to clean nasal cavities of mucous

You Have Allergies

A drippy nose can make your breath smell sour.

When nasal fluid drips from the sinuses to the back of your throat, it can stink up your breath. So canbreathing mainly from your mouth when nasal passages are blocked because this dries out your mouth. A dry mouth prevents saliva from keeping your mouth moist and clean, making dead cells more likely to accumulate on your tongue, gums, and cheeks. When these cells decompose, they produce an odor.

Fix it: Drink plenty of water—not coffee, soda, or alcohol, which can dehydrate you. Decades worth of clinical tests have also found that nasal irrigation, in which the sinus cavities are rinsed with lukewarm salt water, is a safe, effective, and inexpensive way to flush out the mucous that causes halitosis. Rubber syringes, ceramic Neti pots, a plastic squeeze bottle such as SinuCleanse, or sprays like ENTsol all work well. Use warm, distilled water and 1/4 teaspoon of kosher salt per 1 cup for the Neti pot.
