Root Canal Therapy: Saving a Damaged or Infected Tooth
When a tooth becomes severely decayed, infected, or injured, the tissue inside the tooth can become inflamed or damaged. In these situations, root canal therapy may be recommended to remove the infection, relieve discomfort, and preserve the natural tooth whenever possible.
At Miracle Dental, our goal is always to help patients maintain healthy, functional teeth. A root canal procedure is a common and effective treatment that can often prevent the need for tooth extraction while restoring comfort and oral health.
Many people feel nervous when they hear the words "root canal," but modern treatment techniques are designed to make the procedure as comfortable and efficient as possible. Understanding what is a root canal and why it may be necessary can help you feel more informed about your dental care options.
What Is a Root Canal?
Root canal treatment is performed to save a tooth that has been affected by infection, deep decay, trauma, repeated dental work, or a large filling. The purpose of root canal treatment is to preserve your natural tooth instead of removing it.
Years ago, before root canal treatment was available, a severely infected tooth usually had to be extracted. Today, root canal therapy allows us to save many of those teeth and restore their function.
During the root canal procedure, the dentist removes the decay and infected tissue, thoroughly cleans the root canals, fills and seals them, and restores the tooth. The goal is for you to keep your natural tooth, chew comfortably, and avoid the problems that can come with missing teeth.
One of the most common questions patients ask is, "What is a root canal?" A root canal is a dental procedure used to treat infection or damage within the pulp of a tooth. The pulp is the soft tissue located inside the tooth that contains nerves, blood vessels, and connective tissue.
When the pulp becomes infected or inflamed, the condition cannot heal on its own. Without treatment, infection can spread, pain may worsen, and the affected tooth could eventually require extraction.
Why Might I Need a Root Canal?
Several dental conditions can affect the pulp inside a tooth. Root canal treatment is often recommended when infection or inflammation has reached the innermost portion of the tooth.
Common reasons for needing a root canal include:
- Deep tooth decay that extends into the pulp
- A cracked or fractured tooth
- Repeated dental procedures on the same tooth
- Dental trauma or injury
- An abscess or infection near the root of the tooth
- Advanced damage to the nerve tissue
In many cases, root canal therapy allows patients to keep a natural tooth that might otherwise require removal.
Signs You May Need Root Canal Therapy
The symptoms of an infected tooth can vary from person to person. Some patients experience significant discomfort, while others may have few noticeable symptoms.
Signs that may indicate the need for a root canal include:
- Persistent tooth pain
- Sensitivity to hot or cold temperatures
- Discomfort when biting or chewing
- Swelling of the gums near a tooth
- A small pimple-like bump on the gums
- Tenderness around the affected tooth
- Tooth discoloration
It is important to note that some teeth requiring root canal therapy may not produce noticeable symptoms. Regular dental examinations can help identify problems before they become more serious.
The number one symptom is pain. It may begin as mild sensitivity to hot or cold but can progress to severe, throbbing pain that wakes you up in the middle of the night. Swelling or an abscess are also common signs that root canal treatment may be needed.
The textbook symptoms I discuss with my patients include spontaneous tooth pain, pain that lingers after eating or drinking something cold, and pain that continues for several minutes—or sometimes even hours. If your tooth pain wakes you up at night, that is a very strong indication that you may need root canal therapy.
Benefits of a Root Canal Procedure
A root canal procedure offers several important benefits for both oral health and overall comfort.
- Removes infection from within the tooth
- Preserves the natural tooth whenever possible
- Relieves pain and discomfort caused by infection
- Helps prevent infection from spreading
- Maintains normal chewing and biting function
- Supports long-term oral health
- Eliminates the need for extraction in many cases
Saving a natural tooth is often beneficial because it helps maintain proper tooth alignment and avoids the need for more extensive tooth replacement treatments.
Why Not Simply Remove the Tooth?
Some patients wonder whether extracting a damaged tooth is easier than having a root canal. While extraction may be necessary in certain situations, preserving a natural tooth is generally preferable whenever possible.
Removing a tooth can leave a gap that may affect chewing, appearance, and bite function. Over time, neighboring teeth may shift into the empty space, potentially creating additional dental concerns.
Root canal therapy allows the tooth to remain in place while removing the source of infection. This often helps maintain better long-term oral function and stability.
