Essential Oil Saltwater Mouthwash

Saltwater makes a great mouthwash because the it alkalizes the mouth, creating an environment that stops the growth of bacteria. Additionally, saltwater is astringent and speeds wound healing by reducing inflammation and contracting the tissues. We included essential oils in our saltwater mouthwash because their antibacterial properties kill the existing bacteria and help freshen the breath.

Some good oils to use in a mouthwash include peppermint, melaleuca, orange, cinnamon, clove, lemon, myrrh, or an antibacterial blend. Try using a single oil or mixing a couple to create your own custom blend! Though you don’t often see myrrh used in mouthwash, myrrh essential oil is actually a great oil to use in oral care because it is said to help with sore throats, mouth ulcers, gingivitis, gum disease, and wounds.

This mouthwash is great to use on a daily basis or even just when your mouth needs a little help healing from mouth wounds or conditions.
