What a Pulpectomy and a Root Canal Are
A pulpectomy and a root canal both remove damaged pulp from inside a tooth and clean out its root canals to stop infection.
Inside every tooth is a soft core called the pulp. It holds nerves and blood vessels. When deep tooth decay or a crack reaches this core, the infected tooth pulp can swell and cause pain. A pulpectomy or root canal removes that pulp and seals the space, which lets you keep the natural tooth [6].
The phrase pulpectomy vs root canal can be confusing because the two procedures overlap. A pulpectomy is the term dentists use for baby teeth, also called primary teeth. Root canal treatment usually describes the same dental procedure on permanent teeth. Both clean the root canals, but their goals differ. A pulpectomy keeps a baby tooth in place until it falls out on its own. Root canal treatment aims to keep a permanent tooth for many years [6].
Baby teeth matter more than many parents expect. They hold space for adult teeth and help a child chew and speak. Saving an infected baby tooth with a pulpectomy can help prevent crowding before the permanent teeth arrive [7].
When a Pulpectomy or Root Canal Is Recommended
Dentists recommend a pulpectomy or root canal when the pulp inside a tooth is badly infected or cannot heal on its own.
Deep tooth decay is the most common reason. Decay starts in the tooth enamel, the hard outer layer. If it is not treated, it moves deeper until it reaches the pulp and its blood vessels. A crack, repeated dental work, or an injury can also damage the pulp [6].
For baby teeth, a pediatric dentist may suggest a pulpectomy when the infected tooth pulp has spread through the whole pulp, including the roots. If only the top part of the pulp is affected, a smaller treatment called a pulpotomy may be enough. A baby root canal, or pulpectomy, is chosen when the damage is more extensive [6].
Sometimes a dentist performs a partial pulpectomy, removing only part of the pulp when the rest looks healthy. In permanent back teeth with decay-exposed pulp, research suggests a pulpotomy can work as an alternative to full root canal treatment in many cases [3]. When the pulp is exposed but still healthy, a pulp cap may protect it instead [5].
What to Expect Step by Step
Most root canals and pulpectomies follow the same path: numb the tooth, remove the pulp, clean the root canals, then seal them.
Before the Procedure
Your dentist starts with an exam and X-rays. The images show the shape of the root canals and how far the infection has spread. The tooth and the gum around it are numbed with local anesthetic, so the area feels no pain during the work. A thin sheet called a rubber dam keeps the tooth dry and clean [6].
During the Procedure
The dentist makes a small opening in the top of the tooth to reach the pulp chamber. Using fine files, they remove the infected tooth pulp from the pulp chamber and the root canals. For baby teeth, studies compare hand files with rotary files, and both can clean the canals well [2][1]. Imaging research shows the file system must follow the thin, curved canals of baby teeth carefully to avoid harm [4]. The dentist then washes the entire root canal system with a disinfecting rinse.
Sealing and Restoring the Tooth
Once the root canals are clean and dry, the dentist fills them. A baby tooth often gets a paste the body can absorb as the roots dissolve and the permanent tooth begins to come in. A permanent tooth gets a longer-lasting material that stays in place. Most teeth then need a crown or filling to rebuild the lost tooth enamel and protect the structure. The whole root canal procedure often takes one or two visits [6].
Recovery and Aftercare
Most people feel back to normal within a few days after root canals, though mild soreness around the tooth is common at first.
On day one, the numbness wears off in a few hours. The tooth and gum may feel tender, and over-the-counter pain relievers usually help. Eat soft foods and chew on the other side until the soreness fades.
Within the first week, most tenderness goes away. By the first month, the tooth should feel like your other teeth. If your dentist placed a temporary filling, you return to have a permanent crown or filling added [6].
Some discomfort is normal. Call the office if you have severe pain, swelling, a fever, or a bite that feels uneven after a few days. To shield a treated tooth and the rest of the teeth from injury, ask about a mouth guard if your child plays sports or grinds their teeth at night [7].
Cost, Insurance, and Financing
The pulpectomy vs root canal cost gap is real: treating a baby tooth usually costs less than root canal treatment on a permanent tooth.
In the United States, a pulpectomy on a baby tooth often runs from roughly $150 to $500. Root canal treatment on a permanent tooth tends to cost more, commonly from about $700 to $1,800, with molars at the higher end because they have more root canals. Costs vary by location, provider, and case complexity. These figures usually do not include a crown, which adds to the total.
Dental insurance often covers part of the cost, especially on baby teeth and on permanent teeth that can be saved. Coverage levels differ by plan, so check your benefits before treatment.
If you do not have insurance, many offices offer payment plans or work with outside financing companies. Ask the front desk what options exist before the root canal procedure begins.
Specialist vs. General Dentist
A general or pediatric dentist handles many pulpectomies and root canals, but complex cases often go to an endodontist.
An endodontist is a dentist with extra training in treating the inside of teeth, including the pulp and root canals. They use a microscope and detailed imaging to find and clean every canal, even in teeth with curved or extra roots [6].
For baby teeth, a pediatric dentist is often the right choice. They focus on treating children and on procedures like a baby root canal. They also know how to keep a child calm during a dental procedure on a child's baby tooth [7].
Your dentist may refer you to a specialist when a tooth has many root canals, when a past root canal needs redoing, or when the anatomy is unusual. You can learn more on the endodontics page. Working with the right provider improves the odds the entire root canal system is fully cleaned.
