6. Infection or Dental Issues
An infection in the mouth or gums, including cavities, can stimulate saliva production, leading to drooling. If you have an infection, you may notice pain, particularly while eating, swallowing, or trying to speak. You also may notice swelling, as well as blood while brushing your teeth. If you think you have an infection it is crucial that you visit your doctor or dentist as soon as possible to solve the problem.
