Pulpotomy (Baby Root Canal) 

What Is a Pulpotomy?

A pulpotomy is a type of pulp therapy used on primary teeth (baby teeth). Instead of removing the entire pulp, only the diseased pulp tissue in the tooth chamber (crown portion) is taken out, while the healthy pulp in the roots is left intact.

The empty space is filled with a biocompatible material. Finally, the tooth is protected with a crown to restore strength and prevent bacteria from re-entering.

Think of a pulpotomy as a way to “rescue” the tooth’s nerve tissue while keeping the root alive.

Why We May Recommend a Pulpotomy

We may suggest a pulpotomy if your child has:

• Deep cavities that extend close to the pulp.
• Short-term pain or sensitivity, sometimes with a foul smell from the tooth.
• Traumatic injury, like a fall or sports accident, that exposes the pulp.
• Inflammation in the pulp chamber that makes a filling or crown alone insufficient.

Routine dental exams and digital dental X-rays help to catch these issues early and make treatment simpler and less invasive. Preventive care, such as sealants, fluoride treatments, and maintaining strong daily brushing and eating habits, also helps lower the risk of problems that could require pulp therapy.

Why Saving the Tooth Matters

Parents sometimes wonder if it’s easier just to pull a baby tooth. But saving the natural tooth with a pulpotomy has important benefits:

• Maintains space for permanent teeth and prevents shifting, crowding, or a misaligned bite.
• Supports proper chewing and dental arch development.
• Protects the structure of the tooth until it naturally falls out.

Keeping a primary tooth is always our first priority. If the tooth can be saved with a pulpotomy, that is what we will recommend. 

What to Expect During a Pulpotomy

Every step is designed to keep your child comfortable:

1. Comfort first: The tooth is numbed with an intraosseous injection, a quick and highly directed numbing technique. Laughing gas (nitrous oxide) can be used to help your child relax. For children who are very anxious or require extensive treatment, sedation or general anesthesia may also be discussed.
2. Isolate the tooth: An Isolite system is placed. The soft mouthpiece keeps the tooth dry and slips in and out easily, which helps your child stay comfortable during treatment.
3. Remove decay: Diseased pulp tissue is carefully removed from the crown chamber.
4. Seal and restore: The chamber is filled with a biocompatible material and covered with a durable dental crown for strength.

Our goal is always the same: protect the tooth, protect your child’s comfort, and build confidence in the dental chair.

Vital Pulp Therapy

Vital pulp therapy (VPT) is another option for young permanent teeth with deep decay. Instead of removing all pulp tissue, VPT focuses on preserving healthy nerve tissue so the tooth remains vital, or alive. 

Vital pulp therapy is often recommended for:

• Young permanent teeth with deep decay extending into the pulp.
• Cases where maintaining the vitality of the tooth nerves is especially important for continued growth and development of the tooth.

This treatment may involve a partial pulpotomy or other techniques that allow the tooth to heal naturally.

Vital Pulp Therapy Procedure

Here’s what typically happens during the procedure:

• The tooth is numbed to prevent pain. Laughing gas (nitrous oxide) can be used to help your child relax. For more involved treatments, sedation or general anesthesia may be recommended to help your child stay relaxed or comfortably asleep throughout the procedure.
• Only the portion of pulp that is damaged or inflamed is removed.
• A biocompatible material is placed over the healthy tissue to protect and encourage healing.
• The tooth is sealed with a filling or crown to keep bacteria out.
  

This approach preserves living tissue so that the tooth can continue to grow and develop naturally.

Caring for Teeth After Treatment

With the right care, a treated tooth can remain healthy until it falls out naturally. We’ll provide aftercare instructions, which usually include:

• Good oral hygiene: Brushing and flossing daily to protect the restored tooth.
• Healthy foods: Nutritious snacks that support strong teeth and reduce the risk of new cavities.
• Routine dental visits: Regular cleanings and exams to monitor healing and overall dental development.
• Avoid sticky foods: Protect the crown by steering clear of sticky or chewy snacks.

Pulpotomy vs. Pulpectomy vs. Vital Pulp Therapy

These treatments all fall under the category of pulp therapy, but they are recommended for different teeth and situations.

Pulpotomy	Pulpectomy	Vital Pulp Therapy (VPT)
Typically recommended for primary teeth when decay has reached the pulp chamber, but the root tissue is still healthy.	Typically performed on permanent teeth, rarely performed on baby teeth.	Typically recommended for young permanent teeth.
Removes diseased pulp tissue only from the crown chamber.	Removes all pulp tissue from both the crown and the root canals.	Removes only the inflamed or damaged portion of pulp, leaving healthy pulp intact.
Root pulp remains alive and functional. This aids in the tooth falling out naturally.	Root pulp is completely removed.	Root pulp remains alive and functional so the tooth can continue to grow and develop.
Sealed with a biocompatible or resorbable material in the crown chamber.	Empty space is filled with a biocompatible material.	Covered with a biocompatible material to encourage healing.
Restored with a dental crown for protection and higher success rate.	Restored with a crown or filling.	Restored with a crown or filling.
