Immune cells may play a role in causing cavities
We owe our lives to our immune systems – without it, even the most minor of sniffles could be fatal. But the immune system makes mistakes too, with the results ranging from allergies to multiple sclerosis. Now, researchers at the University of Toronto have found that cavities might also be collateral damage from an overzealous immune system.
Traditionally, bacteria have taken most of the blame for cavities and tooth decay. The bugs cling to your teeth as plaque and produce acid as waste, which dissolves tooth enamel, dentin and even filling material.
