The parotid glands are the largest salivary glands located near the jaw, just in front of the ears. They produce saliva, which helps in digestion and keeps the mouth moist. Saliva also plays a crucial role in breaking down food and protecting the teeth from decay. These glands can sometimes become swollen or infected, leading to a condition known as parotitis. This can cause pain and discomfort, often requiring medical attention. Maintaining good oral hygiene and staying hydrated can help keep the parotid glands healthy and functioning properly.
