Pulpotomy vs root canal: what a partial root canal is and when it saves the tooth

A pulpotomy is a partial root canal: the dentist removes only the inflamed pulp in the crown of the tooth and leaves the healthy pulp in the roots to keep working. It is the standard way to save a baby tooth with a deep cavity, and dentists also use it in selected adult teeth before a full root canal. You are numbed first, most people are back to normal within a few days, and the tooth is sealed afterward, usually with a crown. This guide explains how pulpotomy, pulpectomy, and root canal differ and what the visit looks like.

What is a pulpotomy?

A pulpotomy is a dental procedure that removes the damaged part of the pulp and keeps the rest. The pulp is the soft tissue inside the tooth that holds its nerves and blood vessels. Part of it sits in the crown, the visible part of the tooth. Part of it runs down through the roots.

In a pulpotomy, the dentist takes out the pulp in the crown only. The pulp in the roots stays. The dentist then places a medicated filling over the openings of the root canals, which protects the roots and lowers the chance of a new infection, and seals the tooth. Cleveland Clinic describes it as a treatment that "leaves your tooth root in place" and says it is most often done to treat decay in baby teeth.

You may hear it called a baby root canal. As shorthand that is fair, but the procedure is smaller than a root canal. Our pulpotomy service page covers what we offer in the office.

Why the pulp matters

Pulp keeps a tooth alive. It brings blood to the tooth and carries the nerve that warns you when something is wrong. When a cavity grows deep, bacteria reach the pulp and it becomes inflamed. That is when a tooth aches at night or hurts with hot and cold that lingers.

Inflammation is not always the end of the pulp. In some teeth the damage stays in the crown while the pulp in the roots is still healthy. A pulpotomy removes what is damaged and protects the rest. Unsure whether an ache is a cavity? Our guide on how to tell if you have a cavity lists the warning signs.

Why pulpotomies are common in baby teeth

Most pulpotomies are done on children. Cleveland Clinic notes that most have a cavity in a back baby tooth, a molar. Baby molars have thin enamel, and a cavity can reach the pulp quickly.

Pulling the tooth is not a harmless shortcut. A baby molar holds the space where the adult tooth will erupt, and if it comes out years early, neighboring teeth can drift into the gap. A pulpotomy keeps the baby tooth in place until it falls out on its own. Cleveland Clinic says most children lose their back baby teeth between ages 9 and 12, though every child is different.

Pulpotomy vs pulpectomy vs root canal

These three treatments sit on a ladder. The deeper the damage goes, the more pulp has to be removed.

1. Pulpotomy: removes the pulp in the crown only. The pulp in the roots stays and keeps the tooth alive. Used in baby teeth, and in selected adult teeth.
2. Pulpectomy: removes all of the pulp, crown and roots, from a baby tooth. The canals are cleaned and filled with a material that the body can absorb as the baby tooth's roots dissolve naturally.
3. Root canal: removes all of the pulp from a permanent tooth, cleans and shapes the canals, and fills them to seal out bacteria. The tooth then needs a filling or crown.

The practical difference is how much of the tooth's inner tissue you keep. The American Dental Association describes a root canal as removing the nerve from inside the tooth and in the roots, then cleaning, filling, and sealing the canals. A pulpotomy stops well short of that.

How far the infection has traveled decides the rung. If the pulp in the roots is also infected, a pulpotomy will not be enough. Cleveland Clinic says plainly that if a pulpotomy does not remove all the unhealthy pulp, the child may need another pulpotomy, a pulpectomy, or an extraction. We cover the full procedure in our post on root canals in Minneola, and our endodontics services page lists the rest.

Can adults have a pulpotomy?

Yes, in the right case. For years, a permanent tooth with an inflamed pulp and a lingering toothache was assumed to need a root canal. That thinking has shifted. Studies now look at pulpotomy as a more conservative option for adult teeth with deep decay, and Cleveland Clinic notes it may be an alternative to a root canal.

Here is what the research says. A 2022 meta-analysis in Scientific Reports pooled 11 studies of pulpotomy in permanent teeth with irreversible pulpitis from a carious exposure. The pooled success rate was 86%. Teeth with symptoms did about as well as teeth without. Teeth with an open apex, meaning the root had not finished forming, did better than closed apex teeth, 96% against 83%. The authors noted that results differed from study to study, and these figures come from selected cases, so they do not predict how your own tooth will do.

How likely is a pulpotomy to work?

In baby teeth, the evidence is strong. An overview of systematic reviews in the International Journal of Paediatric Dentistry (2022) found success rates above 80% across time periods for every pulpotomy medicament and technique it examined except calcium hydroxide. Most comparisons showed no clear difference between materials, and much of the underlying evidence is weak.

Success is not only about the material. A 2021 review in the journal Children states that a pulpotomy is highly technique sensitive and depends on diagnosis accuracy, how the decay is removed, the dressing material, the quality of the final restoration, and operator experience.

