Your child needs a pulpotomy—a root canal on a baby tooth. Your first thought: why save a tooth that's going to fall out anyway?
The answer is simple but important: saving that baby tooth prevents far worse problems down the road.
What a Pulpotomy Actually Is
A pulpotomy is a simplified root canal procedure. When decay reaches the nerve (pulp) of a baby tooth, the pulp becomes infected and painful. A pulpotomy removes the infected pulp tissue, leaving behind the root structure.
It's different from adult root canals, which remove entire pulp and fill the whole canal. Pulpotomy just removes the chamber pulp (the infected part), leaving the root structures largely intact.
The goal: save the tooth, eliminate pain/infection, and keep it in place until it naturally sheds.
Baby Tooth Pulpotomy vs. Extraction
| Aspect | Pulpotomy (Save Tooth) | Extraction (Pull Tooth) |
|---|---|---|
| Cost | $150-300 per tooth | $75-150 per tooth |
| Procedure time | 15-30 minutes | 5-10 minutes |
| Anesthesia | Usually yes (numbing sufficient) | Usually yes |
| Recovery | Minimal; 1-2 hours of sensitivity | Bleeding for few minutes; socket tender |
| Space preservation | Tooth stays; natural space holder | Baby tooth gone; space lost to drift |
| Permanent tooth effect | Helps permanent tooth erupt correctly | Can cause crowding, misalignment, space loss |
| Need for space maintainer | No; tooth is there | Usually yes; expensive device needed |
| Chewing function | Preserved; child can chew on both sides | One less tooth; harder chewing |
| Nutritional impact | Normal eating maintained | Can affect nutrition if multiple extractions |
| Speech | Preserved | May affect if multiple losses |
| Infection risk after | Minimal; tooth is sealed | Very low; socket is open but cleanses quickly |
| Success rate | 90%+ if properly treated | 100% (procedure always successful) |
| Overall cost | Pulpotomy + restore tooth + future monitoring | Extraction + space maintainer ($200-400) = often MORE expensive |
Why Baby Teeth Matter (They're Not Just "Going to Fall Out")
Baby teeth are critical:
Space holding: Baby molars hold space for permanent premolars. Extracting a baby molar leads to permanent tooth crowding when the permanent tooth erupts years later.
Guiding eruption: Baby teeth guide permanent teeth into correct positions. Early loss disrupts this guidance.
Nutrition: Molars enable proper chewing. Losing molars affects ability to chew nutritious foods.
Speech: Teeth are involved in speech production. Multiple losses can affect speech development.
Self-esteem: Visible missing teeth affect children's confidence, especially if multiple teeth.
Bone development: Baby teeth stimulate jaw bone development. Multiple extractions can affect jaw growth.
Cost: Space maintainers (needed after extraction) cost $200-400 per tooth. A pulpotomy ($150-300) plus restoration is often cheaper than extraction plus maintainer.
Early extraction of infected baby teeth often creates more problems than the original infection.
When Pulpotomy Is Indicated
Clear cases for pulpotomy: - Deep decay that's infected the nerve - Pain in the tooth (obvious nerve involvement) - Swelling or abscess around tooth - Tooth still has 2+ years before natural shedding - Tooth is important for space holding (molars especially) - Extraction would require space maintainer
Cases where extraction might be considered: - Tooth is already very loose (shedding naturally soon) - Multiple problematic baby teeth (cost/benefit shifts) - Severe infection that won't respond to treatment - Tooth almost ready to shed naturally anyway
Most infected baby teeth benefit from pulpotomy, not extraction.
The Pulpotomy Procedure: What to Expect
Before: - X-ray to confirm nerve involvement and assess roots - Local anesthesia (numbing) - Rubber dam isolation (keeps tooth dry)
During: 1. Remove decay from tooth 2. Access the pulp chamber (top part of tooth) 3. Remove infected pulp tissue from chamber 4. Cauterize to seal the opening 5. Fill chamber with medicated paste 6. Restore tooth with filling material (usually resin or amalgam)
Time: Usually 15-30 minutes
After: - Tooth remains in place - Numbness wears off in 1-2 hours - Minimal sensitivity (treatable with ibuprofen if needed) - Child can eat soft foods after numbness wears off - Tooth functions normally (with filling in place)
Success Rate and Complications
Success rate: 90%+ for properly treated baby teeth. The tooth stays healthy, serves its purpose, and sheds naturally on schedule.
