The Procedure That Saves Teeth Most People Think Are Lost
Root canal treatment has a reputation problem. Most people associate it with pain. In practice, it's the treatment that stops the pain.
If your dentist has recommended a root canal, or you're researching because a tooth has been bothering you, this guide covers the procedure step by step, what to expect for discomfort, and how recovery works.
What a Root Canal Treats
Inside every tooth is a chamber of soft tissue called the pulp. It contains nerves, blood vessels, and connective tissue. During tooth development, the pulp is essential. In a fully formed adult tooth, it's not. The tooth can survive without it.
A root canal becomes necessary when the pulp is infected or irreversibly inflamed. Common causes include:
- Deep decay that has reached the pulp chamber.
- Cracks or fractures that allow bacteria inside the tooth.
- Repeated dental procedures on the same tooth causing cumulative trauma.
- Trauma or injury to the tooth, even if there's no visible crack.
Without treatment, an infected pulp can lead to an abscess, bone loss around the root, and spreading infection. A root canal removes the infected tissue and seals the tooth to prevent reinfection.
The Step-by-Step Process
Root canal treatment typically takes one or two appointments, each lasting 60 to 90 minutes depending on the tooth. Front teeth with a single canal are faster. Molars with three or four canals take longer.
1. Diagnosis and X-rays. Your dentist takes digital X-rays to see the shape of the root canals and the extent of infection. Sometimes a vitality test (a cold stimulus applied to the tooth) helps confirm the diagnosis.
2. Local anaesthetic. The tooth and surrounding area are numbed thoroughly. This is the same anaesthetic used for fillings. You should feel pressure but not pain during the procedure.
3. Isolation with a rubber dam. A small rubber sheet is placed around the tooth to keep it dry and free from saliva during treatment. It also prevents debris from entering your throat.
4. Access opening. Your dentist creates a small opening in the top of the tooth to reach the pulp chamber.
5. Cleaning and shaping. Using fine, flexible instruments, the infected pulp tissue is removed from the chamber and each root canal. The canals are shaped and flushed with antimicrobial solution to eliminate bacteria.
6. Filling the canals. Once clean and dry, the canals are filled with a biocompatible rubber material called gutta-percha. This seals the space to prevent bacteria from re-entering.
7. Temporary or permanent restoration. A temporary filling may be placed if a second visit is needed. In most cases, the tooth will require a dental crown afterwards to protect it from fracture, since root-treated teeth become more brittle over time.
Does It Hurt?
This is the question everyone asks. The honest answer: modern root canal treatment is comparable to having a filling done.
Local anaesthetic is effective. The procedure itself should not be painful. You'll feel vibration and pressure from the instruments, but not sharp pain. If you feel anything beyond pressure at any point, more anaesthetic can be given.
The discomfort that brings people to the dentist, the throbbing toothache, the sensitivity to hot drinks, the pain that wakes you at night, that's the infection. The root canal is what stops it.
After the procedure, mild soreness around the tooth is normal for a few days. Over-the-counter pain relief (ibuprofen or paracetamol) manages this well for most people.
If you're experiencing severe tooth pain right now, book an emergency appointment in Everton Park or Nundah online at any time. During opening hours, call for phone triage and booking help. Timing depends on clinical urgency and clinic capacity.
Recovery: What to Expect
Most people return to normal activities the day after treatment. Here's the typical timeline:
- Day 1 to 3. Mild tenderness when biting on the tooth. This is normal inflammation from the procedure, not a sign of failure.
- Day 3 to 7. Tenderness fades. Most discomfort has resolved.
- Week 2 onwards. The tooth should feel normal. If it doesn't, contact your dentist.
During recovery:
- Avoid chewing hard foods on the treated tooth until the permanent crown is placed.
- Take prescribed or recommended pain relief as directed.
- Continue brushing and flossing normally. Don't avoid the area.
- Attend your follow-up appointment for the crown. An uncrowned root-treated tooth is vulnerable to fracture.
Book a general dentistry consultation if you have a tooth that's been causing persistent pain or sensitivity.
Success Rates and Longevity
Root canal treatment has a high success rate. Published research indicates success rates typically fall between 85% and 95%, depending on the tooth, the extent of infection, and the quality of the final restoration.
A root-treated tooth with a well-fitted crown can last decades. Some last a lifetime. Factors that influence longevity include:
- Crown quality. A tooth without a crown after root canal treatment is significantly more likely to fracture.
- Oral hygiene. Root-treated teeth can still develop new decay around the crown margins.
- Complexity of the original infection. Teeth with severe infections or unusual canal anatomy may have a slightly lower success rate.
In a small percentage of cases, retreatment may be needed if infection recurs. Your dentist will discuss this possibility based on your specific situation.
Alternatives to Root Canal Treatment
If root canal treatment is recommended, the main alternative is extraction. Leaving an infected tooth untreated is not a safe option as the infection can spread.
After extraction, you'd need to consider replacing the missing tooth with an implant, bridge, or denture. Each of those options involves additional treatment, time, and cost.
In most cases, saving the natural tooth with a root canal is the preferred approach. Your own tooth, even with the pulp removed, functions better than any replacement.
There are situations where extraction is the better option. Teeth with severe fractures extending below the gum line, teeth with very little remaining structure, or teeth with poor long-term prognosis may be better extracted. Your dentist will give you a clear recommendation based on your X-rays and clinical findings.
Cost
Root canal treatment cost varies with the tooth. Front teeth with a single canal cost less than molars with multiple canals. For detailed pricing information, see our root canal cost guide.
A crown is usually recommended after root canal treatment. Crowns start from $1,600 at Ivy Dental. Your total investment includes the root canal treatment, any posts or build-ups needed, and the crown.
Health fund rebates apply to root canal treatment under most major funds. We process claims on the spot with HICAPS at our Everton Park and Nundah locations.
When to See a Dentist
Don't wait for severe pain. See your dentist if you notice:
- A toothache that lingers after eating or drinking hot or cold foods.
- Pain that wakes you at night.
- A pimple or swelling on the gum near a tooth.
- Darkening of a tooth.
- Prolonged sensitivity that doesn't resolve.
Early treatment often means a simpler procedure and a better outcome.
