A Natural Remedy: Using Aloe Vera Gel To Mouth Ulcers

If you’ve ever experienced the discomfort of a canker sore, you know that it can be annoying. Although they are usually harmless, the truth is, that they can complicate things as simple as eating a taco or singing “Happy Birthday.” Is there a natural and effective way to treat them? Of course! Aloe vera, that humble green gel, can be your new best friend in such cases.

What are Mouth Ulcers?

Mouth ulcers, or canker sores, are small sores that appear in the mouth, usually on the inside of the lips, cheeks, tongue, and gums. They can be described as small whitish areas surrounded by a reddish halo and are usually quite painful on contact. Some people also report burning and itching in the affected area.

Common causes

The triggers for mouth ulcers can be varied: from an injury to the mouth or stress, to nutritional deficiencies, autoimmune disorders, or effects of cancer treatments. Mouth ulcers are not contagious, but they can recur, especially if the underlying cause is not adequately addressed.

Aloe Vera Gel as a Natural Remedy

Why Aloe Vera?

Since ancient Egypt, aloe vera has been praised for its many medicinal uses. But what makes it so good for treating mouth ulcers? Simple: it has anti-inflammatory, antioxidant, and healing properties that make it an effective remedy.

Chemical Composition of Aloe Vera Gel

Aloe vera is a succulent plant that stores in its leaves a gel rich in water, enzymes, vitamins, and other bioactive compounds. Among these, acemannan stands out for its ability to accelerate healing and reduce inflammation.

Benefits of Aloe Vera for Mouth Ulcers

1. Anti-inflammatory Effects

Aloe vera contains several compounds that reduce inflammation, such as saponins. This is especially useful in the case of mouth ulcers, where inflammation can be the main cause of pain (Pandey & Cabot, 2015. Source).

2. Promotion of Healing

Another wonder of aloe vera is its ability to accelerate healing. In studies, aloe gel has been shown to promote collagen synthesis, thus helping wounds close more quickly (Thunyakitpisal et al., 2012. Source).

What does Science Say?

Numerous studies have explored how aloe vera helps heal mouth ulcers. Researchers have even compared it to the use of over-the-counter medications. A study published by Doctor Sahebjamee and collaborators in 2015 showed that aloe vera is as effective as benzydamine for the treatment of mouth ulcers generated by radiotherapy, in addition to being cheaper, having a more pleasant flavor, and having fewer side effects. For these reasons, many dentists and oral health experts recommend using aloe vera to treat mouth ulcers.

Guide to Applying Aloe Vera Gel


Before applying aloe vera to your mouth, make sure it is free of additives and fragrances, as these can further irritate the ulcer. Also, if you are pregnant, nursing, or have any medical condition, consult your doctor before use.

Steps to Follow

1. Wash your hands and mouth.

2. Apply a small amount of the gel directly to the ulcer.

3. Massage the area for a minute.

4. Leave on for a few minutes before rinsing or swallowing.

5. Repeat this several times a day until you achieve improvement.

Common Mistakes When Treating Mouth Ulcers

One of the most common mistakes is scratching or picking at the ulcer, which can make the situation worse. You should also avoid using mouthwashes that contain alcohol, as these can irritate the ulcer further.
