Root Canal Treatment in Houston, TX

When the soft tissue inside a tooth—called the dental pulp—becomes infected or inflamed, a root canal can stop the damage and relieve the pain. Without care, the infection can spread, form an abscess, and eventually lead to tooth loss.

The goal of endodontic therapy is to remove the diseased pulp, disinfect the interior of the tooth, and fill the canals so bacteria can’t return. Afterward, the tooth is covered with a crown to restore strength. At Care Dental, Dr. Casandra Barnes performs root canal treatment to help patients in Houston, Aldine, and surrounding areas keep their natural teeth and avoid extractions.

Teeth aren’t solid—they have a hard outer shell of enamel, a supporting layer of dentin, and a central space that houses the pulp. The pulp contains nerves and blood vessels, so when decay or a crack reaches it, pain is often the result.

During a root canal, we make a small opening in the chewing surface of the tooth to access the pulp chamber. With specialized instruments, we gently remove the infected tissue from every canal. The inside is then scrubbed with disinfecting solutions to kill bacteria. Once the tooth is clean and dry, we fill the canals with a rubbery material called gutta-percha and seal the opening. This stops the infection and lets the bone around the tooth heal.

Several symptoms point to a possible need for endodontic treatment, though only a thorough exam with X-rays can confirm the diagnosis. You might notice:

• A toothache that intensifies when you bite down or chew
• Prolonged sensitivity to hot or cold, even after the source is removed
• Swollen, tender gums near a specific tooth
• A small bump on the gum that resembles a pimple (a fistula)
• A change in tooth color, often a grayish tint

Not all deep cavities end up needing a root canal. If the pulp is irritated but not yet infected, a filling or medicated dressing may suffice. At Care Dental, we use advanced imaging to assess the extent of damage before recommending any treatment. If a tooth is beyond saving—due to a vertical fracture or inadequate bone support—Dr. Barnes will explain why extraction makes more sense.

We walk you through every step so there are no surprises. Here’s the typical flow at our Houston office:

1. Numbing. We apply a local anesthetic to completely numb the tooth and surrounding area so you don’t feel pain.
2. Isolation. A thin rubber sheet called a dental dam is placed to isolate the tooth, keeping it clean and free of saliva.
3. Opening. A tiny access hole is made through the top of the tooth to reach the pulp.
4. Cleaning. Delicate tools remove the damaged pulp, then the canals are widened and flushed with an antimicrobial solution.
5. Filling. The canals are filled with gutta-percha and a sealing agent to block reinfection.
6. Temporary Cover. The access hole is closed with a temporary filling until a permanent restoration is ready.
7. Crown. At a later visit, we shape the tooth and place a custom-made crown, which protects the tooth and brings back full biting function.

Some teeth—particularly front teeth—have fewer canals and may be completed more quickly. Molars are more complex and can take longer. We let you know the expected timeline during your consultation.

Most patients return to their daily activities right away. It’s common to feel mild soreness or sensitivity in the treated area for a few days, especially when chewing. Over-the-counter pain relievers like ibuprofen usually manage any discomfort.

Until you receive your permanent crown, steer clear of hard or sticky foods on the treated side. Keep up with regular brushing and flossing, but be gentle around the temporary filling. If you experience severe pain, worsening swelling after two days, or an allergic reaction, call our office at (832) 564-1800. For concerns outside regular hours, our phone system provides instructions for reaching the team.

Choosing a root canal offers several advantages:

• It removes the source of pain—infected pulp—so you feel better quickly.
• You keep your natural tooth, maintaining proper chewing and a complete smile.
• It stops infection from spreading to neighboring teeth or into the jawbone.
• You avoid the need for a bridge, implant, or partial denture.

There are also aspects to keep in mind. A tooth with no living pulp can become brittle over time. That’s why a crown is almost always recommended for back teeth and often for front teeth as well. While root canals have a high success rate, in rare instances the tooth may not heal as expected. Retreatment or a surgical procedure called an apicoectomy might be necessary. Dr. Barnes discusses these possibilities beforehand so you have a clear picture.

What you pay for root canal treatment depends on factors like which tooth is affected, the number of canals, and whether retreatment is involved. A crown is typically billed separately and will be included in your overall treatment estimate.

Care Dental works with most major dental insurance plans. Before we start any procedure, we confirm your benefits and provide a written breakdown of expected costs. We believe financial concerns shouldn’t prevent you from getting the care you need, so we are open about expenses and happy to review your options. Give us a call at (832) 564-1800 to learn more.

Your well-being guides everything we do. We follow strict infection control standards that align with CDC and ADA guidelines, including heat-sterilizing instruments, using single-use barriers, and testing our equipment regularly.

Comfort starts with effective anesthesia. We take the time to ensure your tooth is fully numb before beginning. Throughout the procedure, we watch for cues that you need a pause or have a question—just raise your hand and we’ll stop. Our team works hard to make your experience as relaxed as possible.

If you wake up with intense, throbbing pain, swelling in your face, or a visible bump on the gum, you may be dealing with a serious dental infection. These are signs the pulp is severely damaged and needs prompt care. We set aside same-day appointment slots for patients in this kind of distress.

During an emergency visit, our first priority is getting you out of pain. After numbing the area, we open the tooth, remove the infected pulp, and place a temporary medication. Once the infection is under control, we schedule a follow-up to complete the canals and plan your crown. While you wait to be seen, taking an over-the-counter anti-inflammatory as directed on the label may help; avoid placing heat on your face, as that can worsen swelling. Call (832) 564-1800 right away to be seen.
