A painful or infected tooth does not always need to be removed. Root canal treatment in Las Vegas, Nevada, can relieve discomfort, stop infection from spreading and preserve the natural tooth when enough healthy structure remains.
At Preferred Family Dentistry, Dr. Salmeh Jafarifar evaluates the source of your symptoms and explains whether root canal therapy is appropriate. Treatment is planned around the condition of your tooth, your comfort and the restoration needed to protect it afterward.
Call 702-433-0355 today if you have persistent tooth pain, lingering sensitivity, swelling or another sign of infection.
What Is Root Canal Treatment?
Root canal treatment is used to save a tooth when the soft tissue inside it, known as the pulp, becomes inflamed, infected or severely damaged. The pulp contains nerves, blood vessels and connective tissue. When bacteria reach this area through deep decay, a crack or another source of damage, the resulting inflammation can cause significant discomfort.
During treatment, the affected pulp is removed from the inside of the tooth. The canals are then cleaned, disinfected, shaped and sealed to reduce the risk of bacteria returning.
Once the inner infection has been addressed, the tooth is restored so it can continue contributing to your bite and smile. Depending on how much healthy structure remains, this may involve a tooth-colored filling or a dental crown.
Signs You May Need a Root Canal
Tooth pain can have several causes, and symptoms alone cannot confirm whether root canal therapy is necessary. A dental examination and diagnostic imaging are needed to identify the source of the problem.
Possible signs of an inflamed or infected tooth include:
- Persistent or severe tooth pain
- Pain when biting or chewing
- Lingering sensitivity to hot or cold temperatures
- Swelling or tenderness near a tooth
- A pimple-like bump on the gums
- Darkening or discoloration of a tooth
- A cracked, broken or deeply decayed tooth
- Discomfort that spreads toward the jaw, ear or nearby teeth
Symptoms may temporarily decrease if the nerve tissue inside the tooth dies, but the infection can remain. A tooth that stops hurting is not necessarily healthy, particularly if swelling, drainage or pressure continues.
Contact our office promptly if you notice these symptoms. If you are experiencing significant pain, swelling or another urgent concern, visit our Emergency Dentistry page or call 702-433-0355 for guidance.
What Causes an Infection Inside a Tooth?
The outer enamel and dentin normally protect the pulp from bacteria. Infection can develop when damage creates a pathway into the center of the tooth.
Common causes include:
- Deep tooth decay
- A crack or fracture
- A large or damaged filling
- Repeated dental treatment on the same tooth
- Trauma to the tooth
- Wear that exposes or weakens deeper tooth structure
Some cracks and infections are difficult to see without a detailed examination. Dr. Jafarifar will evaluate the tooth, surrounding gums, bite and existing dental work before recommending treatment.
How Root Canal Treatment Saves Your Natural Tooth
Root canal therapy removes infected tissue from inside the tooth while preserving the outer structure and roots. This allows the treated tooth to remain in place rather than leaving an open space in your smile.
Keeping a natural tooth can help:
- Maintain your normal bite
- Support comfortable chewing
- Prevent nearby teeth from shifting into an empty space
- Preserve the appearance of your smile
- Avoid or postpone tooth-replacement treatment
Saving the tooth is not always possible. If a fracture extends too far below the gumline or too little healthy structure remains, another treatment may be safer. Dr. Jafarifar will explain the condition of the tooth and the realistic options available.
What to Expect During a Root Canal Evaluation
Your visit begins with a conversation about your symptoms, including when the discomfort started, what triggers it and whether it has changed. Dr. Jafarifar will then examine the tooth and surrounding tissues.
Your evaluation may include:
- Checking the tooth for decay, cracks or damage
- Testing its response to temperature or pressure
- Evaluating discomfort when you bite
- Examining the gums for swelling or drainage
- Reviewing existing fillings, crowns or other restorations
- Taking digital X-rays to view the roots and surrounding bone
Digital X-rays can help reveal decay, infection near the root, changes in supporting bone and other concerns that are not visible above the gumline. Dr. Jafarifar will review the findings with you and explain why root canal treatment or another form of care may be recommended.
The Root Canal Treatment Process
The details of treatment depend on the tooth and the extent of the infection, but the general process includes several important steps.
Comfort and Local Anesthesia
The area around the tooth is numbed with local anesthesia before treatment begins. Tell our team if you feel nervous, have difficulty becoming numb or have had an uncomfortable dental experience in the past.
Comfort amenities such as ceiling-mounted televisions, blankets and pillows are available to help make longer appointments more manageable.
Removing the Affected Pulp
A small opening is made in the tooth so the damaged or infected pulp can be removed. Dr. Jafarifar cleans the narrow spaces inside the roots and addresses bacteria and debris within the canal system.
Cleaning and Sealing the Canals
The canals are carefully shaped and disinfected before being filled and sealed. This step helps prevent bacteria from easily re-entering the cleaned spaces.
Restoring the Tooth
After root canal therapy, the tooth needs a final restoration to seal the opening and protect the remaining structure. A smaller access area may sometimes be restored with a composite dental filling.
Teeth that have lost more structure, particularly back teeth exposed to heavier chewing pressure, may need a dental crown. The crown covers and reinforces the visible portion of the tooth to reduce the risk of future fracture.
