What is Microdontia?

What is the normal size of the teeth?

To achieve a perfect smile all the components of your mouth must be in balance and harmony. This includes the shape of the lips, the length of the gums, the alignment and size of the teeth. The measures of the teeth vary, therefore, there is no normal size of the teeth, but a range. In fact, there are many theories and results found by experts in the area regarding the dimensions of different types of teeth.

Learn about microdontia

It is said that a patient presents microdontia when the size of their teeth is considerably smaller than the rest of the elements that make up the mouth. The roots of the teeth are of normal size. But crowns turn out to be much smaller than usual. This is known as root dwarfism.

What is Microdontia


There are two types of microdontia, these are:

  • Partial: It is the most common type. It occurs when only one or some of the dental teeth are smaller than the rest. This anomaly is mainly noticed in the upper lateral incisors, then in the third molars and in the premolars. In general, in this type of microdontia, teeth can have alterations in their shape.
  • Generalized: Generalized microdontia is very rare. It occurs when all dental teeth where a size less than normal. In these cases, hereditary factors, such as dwarfism are those that affect the dental structure.
  • Relative: When the patient has a large jaw that makes the teeth look smaller, it is said to have relative microdontia.

Possible solutions to the microdontia

One of the most relevant consequences of microdontia is that it affects the aesthetics of your smile due to the uneven size of the teeth. But this can be corrected by the following treatments:

  • Aesthetic veneers: One of the best options is the placement of veneers on the teeth that are more visible. These can be porcelain or composite.
  • Dental crowns: The advantage of crowns is that they can be tailored to the tooth to improve their size and shape. This process can be a partial or total restoration.
  • Restorations: With the use of composite resins a specialist can restore the tooth that presents the anomaly. As long as the difference in size is not too large.

Sometimes the teeth are not in their corresponding position due to the deficit in the size of some. That is why specialists must resort to orthodontic treatments to complement and improve results.
