5 Best Essential Oils For Canker Sores

Did you ever have lesions inside your cheeks or lips, at the base of your gums, or under your tongue? These are canker sores. You’ll know you have one if it becomes hard to speak, drink or eat. Luckily, there are natural remedies available, like essential oils for canker sores.

An In-Depth Look at Canker Sores

Canker sores, otherwise known as mouth ulcers, are small, oval-shaped, shallow lesions. They grow on the soft tissues inside your mouth. Before they appear, you may see some redness and feel a stinging sensation.

Most people will have them at least once in their lifetime. The sores disappear on their own after one or two weeks. Severe cases of canker sores, which are agonizing and take longer to heal, are less common.

They are not contagious, and different from the cold sores, caused by the herpes virus. The main distinction is that cold sores appear on the outside of your mouth and lips. Here’s a video explaining their differences in detail.

Why Use Essential Oils for Canker Sores?

Drug-resistant viruses and bacteria have surfaced in recent years. That’s why scientists are continually searching for other ways to fight them.

Essential oils are getting noticed for their healing properties. Essential oils have been used in natural medicine for many centuries. They come from plant material such as leaves, flowers, roots, seeds, bark, and fruits.

One study shows that peppermint, thyme, and tea tree oil can fight bad bacteria inside the mouth.
