how do germs cause tooth decay

1.	how do germs cause tooth decay
Answer» Food and germs(bacteria) can cause tooth decay. Plaque is always forming inside your mouth. This sticky substance is getting on your gums and your teeth, and it contains the bacteria that feast on the sugars from the food we eat. When bacteria feed, they make acid. And that acid can attack your teeth well after you are done eating, and over a long enough period of time they can start to destroy tooth enamel. Left untreated, decay will work its way throughout your entire tooth and all of its layers. You may not notice pain or sensitivity until decay goes through your tooth enamel and into the dentin layer, which can become irritated by hot or cold foods and drinks. There are more factors and behaviors that can make you more likely to get tooth decay.\xa0
