Your teeth appear opalescent or discoloured, and they're wearing down faster than normal. Dentinogenesis imperfecta is a genetic condition affecting the dentine layer of all your teeth. Here's what it means.

Dentinogenesis imperfecta affects the dentine — the layer of tooth structure that lies beneath the enamel. It is caused by mutations in the DSPP gene and is inherited in an autosomal dominant pattern, meaning you only need one affected copy of the gene from one parent to develop the condition. It can affect both your baby teeth and your permanent teeth.

What does it look like?

Teeth with dentinogenesis imperfecta have a distinctive opalescent sheen — they may appear blue-gray, brown, or amber-coloured, often somewhat translucent. The enamel chips away more easily because the underlying dentine is softer and does not support it properly. This leads to rapid wear, a flattened bite appearance, and teeth that look smaller over time.

What problems does it cause?

The main concerns are accelerated tooth wear and an increased risk of fractures and cavities. The softer dentine breaks down faster, which can cause the enamel to crack or flake off. This leads to sensitivity, difficulty chewing, and potential jaw problems from uneven bite pressure. The baby teeth are often affected more severely, but permanent teeth show the same pattern.

How is it managed?

Treatment aims to protect your teeth from further damage. Full-coverage crowns are often the go-to solution — they shield the entire tooth and distribute bite forces evenly. Restorations rebuild worn surfaces and restore function. In some cases, root canal treatment is needed if the pulp becomes infected. Orthodontics may be necessary if the bite collapses significantly. Early intervention and regular monitoring are essential to prevent complications.

What to do if you suspect this condition

If you or your child show signs of dentinogenesis imperfecta, see your dentist promptly for a proper diagnosis and personalised treatment plan. Modern dentistry offers effective ways to protect your teeth and maintain a healthy smile.
