Eliminate the tonsil stones:

If you’ve noticed yourself coughing up small, yellowish chunks from your throat, those might be tonsil stones. While these stones aren’t harmful, they can cause bad breath. They are bacteria and debris that form in the crevices of your tonsils, ranging from small, soft bits to larger, hardened stones. While they’re usually harmless, in some cases, they can lead to infections. To prevent them, try using mouthwash regularly to reduce bacteria in your mouth and floss regularly.
Caring for your teeth is not just about brushing them and using dental floss, or visiting the dentist. Follow these rules to maintain a healthy smile for as long as possible.
