Saving Teeth and Relieving Pain

Root canal therapy has an unfair reputation. The truth? Root canals don’t cause pain—they relieve it. If you’re experiencing tooth pain, a root canal is often the only way to save your tooth and eliminate your discomfort.

At South Holston Dental Designs, we perform gentle, comfortable root canal therapy using modern techniques that make the procedure no more uncomfortable than getting a filling. Our goal is to save your natural tooth and get you out of pain as quickly as possible.

What Is Root Canal Therapy?

Inside every tooth is soft tissue called pulp that contains nerves, blood vessels, and connective tissue. When this pulp becomes infected or inflamed—whether from deep decay, a crack, trauma, or repeated dental procedures—it causes pain and can lead to an abscess if left untreated.

Root canal therapy removes the infected or damaged pulp, cleans and disinfects the inside of the tooth, and seals it to prevent future infection. The procedure saves your tooth and eliminates pain.

Common causes of pulp damage:

• Deep decay reaching the pulp
• Cracked or fractured tooth
• Trauma or injury to the tooth
• Large fillings that irritate the pulp
• Repeated dental procedures on the same tooth
• Untreated cavity that progresses

Signs You May Need a Root Canal

Pain That Won’t Go Away

Persistent tooth pain, especially pain that wakes you at night or is triggered by chewing, hot, or cold temperatures, often indicates pulp damage. The pain may be constant or come and go.

Extreme Sensitivity

If your tooth is extremely sensitive to hot or cold temperatures and the sensitivity lingers long after the stimulus is removed, the pulp may be damaged.

Swelling or Tenderness

Swelling in the gums near a painful tooth, tenderness when touching the tooth or gums, or a pimple-like bump on the gum can indicate infection.

Tooth Discoloration

A tooth that’s darkening or turning grayish may have pulp damage from trauma or decay.

Abscess

A dental abscess—a pocket of pus caused by bacterial infection—causes severe pain, swelling, fever, and a bad taste in your mouth. This is a dental emergency requiring immediate treatment.

Don’t wait for symptoms to worsen. The sooner we treat infected pulp, the better your outcome and the more likely we are to save your tooth.

The Root Canal Process

Modern root canal therapy is nothing like the horror stories you may have heard. With today’s anesthesia and techniques, most patients report the procedure is no more uncomfortable than having a cavity filled.

Step 1: Diagnosis and X-Rays

We take x-rays to see the extent of infection and the shape of your root canals. This helps us plan your treatment and ensures we address all areas of infection.

Step 2: Anesthesia

We thoroughly numb the area around your tooth. You shouldn’t feel pain during the procedure. If you experience any discomfort, let us know immediately so we can provide additional anesthesia.

For anxious patients, we offer nitrous oxide sedation to help you relax.

Step 3: Isolation

We place a small rubber sheet called a dental dam around your tooth to keep it dry and isolated during treatment. This also protects you from swallowing any materials used during the procedure.

Step 4: Accessing the Pulp

We create a small opening in the crown of your tooth to access the infected pulp chamber and root canals.

Step 5: Cleaning and Shaping

Using specialized instruments, we carefully remove the infected or damaged pulp tissue from the chamber and root canals. We then clean and disinfect the empty space and shape the canals to prepare them for filling.

This step is crucial—thoroughly removing all infected tissue and bacteria prevents future problems.

Step 6: Filling the Canals

Once cleaned and dried, we fill the root canals with a biocompatible material called gutta-percha, which is sealed in place with adhesive cement. This prevents bacteria from re-entering.

Step 7: Temporary Filling

We place a temporary filling to close the opening in your tooth. This protects the canals until your permanent restoration is placed.

Step 8: Final Restoration

A tooth that’s had root canal therapy is more fragile than a healthy tooth. In most cases, you’ll need a crown to protect the tooth and restore full function. We’ll discuss the timing and type of restoration needed for your specific situation.

Time required: Most root canals are completed in one or two appointments, each lasting 60-90 minutes.

Root Canal vs. Extraction: Why Save Your Tooth?

When a tooth is severely damaged or infected, you have two options: root canal therapy or extraction. While extraction may seem simpler, saving your natural tooth is almost always the better choice.

