Mouth Sore Relief for Children

For minor mouth sores, encourage your child to avoid spicy, salty, acidic, or very hot foods that can irritate the sore. Cool drinks and soft foods may be more comfortable.

Older children who can safely rinse and spit may also benefit from a saltwater rinse or an oral rinse intended for their age group.

Some over-the-counter oral pain-relief products contain benzocaine. These products can temporarily numb a painful area, but age restrictions vary. Always check the Drug Facts label before giving an oral pain-relief product to a child.

The FDA warns that benzocaine should not be used in children younger than 2 years because it can cause a rare but serious blood disorder called methemoglobinemia.

For children age 2 and older, follow the age restrictions and directions on the individual product label. Some manufacturers recommend speaking with a doctor or dentist before using benzocaine products in younger children.

Benzocaine should never be used to treat teething pain.

Talk with your child's doctor or dentist if a mouth sore is unusually large or painful, keeps returning, does not heal, or makes it difficult for your child to eat or drink.

You should also seek medical advice if mouth sores occur with fever, significant swelling, a widespread rash, dehydration, or other signs of illness.

Seek emergency medical help if your child develops difficulty breathing, swelling of the mouth or tongue, blue or gray lips or skin, unusual weakness, confusion, or other signs of a serious reaction.
