Most mouth rinses are effective oral antiseptics that freshen the mouth and curb bad breath for up to three hours. Their effectiveness in preventing tooth decay, gingivitis and periodontal disease is limited, however. Here is the recommended regimen for good oral hygiene:

• Brush your teeth twice a day with fluoride toothpaste. Make sure to brush for at least three minutes; it takes several minutes of brushing to do a thorough job.
• Use floss or an interdental cleaner daily.
• Eat a balanced diet and limit sugary or carbohydrate-loaded snacks.
• Look for the American Dental Association (ADA) Seal on fluoride toothpaste, toothbrushes, floss, interdental cleaners, oral irrigators, mouth rinses and other oral hygiene products. The ADA Seal on a product is your assurance that it has met ADA criteria for safety and effectiveness.
• Use a toothbrush with soft bristles. Toothbrushes with medium or hard bristles actually can wear away tooth structure over time.
• Replace your toothbrush at least every four months, sooner if the bristles become frayed. (Children’s toothbrushes often need replacing more frequently than adults’ because they can wear out sooner.)
• Visit your dentist regularly for professional cleanings and oral exams.
