The use of essential oils has gained significant interest, with the market expected to reach $12 billion by 2022, calculates Grandview Research.

Because of their aromatic and therapeutic qualities, essential oils are being used in medicine, holistic therapies, cosmetics, and even self-care treatments. But do essential oils work for a dry mouth?

Essential Oils for Treating Dry Mouth

Xerostomia is an oral condition known as dry mouth, where the salivary glands in your mouth don't produce enough saliva to keep your mouth moist. Dry mouth can be a side effect of some medications and treatments like chemotherapy and radiation. It can also be a sign of dehydration. Dry mouth can be uncomfortable and, if left untreated, it can lead to plaque buildup, tooth decay, and gum disease.

Grapeseed oil is often recommended as a treatment for dry mouth. Some people suggest rubbing a small amount inside the mouth to aid with moisture, while others make an oil wash (water and grapeseed oil mix). The mixture is then swirled around the mouth and through the teeth to help with lubrication. Remember to always consult with your dentist before trying any at-home remedies.

How effective Are Essential Oils?

There is ongoing research about the benefits and efficacy of essential oils in oral health. According to an article published by the Journal of International Society of Preventative & Community Dentistry, essential oils like lavender oil, eucalyptus, peppermint, and clove oil may prevent and treat oral disease. This is because of their therapeutic properties. Most essential oils have antibacterial, antifungal, and antioxidant qualities. Although ingredients like eucalyptus and peppermint can be found in oral hygiene products, further research is needed to determine how effective natural oils are in treating oral issues.
