Enamel is the hard substance that forms the protective covering of your teeth. Hypoplasia is a medical term used when a part of the body is underdeveloped. In the case of enamel hypoplasia, the formation of the enamel on a child's teeth is incomplete.
Hypoplastic teeth aren't always a problem. If caught early enough, they can be effectively managed and restored with careful dental care. If you're wondering if your child's teeth show signs of enamel hypoplasia, our dental professionals have put together this guide. Get in touch with us at JC Dental Como if your child needs dental care for enamel hypoplasia.
Enamel hypoplasia is a developmental condition that results in the incomplete or defective formation of the tooth enamel (the outermost protective layer of the teeth). It affects around 1 in 14,000 people.
This defect occurs during the stages of tooth development, either in utero or during early childhood. It can affect both primary teeth (baby teeth) and permanent teeth, and its severity can range from mild discolouration to significant enamel loss.
Hypoplasia in teeth is distinct from other enamel-related conditions, like hypomaturation (where enamel is softer) or hypomineralisation (where enamel is poorly mineralised).
Enamel hypoplasia can manifest in various ways, depending on how severe it is. It mainly affects the outer enamel layer of the teeth, leading to several distinct signs and symptoms.
Teeth affected by enamel hypoplasia may show visible defects, like pits, grooves, or irregular surfaces. These structural issues often result in uneven enamel thickness, making the surface of the teeth appear uneven or rough.
In severe cases, the enamel may be noticeably thinned, causing the underlying dentine to show through. This can lead to discolouration ranging from white to yellow or brown patches.
A tooth without enamel can be more sensitive to temperature changes, especially hot and cold food and drinks. This increased sensitivity happens because the thinner (or absent) enamel offers less protection to the tooth’s inner layers.
People suffering from enamel hypoplasia may also find it difficult to eat hard or chewy food, due to discomfort or increased sensitivity.
Teeth with enamel hypoplasia are more vulnerable to decay and dental caries. The weakened enamel makes it easier for bacteria to penetrate and cause cavities.
Pits and grooves in the enamel also provide hiding spots for bacteria, increasing the risk of plaque buildup and decay even more. People with this condition are more prone to tooth fractures due to the compromised strength of the affected teeth.
Enamel hypoplasia causes range from genetics, environmental causes, and prenatal and perinatal factors. In some cases, a combination of these things can lead to weak tooth enamel.

The diagnosis and treatment of enamel hypoplasia begins with a detailed assessment to gauge the severity of the damage. Treatment depends on how severe the case is, but may include careful maintenance, restorative options, or advanced options like remineralisation.
Diagnosing enamel hypoplasia starts with a thorough clinical evaluation by a dentist. This examination involves:
For a more detailed diagnosis, dentists may use several advanced tools:
Treatment for enamel hypoplasia depends on the severity of the condition, ranging from conservative management for mild cases to more extensive restorative procedures for severe cases. The goal is to protect the teeth, improve function, and address cosmetic concerns.
Mild Cases: Conservative Management
For mild cases of enamel hypoplasia, conservative treatments focus on strengthening the existing dental enamel and preventing further damage. These methods include:
Moderate to Severe Cases: Restorative Procedures
When enamel hypoplasia affects tooth structure or appearance more significantly, dentists may opt for restorative procedures. These treatments aim to protect the teeth and improve their appearance:
Advanced Therapeutic Options
For advanced cases of enamel hypoplasia, more specialised treatments can be used to protect and strengthen the teeth, addressing both functional and cosmetic concerns:
While it’s not possible to prevent hereditary enamel hypoplasia, there are steps that can be taken to reduce the risk of the condition caused by environmental factors. Mothers should take precautions while pregnant and parents of young children should also get their kids into good dental habits early on.
Proper prenatal care plays a big role in preventing enamel hypoplasia in babies. Mothers should aim to maintain a healthy pregnancy diet, rich in vitamins and minerals (particularly vitamins D and A), which support the development of strong teeth.
Prenatal vitamin supplements may be recommended by healthcare providers. Regular prenatal check-ups are also important to monitor overall maternal and foetal health. Avoiding smoking and substance use during pregnancy is a must, as these factors can interfere with enamel development in the foetus.
Parents should also get their kids into good habits from an early age, like brushing twice a day with fluoride toothpaste, flossing once or twice a week, and getting them used to visiting the dentist regularly. At JC Dental Como, our dentists love treating children and know how to put kids at ease. Visit us for a checkup!
Making sure kids eat a healthy diet can also reduce the chance of them developing severe enamel hypoplasia. Include foods that are high in calcium, vitamins, and minerals.
Yes, adults can develop enamel hypoplasia, although it’s much more common in childhood. Enamel hypoplasia occurs when the enamel does not form properly during tooth development, but adults can experience it if the condition wasn’t diagnosed or treated earlier.
Trauma or injury to the teeth, illness, or environmental factors during early childhood can sometimes lead to enamel hypoplasia in adult teeth later in life.
If enamel hypoplasia is left untreated, it can lead to several long-term complications. These include:
Enamel hypoplasia is relatively common, though its prevalence varies depending on the population and study. It’s estimated that between 6% to 10% of people worldwide have some form of enamel hypoplasia, and the condition can affect both baby and permanent teeth.
It’s often underdiagnosed, especially in its mild form, where only a few spots or discolourations are present. In more severe cases, the enamel defects are more pronounced, making diagnosis easier.
