What is Dentinogenesis Imperfecta and How Does It Harm Your Teeth?

Maintaining optimal oral health can be a challenge, especially for those with co-existing oral health problems. Dentinogenesis Imperfecta, a genetic disorder affecting approximately 1 in 7,000 people each year, presents numerous oral health complications. It’s important to become more aware of the impact of genetic conditions like Dentinogenesis Imperfecta on dental health. Let’s take a closer look at this condition, its symptoms, causes, and available treatment options. 

What is Dentinogenesis Imperfecta and How Does It Harm Your Teeth? 

Dentinogenesis Imperfecta is a genetic mutation that causes problems with the development and formation of dentin, the second layer of the tooth responsible for protecting and providing sensitivity to the tooth pulp. Abnormalities in the DSPP gene are the root cause of this genetic condition, as this gene plays a vital role in dentin formation. The mutation can be inherited from either parent or occur spontaneously without any previous family history of the disorder. 

Dentinogenesis imperfecta can be classified into three types: 

Type I: This type is observed in those who also have osteogenesis imperfecta, a genetic condition characterized by fragile, easily fractured bones, with a high correlation between the two conditions. 

Type II: Type II is considered the most common type, occurring without any underlying genetic conditions. It’s often seen in older populations experiencing age-related conditions such as hearing loss or deafness.

Type III: While not widely recognized as an official classification, certain studies have pointed out type II in isolated cases in those without hereditary conditions. 

The symptoms of dentinogenesis imperfecta revolve around the deterioration and weakness of the dentin. Tooth discoloration is one of the primary symptoms, causing the dentin to appear translucent, blue-gray color, or yellow-brown color. The teeth will also appear bulbous in shape and show signs of enamel wear, which increases the risk of breakage and decay. 

Although this condition doesn’t have a cure, your dentist can provide various treatments to help you prevent further damage to your teeth. Some of these treatment options include: 

  • Fluoride Treatment: Besides receiving regular cleanings from your dentist, fluoride treatments can help protect your remaining enamel and restrengthen it. 
  • Crowns and Veneers: When enamel and dentin breakage is present, your dentist can provide crowns, veneers, and dental bonding procedures to protect your teeth. 
  • Implants and Dentures: If your teeth show significant signs of wear and decay, then tooth extractions are needed, and the tooth can be replaced with implants, bridges, or dentures.
