Microdontics – What It Is, Causes, Symptoms and Treatments


Microdontics – What is the most appropriate Causes, Symptoms and Treatments  to deal with this condition. In addition, the anomalies of tooth size and shape are common in the presence of clinical medicine tooth. Among them is microdontics, which is one of the most frequent anomalies and is a condition in which the teeth  are smaller than normal size and may involve all teeth , being limited to a single tooth or a group of teeth .

Between 4% and 15% of the world population has some problem related to the lack or abnormal growth of one or more teeth , especially permanent teeth .

What is Microdontics:

‘Micro’ means small and ‘dontia’ means a state related to teeth . So the sudden word “microdontics” means to have small teeth . A person who has one or more  smaller teeth than normal is said to have a case of microdontics. These tiny teeth are called, by experts,  microdonic teeth or simply microdons.

Microdons may have a normal or abnormal morphology. They may have a regular shape but a small size, or they may be regular size and have a triangular shape. In many cases, these small teeth  have small roots, while the crown may be almost normal.

Causes of Microdontics:

The causes of these failures are still unknown. Genetic or environmental factors that influence tooth development are assumed . Some authors consider that a combination of multiple genetic and environmental factors is necessary for these anomalies to occur.

Types of Microdontics:

There are basically three types of microdontics : true generalized microdontics, relative generalized microdontics, and localized microdontics.

Truly Generalized Microdontics:  True generalized microdontics is the type of microdontics in which all teeth  appear smaller than normal size. It is very rare and is commonly related to pituitary dwarfism.

Relative Generalized Microdontics: Relative generalized  microdontics is the type in which all teeth  appear at normal size but appear smaller than the enlarged jaws. This type is the result of genetically passed large jaws forming one parent and the normal size of  the other teeth .

Localized Microdontics:  The latter type is localized microdontics, which is also called pseudo or focal microdontics. The localized one is the type in which one tooth is smaller than other  normal sized teeth .

Compared to generalized, localized is a more common case. It is also usually associated with hypodontics, a condition in which the number of teeth  is less than the normal average count.


Diagnosis of these malformations can be made by clinical examination at the dentist with the help of radiographs. It brings two main problems; the aesthetic and the functional. With the diastema problem (spacing) can arise problems in the teeth fitting  (occlusion) and also misalignment. In this case, it is indicated the use of orthodontic appliances to close the spaces or adjust them to receive restoration.

Microdontics Symptoms:

Patients with this syndrome have severe prenatal and postnatal growth retardation, with a head size relatively proportional to birth, but extreme microcephaly in adulthood. The impressive dental anomalies consist of teeth extremely small, teeth  opalescent and abnormally formed and molars without roots. The teeth are spontaneously exfoliated because the alveolar bone is severely hypoplastic.

Microdontic Treatments:

It is a treatment not very common and relatively little studied which generates a certain ignorance even on the part of dentists, but as is seen more than macrodontics, already has a larger number of dentists who work very well with the case.


The best thing to do is to look for a trusted dentist and get the exams ordered by him who will decide between a few options like:

Use orthodontic braces to correct the consequences that this tooth causes.

Perform occlusal adjustments and maintain the tooth  as best as possible without tearing or using orthodontic aparatology (in simpler cases).

Make aesthetic adjustments to the tooth , making it necessary to completely cover the tooth  with materials such as resin or porcelain.
