Your teeth have a strange colour — maybe blue-grey or amber. They seem to wear down faster than other people's teeth do. Your dentist mentioned dentinogenesis imperfecta. Here is what that means.
What Dentinogenesis Imperfecta Actually Is
Dentinogenesis imperfecta is a hereditary condition that affects the dentine — the layer of tooth found beneath the enamel. The dentine does not form properly, which makes teeth weaker, discoloured, and more prone to wear and damage.
It affects both baby teeth and permanent teeth. The condition is genetic, meaning it is passed down from parent to child through families.
What It Looks Like
The most obvious sign is tooth colour. Teeth with dentinogenesis imperfecta often appear blue-grey, amber, or brownish. They may have an opalescent sheen — almost like a soap bubble catching the light.
The colour happens because the abnormal dentine shows through the enamel. Unlike surface stains, the discolouration is built into the tooth itself.
How It Affects Your Teeth
Because the dentine is abnormal, the enamel on top tends to chip and wear away more easily. Teeth can become shorter over time as they grind down. Your bite may collapse, meaning your jaws do not meet properly when you close your mouth.
You might also experience sensitivity, especially to temperature changes. The teeth are structurally weaker than normal teeth, so they are more vulnerable to cracks and fractures.
How It Is Treated
Dentinogenesis imperfecta cannot be reversed, but it can be managed effectively. Treatment depends on how severely your teeth are affected. Options include:
• Crowns to protect weak teeth and restore their shape
• Composite bonding for minor damage
• Orthodontics if your bite has collapsed
• In severe cases, extractions and dentures or implants
Your dentist will create a treatment plan based on your specific situation. The goal is to protect your teeth, restore function, and maintain your smile.
What You Should Do
If dentinogenesis imperfecta runs in your family, let your dentist know. Regular check-ups are important to monitor your teeth and catch any problems early. Do not wait for pain or visible damage — proactive care makes a big difference.
