A persistent toothache, sensitivity to hot or cold foods, or swelling around a tooth can sometimes indicate a problem involving the dental pulp — the soft tissue containing nerves and blood vessels inside the tooth. When the pulp becomes inflamed or infected, root canal treatment may be recommended to remove the affected tissue and retain the natural tooth.
Can an infected tooth be saved? In many cases, yes. Root canal treatment may help preserve a natural tooth affected by infection or inflammation, depending on its condition.
At CQ Dental Studio in Rockhampton, we assess patients experiencing dental pain and infection and discuss appropriate treatment options, including root canal treatment where suitable.
What Is Root Canal Treatment?
Root canal treatment, also called endodontic treatment, is a dental procedure used to treat inflammation or infection within the pulp of a tooth.
The pulp is located inside the tooth and extends through narrow channels called root canals.
When the pulp becomes irreversibly inflamed or infected, it generally cannot recover without treatment.
Root canal treatment involves removing the affected pulp, cleaning and disinfecting the root canal system, and sealing the canals to reduce the risk of further infection.
The aim is to retain the natural tooth rather than remove it.
Why Would a Tooth Need Root Canal Treatment?
There are several reasons why the pulp inside a tooth may become damaged or infected.
Deep Tooth Decay
When decay progresses through the outer layers of a tooth, bacteria may eventually reach the pulp.
Cracked or Fractured Teeth
Cracks can allow bacteria to enter deeper parts of the tooth or directly damage the pulp.
Dental Trauma
An injury to a tooth can damage its blood supply, sometimes leading to pulp deterioration even when the tooth appears intact.
Repeated Dental Treatment
A tooth that has undergone extensive restorative treatment may occasionally develop pulp inflammation or infection.
Not every painful tooth requires root canal treatment. A clinical examination and appropriate investigations are necessary to establish the cause.
What Are the Signs of an Infected Tooth?
Symptoms can vary considerably.
Possible signs include:
- Persistent or spontaneous toothache
- Pain when biting or chewing
- Prolonged sensitivity to hot or cold
- Swelling around the affected tooth
- A small pimple-like swelling on the gum
- Tenderness around the tooth
- Discolouration following dental trauma
Importantly, some infected teeth cause little or no pain.
An infection may occasionally be identified during a routine dental examination or on an X-ray.
What Happens During Root Canal Treatment?
The procedure depends on the tooth’s anatomy, the extent of infection and the complexity of the case.
Step 1: Examination and Diagnosis
Your dentist will examine the tooth and may perform sensitivity tests, percussion tests and dental X-rays.
These investigations help determine whether the pulp is affected and whether the tooth can be predictably restored.
Step 2: Local Anaesthetic
Local anaesthetic is generally administered to help manage discomfort during treatment.
Step 3: Accessing the Root Canals
An opening is created in the tooth to access the pulp chamber and root canals.
A rubber dam is usually placed to isolate the tooth and help maintain a clean treatment environment.
Step 4: Cleaning and Disinfecting
The affected pulp tissue is removed, and the root canals are carefully cleaned, shaped and irrigated.
Depending on the circumstances, medication may be placed inside the tooth between appointments.
Step 5: Filling the Root Canals
Once the canals are appropriately prepared, they are filled and sealed using suitable dental materials.
Step 6: Restoring the Tooth
After root canal treatment, the tooth requires an appropriate final restoration.
Some teeth can be restored with a filling, while others may benefit from a crown, particularly where substantial tooth structure has been lost.
Is Root Canal Treatment Painful?
Modern root canal treatment is generally performed using local anaesthesia and minimal pain.
Patients may experience pressure or other sensations during the procedure, and some tenderness can occur afterwards.
The level of discomfort varies depending on the condition of the tooth and surrounding tissues.
Your dentist can discuss pain management and what to expect during recovery.
Root Canal Treatment or Tooth Extraction?
When a tooth is severely damaged or infected, the two main treatment options may be root canal treatment or extraction.
Root Canal Treatment
Potential advantages include:
- Retaining the natural tooth
- Maintaining chewing function
- Avoiding an immediate gap
- Reducing the need for tooth replacement
However, root canal treatment is not always successful, and some teeth may require further treatment or extraction in the future.
Tooth Extraction
Extraction may be recommended where a tooth cannot be predictably restored, has a significant fracture or has insufficient supporting bone.
After extraction, replacement options may include a dental implant, bridge or denture.
The most suitable approach depends on the tooth’s condition, your overall oral health and your preferences.
Does Every Root Canal Treated Tooth Need a Crown?
Not necessarily.
The need for a crown depends on several factors, including:
- Which tooth has been treated
- How much natural tooth structure remains
- The size of existing restorations
- The presence of cracks
- The forces placed on the tooth
Back teeth often experience substantial chewing forces and may benefit from cuspal coverage following root canal treatment.
At CQ Dental Studio, we offer restorative options including same day ceramic crowns for suitable cases.
Can an Infected Tooth Heal with Antibiotics Alone?
Antibiotics do not generally eliminate an infection located inside a tooth with a necrotic pulp.
Definitive dental treatment, such as root canal treatment or extraction, is usually required to address the source.
Antibiotics may be indicated in selected circumstances, particularly when there are signs of spreading infection or systemic involvement.
They should not be considered a substitute for appropriate dental treatment.
When Is an Endodontist Referral Needed?
Some root canal treatments are more complex than others.
Factors such as unusual root anatomy, calcified canals, previous root canal treatment, difficult access or persistent infection may make specialist assessment appropriate.
An endodontist is a dentist who has completed additional specialist training in diagnosing and treating conditions affecting the dental pulp and surrounding tissues.
At CQ Dental Studio, we assess the complexity of each case and can recommend referral to an endodontist when appropriate.
Frequently Asked Questions
1. How long does root canal treatment take?
Treatment may require one or more appointments, depending on the tooth, its anatomy and the extent of infection.
2. Can a root canal treated tooth become infected again?
Yes. Although treatment aims to eliminate infection and seal the canals, reinfection or persistent infection can occur.
3. How long does a root canal treated tooth last?
Many root canal treated teeth remain functional for years, but longevity depends on the tooth’s condition, the quality of the final restoration and ongoing dental maintenance.
4. What happens if I leave an infected tooth untreated?
An untreated dental infection may persist, worsen or spread to surrounding tissues. Some infections can become serious and require urgent medical attention.
5. Can I have root canal treatment if my tooth doesn’t hurt?
Yes. Some teeth with infected or necrotic pulps produce few symptoms. Treatment decisions are based on clinical findings and investigations, not pain alone.
