5 Essential Oils to Kill Mouth Bacteria

Check out these five essential oils that have been shown to decrease oral bacteria and tooth decay.



This oil has been used in dentistry for a while. Many dentists use it during root canals or to treat dry sockets. Clove has powerful antifungal and antibacterial properties that are important for preventing infections in both scenarios. It can also help you prevent tooth decay by keeping harmful bacteria at bay.


Cinnamon oil is a great antibacterial agent against Streptococcus mutans, the nasty bug that causes most tooth decay. But you have to be careful. Cinnamon can be an irritant to the tissue in the mouths of some individuals. So always test a small area  first before diving in all the way.


Peppermint Oil:

Peppermint offers the benefit of taste and increased salivation. Extra saliva in the mouth can be helpful for those who deal with bad breath caused by dry mouth. In addition, regular saliva production helps your teeth to remineralize naturally.


If you’re dealing with gum disease, mouth ulcers or other wounds in your mouth, then is the essential oil for you. One study noted that myrrh had the ability to repair mucosal wounds when used as a rinse over a two week period. If used longer, it can cause damage. Be curious but cautious. If you have myrrh on hand, it could help to expedite the healing of your mouth sores.

Tea Tree

Tea tree oil has a significant impact on the formation of biofilm on your teeth. Biofilm is created by bacteria that allows them to adhere more snuggly to teeth, making it more difficult to remove the bacteria. Add tea tree oil to your oral care routine and rid yourself of that nasty biofilm.


The Basic Recipe…

4 Tablespoons Bentonite Clay
3 Tablespoons Calcium Powder
1 Tablespoon baking soda

Now Add Essential Oils (or powders)…

1 and ½ teaspoons ground Peppermint leaves (or 5-10 drops essential oil)
1 Tablespoon Cinnamon powder (or 5-10 drops essential oil)
1 teaspoon to tablespoon Clove powder (or 5-10 drops essential oil)

You can add activated charcoal to help with teeth whitening, or xylitol or stevia for a hint of sweetness.
