Bad breath in the morning is normal. Changes that occur in your mouth while you sleep cause morning breath for most people. While you sleep, your mouth becomes dry, so dead cells stick to your tongue and inside your cheeks. When bacteria feed off these cells, the result is a foul odor.

It is normal to have bad breath in the morning but if you think you have constant bad breath or are concerned about the condition, see your dentist. He or she can help identify the cause and, if it’s due to an oral condition, develop a treatment plan to help eliminate it. You should also keep a log of the foods you eat and make a list of medications you take. Some medications may play a role in creating mouth odors. Let your dentist know if you've had any surgery or illness since your last appointment.
Always brush twice a day with fluoride toothpaste to remove food debris and plaque. Brush your tongue, too. Once a day, use floss to clean between teeth.
Joan Haizlip, MSN, Cardiology, answeredYes, it is very common to have bad breath in the morning. Sometimes we call it 'morning breath'. When you sleep, your mouth can become dry. Bacteria stick to your mouth and this causes bad breath. It's important to brush your teeth before you go to bed to prevent any food from sticking to your mouth and gums. This can make your 'morning breath' worse.