Benefits of Saving Your Tooth

Preserves natural chewing function – Nothing works as well as your natural tooth

Prevents shifting – Adjacent teeth won’t drift into the gap, causing bite problems

Maintains jawbone – Your natural tooth root stimulates the bone, preventing deterioration

More cost-effective long-term – While a root canal plus crown costs more initially than extraction, replacing a missing tooth costs even more

Better for neighboring teeth – Replacing a missing tooth with a bridge requires grinding down healthy adjacent teeth

Avoids further treatment – Once you extract a tooth, you’ll eventually need an implant, bridge, or partial denture to replace it

When Extraction Might Be Necessary

In some cases, a tooth can’t be saved:

• The tooth is fractured below the gum line
• There isn’t enough tooth structure remaining to restore
• The root is severely damaged
• There’s advanced bone loss from gum disease

If extraction is necessary, we’ll discuss tooth replacement options including dental implants.

After Your Root Canal

What to Expect

Mild discomfort – Some tenderness is normal for a few days, especially when chewing. Over-the-counter pain medication usually provides adequate relief.

Sensitivity – Your tooth may feel slightly different or sensitive for a few days as inflammation subsides.

Healing time – Most patients feel back to normal within a few days. Any severe pain should be reported immediately.

Post-Treatment Care

Follow medication instructions – Take any prescribed antibiotics as directed to clear infection

Avoid chewing on that tooth – Until your permanent crown is placed, avoid chewing on the treated tooth

Maintain oral hygiene – Continue brushing and flossing normally

Schedule your crown – Don’t delay getting your permanent restoration. The tooth is more fragile after root canal therapy and needs protection.

Warning Signs to Call Us

Contact us immediately if you experience:

• Severe pain that doesn’t respond to pain medication
• Swelling inside or outside your mouth
• Visible swelling of your face or neck
• Allergic reaction to medication (rash, itching, hives)
• Return of original symptoms
• Bite feels uneven
• Temporary filling comes out

How Long Do Root Canals Last?

With proper care and a quality crown to protect it, a tooth that’s had root canal therapy can last the rest of your life. Success rates for root canal therapy are very high—over 95% when performed correctly.

Factors affecting longevity:

• Getting a crown to protect the tooth
• Maintaining good oral hygiene
• Regular dental checkups
• Avoiding trauma to the tooth
• Not delaying treatment until damage is severe

The key is getting your permanent crown placed promptly after the root canal. Don’t let months go by with just a temporary filling—this leaves the tooth vulnerable to fracture.

Root Canal Myths vs. Reality

Myth: Root Canals Are Extremely Painful

Reality: Root canals relieve pain, they don’t cause it. With modern anesthesia, most patients report the procedure is no more uncomfortable than getting a filling. The pain you’re experiencing before treatment is from the infection—the root canal eliminates that pain.

Myth: It’s Better to Just Pull the Tooth

Reality: Saving your natural tooth is almost always preferable to extraction. Extracting a tooth means you’ll need to replace it (implant, bridge, or partial), which costs more and requires additional procedures.

Myth: Root Canals Cause Illness

Reality: This myth stems from long-debunked research from the 1920s. Modern scientific evidence shows root canals are safe. Leaving an infected tooth untreated is what poses health risks—bacteria from dental infections can spread to other parts of your body.

Myth: If the Tooth Doesn’t Hurt, You Don’t Need a Root Canal

Reality: Not all infected teeth are painful. Sometimes pulp dies slowly without pain. We may diagnose the need for a root canal through x-rays or testing even if you’re not experiencing discomfort.

Root Canal Retreatment

In rare cases, a tooth that’s had root canal therapy may not heal properly or may develop new problems years later. This can happen if:

• Complex canal anatomy prevented complete cleaning initially
• New decay exposes the root canal filling to bacteria
• A crown or restoration is delayed or becomes defective
• The tooth suffers new trauma

Root canal retreatment involves reopening the tooth, removing the previous filling material, cleaning the canals again, and resealing them. Success rates for retreatment are still quite good, though not quite as high as initial treatment.

If retreatment isn’t successful, a minor surgical procedure called an apicoectomy may be recommended to save the tooth.

Cost of Root Canal Therapy

Root canal therapy costs vary based on which tooth needs treatment:

Front teeth – Less expensive (single canal, easier to access)

Premolars – Moderate cost (one or two canals)

Molars – Higher cost (three or four canals, more complex)

Insurance typically covers 50-80% of root canal therapy after your deductible.

Remember to factor in the cost of the crown that will protect your tooth after treatment. While the combined cost may seem high, it’s less than extraction plus implant replacement—and you get to keep your natural tooth.

We provide detailed cost estimates before beginning treatment and will file insurance claims on your behalf. Financing options are available.
