How to Make Homemade Mouthwash Recipe

Pick a Mouthwash Base

The first thing you need to make a natural mouthwash is the right base for your wash.

You have several choices with this. You can use a bacterial killing cane alcohol or pure alcohol base such as vodka. Dilute this down with water.

Most people use filtered water for this as a base. Water works well without the burn and is ideal if you have issues with alcohol.

Add Remedies to Your DIY Mouthwash

Salt and baking soda are common mouthwash additives, and just what we need for this baking soda mouthwash recipe.

Salt has been used since ancient times for its medicinal properties and is perfect for soothing and healing inflammation in the mouth.

Baking soda can help neutralize the PH in your mouth which will reduce tooth enamel decay. It’s also a good home remedy for canker sores in the mouth.

Salt and baking soda make a healthy combo for a homemade mouthwash.

In addition, essential oils can be added for antibacterial properties as well as a punch of freshness.

Research which essential oils or herbs to add to the mouthwash and add those accordingly. You may have a particular need for your mouthwash that isn’t common.

Common essential oils for mouthwash are cloves for pain and inflammation or peppermint for antibacterial and fresh breath.

Make sure it’s a pure clean essential oil and not fragrance oil. There is a huge difference in use and quality.

We love Eden’s Garden’s Essential Oils! Perfect quality without the MLM prices.

Store Your Baking Soda Mouthwash Correctly

One of the issues many people have with a natural mouthwash gone bad is the way it was stored. Make sure you are storing it in a cool dry place.

Remember, a natural mouthwash does not have the preservatives and other chemicals that keep store purchased options fresh.

You need to store the mouthwash in a glass bottle or jar. This will keep plastics from leeching into the mouthwash causing other issues as well. Remember to give it a good shake before using it.
