Hello, your dry mouth will produce most of the symptoms that you have noted. Gasrtic disturbances affect the oral environment as well. Many medications cause the side effect of a dry mouth. Try to get your blood pressure under control and balance your over all health to a steady state. Give your body a chance to adjust. Keep well hydrated and drink a great deal of water. Nutrition correct for your medical history should be a primary concern. Vitamin B12 can be helpful. Avoid irritants such as alcohol, smoking, acidic and spicy foods. Rinse with warm salt water. Try to use dental products designed for a dry mouth. You will be able to find gum, toothpaste, rinse and sprays. Make sure that you have a recent dental exam. An increase in decay can be another side effect. Your plaque and saliva consistency can change which makes keeping your mouth clean more difficult. Brush your tongue. Your dentist will check for an oral yeast infection and treat with the prescription NyStatin if necessary. Thank you for your inquiry. I hope my comments are helpful and offer you relief.
