To manage dry mouth and bad breath, several over-the-counter options can help. For immediate relief, use alcohol-free mouthwashes and artificial saliva substitutes containing carboxymethylcellulose or glycerin. Sugar-free chewing gums or lozenges containing xylitol are excellent for stimulating natural saliva production. For bad breath, antibacterial mouthrinses containing cetylpyridinium chloride or zinc can help neutralize odors. If these over-the-counter options are not sufficient, a doctor can prescribe medications like pilocarpine or cevimeline to stimulate your salivary glands. Stay well-hydrated by drinking water throughout the day, and consult your doctor or dentist if symptoms persist.
