It’s important to keep in mind that many off-the-shelf mouthrinses are primarily cosmetic: That means, they may (temporarily) make your mouth taste or smell good, but they don’t offer any lasting benefit to your oral health. There’s nothing wrong with that — as long as you weren’t expecting anything more. But if you’ve been told that you are at risk for tooth decay or gum disease, you’ll want to use a mouthrinse that has proven clinical benefits.
To help prevent tooth decay, anti-cariogenic mouthrinses use an ingredient you’re probably already familiar with: fluoride. This is often in the form of a .05% sodium fluoride solution. Because it’s a liquid, the rinse can get all around your teeth — even into spaces the smallest brush can’t reach.
Fluoride has been consistently proven to strengthen tooth enamel, which protects against decay; it can even reduce tiny lesions on teeth where a cavity may form. There’s hardly anyone who couldn’t use some extra help in the fight against cavities — but if you’ve been told you may be at a higher risk for tooth decay, or if you have difficulty brushing and flossing, then an anti-cariogenic rinse is a good choice for you.
Anti-bacterial mouthrinses generally contain ingredients (like triclosan, essential oils, or the prescription medication chlorhexidine) that help to control the microorganisms found in plaque. Plaque, a sticky, bacteria-laden biofilm, occurs not only on the surfaces of the teeth, but also in other parts of the mouth. Rinsing with an anti-bacterial solution has been shown to provide a greater reduction in plaque than brushing and flossing alone. As tools in the fight against gum disease (gingivitis) and tooth decay, anti-bacterial mouthrinses may be a good step toward improving your oral hygiene.
