Just remember: If it's a short-term problem, take comfort in employing a short-term solution. If your bad breath is the result of food particles or dry mouth, stimulate saliva production to help wash away bacteria and freshen breath. Make sure to brush, floss and use a mouthwash daily. A mouthwash like Colgate® Plax® will help kill the bacteria in the entire mouth including the back of the tongue, keeping breath fresh.
If your bad breath is the result of a chronic issue such as tooth decay or an illness, you'll need to see a health care professional because gum and mouthwash will only mask the problem for a little while. If you have a dental problem, make an appointment with your dentist. If you think the problem may be internal, you'll need to see your family doctor.
