How much time does it take cover up bad breath?

For how long ?: You can cover up bad breath instantly with some strong mouthwash... But it will only last for a few minutes. You need to determine the cause of your bad breath: smoking, diet, dental problems, and acid reflux are a few of the causes. When was your last dental exam and cleaning? If more than six months, start there, you're way overdue.

See a dentist: In the majority of cases, the cause of bad breath, or halitosis, is the product of bacteria in the mouth. The proper diagnosis is the key to a successful treatment. See your dentist for Halimeter test, diagnosis and bad breath treatment that depends on its cause. Good luck.
