Root canal therapy
Save the tooth, end the pain
A root canal isn't what your grandparents experienced. With modern technique and a good local anesthetic, it's much closer to a long filling visit — and it saves your natural tooth.
What "root canal" actually means
Inside every tooth is a soft tissue called the pulp — it contains the nerves and blood vessels that kept the tooth alive while it was developing. When the pulp gets infected (usually from deep decay, a crack, or trauma), it causes pain and can lead to an abscess if left untreated. A root canal removes that infected pulp, cleans and disinfects the inner chambers, and seals the tooth so bacteria can't get back in.
It's called non-surgical because there are no incisions, no stitches, and no surgical access. Everything is done through a small opening in the top of the tooth.
When you might need one
- A severe toothache, especially one that throbs or wakes you up.
- Sensitivity to hot or cold that lasts more than a few seconds after the stimulus is removed.
- Pain when you bite down or apply pressure on a specific tooth.
- Swelling or tenderness in the gum next to a particular tooth.
- A "pimple" on the gum that may drain — a sign of an abscess.
- Tooth discoloration after trauma — a tooth that turns grayish often has dying pulp inside.
Sometimes a tooth needs a root canal without any symptoms at all — we may catch the infection on a routine X-ray.
The procedure, step by step
- 1. Diagnosis. Examination, X-rays, and pulp testing to confirm the tooth needs a root canal and rule out other causes.
- 2. Numbing. Topical gel, then local anesthetic. We don't begin until you're fully numb.
- 3. Access. A small opening in the top of the tooth gives us access to the pulp chamber.
- 4. Cleaning. Specialized files clean out the infected pulp tissue from inside each canal of the tooth.
- 5. Disinfection. The inner chambers are irrigated with disinfectant solution.
- 6. Filling & sealing. The canals are filled with a biocompatible material (gutta-percha) and the tooth is sealed to prevent reinfection.
- 7. Crown (separate visit). Most root-canal-treated teeth, especially back teeth, get a crown a few weeks later to protect them from fracture.
Why doing it in-house matters
Most general dentists refer root canals to endodontists (root canal specialists). We perform them in-house. That means no separate referral, no extra office visit, no different team — your root canal and your crown happen in the same chair, with the same dentist who's been seeing you. For complex cases, we still refer to a specialist — but most everyday root canals can be done right here on Thomson Drive.
Common questions
Frequently asked
- What is a root canal?
- A root canal is a procedure that removes infected or inflamed tissue (the pulp) from inside a tooth, cleans and disinfects the inner chambers, and seals the tooth to prevent reinfection. It's called non-surgical because there are no incisions or stitches — everything is done through a small opening in the tooth crown.
- Does it hurt?
- No — and this is the part that surprises most patients. The toothache that brings people in is from the infected pulp. Once we numb the area and remove the infected tissue, the pain stops. Most patients report that the procedure itself feels similar to having a filling done.
- Why save the tooth instead of just pulling it?
- Your natural tooth — even a tooth that's needed a root canal — chews better, lasts longer with proper care, and preserves the bone around the socket. Pulling a tooth and replacing it with an implant or bridge is a bigger procedure and a larger expense than saving the original.
- Who performs the root canal — a specialist or a general dentist?
- We perform root canals in-house at Lynchburg Dentist. That means no specialist referral, no separate office visit, no second team. For complex cases (severely curved canals, retreatment of failed cases), we may refer to an endodontist.
- How many visits does it take?
- Most root canals are completed in one or two visits, depending on the tooth and the complexity of the infection. Each visit is typically 60 to 90 minutes.
- Will I need a crown after?
- For back teeth, almost always yes — a root canal treated tooth becomes more brittle over time, and a crown protects it from fracture. We typically schedule the crown appointment within a few weeks of the root canal.
- What are the signs that I might need a root canal?
- Severe or lingering toothache, especially with cold or hot sensitivity that lasts more than a few seconds. Pain when chewing or applying pressure. Swelling or tenderness in the gums near a specific tooth. A pimple-like bump on the gum near a tooth. Sometimes there are no symptoms — and we find the issue on an X-ray.
- How long does the treated tooth last?
- With a properly placed crown and good oral hygiene, a root-canal-treated tooth can last decades — often the rest of your life. Studies show success rates above 90% over 10 years.
