Pediatric Pulpotomy in Renton, WA
A pulpotomy is a common pediatric dental procedure that saves a baby tooth when decay has reached the nerve (pulp) inside the tooth. Sometimes called a "baby root canal," a pulpotomy at The Kids' Dentist and Orthodontics in Renton, WA removes only the infected portion of the nerve while preserving the healthy root and tooth structure. This allows your child to keep their tooth until it naturally falls out on its own schedule.
When Is a Pulpotomy Needed?
A pulpotomy is recommended when tooth decay extends deep enough to reach or inflame the pulp (the nerve and blood supply inside the tooth), but the infection has not yet spread to the tooth roots. Signs that your child may need a pulpotomy include:
- Persistent toothache, especially at night
- Sensitivity to hot or cold that lingers
- A deep cavity visible on X-ray that is close to or touching the nerve
- Swelling around the affected tooth
- Pain when chewing or biting
The Pulpotomy Procedure
Our pediatric dentists perform pulpotomies with gentle technique and appropriate sedation for your child's comfort. The procedure involves:
- Numbing the area with local anesthesia (sedation options available)
- Removing the decayed portion of the tooth
- Removing the infected pulp tissue from the crown of the tooth
- Placing medicated material over the remaining healthy pulp
- Restoring the tooth with a pediatric crown for protection
The entire procedure typically takes 30 to 45 minutes. Most children experience minimal discomfort afterward and return to normal activities the same day.
Why Save a Baby Tooth?
Baby teeth serve important functions beyond chewing. They maintain proper spacing for developing permanent teeth, support speech development, and contribute to your child's self-confidence. Losing a baby tooth too early can cause neighboring teeth to shift, potentially creating alignment problems that require orthodontic treatment later.
After the Pulpotomy
Your child may experience mild sensitivity for a day or two after the procedure. Over-the-counter children's pain relief is usually sufficient. The tooth is typically restored with a stainless steel or white crown on the same day as the pulpotomy, providing immediate protection and allowing your child to use the tooth normally.
Pulpotomy FAQs
A pulpotomy removes only the infected pulp from the crown (top portion) of the tooth. A full root canal (pulpectomy) removes all pulp tissue from both the crown and roots. Pulpotomies are the more common procedure in baby teeth because they are less invasive and the root structure is preserved.
