Root Canal Therapy
Relieve the Pain. Preserve the Tooth.
Root canal therapy removes inflamed or infected tissue from inside a tooth, helping relieve discomfort while preserving the natural structure of your smile.
At Mandarin Dentistry, modern techniques and a calm, thoughtful approach make treatment far more comfortable than its reputation suggests.
Saving a Tooth From the Inside
Beneath the enamel and dentin of every tooth is a central space containing soft tissue called the pulp.
The pulp includes nerves, blood vessels, and connective tissue that help the tooth develop. Once the tooth is fully formed, it can continue to function without this tissue.
If the pulp becomes inflamed or infected, it cannot heal predictably on its own. Root canal therapy removes the compromised tissue, cleans and disinfects the internal spaces, and seals the tooth against future contamination.
The tooth is then restored to protect its structure and allow it to function comfortably again.
The pulp may become inflamed or infected because of:
When Is a Root Canal Needed?
When the Inside of a Tooth Is Compromised
Deep tooth decay
Repeated treatment on the same tooth
Repeated treatment on the same tooth
Trauma or injury
Another condition affecting the tooth nerve
Bacteria entering the internal tooth structure
Without treatment, inflammation or infection may progress and affect the bone and tissues surrounding the root.
Root canal therapy may allow the tooth to be preserved rather than removed.
Possible Signs
Symptoms That Deserve Attention
A tooth requiring root canal treatment does not always produce obvious symptoms. When symptoms are present, they may include:
Severe or persistent tooth pain
Lingering sensitivity to hot or cold
Drainage or an unpleasant taste
Pain when biting or chewing
A chipped or cracked tooth
A small bump on the gums
Pressure or throbbing
Pain that interrupts sleep
Facial swelling
These symptoms can have several causes. An examination is necessary to determine whether root canal therapy or another treatment is appropriate.
If swelling affects your breathing or swallowing, seek immediate emergency medical care.
Your Evaluation
Understanding the Source of the Problem
Tooth pain does not always come from the tooth that appears to hurt.
Discomfort can be referred from another tooth, the jaw, the gums, or surrounding structures. That is why careful diagnosis is essential before treatment begins.
Your evaluation may include:
01
A discussion of your symptoms
We will ask when the discomfort began, what it feels like, and what makes it better or worse.
02
A focused examination
Your doctor will evaluate the tooth, surrounding gums, nearby teeth, and your bite.
03
Diagnostic testing
We may assess the tooth’s response to temperature, pressure, tapping, or other carefully selected tests.
04
Digital imaging
X-rays help us evaluate the roots and surrounding bone. CBCT 3D imaging may be used in selected cases.
05
A review of treatment options
We will explain what we found and discuss whether the tooth can be predictably preserved.
What to Expect
A Carefully Managed Treatment Process
Root canal therapy may be completed in one or more visits depending on the tooth and the extent of the condition.
Your doctor will explain each stage before treatment begins and keep you informed throughout the appointment.
Treatment generally includes the following steps:
Step one
Keeping You Comfortable
The tooth and surrounding area are numbed with local anesthesia.
Step two
Isolating the Tooth
A protective sheet is placed around the tooth to keep it clean and dry during treatment.
Step three
Accessing the Inner Tooth
A small opening is created to reach the pulp chamber and root canals.
Step Four
Removing Compromised Tissue
Inflamed or infected tissue is carefully removed from inside the tooth.
Step Five
Cleaning and Shaping
The root canals are cleaned, disinfected, and shaped to receive the sealing material.
Step Six
Sealing the Canals
The prepared canals are filled with a specialized material to reduce the risk of contamination.
Step Seven
Protecting the Tooth
A temporary or permanent filling is placed to close the access opening.
Step Eight
Restoring the Tooth
A crown or another final restoration may be recommended to protect the tooth from future damage.
The discomfort associated with a root canal usually comes from the inflamed or infected tooth—not from the treatment itself.
Local anesthesia is used to help keep you comfortable during the procedure. You may feel pressure, vibration, or movement, but you should not feel sharp pain.
Please tell us if you feel uncomfortable at any point. We can pause, provide additional anesthesia when appropriate, and help you feel more at ease.
After treatment, temporary tenderness or sensitivity may occur as the surrounding tissues heal.
Your Comfort
Root Canal Treatment Is Designed to Relieve Pain
Restoring the Tooth
Root Canal Therapy Is Only Part of the Process
After the inside of the tooth has been treated, the remaining tooth structure must be protected.
Teeth requiring root canal therapy are often already weakened by decay, fractures, large fillings, or the access needed to complete treatment.
Back teeth are exposed to significant chewing pressure and may frequently require a crown. Front teeth may have different restorative needs.
Delaying the final restoration can leave the tooth vulnerable to fracture or contamination.
Depending on the location and condition of the tooth, the final restoration may be:
A tooth-colored filling
A dental crown
A crown supported by a foundation or core
Another restoration selected for the individual tooth
The area may remain numb for several hours after your appointment. Avoid chewing until normal sensation returns so you do not accidentally bite your cheek, lip, or tongue.
