I've always thought mouthwash was fairly superfluous in my dental routine. I never used it. I didn't suffer from particularly bad breath, and I never understood why so many people felt it was necessary to gurgle and spit blue liquid each morning and night. That is until I started doing some research. Turns out mouthwash can have positive therapeutic and cosmetic effects on your entire mouth, clearing out bad bacteria and offering up healthier gums and teeth in the process. Some even whiten your teeth along with your toothpaste. So I realized I was more down for mouthwash than I'd previously suspected, and I wanted to find the right one for me.
In doing my internet sleuthing, I learned another big thing in regard to mouthwash: They're not all created equal. Turns out alcohol-free mouthwash is far superior to its booze-laden counterpart. Below, find all the reasons to switch to an alcohol-free option, the differences in how they react with your mouth's bacteria, and 10 of my favorite options.
The benefits of alcohol-free mouthwash
According to Colgate's site, most marketed mouth rinses contain an alcohol, specifically ethanol. Ethanol can cause burning and dryness and aggravate many oral conditions as well as Sjögren's syndrome, diabetes, or alcoholism. Beyond that, studies by BioMed Research International suggest alcohol-free mouthwashes have a better effect on the gloss, color, hardness, and wear of your teeth and fillings.
Now, these alcohol-free options still prevent tooth decay, gum diseases, dry mouth, bad breath, and plaque and tartar buildup, as well as work to whiten your teeth. Though, they're gentler and contain natural and often organic ingredients. In fact, when there's no alcohol in the formula, mouthwash can offer anti-inflammatory and anti-fungal therapeutic effects as well.
According to Alliance Dental, alcohol in your mouthwash does destroy almost all the bacteria in your mouth, but it's both the bad and good bacteria, which, if you're using the product every day, means bad breath can actually build up as a result of the imbalance of bacteria. Though alcohol-free mouthwash does not completely wipe your mouth clean, it does target more bad bacteria than good, which creates more of a balance in your mouth and leads to healthier teeth and gums.
