Hello, My first thought would be to check for an oral infection that may contribute to these symptoms. Thrush or oral yeast infections can alter your sense of taste. Your tongue may appear red or have a coating. There may be an imbalance of the natural bacteria in your mouth. Make sure to maintain good daily dental hygiene. Keep well hydrated. Take some acidophilus. Your dentist can prescribe an antifungal medication such as nystatin if necessary. See your dentist to rule out any active dental infections that require treatment. An abscess that drains will affect your sense of taste. Look for any broken fillings, swollen gums or bubbles on the gum that can indicate the need for dental treatment. Make sure you maintain a proper diet with well balanced vitamins. And imbalance can affect the oral environment. Gastric disturbances or an acidic condition have detrimental effects on oral tissue. Your system is out of balance and it may take time for your mouth to re-establish a natural balance. Consider further evaluation of your salivary gland, saliva chemistry and taste buds function if condition persists. Thank you for your inquiry. I hope you begin to feel better soon.
