Breath fresheners are products designed to improve oral freshness and reduce bad breath. They come in various forms, including mints, gums, sprays, and lozenges. Many contain ingredients like xylitol, menthol, or essential oils that help mask odors and promote a clean feeling in the mouth. These products often target bacteria that cause bad breath, providing a quick solution for freshening up. While they can be effective for temporary relief, maintaining good oral hygiene through regular brushing, flossing, and dental check-ups is essential for long-term breath freshness.
