What causes microdontia?

A disorder characterized as having abnormally small teeth, microdontia can occur in adults and children. Generally, something in one’s genetics tends to pass down microdontia, while other known causes link dwarfism, cleft palate, Down syndrome, and hormonal imbalances to microdontia.

What is true microdontia?

So, the word ‘microdontia’ means having small teeth. A person who has one or more teeth smaller than normal is said to have a case of microdontia. Such small teeth are called, by specialists, microdontic teeth or simply microdonts. Microdonts can have normal or abnormal morphology.

What is partial microdontia?

Partial microdontia: Refers to only some of your teeth having a small size. Generalized microdontia: Refers to all of your teeth having a small size. Relative microdontia: Refers to average-sized teeth appearing to be small relative to those with a large jawbone.

What does Macrodontia mean?

Total: Total macrodontia or macrodontism is an anomaly that occurs when all teeth are larger than usual. It is related to disorders such as gigantism and hemihypertrophy.

How common is microdontia?

Microdontia is a type of dental anomaly in which teeth are smaller in size than normal. This abnormality can occur in permanent teeth and primary teeth. According to epidemiological studies, the prevalence of microdontia ranges from 1.5 to 2% and occurs more frequently in females than males.

Is microdontia hereditary?

Microdontia usually results from both inherited and environmental factors. The conditions associated with microdontia include: Pituitary dwarfism.

How do I fix microdontia?

3 Ways to Correct Microdontia

  1. Veneers – A dental veneer will fit over the top of your existing teeth, and they cover the front portion.
  2. Crowns – Crowns can be used to make your tooth stronger while it improves the appearance.

Can microdontia be fixed?

A dentist can discuss possible solutions like veneers or crowns that can fix or treat the issue. In some cases, microdontia can also be a sign of a larger health issue that may need addressing. If you notice other unusual signs or symptoms, discuss the issue with a doctor or your child’s pediatrician.

How do I know if I have macrodontia?

A dentist can diagnose macrodontia by performing a dental exam and taking X-rays of your teeth. After they make a diagnosis, your dentist will recommend a specific course of treatment. If they can’t find any cause of your enlarged teeth, they may recommend that you visit a cosmetic dentist.

Is microdontia genetic?

Some individuals have teeth that are not only short but are also smaller in general and may look more like baby teeth than adult teeth. This is known as microdontia and is usually caused by a genetic condition. There are three different types of microdontia.

How do you fix macrodontia?


  1. Orthodontics. Orthodontics can help straighten your teeth and expand your jaw if necessary.
  2. Teeth shaving. Another cosmetic option for those with macrodontia is to try teeth shaving.
  3. Teeth removal. Removing some teeth can help space out existing teeth in the mouth.

How do I know if I have microdontia?

Relatively generalized microdontia is when someone does not actually have small teeth, but their teeth appear smaller than usual because their jaw is larger. Finally, localized microdontia is the most common form. This is when only one tooth is small, often an upper lateral incisor or third molar.

What are the syndromes associated with severe microdontia?

Severe and generalized microdontia is associated with several syndromes. Rieger syndrome, an autosomal dominant genetic defect, whose main features are ocular (microphthalmia), craniofacial (hypoplastic alae nasi) and hypospadia, presents with, in addition to hypodontia, an anterior mandibular tooth of smaller size and tapered in shape.

What is generalized microdontia?

Truly generalized microdontia, on the other hand, involves all the teeth of the patient. A normal sized tooth would be an exception. Truly generalized microdontia is rare. The condition may be caused by pituitary dwarfism or Down’s syndrome.

Which teeth are involved in localized microdontia?

The most commonly involved tooth in localized microdontia is the maxillary lateral incisor, which may also be shaped like an inverted cone (a “peg lateral”). Peg laterals typically occur on both sides, and have short roots. Inheritance may be involved, and the frequency of microdontia in the upper laterals is just under 1%.

What are myoclonic seizures?

Myoclonic seizures consist of sudden body or limb jerks that can involve the arms, head and neck. The spasms occur on both sides of the body in clusters, especially in the morning. When these seizures develop in adolescence along with tonic-clonic seizures, they are part of a syndrome called juvenile myoclonic epilepsy.
