Myth Busters: Mouthwash Edition | Riverside Dentist

As much as we hate to admit it, some of our favorite foods leave us with some of the worst breath. We enjoy our garlic, onions and coffee, and the dragon breath that follows is completely worth it. Pop in a stick of gum and we’re good. What if I told you it’s all a myth, that mouthwash isn’t helping you out with bad breath at all? Sorry to have to break the news, but it’s true.

So, what causes bad breath? While there are a few medical conditions that can cause bad breath, poor dental hygiene is generally what causes everyday cases of it. We naturally produce saliva to help our mouth maintain a healthy pH balance and break up all the built-up bacteria, giving us bad breath.

Okay, let’s look at mouthwash. We know for a fact that mouthwash is full of alcohol, some as much as 25 percent. We also know that alcohol dehydrates us. So, by default, mouthwash is also dehydrating. Now, if mouthwash dehydrates us, we are not producing enough saliva. Not enough saliva, our pH balance is thrown off and bacteria is allowed to collect. Mouthwash is actually doing the complete opposite of what we thought!

Now, what do we do? Drink water. The more you drink, the more saliva you’re producing. Brush and floss a couple times a day, and tongue scrape at least once daily. If you are in a jam, munching on an apple or a stick of gum will do the trick.
