Yes, as long as you’re not swallowing your mouthwash (which you shouldn’t be doing with or without essential oils!).
A review published in the March 2008 issue of Evidence-Based Dentistry found that mouth rinses containing essential oils, combined with standard home dental care, helped reduce plaque and gingivitis, which is the inflammation of the gums.
However, it’s important to note that not all essential oils are made of the same quality. This is because essential oils are an unregulated industry.
While many excellent essential oil producers are putting out safe products, it’s crucial to source quality oils from vendors and representatives you trust.
Always use therapeutic-grade essential oils.
Consult with your dentist to find brands that are safe to use.
