Common causes of mouth ulcers in young children include herpetic gingivostomatitis, hand-foot-mouth disease, herpetic angina, gingivitis, and tongue coating.

recurrent mouth ulcers

Recurrent ulcers can be difficult to diagnose because there are many possible causes. Some are as simple as oral trauma caused by dental appliances or habitual cheek biting. It may happen again until the underlying problem is resolved.

By far the most common relapse is aphthous stomatitis (also called mouth ulcers). Food allergies and vitamin deficiencies are thought to increase the risk of mouth ulcers in children. In many cases, the reason cannot be found.

Another possible cause is herpes simplex virus 1 (HSV-1), the virus associated with cold sores. While most people develop cold sores on the lips, others may develop cold sores inside the lip. Relapses are common, with some people having five or six outbreaks a year.

Recurrent mouth ulcers can also be the result of systemic (systemic) disorders such as:

  • Behcet syndrome: a rare autoimmune disorder that causes recurrent mouth ulcers, genital ulcers, and eye damage
  • Celiac disease (CD): An autoimmune disease that affects the small intestine and is caused by eating gluten, a grain protein found in wheat, rye, and barley
  • Cyclic neutropenia: a recurring drop in a type of white blood cell called a white blood cell neutrophils Can cause mouth sores and fever
  • HIV: a sexually transmitted infection that destroys the immune system
  • Inflammatory bowel disease (IBD): a group of diseases that cause chronic inflammation of the digestive tract
  • Periodic Fever Syndrome (PFAPA): Children experience fever, mouth sores, and sore throat every two to eight weeks.
  • Vitamin deficiencies: including iron, folic acid, zinc and vitamin B12 deficiencies


The most common causes of recurrent canker sores in children include mouth sores (mouth sores) and herpes simplex virus 1 (cold sores).


Treatment of mouth ulcers focuses on relieving symptoms. This includes over-the-counter pain relievers using Tylenol (acetaminophen) or nonsteroidal anti-inflammatory drugs (NSAIDs) such as Advil (ibuprofen).

There are also medications that cover the ulcer and relieve pain. These include toothpaste and liquid antacids such as Maalox or milk of magnesia.

Local anesthetics can help numb the pain in the mouth. These include 2% viscous lidocaine and benzocaine formulations such as Anbesol or Orajel Mouth-Aid.

Antiseptics such as Peridex (chlorhexidine gluconate) and Cepacol (hexadecylpiperidine chloride) can also provide pain relief when used as a mouthwash twice a day.

Prescription steroids are also sometimes used. This includes Kenalog-40 (0.1% triamcinolone acetonide), a steroid drug that can be mixed with toothpaste and applied to the ulcer several times a day.


Treatment of mouth ulcers may involve over-the-counter pain relievers, coatings, topical anesthetics, antiseptic mouthwashes, and prescription topical steroids.


If your child has recurring mouth sores, it is often helpful to keep a symptom log. This allows you to determine what might have caused the outbreak. By identifying possible triggers, you can avoid foods or substances that put your child at risk.

If no triggers are found, toothpaste or mouthwash containing triclosan may help. Triclosan has antibacterial properties that may reduce the risk of relapse in some children. Colgate Total toothpaste contains triclosan.

On the other hand, an additive called sodium lauryl sulfate (SLS) used in many toothpastes and mouthwashes may trigger aphthous stomatitis in some people. If your child is prone to recurrent canker sores, choose an SLS-free toothpaste, such as Biotene and Rembrandt’s canker sore toothpaste.

Dry mouth also increases the risk of mouth ulcers. You can reduce the risk by making sure your child drinks water regularly. You can also have them chew sugar-free gum when they have a dry mouth.

Older children often have recurrent mouth sores, most often caused by aphthous stomatitis (mouth sores) or herpes simplex virus 1 (cold sores).

Certain systemic diseases can also cause repeated mouth sores in children. These include celiac disease, inflammatory bowel disease, vitamin deficiency, and periodic fever syndrome.

Mouth ulcers can be treated with over-the-counter pain relievers, coatings, topical anesthetics, antiseptic mouthwashes, and prescription topical steroids.
