What to do If Your Baby Has a Mouth Ulcer

Mouth ulcers are painful sores that appear in the mouth. They are common in adults, children and babies with between 5%-10% of children and infants being affected. Although they are not unusual they can be distressing for both parents and child due to the pain and discomfort they cause.


What are the signs of a mouth ulcer? 

Mouth ulcers usually appear on the inside of the cheeks and lips, on the floor of the mouth and on the under the surface of the tongue. It is rare for them to appear on the roof of the mouth. They are mostly round or oval in shape, white, red, yellow or grey in colour and swollen around the edge. Mouth ulcers are often painful so your baby may be irritable and distressed.


What causes a mouth ulcer in babies?  

There are a number of reasons why an infant may have a mouth ulcer. They often occur during and after teething as the baby may bite the side of their cheek. Damage to the mouth can also occur by chewing something rough or catching their cheek or lip on a sharp tooth or filling. Mouth ulcers can also occur in babies who are tired and run down.

In some cases, a mouth ulcer may be a sign of a lack of vitamins or an infection.
