  • Add all of the ingredients to a storage bottle and mix thoroughly.
  • Shake before each use to help disperse the oils and any baking soda or traces of salt that may have settled to the bottom of the bottle.



Use this mouthwash after brushing your teeth or between brushings to leave your mouth feeling refreshed. It can also be used as a gargle for a sore throat.
Take care when using essential oils with children. If they will likely swallow the mouthwash, rather than spit it out, it's probably best to leave out the essential oils or have them avoid using a mouthwash altogether. 
While the salt and the alkalinity of the baking soda help preserve the mouthwash, it's best to make small batches more frequently rather than keeping a large batch for a longer period of time. 
The American Dental Association does not recommend using a mouthwash in children under 6 because they have not fully developed their swallowing reflex yet and may swallow large amounts. While their main concern was the alcohol content of many types of mouthwash, it's something to consider.
To use, pour a small amount into a glass. (15ml or 0.5 ounces is a good estimate of how much to use.) Swish the mouthwash in your mouth for around half a minute. Finish by gargling the mouthwash to help clean the back of the tongue and throat.
Mouthwash can be used before or after brushing your teeth. It can also be used between brushings, when you can't conveniently brush your teeth throughout the day.
