Understanding Dentinogenesis Imperfecta Type 2 (DGI-II)

At a Glance

Dentinogenesis Imperfecta Type 2 (DGI-II) is a rare genetic condition that weakens tooth dentin, causing discoloration, flaking enamel, and rapid wear. Early diagnosis and proactive dental treatments, such as protective crowns, are essential to preserve teeth and maintain long-term oral health.

Welcome to your guide on Dentinogenesis Imperfecta Type 2 (DGI-II). Hearing that you or your child has a rare genetic dental condition can be overwhelming, but you are not alone. DGI-II is a condition that affects how the foundation of your teeth—the dentin—is built. While it presents lifelong challenges for your smile, modern dentistry offers clear, effective ways to protect and preserve your teeth.

This guide is designed to help you understand what DGI-II is, how it behaves, and what you can do about it. It will prepare you to have informed, confident conversations with your dental care team.

Common questions in this guide

How does Dentinogenesis Imperfecta Type 2 affect the teeth?
DGI-II alters how dentin, the foundational layer of the tooth, is built. This typically causes teeth to appear discolored, leads to enamel flaking off, and increases the risk of rapid tooth wear over time.
What are the standard treatments for DGI-II?
Treatment focuses on protecting the teeth and maintaining the bite structure. Standard care often involves placing dental crowns on both baby and adult teeth to prevent wear, and in the long term, may include dental implants.
Should my family get genetic testing for DGI-II?
Yes, genetic testing can confirm a DGI-II diagnosis and help rule out related conditions with similar dental symptoms, such as Osteogenesis Imperfecta. A genetic counselor can help discuss testing options for your family.
How often should someone with DGI-II see a dentist?
Patients with DGI-II require frequent monitoring to check for tooth wear, hidden infections, and developmental changes. Your dental team will recommend a personalized schedule for routine checkups and necessary interventions.
