1. Certain Foods Can Contribute to Bad Breath
Certain foods and bad breath often go hand in hand. The food particles left in your mouth after eating can increase harmful bacteria and lead to bad breath.
Specific foods have stronger scents and are more likely to cause bad breath. If you eat a lot of garlic and onions in your meals, this can affect your breath. An easy solution is to limit the strongly scented foods you eat or brush your teeth immediately after consuming them.
2. Digestive Issues Can Cause Bad Breath

There are many different bad breath types you might encounter. A common type is gut breath caused by digestive system issues.
GERD is a condition that produces acid reflux. When gases and reflux are pushed from the stomach into the esophagus and mouth, this can create an unpleasant taste and smell.
You can also develop bad breath when you struggle with digestive issues that interfere with your bowel movements. Visiting a gastroenterologist can help with your digestive system issues and your bad breath.
3. Smoking Will Give You Bad Breath
About 40% of adults who smoke have tooth decay. Smokers are also at risk of developing gum disease and oral cancer.
Besides dealing with these severe oral health conditions, smoking will leave you with bad breath. Quitting is the best way to prevent these issues altogether.
4. Bad Dental Hygiene Is a Common Cause
Having a good oral hygiene routine is often the cause of bad breath. You can resolve this issue in no time, however, by following some simple bad-breath solutions.
Make sure you brush your teeth twice a day and floss daily. This routine will help prevent the build-up of plaque and reduce your risk of developing tooth decay. It will keep your breath smelling fresh too.
Regular dental visits can help you maintain good oral health and prevent more serious issues.
5. Certain Medications Can Cause Bad Breath Too
Many prescription medications can cause dry mouth and lead to bad breath. Make sure you’re staying hydrated to fight against this issue.
Talk to your doctor for recommendations on medications that cause bad breath that won’t go away.
These Are the Top Causes of Bad Breath
