Hypodontia Causes
- Can be environmental or genetic
- May be isolated or associated with syndromes such as ectodermal dysplasia and Down syndrome
Diagnostic Method
- Dental panoramic tomograph screening is used
- Screening should be done no earlier than 9 years of age
Prevention
- No specific prevention methods identified
Treatment
- Focus on preventing tooth loss due to caries, periodontal disease, and trauma
- Requires a multidisciplinary approach involving pediatric, orthodontic, and restorative specialties
- Management varies depending on the stage of dental development
Hypodontia Overview
- Developmental absence of one or more teeth, excluding third molars
- Common dental anomaly with negative impact on function and appearance
- Rarely occurs in primary teeth, with adult second premolars and upper lateral incisors most commonly affected
- Often part of a syndrome requiring multidisciplinary treatment
- Can be classified as hypodontia, oligodontia, or anodontia based on the number of missing teeth
Signs and Symptoms
- All baby teeth should be present by age three
- Adult teeth typically erupt between ages 6 and 14, except for wisdom teeth (third molars) which erupt between ages 17 and 25
- Panoramic x-rays are taken if a tooth has not erupted by the appropriate age
Dental Features
- Microdontia, where teeth appear smaller than normal, may be present in one or more teeth
- Microdontia can be genetically linked and may be associated with ectodermal dysplasia, cleft lip or palate, or Down syndrome
- Delay in tooth development can indicate hypodontia, as the absence of an adult successor slows down the normal resorption of baby teeth roots
Misplaced Teeth

Hypodontia is defined as the developmental absence of one or more teeth excluding the third molars. It is one of the most common dental anomalies, and can have a negative impact on function, and also appearance. It rarely occurs in primary teeth (also known as deciduous, milk, first and baby teeth) and the most commonly affected are the adult second premolars and the upper lateral incisors. It usually occurs as part of a syndrome that involves other abnormalities and requires multidisciplinary treatment.
