You've ignored that dark spot on your back molar for two years. Now it's painful, and your dentist says the decay is deep. You're facing a decision: root canal treatment to save the tooth, or extraction and replacement. How do you choose? Here's the complete guide.
Understanding "Advanced Decay"
Tooth decay progresses in stages:
- Initial decay (enamel only): No pain, reversible with fluoride — cost: ₹0-₹500
- Moderate decay (reaches dentin): Mild sensitivity, needs filling — cost: ₹1,500-₹3,000
- Deep decay (near nerve): Pain when eating, may need deep filling or RCT — cost: ₹3,000-₹8,000
- Advanced decay (nerve involved): Severe pain, infection, abscess — needs RCT or extraction — cost: ₹8,000-₹15,000
- Severe structural loss: Tooth mostly destroyed — often requires extraction — cost: ₹1,500-₹3,000 + replacement
The earlier you catch decay, the simpler and cheaper the treatment. Advanced decay forces tough decisions.
Root Canal Treatment (RCT): Saving Your Natural Tooth
What is RCT?
Root canal treatment removes the infected nerve and blood vessels inside your tooth, cleans and disinfects the root canals, and seals them to prevent reinfection. The tooth remains in your mouth — alive structurally, but no longer sensitive.
When RCT Is Recommended:
- Deep decay reaching the nerve, but tooth structure is mostly intact
- Tooth is important for chewing function
- You're willing to invest in a crown afterward (necessary for long-term success)
- The tooth has adequate bone support
- No severe infection or cyst that can't be treated
RCT Cost in Chennai:
- Front tooth: ₹3,000-₹5,000
- Premolar: ₹4,000-₹7,000
- Molar: ₹6,000-₹10,000
- Crown (required): ₹8,000-₹15,000
- Total: ₹11,000-₹25,000
Benefits of Saving Your Tooth:
- Preserves natural tooth structure: Nothing functions as well as your natural tooth
- Prevents bone loss: Tooth roots stimulate jawbone, maintaining its strength
- Prevents neighboring teeth from shifting: Extraction creates gaps that cause misalignment
- Better chewing efficiency: Natural teeth sense pressure better than replacements
- More cost-effective long-term: One RCT + crown can last 15-20 years, while extraction leads to expensive replacement needs
Tooth Extraction: When It's the Better Choice
When Extraction Is Recommended:
- Severe structural loss: Less than 30% of natural tooth structure remains — not enough to support a crown
- Vertical root fracture: Tooth is cracked from top to root — can't be repaired
- Advanced gum disease: Severe bone loss around the tooth makes it too unstable
- Poor long-term prognosis: Even with RCT, the tooth is unlikely to last more than 2-3 years
- Economic constraints: You can't afford RCT + crown but can manage extraction + partial denture
- Wisdom teeth: If it's a problematic wisdom tooth with no functional role, extraction is often best
Extraction Cost + Replacement:
- Extraction: ₹1,500-₹3,000
- Dental implant (best replacement): ₹30,000-₹50,000
- Dental bridge: ₹15,000-₹25,000
- Partial denture: ₹8,000-₹15,000
Note: Extraction is cheap, but replacement is expensive. Total cost: ₹9,500-₹53,000
The Decision-Making Process
Your dentist evaluates:
- Clinical examination: How much tooth structure remains?
- X-rays: How deep is the decay? Is bone loss present? Are roots fractured?
- Periodontal probe: How healthy are the gums?
- Your age and health: Younger patients benefit more from saving teeth
- Your budget and priorities: Can you invest in RCT + crown?
The Chennai Reality: False Economy
Many Chennai patients choose extraction because it's cheaper upfront (₹2,000 vs ₹15,000 for RCT + crown). But they don't realize:
- Neighboring teeth shift, causing bite problems
- Bone gradually shrinks in the gap
- Chewing efficiency decreases, affecting digestion
- Eventually, they need an implant (₹40,000) or bridge (₹20,000) anyway
Result: What seemed like a ₹13,000 savings becomes a ₹25,000 expense later — plus the inconvenience of losing a tooth.
What If You Choose Extraction?
If extraction is necessary or chosen, replace the tooth promptly:
- Don't delay: Waiting causes bone loss and makes implants harder/costlier
- Consider implants first: Most durable and natural-looking option
- Bridges are good alternatives: Faster and less expensive than implants
- Dentures are last resort: Least expensive but least comfortable
Dr. Mani Sundar's Treatment Philosophy: "I always try to save natural teeth first. If your tooth has 50% or more structure remaining and healthy bone support, RCT + crown is worth it. I've seen root canal-treated teeth last 20+ years — that's excellent value. But if the tooth is structurally compromised or has a vertical fracture, extraction is the honest recommendation. I'll never sell you a root canal that will fail in 3 years. Trust me to tell you the truth — not just what's profitable."
