- •Mouth breathing and snoring reduce saliva production, causing dryness and bacterial growth that results in a severe bitter taste.

Key Questions Answered
A recurring bitter taste in the morning can be caused by acid reflux, liver and gallbladder disorders, dry mouth from nighttime breathing or snoring, poor oral and tongue hygiene, and vitamin B12 or zinc deficiencies.
Eating late at night and sleeping immediately can cause the esophageal valve to relax, allowing stomach bile and acids to travel up through the throat and leave a bitter taste on the tongue by morning.
To prevent mouth bitterness, finish meals 2 to 3 hours before sleep, brush and clean your tongue twice daily, drink at least 3 liters of water, and consume citrus fruits like lemon to increase saliva production.
