Snakes' Unique Dental Secrets Unveiled
February 2023
King's College London
Introduction
Dive into the slithery world of snakes with King's College London's latest discovery! Researchers have unraveled how snakes uniquely replace their teeth, unlike any other reptile. Forget the usual 'replacement pit'—snakes use special cells to internally break down old teeth, making room for new ones. This fascinating study not only sheds light on snake dental hygiene but also traces this toothy trick back to ancient snakes, using high-tech scans to peek inside fossils.

Unveiling the Secrets of Serpentine Smiles
Imagine having a set of teeth that could replace themselves whenever they got old or worn out. No more dentist visits for cavities or broken teeth! While this might sound like something out of a science fiction story for us, it's a reality for snakes. The recent discovery about how snakes replace their teeth sheds light on the remarkable adaptability and evolutionary success of these creatures. Understanding the mechanisms behind snake tooth replacement not only fascinates us with the complexity of nature but also has implications for dental research, potentially influencing future dental treatments for humans. This topic connects to you because it opens up a world where biology, evolution, and potentially even medical science intersect, showing how discoveries in one area can have far-reaching implications across various fields.

Odontoclasts
Specialized cells that break down tooth tissue, playing a crucial role in the unique way snakes replace their teeth.
Dentine
The hard, dense, bony tissue forming the bulk of a tooth beneath the enamel.
External tooth resorption
A process where a new tooth’s growth leads to the creation of a ‘replacement pit’ that helps in shedding the older tooth, common in most reptiles but not in snakes.
Computerized Tomography (CT) Scanning
A medical imaging technique that allows the inside of an object to be visualized non-invasively by assembling a series of computer-processed X-rays.
Evolutionary tree
A diagram showing the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.
Fossil
The remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock.
