What the experts say

Experts continue to debate questions about the effectiveness of mouthwash use in boosting oral health. Organizations such as the American Dental Association (ADA) and the Academy of General Dentistry (AGD) agree that the benefits of mouthwash depend on the type of rinse that is used.

For example, both the ADA and AGD agree that mouthwashes that contain fluoride may reduce bacteria that cause cavities. These organizations also state that using a cosmetic mouthwash can freshen breath for several hours.

However, studies have shown that rinsing with water is nearly as effective in reducing plaque and the risk of periodontal disease as using anti-plaque and anti-gingivitis rinses, according to the AGD. In addition, the ADA emphasizes that cosmetic mouthwash only masks bad breath for a few hours (rather than eliminating it). The AGD does not specifically advocate using mouthwash as part of its suggested routine for maintaining good oral hygiene.

Despite such statements, many individual dentists recommend that their patients use mouthwash on a regular basis. These dentists maintain that using mouthwash, along with flossing and brushing, may further improve the health of your teeth and gums.

Using your rinse safely

If you do use mouthwash, there are several factors to keep in mind. Many over-the-counter mouthwashes contain levels of alcohol ranging from 18 percent to 26 percent, which is a higher percentage than found in some alcoholic drinks. If you use too much of this type of solution, you may develop an unpleasant burning sensation in your cheeks, teeth and gums.
