Your dentist has told you the tooth is badly infected, and you have a choice: save it with root canal treatment (RCT), or remove it entirely with a tooth extraction. Both are common. Both are safe. But they lead to very different outcomes: financially, physically, and for your long-term oral health.
This guide lays out every meaningful comparison side by side so you can walk into your dental appointment with confidence, not confusion.
The Full Breakdown at a Glance
| Factor | Root Canal Treatment | Tooth Extraction |
| What it does | Removes infection, seals, and saves the natural tooth | Removes the tooth entirely from the jaw |
| Number of visits | 1–3 appointments | Usually 1 (+ follow-up consultation) |
| Pain during procedure | None, full local anaesthetic | None, full local anaesthetic Equal |
| Recovery time | 1–3 days mild soreness | 3–7 days; longer for surgical cases |
| Jawbone preserved? | Yes, root stimulates bone naturally | No, bone shrinks over time without a root |
| Neighbouring teeth affected? | No, bite stays balanced | Adjacent teeth drift into the gap over time |
| Longevity | Can last a lifetime with proper care | Implant replacement can last 20+ years if placed |
| Crown needed after? | Usually yes for back teeth (additional cost) | No crown, but replacement recommended |
| Suitable when the tooth is… | Infected but structurally intact | Severely fractured, non-restorable, or failed RCT |
| Best long-term outcome | Yes | Acceptable if replaced with an implant promptly |
| Upfront cost (AU) | $1,000–$2,500+ (tooth type dependent) | $150–$600 simple; $300–$600 surgical |
| True long-term cost | Often more affordable over a lifetime | Higher; replacement implant adds $3,000–$6,500 |
Root Canal Treatment Cost vs Tooth Extraction Cost in Australia
Root Canal Treatment
Front tooth (1 canal) $1,000–$1,500
Premolar (1–2 canals) $1,200–$1,800
Molar (3–4 canals) $1,500–$2,500+
Dental crown (if needed) $1,500–$2,000
Estimated total ~$2,500–$4,500
The tooth is preserved indefinitely after a one-time cost. Many health funds contribute toward RCT under major dental cover.
Tooth Extraction + Replacement
Simple extraction $150–$400
Surgical extraction $300–$600
Dental implant (replacement option) $3,000–$6,500
Dental bridge (alternative option) $2,500–$4,500
Estimated total $3,150–$7,100+
Low upfront cost but high replacement cost. Skipping replacement can cause bone loss, bite shift, and further dental costs.
The hidden truth about “cheaper” extraction: Removing a tooth without replacing it isn’t a saving; it’s a debt. Bone loss begins within months, neighbouring teeth shift, and your risk of needing further dental work increases significantly. When you factor in the cost of extraction + replacement, root canal treatment often costs less over a lifetime.
How Long Does Each Option Last?
Here’s what the evidence shows for each treatment path over time, when properly maintained with regular dental check up and clean appointments.
Root Canal + Crown 10–40+ yrs
Root Canal (no crown) 5–15 yrs
Extraction + Implant 15–25+ yrs
Extraction + Bridge 10–15 yrs
Extraction, no replacement Not advised
These figures reflect the average outcomes. Individual results can vary depending on your oral hygiene, tooth location, and restoration quality.
What Happens to Your Mouth After Each Option?
Bone Preservation
After RCT, the natural root stays in the jawbone, maintaining density and volume. Extraction leads to bone resorption within 3–6 months.
Bite Alignment
RCT allows neighbouring teeth stay in position. After extraction, adjacent and opposing teeth drift and tip into the gap.
Chewing Function
Full chewing function restored with a crown after RCT. Extraction without replacement reduces chewing efficiency significantly.
Aesthetics
With RCT, natural tooth appearance is maintained. Extraction leaves a visible gap, especially concerning the front teeth.
Speed of Resolution
One Extraction appointment resolves the immediate problem. RCT may require multiple visits, especially for complex infections.
Invasiveness
Extraction is simpler initially, but replacing the tooth later with an implant is a surgical procedure, making the total journey more invasive.
Overall Oral Health Verdict
RCT delivers superior long-term oral health outcomes in almost every category, especially when followed by a crown and maintained with good hygiene. Extraction is the right call only when the tooth genuinely cannot be saved.
What to Expect After Each Procedure
Root canal treatment side effects are often milder than people expect. Here’s an honest comparison of what recovery actually looks like.
After Root Canal Treatment
- Mild soreness when biting (1–3 days)
- Gum tenderness around the treated area
- Slight sensitivity — managed with paracetamol/ibuprofen
- Return to normal activities within 24–48 hours
- Temporary swelling or residual infection is rare
- No dietary restrictions beyond a few days of soft food
After Tooth Extraction
- Bleeding from socket (first few hours)
- Swelling and bruising — often peaks at day 2–3
- Pain managed with prescribed or OTC medication
- Diet restricted to soft foods for 3–7 days
- Risk of dry socket (3–4%) — painful if it occurs
- Longer recovery for surgical or impacted extractions
Wisdom teeth are different: If the extraction involves wisdom teeth, recovery is typically more involved. Check our guide on wisdom teeth removal cost and recovery for a full picture.
Which Option Is Right for You?
The right choice depends on the actual condition of your tooth. Use this guide to understand where your situation likely fits, then confirm with your dentist.
Your Situation → Likely Recommendation
Tooth is infected but structurally intact → Root Canal Treatment
Deep decay near or into the pulp → Root Canal Treatment
Tooth cracked but roots still healthy → Root Canal + Crown
Tooth fractured below the gumline → Extraction Required
Severe bone loss around the tooth → Likely Extraction
Previous root canal has failed → Discuss Retreatment vs Extraction
Abscess or severe swelling (urgent) → See an Emergency Dentist Today
