Trioral is supposed to work continuously for 24 hours and be even more effective than normal mouthwash and brushing your teeth and tongue. It is supposed to be some new technology. Supposedly, it binds to any bacteria that are in your mouth and don't let them produce sulfur. It is also supposed to prevent morning breath completely. We'll see...yes, it's expensive, but I really have to do something about my ridiculous gum chewing habit. I already brush my teeth and tongue three times per day, floss once a day and use regular mouthwash.
