Baby Teeth Have a Soft Core

Milk teeth are much smaller than permanent teeth, and the pulp (nerves and blood vessels) inside them is closer to the surface. When a cavity goes deep, it usually reaches this pulp. A simple filling can cover the hole, but it cannot remove the infected pulp tissue underneath. That infection can spread, causing pain, swelling, or even damage to the developing permanent tooth. Moreover, a hard filling directly impinging on the pulp also causes unnecessary pressure during chewing, which leads to severe pain.

Pulpectomy Protects the Tooth and the Child

A pulpectomy is like a “root canal for kids.” The infected pulp is gently cleaned out and replaced with a safe material. This keeps the tooth infection-free while still holding its place in the jaw until the permanent tooth is ready to come in.

Why a Crown Is Needed After

After pulpectomy, the tooth becomes weaker and more likely to break. A crown (a protective cap) acts like a helmet for the tooth—restoring its shape, strength, and function. This allows the child to chew comfortably and prevents the tooth from breaking down further. Yes, the crown will fall along with the tooth during its shedding time; there is no need for crown removal.

What If We Just Fill It?

If only a filling is done when the pulp is already affected:

• The infection continues inside.
• Pain or swelling can return.
• The tooth may have to be extracted earlier than expected.
• Losing a baby tooth too soon can cause spacing problems and crooked permanent teeth later.
