If you've ever wondered why your breath smells so bad in the morning, there's a simple reason--your mouth is dry. "Morning breath" is a normal and temporary form of halitosis, says the Columbia University College of Dental Medicine. However, dry mouth that lingers for a long time may have another cause and require a doctor's care.
Cause of Bad Breath
Bad breath is caused by the bacteria that grows in your mouth, attaching itself to residual food particles on your tongue, between your teeth and on your gums and teeth. Brushing your teeth twice a day and flossing at least once a day helps to rid your mouth of bacteria. However, during your waking hours, your saliva also helps to wash way residual food and other odors, states the Columbia University College of Dental Medicine.
Dry 'Morning' Breath
Whenever you sleep, your salivary glands slow down production. When you wake in the morning, your mouth feels dry and tacky, your saliva thick and viscous. A dry mouth permits dry or dead cells to adhere to your tongue and the insides of your cheeks, explains the Columbia University College of Dental Medicine. The bacteria in your mouth breaks these down and in the process, produces an unpleasant odor. Morning breath is only temporary; however, dry mouth, also known as xerostomia, can cause more serious problems, according to MayoClinic.com, causing dental decay, decreased taste and difficulty swallowing.
Other Causes of Dry Mouth
A dry mouth---and bad breath---can be caused by other things than a good night's sleep. MayoClinic.com states that there are literally hundreds of medications that cause your mouth to become dry as a side effect. The elderly, who are more likely to take these medications, may be more at risk for xerostomia. Cancer drugs, nerve damage, tobacco use and certain medical conditions, such as Parkinson's disease, diabetes and anxiety disorders, may also cause xerostomia.
Treatment Options
When dry mouth is caused by medication, your doctor may adjust your dosage or switch you to another medication, according to MayoClinic.com. Your doctor may also recommend taking a prescription medication that makes you produce more saliva.
Other Remedies
In addition to brushing your teeth at least twice a day, you can take simple steps to reduce dry mouth symptoms at home. Avoid nonprescription antihistamines and decongestants. Cut down on your caffeine intake, as this can also result in a dry mouth. Sip on water and suck on a sugar-free mint or gum to stimulate saliva production. If you smoke or use a tobacco product, quitting can also help reduce dry mouth symptoms and bad breath, according to MayoClinic.com.
