How to treat a canker sore with essential oils?
Whatever the origin of the canker sore, its discomfort is such that we often want to get rid of it immediately! How to get a healthy mouth quickly? What if essential oils were the solution? 100% natural, their properties act immediately so that you find a perfect mouth.

Why use essential oils against canker sores?
Our oral mucosa is very sensitive and small superficial ulcerations may appear. This is called canker sores. Often painful, they are inhibited thanks to the analgesic, analgesic and anesthetic properties of essential oils. Associated with anti-inflammatory, healing and immune-stimulating benefits, essential oils activate healing so that this discomfort is quickly forgotten.
