Which Mouth Rinse Should I Use?

When you go to the store there are rows and rows of rinses for your mouth.  Which one do you choose?  Rinses are generally classified by the U.S. Food and Drug Administration as either cosmetic, therapeutic, or a combination of the two.  Cosmetic rinses are commercial over-the-counter products that help remove oral debris before or after brushing, temporarily suppress bad breath, diminish bacteria in the mouth and refresh the mouth with a pleasant taste.  Prescription, therapeutic rinses are regulated by the FDA and have the benefits of their cosmetic counterparts, but also contain an added active ingredient that helps protect against some oral diseases.  They can be categorized into types according to use: antiplaque/ antigingivitis rinses and anticavity fluoride rinses.

Should I use a rinse?
That depends upon your needs.  Most rinses are, at the very least, effective oral antiseptics that freshen the mouth and curb bad breath for up to three hours.  Their success in preventing tooth decay, gingivitis and periodontal disease is limited, however.  Rinses are not considered substitutes for regular dental examinations and proper home care.

Which type should I use?
Again, that depends upon your needs.  While further testing is needed, initial studies have shown that most over-the-counter antiplaque rinses and antiseptics aren't much more effective against plaque and periodontal disease than rinsing with plain water.  Many dentists are skeptical about the value of these antiplaque products, and studies point to only a 20 to 25 percent effectiveness, at best, in reducing the plaque that causes gingivitis.

When a patient is healthy, most dentists consider the use of fluoride toothpaste and flossing to be more than adequate protection against cavities.  Dentists will prescribe certain rinses for patients with more severe oral problems such as decay, periodontal disease, gum inflammation and xerostomia (dry mouth).  Therapeutic rinses are strongly recommended for those who can't brush due to physical impairments or medical reasons.

What is the proper way to rinse?
First, take the proper amount of liquid as specified on the container or as instructed by your dentist into your mouth.  Next, with the lips closed and the teeth slightly apart, swish the liquid around with as much force as possible using the tongue, lips, and sucking action of the cheeks.  Be sure to swish the front and sides of the mouth equally.  Most rinses suggest swishing for 30 seconds to a minute.  Time it –it’s longer than you think!

Are there any side effects to rinsing?
Yes, and they vary depending on the type of rinse.  Habitual use of antiseptic mouthwashes containing high levels of alcohol (ranging from 18 to 26 percent) may produce a burning sensation in the cheeks, teeth and gums.  Some prescribed rinses with more concentrated formulas can lead to ulcers, root sensitivity, stains, soreness, numbness or temporary changes in taste sensation.  If you experience any irritating or adverse reactions to a mouth rinse, discontinue its use immediately and consult your dentist. 

There are so many to choose from and I know it can be confusing.  Although most rinses won’t do any harm when used properly, always consult your dentist – He/she could keep you from spending money you don’t need to spend!
