mouthwash needs are for basic breath freshening, you can read reviews and ask friends which products they like. Mouthwashes and rinses are available in different flavors such as mint and cinnamon, and you can keep more than one type on hand for variety. If you aren't sure whether you'd like the taste or sensation of a mouthwash, ask your dentist about getting a free mouthwash sample that you can try. Also, if you want a mouthrinse to prevent cavities or kill germs and control plaque, ask a dental professional.
