If a thorough brushing and a breath mint aren't working to combat foul breath, you could be suffering from a dangerous ailment that, if left untreated, could harm your teeth, mouth, and gums.
Xerostomia is the name for this condition. Medications, sometimes known as dry mouth, are one of the most common causes of the condition.
More than 400 prescription drugs, including some created for asthma treatment, depression, and cholesterol reduction, can cause xerostomia, a disorder that is a primary cause of halitosis, according to the National Institute of Dental and Craniofacial Research (bad breath). Cracked lips, cavities, bleeding gums, and canker sores are all symptoms of the illness, which can lead to a decline in oral and dental health. Xerostomia can be fatal in severe situations.