Do You Need a Crown After a Root Canal?
Not every root canal-treated tooth requires the same restoration. The recommendation depends on which tooth was treated, how much structure remains, the size of existing fillings and the amount of pressure placed on the tooth.
A crown may be recommended when:
- The tooth has a large filling or significant decay
- A crack or fracture has weakened the structure
- The tooth is used for heavy chewing
- Removing decay and infected tissue leaves thin walls
- Additional coverage is needed to protect the tooth
Dr. Jafarifar has completed thousands of crowns, fillings and other restorative cases during her career. She will evaluate the remaining tooth structure and recommend the type of restoration needed for long-term protection rather than automatically using the same solution for every patient.
Is Root Canal Treatment Painful?
Root canal therapy is intended to relieve the pain caused by inflammation or infection. With local anesthesia, many patients describe the appointment as similar to receiving other restorative dental treatment.
The tooth and surrounding tissues may feel tender after the procedure, particularly if there was significant infection or inflammation beforehand. This discomfort is generally temporary. Our team will explain what you can expect, how to care for the area and when to contact us about continuing or worsening symptoms.
Do not delay an evaluation solely because you are concerned about discomfort. An untreated infection can become more painful and may eventually reduce the possibility of saving the tooth.
How Long Does Root Canal Treatment Take?
The number and length of appointments depend on the tooth, the complexity of its roots and the severity of the infection. Some teeth may be treated in one appointment, while others require more than one visit.
Your overall treatment timeline may also include a separate appointment for the final filling or crown. Dr. Jafarifar will explain the expected sequence after evaluating the tooth.
Root Canal Treatment vs. Tooth Extraction
Root canal treatment and extraction address an infected tooth in different ways. Root canal therapy removes the infected tissue while keeping the tooth in place. Extraction removes the entire tooth.
Preserving the tooth is generally considered when:
- The roots and surrounding bone provide adequate support
- The tooth can be cleaned and sealed effectively
- Enough structure remains for a stable restoration
- The tooth can continue functioning comfortably
Extraction may be recommended when a tooth is fractured beyond repair, lacks sufficient support or cannot be predictably restored. Removing a tooth may also create the need for replacement with a dental implant, partial denture or dental bridge.
Dr. Jafarifar will discuss the advantages, limitations and long-term considerations of each option before treatment begins.
Can Antibiotics Replace Root Canal Treatment?
Antibiotics may sometimes be prescribed when an infection has spread beyond the tooth or caused significant swelling. However, medication alone usually cannot remove infected pulp or clean bacteria from inside the root canal system.
Symptoms may improve temporarily while the source of infection remains. Definitive dental treatment is generally needed to address the affected tooth. Do not use leftover antibiotics or delay an examination because discomfort has temporarily decreased.
Benefits of Root Canal Therapy
When the tooth can be restored successfully, root canal treatment may provide several important benefits:
- Relief from pain caused by inflamed or infected pulp
- Removal of infection from inside the tooth
- Preservation of the natural tooth and roots
- Continued support for normal chewing and bite alignment
- Reduced risk of infection spreading to nearby tissues
- Avoidance of an empty space and immediate tooth-replacement planning
The long-term outlook depends on the original condition of the tooth, the quality of the final restoration and your ongoing dental care.
How to Care for Your Tooth After Treatment
Follow the instructions provided after your appointment and avoid chewing hard foods on the treated tooth until Dr. Jafarifar confirms that it is adequately restored.
To protect the tooth:
- Brush and floss consistently
- Keep the area around the tooth clean
- Avoid biting hard objects
- Complete the recommended crown or filling without unnecessary delay
- Keep routine dental exams and teeth cleanings
- Call our office if pain, swelling or pressure returns
A root canal-treated tooth can still develop decay or gum disease. Continued preventive care is necessary even though the nerve tissue has been removed.

FAQ About Root Canal Treatment
How do I know whether I need a root canal?
Persistent pain, lingering temperature sensitivity, swelling, pain when biting or a pimple on the gums may indicate an infected tooth. A dental exam and digital X-rays are needed to determine whether root canal therapy is appropriate.
Does root canal treatment hurt?
Local anesthesia is used to numb the treatment area. Many patients experience relief after the infected tissue is removed, although temporary tenderness may occur afterward.
How many visits does a root canal require?
Some cases may be completed in one treatment visit, while others require more than one. A separate appointment may also be needed to place the final crown or filling.
Do I need a crown after root canal therapy?
It depends on the location and condition of the tooth. Back teeth and teeth with significant structural loss often need crowns, while another restoration may be appropriate in selected cases.
Can antibiotics cure an infected tooth?
Antibiotics may help manage infection that has spread into surrounding tissues, but they generally do not remove infected pulp from inside the tooth. Dental treatment is usually needed to address the source.
How soon can I return to normal activities?
Many patients return to routine activities shortly after treatment. Follow the instructions provided by our team and avoid chewing heavily on the tooth until it has received its final restoration.
Can a tooth become infected again after a root canal?
Although treatment is designed to remove infection and seal the tooth, new decay, cracks, restoration problems or complex canal anatomy can sometimes lead to additional concerns. Contact us if symptoms return.
