Full Answer

Some causes of decreased ability to swallow or retain saliva in the mouth include allergies, acute sinusitis, enlarged adenoids and tumors that affect lip or tongue movement, states Mayo Clinic. Certain conditions decrease a person’s ability to swallow or keep saliva, as they affect muscle coordination and the function of the oral cavity.

WebMD explains that excessive saliva is typically not a serious problem unless it persists. People normally produce more or less saliva depending on the foods and beverages they consume. The body tends to swallow more to take care of excess saliva. A person makes too much saliva when he has problems swallowing and when one or more salivary gland is overactive. It is normal for the salivary glands to become overactive when a person eats very spicy foods. However, when excessive saliva occurs all the time, it is important to consult a healthcare provider as it can be a result of a medical condition or a side effect of a medication.
