Macrodentia

Macrodentia is a rare hereditary disease in which teeth are significantly larger than normal. Macrodontia can be associated with various genetic disorders, including Down syndrome, Klinefelter syndrome, and others.

The disease manifests itself already in infancy, when teeth begin to grow. In most cases, the upper central incisors are noticeably larger than the lower ones. However, in some cases other teeth may be enlarged.

Macrodentia can lead to various complications, including speech and swallowing problems, problems with teeth and gums, and malocclusion. Treatment may include removal of excess teeth, bite correction, and orthodontic treatment.

It is important to note that macrodentia is a hereditary disease, and if one of the parents had such teeth, then the probability of developing the disease in the child is about 50%. However, even if the child does not have obvious signs of macrodentia, it is recommended to consult a dentist for a preventive examination and consultation.



Macrodentia is a term used in dental practice to describe teeth that are greatly enlarged. It can occur in both children and adults. In this case, there is a significant deviation from the normal standard of dentition and a significant disproportion between the teeth of the upper and lower jaw, or asymmetry in relation to each other. An increase in the dentofacial organ is observed by more than 50% of the norm in two or more parameters. In the last stage, called megalodontia, there may be a complete lack of control over the position of the jaws and their anatomy, extremely limited chewing ability, insufficient protection of the oral cavity from bacteria, and difficulties in caring for the teeth. Macrogenism is often accompanied by other problems in the body, such as increased stress levels and psychological problems. There are active and passive development of the disease. In the first case, the disease is provoked by congenital genetic pathologies and mutations during fetal development.

There are factors that can cause macrodentia: - Hereditary predisposition. Improper metabolism. Unbalanced nutrition of parents during pregnancy affects the development of the child. Therefore, to avoid diseases in little people, you should monitor the diet and health of the parents; - Infectious diseases. This includes measles, tuberculosis, scarlet fever, diphtheria, syphilis and others. Due to these diseases, teeth enlarge not only due to pathogenic bacilli, but also against the background of weakened immunity; - Radioactive exposure; - Autoimmune diseases, for example, Graves' disease. Rarely, changes in dental bite occur while taking strong medications. But even if they are treated correctly, therapeutic doses can lead to microstomia, which causes teeth to enlarge; - Insufficient attention on the part of parents to the child’s health;

Thus, macrodentia may be caused by genetic predisposition, metabolic disorders, infectious diseases at an early age, malnutrition, or taking certain medications, which can lead to the development of microstomia.
