A root canal in a child’s tooth is usually called a pulp therapy or pulpectomy/pulpotomy, depending on how much of the tooth nerve (“pulp”) is infected.
Why kids may need it
Common reasons include:
Deep cavities
Tooth infection or abscess
Tooth injury/trauma
Severe tooth pain or swelling
Saving a baby tooth is often important because it:
Helps chewing and speech
Keeps space for permanent teeth
Prevents neighboring teeth from shifting
Types of treatment
1. Pulpotomy (“baby tooth root canal”)
Used when infection is limited to the top part of the nerve.
The dentist:
Removes infected pulp from the crown part
Cleans the area
Places medicated material
Usually covers the tooth with a stainless-steel crown
This is the most common pediatric root canal procedure.
2. Pulpectomy
Used when infection reaches the roots.
The dentist:
Removes all infected pulp from roots and crown
Cleans and disinfects canals
Fills them with a material safe for baby teeth
Is it painful?
Modern pediatric dentistry uses local anesthesia, so the procedure is usually not painful. Kids may feel pressure but not sharp pain.
Signs your child might need one
Persistent toothache
Swelling of gums/face
Sensitivity to hot/cold
Pimple-like bump on gums
Darkened tooth
Pain while chewing
What happens after?
Mild soreness for 1–2 days is common
Soft foods may help initially
Good brushing and reduced sugary snacks are important
Baby teeth vs permanent teeth
Baby teeth: dentists often try to save them until they naturally fall out.
Permanent teeth in children: a full root canal may be needed if the nerve is damaged.
