Listermint and Oral-B both make moutwashes that are alcohol-free. There's always the tried-and-true baking soda, which is alcohol free, that is great for oral hygiene. If you use mouthwash to prevent bad breath, anything with peppermint, spearmint, or almond have been known to help. Overall, mouthwash isn't really necessary for oral hygiene, brushing and flossing will do the trick.
