Root canal treatment in Irving, TX

What a root canal actually does

If you’ve been told you need root canal treatment, it helps to know what’s happening inside the tooth. Every tooth has soft tissue called the pulp, which holds nerves and blood vessels. Deep decay, a crack or a hard hit can let bacteria in, and the pulp becomes inflamed or infected. That’s what causes the deep, throbbing ache, and left alone, the infection can spread into the bone and form an abscess.

Root canal treatment removes the damaged pulp, cleans and disinfects the canals inside the roots, and seals them. The tooth stays in your mouth, held by its own roots, so you keep chewing on your natural tooth. Our general dentists provide root canal treatment here in Irving. If a tooth has unusually complex anatomy or needs retreatment, we may refer you to an endodontist and tell you why.

Signs you might need root canal treatment

• Sensitivity to hot or cold that lingers
• Throbbing pain, especially at night or lying down
• Pain when you bite or press on the tooth
• A tooth that has darkened or turned gray
• Swelling or tenderness in the gum near one tooth
• A pimple-like bump on the gum that may drain
• A deep cavity or crack found on an x-ray

Root canal myths vs. reality

Most fears about root canals come from stories that are decades out of date. Here’s what’s true today:

What the appointment feels like

We start by numbing the tooth and the gum around it, then wait and test before we begin. Badly inflamed teeth can be stubborn to numb, so we take extra time when needed. Most patients feel pressure, not pain. A thin rubber shield goes around the tooth to keep it clean and dry and to keep the work out of your throat.

Most root canals take about 60 to 90 minutes. Our treatment rooms have TVs, you’re welcome to bring headphones, and you can raise a hand for a break at any point. If dental visits make you anxious, ask about comfort and sedation options.

Afterward, the tooth may feel tender for a few days, especially when you bite. Over-the-counter pain relievers taken as directed usually handle it. Many people go straight back to work.

Why you’ll usually need a crown afterward

A tooth that needs a root canal has usually already lost a lot of structure to decay, cracks or old fillings, and the treatment requires an opening through the top. Back teeth take heavy chewing forces, so molars and premolars almost always need a dental crown to keep them from cracking. A front tooth with little damage can sometimes be restored with a filling instead.

We use digital impressions, with no goopy trays, and match the crown to the teeth around it. Until the crown is on, avoid chewing hard foods on that side. Putting off the crown is one of the most common reasons a root-canal-treated tooth ends up failing.

Root canal or extraction?

Pulling a tooth can look cheaper and faster on the day. But a missing tooth usually needs to be replaced with an implant or a bridge to prevent shifting and bone loss, and that often costs more than saving the tooth in the first place. Extraction makes sense when a tooth is cracked through the root, there isn’t enough healthy structure left to rebuild, or gum disease has destroyed the bone around it.

We’ll show you your x-rays, explain the long-term outlook for that specific tooth and give you written costs for both paths. For a detailed side-by-side, read our guide to root canal vs. extraction, or see our tooth extractions page.

What to expect, step by step

1. Diagnosis

   We test the tooth and take digital x-rays, plus a 3D CBCT scan when roots are complex, to see the canals and any infection.

2. Numbing and isolation

   We numb thoroughly and place a thin rubber shield around the tooth to keep it clean and dry.

3. Cleaning the canals

   Through a small opening, we remove the infected pulp, then shape and disinfect each canal.

4. Filling and sealing

   The canals are filled with a rubber-like material and sealed, and a filling closes the top of the tooth.

5. Crown

   Usually within a few weeks, a crown is placed to protect the tooth and restore full chewing strength.

Cost, insurance & financing

The cost of a root canal depends mostly on which tooth it is, because back teeth have more canals. As a rough DFW and national guide before insurance, front teeth often run about $700–$1,100, premolars about $800–$1,300 and molars about $1,000–$1,600. The crown afterward is a separate cost, commonly $1,000–$2,000.

What changes the price: the number and shape of the canals, whether the tooth was treated before, and the crown material. We give you a written estimate before we begin. Most PPO plans cover a portion of root canals and crowns, and financing through Cherry, Affirm or CareCredit can help, subject to approval. Details are on our insurance and financing page.
