Gums: This image reveals a large number of yellow-coloured bacteria in the gingiva, or gums, of a human mouth
The set includes shots of the pink surface of dental plaque and a blue carpet of bacteria on a yellow tooth, while other images include plaque nestled among the bristles of a used toothbrush.
Alien invasion: This image has been magnified x1000 and coloured to show the plaque-forming bacteria that lurks on teeth
