Preserving Your Child's Natural Tooth
At Molina Endodontics, Dr. Sonia Molina brings over three decades of dedicated endodontic experience to every case — including complex treatments for immature teeth. Our practice accepts an extensive range of PPO and insurance plans, and our team provides care in both English and Spanish so every family feels informed and comfortable throughout the process.
If your child has been referred for this procedure, we're here to help preserve their natural tooth and support healthy development during these critical growth years.
Why Apexification Matters for Developing Teeth
In children and adolescents, permanent teeth may take several years after eruption for the root to fully form and close at the tip (apex). When trauma — such as a fall or sports injury — or deep decay damages the tooth's inner pulp before that root development is complete, standard endodontic treatments may not be sufficient. The open, undeveloped root tip presents a unique clinical challenge because there is no natural barrier to seal against.
Apexification addresses this challenge by encouraging or placing a hard-tissue barrier at the open root end. This barrier is designed to allow the tooth to be properly sealed and restored, preserving the natural tooth structure and supporting continued jaw development during critical growth years.
Who Needs the Apexification Procedure
The apexification procedure is most commonly recommended for children and teenagers whose permanent teeth have experienced:
Dental Trauma
A blow to the mouth that damages or kills the tooth's pulp.
Deep Infection
Bacteria reaching the pulp chamber before root maturation.
Failed Prior Treatment
Cases where earlier intervention did not resolve the issue.
If your dentist has identified an immature tooth with pulp damage and referred your child to an endodontist, this is likely the treatment they are recommending.
Immature Tooth Root Canal vs. Standard Root Canal
A standard root canal therapy procedure is designed for fully developed teeth with closed root tips. The endodontist removes infected pulp tissue, shapes the canal, and seals it with a filling material. This approach relies on the root having a defined, narrow endpoint.
An immature tooth root canal requires a different strategy. Because the root apex is wide open and the canal walls may be thin, the tooth cannot be sealed in the conventional way. The apexification procedure creates the necessary barrier first, so the tooth can then be treated and restored in a manner that helps it remain functional for years to come.
What to Expect During Apexification
Treatment begins with a thorough evaluation, including advanced 3D imaging to assess the stage of root development and the extent of damage. Dr. Molina will explain the findings and recommended approach in clear terms so you and your child know exactly what to expect.
During the procedure, the damaged pulp tissue is carefully removed and the canal is cleaned and disinfected. From there, the specific technique depends on your child's case.
MTA Apexification vs. Calcium Hydroxide Approach
MTA (Mineral Trioxide Aggregate)
A biocompatible material is placed directly at the open root tip to form an immediate artificial barrier. This approach is often completed in one or two visits and is designed to allow faster final restoration of the tooth.
Calcium Hydroxide Approach
A medicated paste is placed inside the canal and replaced periodically over several months to encourage the body to form its own hard-tissue barrier naturally. This method requires multiple appointments and a longer treatment timeline.
Dr. Molina will recommend the approach best suited to the tooth's condition and your child's needs. Sedation and comfort options — including nitrous oxide and oral sedation — are available to help younger or anxious patients feel at ease during every visit.
Benefits of Choosing a Specialist for Apexification
Treating immature teeth requires specialized training and clinical judgment. As a dedicated endodontist with a Harvard DMD and UCLA endodontic residency, Dr. Molina has the advanced expertise needed for these complex cases.
Precision Diagnosis
3D CT imaging is used to evaluate root development accurately before any treatment begins.
Delicate Root Structures
Experience with thin, developing canal walls that require careful, measured treatment.
Advanced Materials
Access to materials such as MTA for predictable, reliable barrier formation.
Referring Dentist Coordination
Seamless coordination with your dentist for follow-up care and final restoration.
If your child needs urgent evaluation for a traumatized tooth, our office accommodates same-day emergency appointments whenever possible.
Frequently Asked Questions About Apexification
Apexification is an endodontic procedure designed to create a hard-tissue barrier at the open tip of an immature tooth root. It is typically needed when a young patient's developing tooth has been damaged by trauma or deep infection before the root has fully formed.
The initial appointment typically takes about one hour. Depending on the approach used, the full treatment timeline may range from a single visit with MTA placement to multiple visits over several months with calcium hydroxide therapy. Your endodontist will outline the expected timeline based on your child's specific case.
The procedure is performed under local anesthesia, so patients typically feel little to no discomfort during treatment. Sedation options including nitrous oxide and oral sedation are available for younger or anxious patients. Mild soreness after the appointment is normal and usually resolves within a few days.
Without treatment, an infected or damaged immature tooth may develop a worsening infection that spreads to surrounding bone and tissue. The tooth may eventually need to be extracted, which can affect jaw development in younger patients and require more complex restorative work later.
