Why does your mouth stink?

Oral hygiene: Poor dental hygiene, such as infrequent brushing and flossing, can allow bacteria to build up in the mouth and cause bad breath.

Dry mouth: Saliva helps to wash away bacteria and food particles from the mouth. When the mouth is dry, bacteria can build up and cause bad breath.

Diet: Certain foods, such as garlic, onions, and coffee, can cause bad breath.

Smoking: Smoking damages the gums and teeth and can also cause bad breath.

Medical conditions: Some medical conditions, such as diabetes, kidney disease, and liver disease, can cause bad breath.

Medications: Certain medications, such as antibiotics and antidepressants, can cause bad breath as a side effect.
