Onion breath can last up to three days due to particles staying in the bloodstream. Flossing, brushing teeth, drinking water, and eating parsley can help neutralize the smell. Mints can mask any remaining odor.
While many types of bad breath can be remedied with a mint, piece of gum, or brushing your teeth, this is often not true with onion breath. That’s because, when you eat this root vegetable, the particles that give off the characteristic smell of an onion stay in your bloodstream for up to three days, meaning that every time you exhale, it smells like onions. To eliminate this problem, floss your teeth thoroughly and brush your teeth. Make sure you drink plenty of water, and try eating foods with parsley or just plain parsley, as this herb can help neutralize some of the onion smell. While these steps will likely improve your onion’s breath, you’ll probably need to patiently wait for it to go away on its own and use mints to mask any remaining odor.
You can take the breath away from onion breath by flossing and brushing your teeth thoroughly. Flossing is perhaps the most important, as any small pieces of onion stuck in your teeth will only intensify the smell. When brushing your teeth, make sure you clean your gums as well, as this can strip some of the oil from the onion causing bad breath, and remember to brush your tongue. If you have a specialized tongue scraper, using this can be helpful.
The human body is constantly producing saliva, which helps cleanse the mouth; however, to do this, the body needs a lot of water. After flossing and brushing your teeth, drink as much water as you can on an ongoing basis. Not only will this help rinse out your mouth, but it will also help your body produce more saliva, shortening the amount of time you feel the onion breath.
Parsley, a common herb that can be easily found in most grocery stores or farmers’ markets, contains oils that produce a scent that can neutralize that of onions. Chewing on a piece of parsley and eating foods containing large amounts of it, such as a salad that uses parsley as a green, can help relieve bad breath. If possible, opt for flat-leaf parsley, often referred to as Italian parsley, as it tends to contain more neutralizing oils. In the future, adding parsley to any foods that contain onion may help eliminate some of the bad breath problems associated with its consumption.
While all of these ideas may help relieve onion breath, you may have to wait until the oils leave your bloodstream. These tips and tricks, however, will help reduce the time you experience onion breath and can temporarily mask any residual odor. Also, chewing peppermint gum, using breath mints, or rinsing regularly with a mild mouthwash can help hide the smell until the onion is out of your system.
