Pain in the Mouth of Children


If a toddler does not want to eat or drink, it may be because it hurts the mouth. Children who are two years or older can often tell themselves that they have mouth pain.

There are several reasons why children get mouth pain. When the first teeth come, it can hurt many in their first years. It is also called tooth cracking. Then the child can drool more than usual and want something to bite into.

But there are also other reasons why a child has mouth pain.

Symptoms of pain in the mouth of children

That it hurts the mouth can be shown by the fact that the child does not want to eat and drool more than usual. Often the child may also have a fever.

When and where should I seek care?

Seek care at BVC, a health care center, or pediatric clinic if the child has severe mouth problems or difficulty drinking because of pain in the mouth.

What can I do myself to help the child?

Difficulties associated with tooth fracture can be alleviated with the help of a bitterness that may be cold. Cooling relieves the pain.

When the baby has blisters and ulcers in the mouth it can be difficult to eat and drink. It is most important that the child can have a drink. You can try any cold drink that your child likes. Ice cream or yogurt can also be good.

To make it easier for the child to drink or eat, you can give painkillers.

  • You can give medicines containing paracetamol to children from three months of age. 
  • You can give medicines containing ibuprofen from the age of six months. Do not give ibuprofen for chickenpox due to the risk of complications.

The drugs are available in several different forms that are suitable for children, such as orodispersible tablets and solutions. Ask a pharmacy what is right for your child.

Follow the instructions on the package carefully and do not combine different medicines. Here you can read about combining paracetamol and ibuprofen. 

You can read more about medicine in the package leaflet that comes with the package. You can also search the drug at and read the package leaflet there.

What is it?

One reason why it hurts your mouth can be a fungal infection called cod. It is usually children who breastfeed or drink from bottles that get cod. A whitish coating forms on the tongue, inside of the cheeks and palate. Cod is harmless and often heals within a few weeks. Not all children get the trouble of cod.

Sometimes the mucous membranes in the mouth turn red during fungal infection. Often it also hurts the mouth.

autumn Blisters

Blisters and ulcers in the mouth usually sit on the inside of the cheeks, tongue, and gums. The mucosa becomes swollen, red, and bleeds easily. The cause may be autumn blisters, which are due to viruses and are most common in children up to the age of ten.


In conjunction with a cold, blisters in the mouth and around the mouth may be due to a  herpes infection. The virus stays in the body even after the symptoms have disappeared and some children can have it several times.


Sometimes chickenpox can cause the child to get mouth pain.


Small gray-white cold sores with a red zone all around can be called after . Often the wound sits on the inside of the lips.

You can seek care at any medical center or open specialist clinic you want throughout the country. Sometimes a referral  to the open specialized care is required.
