Brushing alone isn't enough to keep your teeth clean and your gums healthy. According to the American Dental Association (ADA), incorporating mouthwash into your daily routine also allows you to clean tiny crevices in your mouth that cannot be reached by a toothbrush. However, most conventional mouthwash formulas contain harmful ingredients, such as fluoride, alcohol and saccharin, which are bad for your oral health and can actually do more harm than good. Keeping your mouth moist and pH balanced is crucial for maintaining good oral health. Most mouthwashes fall below a 5.5 pH which makes your mouth extremely acidic and can lead to a dry mouth, bad breath, and even cavities.
