Root Canal Therapy
Root canal therapy treats inflamed or infected tissue inside a tooth to relieve symptoms, control infection, and help preserve the natural tooth whenever possible.
At a glance
A quick overview before exploring the treatment in greater detail.
Treats inflamed or infected tissue inside the tooth
May relieve pain, pressure, and lingering sensitivity
Helps preserve a natural tooth that might otherwise require extraction
Understanding root canal therapy
Inside each tooth is a chamber containing soft tissue called dental pulp. The pulp includes nerves, blood vessels, and connective tissue that help support the tooth during development.
Deep decay, cracks, trauma, repeated dental treatment, or a leaking restoration can allow the pulp to become inflamed or infected. When the pulp cannot recover, root canal therapy may be recommended.
During treatment, the damaged tissue is removed, the internal canals are cleaned and shaped, and the space is sealed to reduce the risk of continued infection. The tooth is then restored to protect it and return it to function.
At Prestwicke Dental, we evaluate the symptoms, remaining tooth structure, periodontal support, bite, diagnostic imaging, and long-term restorability before recommending root canal therapy.
Why patients consider this treatment
Potential benefits depend on your diagnosis, treatment goals, and individual oral health.
Addresses infection or inflammation inside the tooth
May relieve severe or persistent tooth pain
Helps preserve the natural tooth
Reduces the risk of infection spreading
Restores more comfortable chewing and biting
Allows the tooth to be rebuilt for long-term function
What to expect
A clear process helps you understand each stage of care.
Evaluation
We review your symptoms, examine the tooth, test its response, and use diagnostic imaging when appropriate.
Comfort and Isolation
The area is numbed, and the tooth is isolated to keep the treatment field clean and controlled.
Cleaning the Canals
The inflamed or infected tissue is removed, and the internal canals are carefully cleaned, shaped, and disinfected.
Sealing and Restoration
The canals are sealed, and the tooth is restored. A crown may be recommended to protect weakened structure.
How we approach root canal therapy
Treatment recommendations depend on the diagnosis and condition of the affected teeth and tissues.
Not every toothache requires root canal therapy. Sensitivity, bite pain, gum problems, cracks, sinus pressure, and other conditions can produce similar symptoms. A careful examination is necessary to determine the cause.
During treatment, an opening is created in the tooth to access the pulp chamber and root canals. The affected tissue is removed, and the canals are cleaned, shaped, disinfected, and sealed.
Some cases can be completed in one appointment, while others may require additional visits depending on the anatomy, infection, symptoms, and treatment complexity.
A temporary restoration may be placed until the tooth receives its final restoration. Many back teeth require a crown because they may be weakened by decay, cracks, large fillings, or loss of tooth structure.
Temporary tenderness after treatment can occur as the surrounding tissues heal. Contact the office if pain or swelling increases, the bite feels high, or the temporary restoration becomes loose.
If a tooth has a severe vertical fracture, inadequate bone support, extensive structural loss, or another poor prognostic factor, extraction may be more appropriate than root canal therapy.
Is this treatment right for you?
Root canal therapy may be appropriate when the pulp inside a tooth is irreversibly inflamed, infected, or damaged and the tooth can still be predictably restored.
You have severe, spontaneous, or persistent tooth pain.
Sensitivity to hot or cold lingers after the stimulus is removed.
You feel pain when biting or chewing.
There is swelling, tenderness, or drainage near a tooth.
A tooth has deep decay, a large restoration, a crack, or previous trauma.
The tooth has enough remaining structure and support to be restored.
What results may look like
Root canal therapy may relieve symptoms, control infection, and preserve a natural tooth for continued function. Long-term success depends on the condition of the tooth, quality of the final restoration, bite forces, oral hygiene, and routine dental care.
Individual outcomes vary based on oral health, diagnosis, treatment selection, healing, habits, and maintenance.
Care centered on clarity, comfort, and long-term health
Every treatment plan is personalized around the patient rather than a one-size-fits-all approach.

Common questions about root canal therapy
These answers provide general information. Your visit will address your specific oral health and treatment needs.
Does a root canal hurt?
Local anesthesia is used during treatment. Many patients find the procedure more comfortable than expected, especially once pressure from inflammation or infection is addressed.
How do I know whether I need a root canal?
Possible signs include lingering temperature sensitivity, severe tooth pain, pain when biting, swelling, drainage, or discoloration. Some affected teeth cause few symptoms, so an examination and imaging may be needed.
How long does root canal treatment take?
The length of treatment depends on the tooth, number of canals, anatomy, infection, and complexity. Some cases are completed in one visit, while others require additional appointments.
Will I need a crown after a root canal?
Many back teeth need crowns because they often have substantial structural loss. The recommendation depends on the tooth location, remaining structure, bite, and existing restorations.
Can every infected tooth be saved?
No. A tooth may not be restorable if it has a severe fracture, inadequate periodontal support, extensive decay, or insufficient remaining structure.
What happens if I delay root canal treatment?
Symptoms may worsen, infection may spread, and the tooth may become more difficult or impossible to save. The exact risk depends on the diagnosis and condition of the tooth.
Can a tooth need another root canal later?
Yes. Retreatment may be needed if infection persists or returns because of complex anatomy, leakage, new decay, fracture, or another problem.
How long can a root canal-treated tooth last?
A successfully treated and properly restored tooth may function for many years. Longevity depends on the original condition, final restoration, bite forces, oral hygiene, and ongoing care.
Can I drive after root canal therapy?
Most patients can drive after treatment when only local anesthesia is used. If sedation is provided, transportation arrangements may be required.
What should I eat after treatment?
Avoid chewing hard or sticky foods on the treated tooth until the permanent restoration is completed, especially while a temporary filling or crown is present.
