Oral microbiology is all about the tiny living creatures called bacteria that live in your mouth. You have lots and lots of bacteria in your mouth - they are so small, you can’t see them without a microscope!
Some of these bacteria are good and help keep your mouth healthy by breaking down food particles and fighting off harmful germs. But some bacteria can be bad and cause cavities, gum disease, and other oral health problems.
Brushing your teeth, flossing, and visiting the dentist regularly can help keep your mouth healthy by controlling the amount of bacteria in your mouth.
Scientists who study oral microbiology look at the different types of bacteria that live in your mouth and how they interact with each other and with your body. They use their knowledge to develop new ways to treat and prevent oral health problems.
