Causes, care and answers to common questions.
Hyperdontia refers to a higher than usual number of teeth. An extra tooth may be visible in the mouth or remain unerupted, so it is sometimes detected only through examinations.
Hyperdontia means there is one or more extra teeth. They can be in the primary or permanent dentition, erupt in different parts of the jaw, or remain within the bone. The extra tooth may differ in shape and size from adjacent teeth.
Sometimes an extra tooth is visible. Other times delayed eruption of a permanent tooth, changed tooth position, or gaps between teeth attract attention. These signs are not specific to hyperdontia, so a dentist’s evaluation is necessary.
The dentist examines the dentition, assesses the eruption process, and if needed, orders an X-ray exam. It helps determine the location of the extra tooth and its relation to adjacent teeth. In some cases, consultation with an orthodontist or oral surgeon may be needed.
An extra tooth may sometimes interfere with another tooth’s eruption or alter its position. The effect depends on location and individual situation: the mere presence of an extra tooth does not necessarily mean complications will occur.
Not always. The decision depends on its position, patient’s age, symptoms, impact on adjacent teeth, and treatment risk. A specialist may recommend monitoring, removal, or another treatment plan; when needed, coordinated with orthodontic therapy.
No. It may remain unerupted and be detected only by imaging.
No. The doctor assesses benefits, risks, and alternatives.
If teeth erupt unusually, an extra tooth is visible, or you have questions about your child’s dentition, schedule an examination.
