Bad breath can be caused by several factors. It may result from a dental condition such as a cavity, food lodged between teeth, gum disease or infection. It can also be caused by certain foods that affect breath when digested, such as onions, garlic and alcohol. Bacterial presence and tobacco are other factors that can affect your breath. Finally, it can also be a symptom of a more serious health problem.
Make sure you have good dental hygiene, brush your teeth three times a day and use dental floss daily. Don’t forget to also brush your tongue. Mouthwashes can be effective but should not be abused. Talk to your dentist about your bad breath.