Potential issues: - Restoration fails (filling comes loose): Needs replacement. Fairly common with baby teeth; not serious. - Tooth becomes tender (rare): Usually resolves; may need extraction if persistent. - Abscess returns (rare if well-treated): Usually indicates need for extraction instead. - Root resorption (normal): Baby tooth root naturally resorbs as permanent tooth develops; expected process.
Most pulpotomies are successful, and the tooth remains functional until it naturally sheds.
Care After Pulpotomy
Immediate after: - Avoid hard/crunchy foods for 24 hours - Soft diet while sensitive - Normal brushing once numbness wears off
Ongoing: - Normal brushing and flossing - Regular dental checkups - Avoid excessive force on tooth (don't let child crack on it) - Monitor for any pain or swelling
If restoration is lost: - See dentist soon to recheck tooth - May need new restoration or retreat - Not an emergency unless tooth is painful
Cost-Effectiveness Reality
Pulpotomy cost: $150-300
Restoration (filling/crown): $50-150
Total pulpotomy treatment: $200-450
Extraction cost: $75-150
Space maintainer cost (needed after extraction): $200-400
Total for extraction + maintainer: $275-550
Plus: If space loss causes crowding, future orthodontics could cost thousands.
Financially: Pulpotomy is often equal or cheaper than extraction-plus-maintainer route, especially long-term.
Special Considerations for Different Teeth
Front teeth (incisors): - Less critical for space holding - Esthetically important - Pulpotomy is good choice to maintain appearance - Extraction is less problematic than back teeth
Baby molars (most critical): - Absolutely need space maintenance - If extracted, space maintainer is essential - Pulpotomy is strongly recommended - Saving molar prevents future crowding
Canines: - Important for guiding permanent teeth - Extraction can affect alignment - Pulpotomy is generally better choice
When to Get a Second Opinion
Ask another pediatric dentist if: - Your dentist recommends extracting multiple baby teeth - Pulpotomy is recommended but costs seem very high - You're unsure whether treatment is necessary - Extraction is recommended as first choice instead of saving tooth
Most pediatric dentists recommend saving baby teeth when infection can be treated. Getting consensus is reasonable.
Questions to Ask Your Dentist
- "Is this tooth's nerve infected? How do you know?"
- "How much longer will this baby tooth be here?"
- "What happens if we don't treat it?"
- "What's the success rate for pulpotomy on this tooth?"
- "What's the cost, and is it covered by insurance?"
- "What happens if the pulpotomy doesn't work?"
- "Would extraction and space maintainer be cheaper long-term?"
- "How often do I need to see you to monitor it?"
A good pediatric dentist explains the reasoning clearly and discusses both options (pulpotomy vs. extraction).
Aftercare Monitoring
After pulpotomy, your dentist will: - Schedule follow-up visit 2-4 weeks after treatment - Check that restoration is intact - Assess for any sensitivity or problems - Monitor the tooth until it naturally sheds
Most teeth shed naturally on schedule without complications. Occasional X-rays confirm no root problems developing.
The Bottom Line
A baby tooth with infected nerve needs treatment to eliminate infection and pain. Pulpotomy is the preferred choice for most baby teeth because it:
- Saves the tooth and its function
- Preserves space for permanent teeth
- Prevents future crowding
- Maintains nutrition and chewing
- Often costs the same or less than extraction-plus-maintainer
Yes, the baby tooth will eventually shed. But premature extraction creates problems (crowding, space loss, alignment issues) that cost far more to fix later.
Save the tooth when it can be saved. Your child's adult teeth will thank you.
Your pediatric dentist will recommend pulpotomy when it's the right choice. Trust their judgment—they see hundreds of these cases and understand the long-term implications of extraction versus saving.
