Mouth rinses may leave your breath feeling fresh. But some mouth rinse formulas may actually be doing your mouth more harm than good. Mouth rinses do provide a fresh, crisp feeling after use. And many help to prevent cavities and plaque buildup. But, for some people, mouth rinses can be harmful. They may actually be covering up the symptoms of an oral health disease or condition. With some conditions such as periodontal disease, bad breath (halitosis) and an unpleasant taste in your mouth are the first (and sometimes only) signs that something is wrong.
The U.S. Food and Drug Administration (FDA) classifies mouth rinses as either cosmetic or therapeutic, or a combination of the two.

It is important to note that most dentists are skeptical about the value of these anti-plaque, mouth-rinsing products. Several studies have shown the products' minimal effectiveness in reducing plaque. Use these products with caution, under the direction of an oral healthcare specialist.

Rinses of any kind should not be a substitute for regular dental exams and correct home care.
The ingredients of mouth washes vary. But some contain high levels of alcohol--ranging from 18% to 26%. This may cause a burning sensation in the cheeks, tongue, and gums. Or may cause intoxication if swallowed or used excessively. For children, even small doses of these over-the-counter rinses can potentially be lethal. Mouthwash with alcohol has not been directly linked to oral cancer. But alcohol is the most important risk factor for oral cancer in nonsmokers.
