Yes, though it’s called pulp therapy rather than a root canal. When decay or injury reaches the nerve inside a baby tooth, the infected tissue is removed and the tooth is sealed and usually crowned.
It’s a common treatment and far less dramatic than it sounds. Parents often assume pulling the tooth is simpler, and sometimes it is, but baby molars hold space for adult teeth until around age 12. A family dentist in Barrie weighs that before recommending either.
The question that really matters is what happens to the adult tooth underneath.
Infection at the root of a baby tooth sits directly above the developing permanent tooth and can affect how its enamel forms. Treating it properly, whether through pulp therapy or extraction, protects what’s coming next. Keeping decay away in the first place is what dental sealants and regular checkups are for.
Why not just pull it?
Because baby molars are placeholders, and losing one early causes problems that show up years later.
When a baby molar comes out before its time, the teeth behind it drift forward into the gap. The adult tooth that was meant to arrive there finds less room than it needs, which produces crowding or an impacted tooth.
Fixing that later means a space maintainer at best, or orthodontic treatment at worst. Keeping the natural tooth until it falls out on schedule avoids the whole sequence.
There are also practical reasons. Children chew better with a full set, speech develops around the teeth they have, and a gap in the smile line matters to a 7-year-old more than adults expect.
The two types of pulp therapy
Which one depends on how much of the nerve tissue is affected.
A pulpotomy removes only the infected pulp in the crown of the tooth, leaving the healthy tissue in the roots. This is the common one, often described to parents as a baby root canal. It takes one visit.
A pulpectomy removes the pulp from the roots as well, when infection has spread further. The canals are filled with a material that dissolves as the root resorbs naturally, so the tooth can still fall out on time.
That resorbable filling is the key difference from adult root canal treatment, where the filling material is permanent.
Either way, the tooth usually gets a stainless steel crown afterwards. A tooth with its pulp removed becomes brittle, and a filling alone tends to fracture.
Signs a child’s tooth may need it
- Pain that wakes them at night, which suggests the nerve is involved
- A toothache lasting more than a day or two
- Swelling of the gum or face
- A pimple-like bump on the gum near the tooth
- A tooth that’s turned grey or dark, especially after a knock
- Avoiding chewing on one side
- A large visible cavity or a broken-down tooth
- Sensitivity that lingers after something cold or sweet
Swelling with a fever needs same-day attention. Children can become unwell from dental infections faster than adults.
Pulp therapy or extraction?
| Situation | Usual recommendation |
|---|---|
| Tooth restorable, adult tooth years away | Pulp therapy and crown |
| Adult tooth due within months | Often extraction |
| Tooth broken below the gum | Extraction |
| Infection spread into surrounding bone | Usually extraction |
| Front baby tooth discoloured after a knock | Monitor, treat if symptomatic |
| Child cannot tolerate treatment | Discuss sedation options first |
Timing drives most of this. A 5-year-old with an infected molar needs that tooth for another 6 or 7 years. An 11-year-old with the same problem may be weeks from losing it naturally.
Where extraction is the right call, a space maintainer often follows to hold the gap open until the adult tooth arrives.
What the appointment is like
- Examination and X-ray to see how far the decay or infection extends and where the adult tooth sits.
- Explanation in child-friendly terms, because a child who knows what’s happening copes considerably better.
- Numbing the area with topical gel first, then local anaesthetic.
- Removing the decay and affected pulp.
- Placing a medicated dressing to settle the remaining tissue.
- Fitting a crown in the same visit in most cases.
- Aftercare instructions, usually soft food and over-the-counter pain relief for a day.
For anxious children, dentistry with nitrous oxide makes a real difference and wears off within minutes afterwards.
Two things parents often worry about
The silver crown. Stainless steel crowns look obvious, and they’re used because they last until the tooth falls out naturally. Tooth-coloured options exist for front teeth and some back teeth. It’s worth asking what suits your child’s case, since durability matters most on molars doing the chewing. Adult crowns and bridges are a different proposition entirely.
Whether it’s worth it on a tooth that falls out anyway. A baby molar that arrives at age 2 isn’t replaced until around 11. That’s 9 years of chewing, speech and holding space, and the treatment protects the adult tooth forming underneath.

Frequently asked questions
Does a baby root canal hurt?
The tooth is fully numbed, so the procedure itself shouldn’t hurt. Mild soreness for a day afterwards is normal and manageable with over-the-counter pain relief suited to your child’s age and weight.
How long does a treated baby tooth last?
The aim is until it falls out naturally, which the treatment usually achieves when a crown is fitted. The tooth sheds on its normal schedule because the filling material resorbs along with the root.
Will the adult tooth be affected?
Treating the infection promptly is what protects it. Long-standing infection above a developing tooth can disturb enamel formation, which is why leaving an infected baby tooth alone carries more risk than treating it.
My child’s front tooth went grey after a fall. Is that urgent?
Have it checked, though it isn’t always an emergency. Discolouration can be a bruised nerve that recovers, or a dying one that needs treatment. An X-ray and monitoring over a few months usually settles which it is.
Can pulp therapy be avoided?
Often, by catching decay early. Small cavities need only a filling, and sealants on new molars prevent many of them forming. Regular checkups from the first birthday are what keep treatment at the simple end.
Conclusion
Baby teeth do get root canal style treatment, called pulp therapy, and it’s usually preferred over extraction because those molars hold space until around age 12. Night pain, swelling or a greying tooth are the signals to get seen. Catching decay early avoids the whole question.