Temporary tenderness may occur for several days, especially if the tooth was painful or infected before treatment.
Follow the personalized instructions provided by your doctor, including guidance regarding:
After Treatment
Giving the Tooth Time to Settle
Eating and chewing
Temporary restorations
Recommended or prescribed medication
Brushing and flossing
Your follow-up appointment
Placement of the final restoration
Until the tooth has received its final restoration, avoid chewing hard or sticky foods on that side unless your doctor advises otherwise.
Contact Mandarin Dentistry if you experience:
- Severe pain or pressure that is not improving
- Increasing swelling
- Fever or feeling unwell
- Drainage or an unpleasant taste
- A temporary filling that comes out
- A tooth that feels too high when you bite
- Symptoms that return after improving
- A visible crack or fracture
- An allergic reaction to medication
- Another concern about the treated tooth
Prompt communication allows us to determine whether the tooth needs to be evaluated.
When to Contact Us
Do Not Ignore Unexpected Changes
Root Canal Therapy and Antibiotics
Treating the Source of the Problem
Antibiotics do not replace root canal treatment.
In many tooth-related infections, the compromised tissue inside the tooth has limited or no blood supply. An antibiotic may not adequately reach or eliminate the source of the problem.
Root canal therapy addresses the source by removing the inflamed or infected tissue, cleaning the internal spaces, and sealing the tooth.
Antibiotics may be prescribed when there are specific indications, such as spreading infection, fever, or other signs that the condition is affecting the body more broadly.
If antibiotics are prescribed, take them exactly as directed. Do not use leftover medication or someone else’s prescription.
Root Canal vs. Tooth Extraction
Preserving the Natural Tooth When Possible
When a tooth is infected or severely damaged, the two primary options may be root canal therapy or extraction.
Root Canal Therapy
Root canal treatment preserves the natural tooth. After it is restored, the tooth can continue contributing to your bite and smile.
Tooth Extraction
Extraction removes the tooth completely. Depending on its location, replacement with an implant, bridge, or removable prosthesis may be recommended.
Saving the tooth is not always possible or predictable. A severe fracture, inadequate remaining structure, advanced bone loss, or another concern may make removal the more responsible option.
We will explain the condition of the tooth, the expected outlook, and the alternatives before you decide.
Referral to an Endodontist
When Specialized Care May Be Recommended
Many root canals can be completed at Mandarin Dentistry. Some teeth, however, have complex anatomy or circumstances that benefit from care by an endodontist—a dentist who specializes in treating the inside of teeth.
If a referral is recommended, we will explain why and coordinate your restorative care after treatment.
Referral may be considered for:
Complex root anatomy
Previously treated teeth requiring retreatment
Difficult-to-locate canals
Significant calcification
Certain dental injuries
Persistent symptoms
Complications during treatment
Other circumstances requiring specialized equipment or expertise
Protecting the Tooth Long Term
Continued Care Still Matters
A root-canal-treated tooth can no longer respond to temperature in the same way, but it still requires consistent care.
The tooth remains connected to the surrounding gums and bone and can still develop:
- Decay around the restoration
- Gum disease
- Fractures
- Bite-related damage
- Problems with the crown or filling
- New infection
To protect the tooth:
- Complete the final restoration promptly.
- Brush twice a day with fluoride toothpaste.
- Clean between your teeth daily.
- Attend regular examinations and cleanings.
- Avoid chewing ice and other very hard objects.
- Wear a nightguard if recommended.
- Contact us if the tooth begins to feel different.
The cost of root canal therapy depends on:
- Which tooth requires treatment
- The number and complexity of its canals
- Whether emergency care is needed
- Whether referral to an endodontist is recommended
- The type of final restoration
- Whether additional treatment is necessary
Before moving forward, we will explain the recommended care and provide clear financial information.
If you have dental insurance, our team can check whether benefits may be available. Verification does not guarantee coverage or payment.
Financing may be available through CareCredit and Proceed Finance for qualified patients.

Frequently Asked Questions
Is a root canal painful?
Local anesthesia is used to help keep you comfortable. The procedure is intended to relieve the pain caused by an inflamed or infected tooth. Temporary tenderness may occur afterward.
How long does root canal treatment take?
Treatment may require one or more visits depending on the tooth, the number of canals, the severity of the condition, and whether additional care is needed.
Will I need a crown afterward?
Many root-canal-treated teeth—particularly back teeth—benefit from the protection of a crown. The recommendation depends on the tooth’s location and the amount of healthy structure remaining.
Can antibiotics cure an infected tooth?
Antibiotics may help manage certain spreading infections, but they generally do not remove the source inside the tooth. Root canal treatment or extraction is usually needed to address that source.
How long will the tooth last after treatment?
A properly treated and restored tooth can remain functional for many years, but no treatment can be guaranteed for life. Home care, restoration quality, bite forces, and regular monitoring influence longevity.
Can I drive after a root canal?
If only local anesthesia is used, many patients can drive afterward. If another medication or sedation is provided, you may need transportation. Follow the instructions given by your doctor.
