Commercial dental hygiene products are packaged in single-use plastic, and often contain ingredients you don’t really want or need. With these DIY mouthwash recipes, you can keep your mouth feeling fresh naturally.

But using an all-natural DIY mouthwash is still a great way to give your oral hygiene a mini-boost and to keep your breath fresh. Plus, it lets you skip the plastic packaging and suspicious chemicals.
