A not so fun fact: there are over 700 different species of bacteria that can grow in our mouths (ew, we know). Reading that number is alarming enough but the worst part is that brushing alone can’t kill them all so using a mouth rinse with antibacterial ingredients is key. One of my favorites: Colgate Total Advanced Pro-Shield Mouthwash ($5, drugstores). It’ll not only wipe out 99% of the bacteria, but it also protects your teeth and mouth from germs for up to twelve hours, even after eating and drinking. I felt like I had an invisible shield on my teeth all day after using it. Also good to note, it didn’t give me that harsh, burny feeling. * Colgate Total Advanced Pro-Shield Mouthwash was given to us by Colgate-Palmolive for review purposes.
