Microbe Mouth

Anna Dumitriu worked with scientists Melissa Grant and Rachel Sammons at the University of Birmingham to create “Microbe Mouth” (2016) made from unique teeth grown using bacteria. The team literally grew teeth, or at least the hydroxyapatite that tooth enamel is made from, in the lab using an extremophile bacterium which is part of the species called Serratia (Serratia N14).

“Microbe Mouth”

These bacteria were originally found in highly polluted sites near mines and can even survive in radioactive environments due to the mineral they produce which acts as a kind of shield for them.

They are also being looked at for uses in so-called bio-remediation projects, where bacteria can be used to remove harmful substances from the environment. They are not harmful to humans, but are we ready for teeth made from microbes?

Science Gallery London workshop

The team ran a series of workshops where participants glazed their own ceramic teeth in unique ways, using glazes derived from various bacterial species which live in our mouths and cause tooth decay and gum disease. 

Bacteria used included Porphyromonas gingivalis that can introduce an iron containing light brown stain to the glaze. In these workshops, visitors also had a chance to delve into bacterial world of the mouth, learning more about healthy and unhealthy mouths.