What to Expect During a Root Canal Procedure
A root canal procedure is typically completed in one or more appointments, depending on the complexity of the case and the condition of the tooth.
Examination and Diagnosis
Your dentist will evaluate the affected tooth and may take diagnostic X-rays to determine the extent of the infection or damage. These images help identify changes within the tooth and surrounding bone.
Numbing the Area
Before treatment begins, local anesthesia is administered to help ensure the procedure is comfortable. Most patients find that modern root canal treatment feels similar to receiving a filling.
The first step is making sure you are completely comfortable with local anesthesia. Once the tooth is numb, the dentist removes the infected nerve tissue and thoroughly cleans the root canal system. The canals are then filled and sealed to help prevent future infection.
Cleaning the Inside of the Tooth
A small opening is created in the top of the tooth to access the pulp chamber and root canals. Specialized instruments are used to remove damaged pulp tissue, bacteria, and debris from within the tooth.
The canals are then carefully cleaned and shaped in preparation for sealing.
Filling and Sealing
After the interior of the tooth has been thoroughly disinfected, the canals are filled with a biocompatible material and sealed. This helps prevent bacteria from reentering the tooth.
Depending on the treatment plan, the tooth may receive a temporary restoration before a permanent filling or crown is placed.
After the canals are sealed, the upper portion of the tooth is rebuilt using a material called a buildup. Think of a tooth that has been damaged by decay. Bacteria enter the tooth and infect the nerve, creating an infection at the tip of the root. During root canal treatment, the infected nerve is removed, the canals are cleaned and sealed, and the tooth is rebuilt. In most cases, a dental crown is then recommended to protect and strengthen the tooth.
Before the procedure begins, I always explain why the root canal is needed and what you can expect throughout treatment. At Miracle Dental, we want our patients to feel informed and comfortable before, during, and after the procedure.
Once your root canal treatment is complete, we provide detailed aftercare instructions and prescribe medication if needed to help keep you comfortable during recovery. Modern root canal therapy has become a very routine procedure, and patients should not be afraid of it.
At Miracle Dental, we perform root canal procedures on a regular basis and have extensive experience helping patients feel relaxed and comfortable throughout treatment. We also offer sedation options for patients who experience dental anxiety or have heard frightening stories about root canals. Our goal is to make your experience as stress-free and comfortable as possible.
How Long Does a Root Canal Take?
Patients frequently ask, "How long does a root canal take?" The answer depends on several factors, including the location of the tooth, the number of canals involved, and the severity of the infection.
Many root canal procedures can be completed in a single appointment, while more complex cases may require multiple visits. Your dentist can provide a more accurate estimate after evaluating your individual situation.
The length of treatment varies from patient to patient, but preserving a natural tooth is often worth the additional time and care involved.
The Importance of a Dental Crown After Root Canal Therapy
Many teeth that undergo root canal treatment require a dental crown afterward. A crown helps protect the treated tooth and restore its strength and function.
Because the tooth may become more vulnerable to fracture after root canal therapy, a crown often provides additional support and durability. Posterior teeth, such as molars and premolars, frequently benefit from crown placement because they experience significant chewing forces.
Your dentist will discuss whether a crown is recommended as part of your treatment plan.
In almost 99% of cases, the answer is yes. By the time you need root canal treatment, especially on a molar, the tooth often has a large filling, extensive decay, or a crack. During the root canal procedure, the damaged tissue is removed, leaving the remaining tooth structure weaker than before.
After root canal therapy, the tooth no longer contains the nerve and blood vessels that once kept it healthy. Because of this, it becomes more brittle and is less able to withstand normal chewing forces.
That is why we strongly recommend placing a dental crown after root canal treatment. A dental crown protects the tooth, restores its original shape, and allows you to chew comfortably again.
I have many patients who stop after the root canal because the pain goes away. They feel better and think the treatment is complete. Please don't make that mistake. A root canal is only half of the treatment. Without the dental crown, the tooth has a much higher chance of cracking, which can undo all the time, effort, and money invested in saving it.
By the time a tooth requires root canal treatment, there is usually extensive decay that has reached the nerve. A significant amount of tooth structure has already been lost.
After root canal therapy, the tooth becomes hollow and much weaker. Without a dental crown, it is much more likely to crack or fracture during normal chewing.
