To help relieve symptoms of dry mouth, you may want to drink fluids that do not contain sugar or acids, with water being the best. You also may want to use sugar-free hard candy or gum to stimulate saliva flow. Many people have also found some relief using over the counter saliva substitutes.
Chronic dry mouth (xerostomia) is caused by lack of saliva for a long period of time. Multiple causes for this condition include: medications, chronic diseases, and certain medical treatments. Chronic dry mouth is not only uncomfortable, but it increases your risk for dental decay and makes it difficult for dentures to fit properly.
If you suffer from dry mouth, you should visit your prosthodontist more frequently than every six months to address your increased risk of tooth decay.
