Saliva production is essential for a healthy mouth and fresh breath because it acts as a natural mouthwash, keeping the mouth moist and clean, and slowly washing away any bacteria and debris.
Although dry mouth tends to occur at night, it can also happen throughout the day. When the mouth becomes dehydrated, saliva production naturally slows down, which is what makes it dry and stale-tasting. It then has a rougher texture, making it more hospitable to bacteria and their foul-smelling byproducts.
Additionally, a dry mouth allows for dead cells to sit on the tongue, gums and inner-cheeks. When those cells break down, they can cause foul odors to arise.
The tongue is home to nearly one-third of the bacteria that contribute to bad breath, and any leftover food particles can lead to a foul smell if it isn’t clean. By cleaning your tongue, you can get rid of at least 85% of the bacteria, so try using a tongue cleaner each time you brush your teeth to purge unwanted odor triggers.
