Baby Tooth Root Canals: Pulpal Therapy on Primary Teeth

What pulpal therapy, primary tooth involves

This is root canal treatment for a baby tooth, sometimes called a pulpectomy. The whole pulp is removed — crown and roots — the canals are cleaned, and they are filled with a resorbable paste rather than the permanent material used in adult teeth. The resorbable filling is the essential difference. A baby tooth's roots dissolve naturally as the permanent tooth pushes up beneath it, and the filling material has to dissolve with them. Filling a primary root with gutta-percha would leave an unresorbable obstruction in the path of the permanent tooth.

When this treatment is used

Used on a primary tooth whose pulp is irreversibly inflamed or dead throughout — beyond what a pulpotomy can manage — but where the tooth is still worth keeping because the permanent successor is years away and losing the tooth would collapse the space.

Keep it or take it out?

This is the real decision, and it turns on timing. A six-year-old with an abscessed second primary molar has six years to wait for the successor — that space is worth keeping, and pulpal therapy avoids a space maintainer plus the risk of crowding. A ten-year-old with the same tooth and a successor almost through is usually better served by extraction. Other factors: the extent of root resorption already present, whether the infection has damaged the developing permanent tooth, whether the child can cooperate for a longer procedure, and whether the crown of the baby tooth is restorable at all.

Costs and insurance in summary

Typical fee range across the group: $0–$0 where a single band applies. Several codes here are priced individually and carry their own range on their own page. Priced below adult root canal treatment. The crown that follows is a separate charge.

Benefit category: Basic, typically 70–80% on a typical plan. Generally covered for children. Plans may compare the cost against extraction and a space maintainer, particularly on a tooth close to natural exfoliation.

Common restrictions: May be denied on a tooth near natural exfoliation; A subsequent crown is expected; Once per tooth.