For that reason, dentists almost always recommend placing a dental crown after a root canal to strengthen and protect the tooth. When considering root canal treatment, it is important to think of the root canal and the crown as one complete treatment plan.
If you know ahead of time that you are unable or unwilling to complete the dental crown afterward, it is important to discuss that with your dentist before beginning treatment. From my experience, many patients who only complete the root canal and never return for the crown eventually come back with a cracked tooth that can no longer be saved.
Recovery and Aftercare
Following root canal treatment, some mild tenderness or sensitivity is normal. This typically improves as the surrounding tissues heal and inflammation subsides.
To support recovery:
- Follow all post-treatment instructions
- Take medications as directed
- Avoid chewing on the treated tooth until it has been permanently restored
- Brush and floss regularly
- Attend any recommended follow-up appointments
Most patients can return to normal daily activities shortly after treatment.
Most patients experience mild discomfort for the first day or two after root canal treatment. Since the procedure involves treating the nerve of the tooth, some tenderness is completely normal.
Depending on your situation, we may prescribe antibiotics, although they are not always necessary. We will also recommend anti-inflammatory pain medication, and in some cases, a short course of steroids to help minimize swelling.
Follow all of your post-treatment instructions carefully. I also recommend avoiding chewing on the treated side for about a week to allow the tooth time to recover. After that, you should be able to return to normal function as directed.
Root Canal Cost Considerations
The cost of root canal treatment depends on the location of the tooth and the complexity of the procedure. Front teeth and premolars are generally less complex than molars, which often require more time, greater skill, and additional equipment.
Some teeth have curved roots or complex canal systems that may require referral to an endodontic specialist. In those situations, treatment costs may be higher.
The good news is that many dental insurance plans provide coverage for root canal treatment, although the amount covered varies by plan.
At Miracle Dental, I perform many root canal treatments in-house because it is one of the procedures I truly enjoy. Helping patients save their natural teeth is one of the most rewarding parts of what I do. Before treatment begins, we'll review your insurance benefits, explain your coverage, and clearly discuss all fees so there are no surprises.
During your consultation, the dental team can discuss your treatment plan and provide information regarding root canal cost based on your individual needs.
When Should I Contact a Dentist?
You should contact a dentist if you experience:
- Severe or persistent tooth pain
- Sensitivity that lingers after exposure to hot or cold temperatures
- Swelling around a tooth or gums
- Pain when chewing
- A cracked or injured tooth
- Signs of a dental abscess
- Changes in tooth color
Early evaluation can help identify the cause of your symptoms and determine whether a root canal or another treatment may be appropriate.

Can a Cracked Tooth Be Saved With a Root Canal?
In some cases, yes. If the crack extends only into the pulp chamber, where the nerve is located, root canal treatment may allow us to save the tooth. However, if the crack extends farther down into the root, the tooth may no longer be restorable.
Using dental X-rays, advanced technology, and a thorough examination, we can determine the best treatment option. The sooner you seek treatment, the better the chances of saving your natural tooth before extraction becomes necessary.
How Should You Prepare for a Root Canal?
By the time you come in for root canal treatment, your dentist has most likely already explained why the procedure is needed. I always encourage patients to learn a little about root canal therapy beforehand and come prepared with any questions they may have so they feel comfortable.
Be sure to let your dentist know if you have any medication allergies, medical conditions, or medications that you are currently taking. This helps us plan your treatment safely.
At Miracle Dental, we perform root canal procedures regularly. I personally complete many root canal treatments and will do everything possible to make sure you feel comfortable throughout your visit.
What's the Difference Between a Root Canal and a Dental Implant?
A root canal is performed when your natural tooth can still be saved. A dental implant, on the other hand, is designed to replace a tooth that has already been lost or must be extracted.
Root canal treatment is typically completed in one appointment that lasts between one and several hours, depending on the complexity of the tooth. Afterward, a dental crown is usually placed to protect the tooth.
Dental implant treatment is a much longer process that can take several months because the implant must heal and integrate with the surrounding bone.
Whenever possible, saving your natural tooth is almost always the preferred option. If a root canal eventually fails years later, the tooth can still be extracted and replaced with a dental implant. However, once a natural tooth has been removed, it cannot be replaced with your original tooth. Be sure you understand all of your options before deciding to have a tooth extracted.
