“My first tip is to minimize snacks, especially sugary or acidic ones, and brush every time—yes, every time—you put food in your mouth, unless that food is celery or cucumber. Bacteria sticks to your teeth within 20 minutes of your teeth being exposed to sugary substances, releasing destructive acids and toxins.
Secondly, drink water throughout the day. This will not only directly rinse your mouth but it will keep your saliva thin so it can do a better job of cleansing your mouth continuously.
Lastly, always breathe through your nose. If you find that your lips are frequently apart, you are likely also breathing through your mouth. Mouth breathing dries out your mouth, making your saliva viscous and inefficient at cleansing your mouth. This creates an environment conducive for bacterial growth which increases the likelihood of tooth decay, gum disease and bad breath.”
