Investigating the Effect of Different Teeth Cleaning Agents on the Growth of Bacteria On account of the price and variety of tooth cleaning agents available on the market, an investigation was conducted into the effect of different tooth cleaning agents containing different ingredients on the growth of teeth bacteria. The tooth cleaning agents tested were Colgate total antibacterial toothpaste with Triclosan (3 pence/ml), Boots non fluoride toothpaste (less than a penny/ml), Dental care baking soda toothpaste (2 pence/ml) and a twig from a natural toothbrush tree Salvadora persica commonly known as ‘Muswak’ (30 pence for two weeks supply, toothbrush not required as twig carries out the function of a toothbrush).

Five small wells were cut into a solidified agar plate at approximate