Who is a good candidate for a pulpotomy?

A good candidate is a tooth where the damage is confined to the crown and the pulp in the roots is still healthy. A dentist weighs a few things:

• Symptoms: short, sharp pain or lingering cold sensitivity can fit a pulp that is inflamed but able to recover. Constant throbbing, swelling, or a pimple on the gum suggests a deeper infection.
• X-rays: they show how deep the cavity is, how much tooth is left, and whether there is infection around the root tip.
• What the dentist finds inside: healthy pulp bleeds in a controlled way and stops. Pulp that keeps bleeding heavily, or looks dead, points toward a pulpectomy or a root canal.
• Whether the tooth can be restored: a tooth with too little structure left to hold a crown may not be worth saving.

This is why we cannot say over the phone which treatment you need.

The visit, step by step

Here is what a pulpotomy appointment looks like. Cleveland Clinic describes the same steps and puts the procedure at about 30 to 45 minutes.

1. Numbing: you get a local anesthetic near the tooth. Anxious children may be offered mild sedation first.
2. Isolation: a thin rubber sheet called a dental dam goes over the tooth to keep it dry and clean.
3. Access: the dentist makes a small opening in the top of the tooth to reach the pulp chamber.
4. Removal: the inflamed pulp in the crown is taken out.
5. Protection: the dentist places a medicated material over the remaining pulp to protect the roots and reduce the chance of a new infection.
6. Seal: the top of the tooth is sealed with dental cement or filling material.
7. Crown: the tooth is usually restored with a crown, at the same visit or a few weeks later, once the infection has clearly settled.

Aftercare: the first few days

Recovery from a pulpotomy is usually quick. Numbness lasts a few hours, so avoid chewing until it fades. It is easy to bite your cheek without feeling it. If your child had sedation, Cleveland Clinic says it can take up to 24 hours to wear off.

Mild soreness around the tooth is normal for a few days, and over-the-counter pain relievers at the dose your dentist recommends usually cover it. Stick to soft foods the first day. If the tooth has a temporary filling, avoid sticky candy and hard foods until the crown is on.

Call the office if you notice any of the following, which Cleveland Clinic lists as reasons to contact your dentist:

• Severe pain that does not go away with medication
• A swollen face or jaw
• Fever, chills, or other signs of infection

Swelling and fever mean infection may be spreading, so do not wait for the next business day.

Why the crown afterward matters

A tooth that needed a pulpotomy had a deep cavity, so much of the crown was already gone. What remains is weaker, and chewing forces can crack it. In baby molars a crown seals the tooth and holds up until it falls out. In adults a permanent crown protects it long term. Our page on dental crowns explains the materials we use. Skipping the crown is a common reason a good pulpotomy fails later, because bacteria find a way in around a worn filling.

How to avoid needing a pulpotomy

Almost every pulpotomy starts with a cavity that went unnoticed or untreated, so prevention is simple, though not always easy.

• Brush twice a day with fluoride toothpaste and clean between teeth daily.
• Do not let a child fall asleep with a bottle of milk or juice.
• Schedule exams about every six months, so small cavities get a small filling.
• Treat tooth pain as a signal even when it comes and goes. A tooth that hurt for two days and then stopped may have lost its nerve, not healed.

Frequently asked questions about pulpotomy

What is a pulpotomy?

A pulpotomy is a dental procedure that removes the inflamed or infected pulp from the crown of a tooth and leaves the pulp in the roots in place. The dentist covers the area with a medicated material and seals the tooth, usually with a crown. It is the most common way to treat a deep cavity in a baby tooth.

Is a pulpotomy the same as a root canal?

No. A pulpotomy removes only the pulp in the crown and keeps the roots untouched. A root canal removes all of the pulp, including the pulp inside the root canals, then cleans and fills them. A pulpotomy is the smaller treatment, and it only works when the pulp in the roots is still healthy enough to heal.

Can adults get a pulpotomy?

Sometimes, yes. Research on permanent teeth with deep decay has found that removing only the top of the pulp can work in selected cases, and some dentists offer it as an alternative to a root canal. Whether it fits you depends on your symptoms, an X-ray, and what the dentist sees once the cavity is cleaned out.

Does a pulpotomy hurt, and how long does recovery take?

You are numbed first, so the procedure itself should not hurt. It takes about 30 to 45 minutes. Mild soreness for a few days is normal and usually settles on its own. Numbness fades in a few hours. Call your dentist for severe pain, a swollen face or jaw, or fever.

How long does a pulpotomy last?

In a baby tooth, the treatment is expected to last until the permanent tooth replaces it, which for back teeth is usually between ages 9 and 12. In an adult tooth, how long it lasts depends on the case and on the final crown or filling. Sometimes the tooth needs further treatment, such as a root canal.
