Once again, 90 Day Fiance has come through with some more dental cringe, this time courtesy of “Big Ed”:
While Ed’s motivation for the “gift” is suspect, you can’t totally blame him for thinking that bad breath comes only from poor oral hygiene. After all, 90% of all halitosis  is caused by conditions in the mouth -food debris, infection, gum disease, oral cancers, faulty restorations, and the like.
Another 2% comes from what you put in your mouth: pungent foods, such as onions and garlic, and things like tobacco, alcohol, and drugs. Very low carb/keto diets are also well-known for causing bad breath.
That leaves 8% of cases due to issues beyond the mouth – such Rose’s stomach ulcer  or acid reflux and other gastrointestinal problems. Endocrine and metabolic disorders can lead to bad breath, too, as can some forms of respiratory illness, liver failure, kidney disease and failure, and leukemias.
And this is exactly why you should talk with your dentist about bad breath that doesn’t go away despite good hygiene. They can rule out or treat any dental cause – or observe signs pointing to a potential medical cause.
Oh, and while Ed is correct about the link between gum disease and heart health, that’s just the beginning when it comes to this particular oral/systemic link. Research has also shown a relationship between perio problems and other chronic inflammatory conditions such as diabetes, stroke, kidney disease, rheumatoid arthritis, cancer, and cognitive decline.
And healthy gums need more than toothpaste and mouthwash. You also need to clean between your teeth and along the gumline. That’s where tools such as floss, oral irrigators (Waterpik), proxy brushes, and the like come into play.
Unless you’d like to leave about 40% of your tooth surfaces grungy, of course.
