Mouth Breathing
The production of saliva is reduced at night. That’s why we often wake up with a rotten smell and taste in our mouth, even after thorough flossing and brushing. Snoring and mouth breathing would further dry out your mouth and make your breath smells even worse. Also, this condition might be harmful because it would cause hoarseness, sore throat, changes in tastes, and difficulty swallowing and speaking. The solution is to drink a lot of water and brush your teeth regularly. [6]
