What Are Mouth Ulcers?

Mouth ulcers are cuts/lesions that are formed in the mouth (the gums, the tongue or the insides of the cheeks). They are also called canker sores and can develop due to mouth injuries caused while brushing or during dental treatments. In some instances, these are due to vitamin deficiencies and viral infections.

Types of Mouth Ulcers

Children could get any of the following three types of mouth ulcers. They are categorised depending on their appearance and the time they take to heal. Read on to know more.

• Minor Mouth Ulcers – Minor mouth ulcers are small in size, and they appear round or oval. They are called minor because they heal in one or two weeks and leave minimal or no scarring.
• Major Mouth Ulcers – Major mouth ulcers appear bigger than the minor ones, have deeper sores and irregular edges. These ulcers take many weeks to heal completely and have a tendency to leave scarring because they run deep.
• Herpetiform Ulcers – Its a sub-type of aphthous ulcers and as the name suggests they resemble the ulcers caused due to herpes, but they are non-contagious. Although most cases of mouth ulcers do not require medical attention, there are some, which may cause immense discomfort and would need a diagnosis. You must then take your little one to a paediatrician for immediate treatment or just to rule out serious complications. Now, let’s take a look at the causes of mouth ulcers in children.

Causes of Mouth Ulcers in Children

The most common cause of mouth ulcers in children is injury. However, there are cases wherein children have developed mouth ulcers since it runs in the family. Here are some reasons that can cause mouth ulcers in infants and children:

• Ulcers can be caused due to deficiency of vitamins in children.
• Allergy from food or other irritants can lead to ulcer formation.
• Mouth ulcers can be triggered by minor injuries in the mouth. Biting yourself or using a hard toothbrush can cause mouth injuries which may lead to ulcers.
• The problem can be genetical too.
• Ulcers can also occur due to viral infections.

When children are too young to explain what the discomfort is, parents may not be able to figure out what’s happening to them. For that, you must know the signs and symptoms of mouth ulcers to treat the issue as soon as it is detected.

Signs and Symptoms of Mouth Ulcers in Children

It is easy to identify a mouth ulcer due to its distinguished appearance in the mouth. Following are the signs and symptoms of mouth ulcers in babies and kids:

• An ulcer appears round with a white or yellowish sore centre with a red halo.
• Continuous burning sensation at the affected area inside the mouth.
• Pain or burning sensation experienced by the kid while brushing or chewing can be an indication of a mouth ulcer.
• Tenderness and swollen skin around the sores is a symptom of ulcers.
• The ulcers can bleed while brushing or eating food. Canker sores which are caused by a viral infection can also be accompanied by fever.

At times, children might get a cold sore which might be confused with a mouth ulcer. Here’s how cold sores are different than mouth ulcers/ canker sores.

Difference Between Canker Sore and Cold Sore

Canker sores are completely different from a cold sore. Canker sores appear in the soft tissues of the mouth and are not contagious. Cold sores, also known as fever blisters, are caused by herpes simplex virus and are contagious. Cold sores generally appear on the outside of the lips.

It is better to avoid hot, spicy or citrus food as they will make the ulcers hurt even more. The paediatrician may suggest applying teething gel or cream on the affected area.

In case of severe pains in the sores, you can request your doctor to give a proper dose of over the counter pain relievers such as acetaminophen or ibuprofen. It is advised not the give any kind of medication to your child without first consulting the doctor.
