mouthrinses

Mouthrinses, also known as mouthwashes, are liquid oral care products used to rinse the mouth. They are designed to reduce oral bacteria, freshen breath, and support oral health. They range from cosmetic rinses that mask odor to therapeutic rinses that provide clinical benefits when used with brushing and flossing.

Therapeutic rinses contain active ingredients such as fluoride for caries prevention; antiseptics like chlorhexidine, cetylpyridinium chloride (CPC), or essential oils; peroxide-based agents; or desensitizing agents. Fluoride rinses help reduce cavities; chlorhexidine can reduce plaque and gingivitis but is typically used for limited periods due to staining and taste changes. Alcohol-containing rinses may improve mouthfeel and antimicrobial activity, but can cause dryness; alcohol-free versions are available.

Use and guidance: rinse typically for 30 to 60 seconds and then spit out; do not swallow. Do not eat or drink for about 30 minutes after use unless advised. Use as directed by product label or a clinician. Children may require supervision or age-appropriate formulations. Some rinses are prescribed for specific conditions or post-procedure care.

Safety and limitations: mouthrinses supplement but do not replace brushing and flossing. Potential side effects include tooth staining (especially with chlorhexidine), taste alteration, mucosal irritation, and dry mouth. Some products interact with dental restorations or medications. Look for products with evidence-based claims or professional oversight, and be aware of alcohol content; consult a clinician if pregnant, nursing, or taking medications.
