Fewer bacteria and food particles are washed away when saliva doesn’t freely travel throughout your mouth. This may lead to infection.
You have three pairs of large (major) salivary glands. They’re located on each side of your face. Parotid glands, which are the largest, are inside each cheek. They sit above your jaw in front of your ears. When one or more of these glands is infected, it’s called parotitis.
