The Complete Guide to Mouth ulcers: Recommended Drugs and How to Choose

Mouth ulcers can be caused by a variety of factors, including stress, nutritional deficiencies such as vitamins, brushing teeth too hard, biting, and medication.

If they are mild, they can be left alone and usually heal within a week or so, but because they are painful, many people want to get rid of them as soon as possible.

This article summarizes what a mouth ulcer is, how to treat it at home, and what medications are available over the counter.


What are mouth ulcers?

Stomatitis is an inflammatory disease of the oral mucosa.

They occur mainly on the tongue, inner cheeks, and lips, and are painful.

It often causes discomfort in daily living, eating, and speaking, and contributes to a decreased quality of life.

Symptoms and Causes of Mouth ulcers

The main symptom of stomatitis is the formation of small ulcers in the mouth and inflammation around them.

It is painful and can make eating and speaking difficult.

There are three main types of causes of stomatitis: aphthous stomatitis, catarrhal stomatitis, and viral stomatitis.

Aphthous stomatitis: often caused by stress, poor nutrition, or fatigue

Catarrhal stomatitis: caused by oral contamination or mechanical irritation (e.g., accidental biting)

Viral stomatitis: caused by viral infections, often herpes viruses are a contributing factor


The over-the-counter medications discussed primarily in this article are used for aphthous and catarrhal stomatitis

How long does it take for mouth ulcers to heal?

Recovery time for mouth ulcers depends on their cause and treatment.

Generally, with the proper over-the-counter medications, the disease will heal in one week to 10 days.

However, if your mouth ulcers do not heal for more than two weeks or if the symptoms worsen, we recommend that you consult a medical specialist or pharmacist.

A medical examination at a medical institution will help you receive more appropriate treatment.

Pharmacist’s Recommendations for Over-the-Counter Medicines

The key to quickly relieving the pain and discomfort of mouth ulcers is to make good use of over-the-counter medications.

The following are pharmacists’ recommendations for over-the-counter medications based on the ingredients of the drugs!

The basics of mouth ulcer treatment are the steroid “Triamcinolone” or the anti-inflammatory drug “Azulene.”

Although there is no data to indicate which is better than the other, it is recommended to choose “Triamcinolone” for severe symptoms and “Azulene” as the main ingredient for mild symptoms.
