Bad Breath

What causes bad breath?

Bacteria break down food particles and produce sulfur compounds with a strong odor, especially on the back of the tongue and between the teeth. Gum disease and cavities give those bacteria more places to collect, and a dry mouth leaves less saliva to wash them away. Foods such as garlic and onions, tobacco, and some medical conditions, including sinus and digestive problems, can also affect breath.

How does Dr. Lee find the cause?

Dr. Lee examines your teeth, gums, tongue, and any dental work, measuring the gums and taking X-rays if needed to check for gum disease or decay. She also reviews your medications and health history, since some cause dry mouth. When the cause appears to be outside the mouth, she recommends seeing your physician.

How is bad breath treated?

How do daily habits affect breath?

Brushing twice a day, cleaning between the teeth, and cleaning the back of the tongue remove the bacteria that cause most odors. Drinking water helps keep the mouth moist between meals. Regular professional cleanings remove the tartar that brushing cannot.

When should you schedule an evaluation?

Schedule an evaluation if bad breath lasts despite brushing and flossing, or comes with bleeding gums or a bad taste. Dr. Lee will look for a dental cause and explain the next step if the cause lies elsewhere.
