Why might your breath suddenly start to smell?

* Eating certain foods: Some foods, such as garlic, onions, and coffee, can cause your breath to smell bad. This is because they contain compounds that are broken down into smelly gases when they are digested.

* Poor dental hygiene: Not brushing and flossing your teeth regularly can lead to a build-up of bacteria in your mouth, which can cause bad breath.

* Dry mouth: Dry mouth can also cause bad breath because it reduces the amount of saliva in your mouth, which helps to wash away bacteria and food particles.

* Gum disease: Gum disease is a serious infection of the gums that can cause bad breath, bleeding gums, and loose teeth.

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

* Medications: Certain medications, such as antibiotics and antidepressants, can cause dry mouth, which can lead to bad breath.
