Using Liquid Castile Soap to Brush Your Teeth

Have you ever considered using liquid castile soap to brush your teeth?!

Our latest use for liquid castile soap may be a bit lesser known than using it to wash your dishes or to clean your laundry. It might even be more surprising than when we told you how to use liquid castile soap as produce wash and pet shampoo. However, this is actually one of our absolute favorite uses from the whole list.

You may not have guessed it, but you can even use liquid castile soap to brush your teeth! 

Most of us don’t usually think of using soap when we think of brushing our teeth. But did you know that many commercial kinds of toothpaste contain abrasive ingredients that may be irritating to the gums and soft mouth tissues of some users? Some commercial toothpaste even contains ingredients that may weaken your enamel and increase tooth pain and sensitivity over time.

As we previously mentioned in our post about using liquid castile soap as body wash, we know that castile soap is a gentle cleanser that is made from all-natural oils and is free from synthetic detergents, dyes, fragrances, and preservatives. These are the ingredients most likely to irritate sensitive tissues like those in your mouth. But because liquid castile soap does not contain these ingredients, that means that it is not only completely safe and effective to use to brush your teeth, but that it can even become your permanent replacement for toothpaste!

Whether you want to ditch the ‘paste completely, or if you just want to know how to substitute liquid castile soap for toothpaste in a pinch, keep reading to learn our tips for brushing your teeth with liquid castile soap.

Using Liquid Castile Soap to Brush Your Teeth

Preparation: Gather Your Materials

• There is no need to dilute your liquid castile soap in advance. However, we do find it to be convenient to keep a small bottle of full-strength liquid castile soap nearby our toothbrushes. Travel- or toiletry-sized bottles work well.

Note: Remember to choose a container with a squeeze- or pour-style dispenser, because pressurized pump-style dispensers are not safe to use with full-strength liquid castile soap.

Bonus Tip!: Designating a smaller bottle of liquid castile soap for this purpose is not only more convenient than dispensing from a large bottle, but it also means that each family member can choose a specific scent/flavor that they prefer for brushing their teeth.

We especially enjoy brushing our teeth with our Eucalyptus & Peppermint liquid castile soap, but Unscented liquid castile soap is always a safe option for the whole family and can be customized with food-safe essential oils (see instructions below).

Step 1:

Wet your toothbrush with a small amount of water.

Step 2:

Add a drop or two of liquid castile soap to your toothbrush.

Note: Remember that full-strength liquid castile soap is highly concentrated, so make sure not to use more than a couple of drops.

Step 3:

Brush your teeth as you normally would.

Note: As you brush, the liquid castile soap will create a sudsy foam. Spit out the excess foam the same as you would if brushing with toothpaste. Try not to swallow the foam.

Step 4:

Don’t forget to brush your tongue, too!!

Step 5:

Rinse thoroughly with fresh water.

Step 6:

Enjoy your clean teeth and naturally-fresh breath!

One of the ways liquid castile soap is different from most commercial liquid soaps is that most commercial liquid soaps have added synthetic bittering agents designed to discourage ingestion. Liquid castile soap contains no synthetic detergents (which are harmful to ingest). Therefore does not require the addition of such bitter deterrent ingredients.

However, liquid castile soap is indeed still soap. We don’t find the flavor of liquid castile soap to be unpleasant, but some people may find it to be too strong and/or too dissimilar to the toothpaste flavor they are most used to.

Of course, we encourage you to stick it out and give your taste buds and brain time to acclimate to the unique experience of brushing your teeth with liquid castile soap. However, you can also dilute the liquid castile soap prior to use to weaken the flavor. If you are starting with unscented liquid castile soap, you can also try adding a couple of drops of a food-safe essential oil of your choice, like peppermint, spearmint, or cinnamon, which should help to make the experience feel more pleasant and familiar.
