Introduction to Polydontia: What is it?
Derived from the Greek words "poly" meaning many and "dont" meaning tooth, Polydontia refers to the occurrence of supernumerary teeth, which are additional teeth that are more than normal dental formula.While most individuals develop a set of 20 primary (baby) teeth and 32 permanent teeth, Polydontia introduces a fascinating anomaly where the dental arches harbor an excess of these dental structures.
These supernumerary teeth can manifest in various forms, ranging from small, rudimentary structures to fully developed, functional teeth.
The prevalence of Polydontia varies among individuals and populations, with some estimates suggesting that it affects 0.1% to 3.9% of the global population.
Although the exact causes of this condition are not yet fully understood, researchers propose that a combination of genetic factors and environmental influences play a role in its development.
Polydontia can manifest in different patterns, such as-
Supplemental teeth
• Resemble the normal dentition
• Conical-shaped teeth
More complex forms –
• Tuberculate
• Odontome
• Geminated teeth.
Location –
Additional teeth can appear in any region of the mouth, including the incisors, canines, premolars, or molars, disrupting the usual dental arrangement.
Dental Issues / Complications –
While the presence of extra teeth may seem intriguing, it is important to note that Polydontia can lead to a variety of dental issues.
• Crowding
• misalignment of teeth,
• impacted teeth,
