Your son's breath likely smells like onions because he recently consumed foods containing onions. Certain foods, especially those with sulfur compounds like onions, are known to cause bad breath.
The Science Behind Onion Breath
-
Sulfur Compounds: Onions contain sulfur compounds that are released when they're eaten. These compounds are the primary culprit behind the distinctive onion breath.
-
Absorption into the Bloodstream: These sulfur compounds don't just stay in the mouth; they can be absorbed into the bloodstream. This means the smell can be exhaled through the lungs, contributing to bad breath that lasts longer.
According to information found online, sulfur-producing foods like garlic and onions are especially notorious for causing bad breath in kids. The sulfur compounds take up residence in your child's mouth and are even absorbed into their bloodstream.
What Can You Do?
While onion breath is usually temporary, here are some things that can help:
- Good Oral Hygiene: Encourage your son to brush his teeth, floss, and use a mouthwash after eating onions.
- Drink Water: Drinking plenty of water can help wash away food particles and keep the mouth hydrated.
- Wait it Out: The smell will typically dissipate as the sulfur compounds are metabolized and eliminated from the body.
