Enamel hypoplasia is a deficiency of tooth enamel and a disorder of its quality. Tooth enamel protects teeth from destruction or wear. Its deficiency can make teeth more susceptible to cavities, erosion, and other problems. Treatment includes procedures that protect the teeth and improve their appearance.
What is enamel hypoplasia?
Tooth enamel is the hard layer that covers the teeth and protects their sensitive internal parts, including dentin and pulp. Tooth enamel is the hardest substance in the entire body. Enamel consists of 96% minerals, which makes it stronger than bone and resistant to damage.
Enamel hypoplasia occurs when tooth enamel does not form properly, resulting in enamel that is too thin. Unlike tooth erosion, where enamel gradually wears away over time, enamel hypoplasia is simply a deficiency or deterioration in enamel quality.
Diseases or environmental factors interfere with the proper formation of enamel even before the teeth erupt in the mouth. Depending on the cause, enamel hypoplasia may affect both primary and permanent teeth. Enamel may be thin or absent on only one tooth, or a person may have several hypoplastic teeth.
Problems with enamel development are quite common. One of the most common causes of enamel hypoplasia is a condition called amelogenesis imperfecta, which affects approximately 1 in 700 people in less developed countries. In the United States, for example, it is less common and occurs in about 1 in 14,000 people.
Symptoms
Signs and symptoms of enamel hypoplasia include:
- teeth with pits, grooves, or cracks;
- worn or chipped teeth;
- yellowish or brown spots on the teeth;
- white spots on the teeth;
- sensitivity to hot and cold foods or drinks.
Causes
If you or your child has enamel hypoplasia, it means that something disrupted enamel development at a critical moment. Tooth enamel begins forming during fetal development and continues throughout childhood.
Enamel on different teeth forms at different times. On some teeth, enamel may be insufficient or completely absent, while on others it may develop normally.
Genetic factors
Several rare conditions can cause enamel hypoplasia. These involve inheriting a gene from one or both biological parents that results in enamel being too thin or completely absent.
Syndromes that can cause enamel hypoplasia include:
- amelogenesis imperfecta;
- DiGeorge syndrome;
- Ellis-van Creveld syndrome;
- Heimler syndrome;
- otodental syndrome;
- Seckel syndrome;
- Treacher Collins syndrome;
- Usher syndrome.
Environmental factors
Various factors can affect enamel development both during pregnancy and after birth. Pregnancy-related complications may influence the development of a child’s primary teeth even before birth.
A child may develop enamel hypoplasia if the mother:
- has gestational diabetes;
- has vitamin D deficiency;
- does not receive prenatal care;
- has a habit of smoking.
Other factors that may interfere with enamel development include:
- dental trauma;
- deficiency of vitamins A, C, D, or calcium;
- dental fluorosis, a condition that occurs in young children aged eight years or younger who consume excessive amounts of fluoride.
Viral and bacterial infections
Certain diseases, including liver disease, cerebral palsy, and celiac disease, can lead to enamel hypoplasia.
Possible complications
Hypoplastic teeth do not have the same level of protection as teeth fully covered with enamel.
This can cause teeth to soften and wear down, leading to several problems:
- cavities;
- tooth erosion;
- malocclusion (improper bite);
- teeth may become brown in color;
- severe tooth sensitivity or pain during brushing.
Diagnosis
A dentist checks for signs of enamel hypoplasia, such as pits or white spots on the teeth, during a dental examination. It is important to schedule a child’s first dental visit within six months after the first tooth appears or by their first birthday.
During the first visit, the dentist will check for developmental dental problems such as enamel hypoplasia. Early diagnosis makes it possible to take measures to preserve hypoplastic teeth before issues such as cavities or stains appear.
Treatment
A dentist may initially monitor the condition of your teeth and recommend treatment only if there is damage or a risk of tooth damage.
Depending on the situation, treatment may include:
- enamel remineralization, which adds minerals to the teeth to help strengthen enamel;
- dental bonding, which involves applying a tooth-colored resin material to the teeth;
- crowns, tooth-shaped caps that cover and protect weak or damaged teeth;
- dental fillings, materials that fill the empty space after a dentist removes decay, which can also restore damaged areas of teeth;
- veneers, thin coverings placed on the front surface of the teeth to conceal imperfections such as discoloration or chips.
Can enamel hypoplasia be corrected?
Although enamel is strong, it cannot regenerate on its own like other tissues in our body. It is impossible to completely eliminate a condition such as enamel hypoplasia, but it can be managed with the help of a dentist.
Tooth enamel is a strong protective layer that allows us to chew hard foods and consume hot or cold foods without feeling pain. However, once enamel is lost, it cannot grow back. That is why treatment focuses on preserving the remaining enamel and strengthening the teeth.
A dentist may recommend ways to protect and preserve teeth if you have enamel hypoplasia.
This may include:
- regular professional dental cleanings (twice a year);
- treatment of conditions that may wear down teeth (such as bruxism);
- maintaining proper oral hygiene, including brushing teeth twice a day and daily flossing;
- consuming foods that contain vitamins necessary for strong teeth (such as vitamins A and D); consuming foods or drinks high in calcium (such as cheese and milk).
Foods to avoid
Avoid or reduce the consumption of foods and drinks that can stain or damage enamel. These include:
- sugary foods, including candies and starchy foods that can stick to the teeth;
- sugary drinks such as sweet sodas and fruit juices;
- foods or drinks that cause dry mouth, such as coffee, tea, and alcohol;
- acidic foods, including citrus fruits.
A dentist can review your diet with you and recommend alternatives that are less harmful to your teeth.
Enamel hypoplasia is a lifelong condition that you and your dentist need to monitor carefully. However, having less enamel does not mean that you cannot have healthy teeth. Ask a dentist at the YAREMA DENTAL clinic about ways to preserve enamel and about procedures that can improve the appearance of your teeth if you feel self-conscious about your smile.
