A dry mouth can be caused by a variety of factors that include medication side effects, dehydration and medical conditions such as diabetes, with symptoms that include excessive thirst, foul breath and dry throat, explains WebMD. Additional causes of dry mouth include smoking and damaged salivary glands.
Individuals with dry mouths may also experience symptoms such as cracked lips, tongue roughness, oral infections and swallowing difficulties, explains the National Institute of Dental and Craniofacial Research. In certain cases, the condition can occur following head and neck injuries, as the injuries can lead to nerve damage that hinders communication to the salivary glands, causing them to produce less saliva.
Home remedies that may help to relieve symptoms of dry mouth include chewing on sugarless gum or sucking on sugarless candies to increase salivary production, avoiding medications such as antihistamines and decongestants, taking small sips of water on a regular basis and quitting smoking, explains Mayo Clinic.
Individuals with dry mouth symptoms may also find relief by rinsing with mouthwashes that contain moisturizing ingredients such as hydroxyethyl cellulose. It is important for individuals with chronic dry mouth that does not improve with home remedies to consult with a physician in order to determine if an underlying cause is responsible for the symptoms, advises Mayo Clinic.
