Some foods and drinks that can cause bad breath include garlic, cumin, high-sugar foods (especially if they happen to be sticky), energy drinks and coffee.
“The bacteria that cause the foul odors in your mouth love sugar, so the more sugar they get, especially over a longer period of time, means they can produce lots of odor-causing by-products,” Philipp added.
Masking agents such as gum and mints should be sugar-free, otherwise they can make bad breath worse after the sweet smell runs out, he said.
Also, make sure to get only alcohol-free mouth wash, since mouth wash containing alcohol can dry out your mouth and prevent saliva from washing away food and bacteria, Philipp said.
If possible, make sure to brush your teeth after eating, he added. If you can’t, then at least rinse your mouth with water.
Dr. David G. Genet, a periodontist in Aventura, Florida said in an email that bad breath either comes from the oral cavity or the gastrointestinal system.
Some additional causes of bad breath in the mouth include dental cavities, poorly-fitting dentures, and bacterial overgrowth on the tongue and mucous membranes, Genet said.
Onions can also lead to bad breath. The scent will only leave once the onion is completely digested, he said.
Genet suggested scraping the tongue and brushing teeth with fluoride toothpaste twice a day, as well as flossing.
