root Canal?

A root canal is the natural channel inside each tooth that contains the pulp, made up of nerves and blood vessels. Root canal therapy removes infected or damaged pulp, cleans and disinfects the canals, seals them to prevent reinfection, and restores the tooth. Back teeth are usually protected with a crown after treatment.

Although the treated tooth no longer has nerve tissue, it remains securely anchored in the jaw and functions like a natural tooth. Because it becomes more vulnerable to fracture after treatment, placing a crown is often recommended to strengthen and protect it for long-term use.

Symptoms That Point to an Infected Tooth

Some infected teeth announce themselves unmistakably. Others produce almost nothing, particularly when the pulp has died and the acute pain phase has passed, which is why our dentists find some cases on routine imaging in patients with no complaints at all.

Symptoms worth acting on include:

Severe, persistent or throbbing toothache, often worse when lying down
Pain that lingers well after exposure to hot or cold rather than fading within seconds
Sharp pain when biting down on one specific tooth
Swelling in the gum near a tooth, or a tender bump that may come and go
Swelling in the face, cheek or jaw
A tooth that has darkened noticeably compared with its neighbors
A pimple-like spot on the gum that drains and then returns
A bad taste or odor that keeps coming back from one area
Tenderness in the gum and bone around a particular tooth
A tooth that feels different when you tap it

Certain signs need attention urgently rather than at the next available appointment. Facial swelling, swelling that extends toward the eye or down the neck, fever alongside dental pain, difficulty swallowing or breathing, and pain severe enough to prevent sleep all indicate infection that is spreading. Call our office at 402-991-6965, and if breathing or swallowing is affected, seek emergency medical care.

Inside a Root Canal Appointment

Most root canals are completed in one or two appointments, generally lasting sixty to ninety minutes each depending on which tooth is involved and how many canals it has.

Examination and imaging

Our dentist tests the tooth's response to temperature and pressure and reviews imaging to confirm the diagnosis, see the root anatomy and check for infection in the bone at the root tip. Molars have more canals and more variation than front teeth, so knowing the anatomy in advance matters.

Discussing the plan

You will hear what the treatment involves, how many appointments to expect, whether a crown will be needed afterward, and the cost, including your insurance coverage.

Numbing the tooth

Local anesthetic is administered and tested thoroughly before anything begins. An acutely infected tooth is sometimes harder to numb completely, and our dentist will take the time to get it right rather than proceeding while you can still feel something. Say so if any sensation remains. Nitrous oxide and oral sedation are available.

Isolating the tooth

A small barrier called a rubber dam is placed around the tooth. It keeps the working area dry and free of saliva, which matters for disinfection, and it keeps irrigating solutions away from the rest of your mouth.

Accessing the pulp chamber

A small opening is made through the crown of the tooth to reach the chamber and the canal entrances.

Removing the infected pulp

The damaged tissue is removed from the chamber and from each canal. This is the step that resolves the pain, since the inflamed tissue generating it is what comes out.

Cleaning and shaping the canals

Fine instruments clean along the full length of each canal, and irrigating solutions disinfect the space and flush out debris. Thoroughness here is what determines whether the treatment holds, and it is the reason the appointment takes the time it does.

Filling and sealing

Each canal is filled with gutta-percha, a biocompatible material that seals the space so bacteria cannot recolonize it, then sealed at the access opening.

Temporary or final restoration

A temporary filling closes the tooth if a second appointment or a crown is planned. Where treatment is completed in one visit, the tooth is restored and the crown appointment is scheduled.

Placing the crown

For back teeth, a crown follows within the next few weeks. This is what protects a hollow, more brittle tooth from fracturing under chewing forces, and delaying it is the most common reason a successfully treated tooth is later lost.

Why Root Canals Have a Worse Reputation Than They Deserve

Root canals have a long-standing reputation for being painful, but modern treatment is very different. Advances in anesthesia, technology, and imaging have made the procedure far more comfortable than many people expect. In fact, the pain is usually caused by the infection, not the treatment itself.

During the procedure, your tooth is thoroughly numbed, and most patients feel little more than pressure. Root canal therapy removes the source of the pain, providing lasting relief. If dental anxiety has kept you from seeking care, we also offer sedation options to help you feel more relaxed throughout your visit.

Do Not Wait Out a Severe Toothache

An infected tooth does not resolve on its own, and every week that passes risks more bone around the root and a lower chance of saving the tooth. Root canal therapy relieves the pain and keeps the tooth, which is a considerably better outcome than extraction followed by replacement.

Frequently Asked Questions About Root Canal Therapy

The procedure itself is comfortable, because the tooth is numbed thoroughly with local anesthetic and tested before any work begins. What patients feel is pressure and vibration rather than pain, and studies consistently find root canal treatment rated similarly to having a filling placed. The severe pain most patients associate with root canals comes from the infection they arrived with, and that pain resolves once the infected tissue is removed. Nitrous oxide and oral sedation are available for patients who feel anxious.

Cost depends on which tooth is treated, since molars have more canals and take considerably more time than front teeth. The crown that follows is a separate cost and should be factored into your planning from the start. Most dental plans cover root canal therapy under a basic or major restorative category, though the percentage varies. Our team verifies your benefits before treatment and provides a written breakdown including the crown.

You can, and it is sometimes the right choice, but it is rarely the cheaper or simpler path once everything is accounted for. An extracted tooth leaves a space where neighboring teeth drift, the opposing tooth moves out of position and the bone that held the root begins resorbing. Replacing it with an implant or bridge generally costs more than root canal therapy and a crown combined. Our dentists will tell you honestly when a tooth is not worth saving, but where it can be saved, keeping it is usually the better outcome.

Root canal therapy has a high success rate, and treated teeth commonly last decades, with many lasting the rest of the patient's life. The most significant factor is whether the tooth receives a crown afterward, particularly for back teeth, since a treated tooth is hollow and more brittle and can fracture under normal chewing forces without full coverage. Skipping or delaying the crown is the most common reason a successful root canal eventually ends in extraction.

For back teeth, almost always. Root canal therapy removes the tissue from inside the tooth, leaving it hollow, without a blood supply and considerably more prone to splitting. Molars and premolars take heavy force during chewing, and a vertical fracture running into the root generally means the tooth cannot be saved. Front teeth take less force and can sometimes be restored with a filling instead, which our dentist will assess for your specific tooth.

No. Antibiotics cannot reach inside the sealed canal space where the infection lives, because that space has lost its blood supply. They may reduce swelling and ease symptoms temporarily, which sometimes makes patients think the problem has resolved, but the infection returns until the source is removed. Antibiotics are occasionally prescribed alongside treatment where infection has spread into surrounding tissue, as a supplement to root canal therapy rather than a substitute for it.

The infection continues spreading. It moves out through the root tip into the surrounding bone, destroying bone around the root and reducing the likelihood the tooth can be saved. From there it can reach the tissues of the face and neck, which becomes a medical emergency in serious cases. Along the way the pain typically worsens, and a tooth that could have been treated may reach the point where extraction is the only option left.
