Viral gingivostomatitis (mouth sores, sore gums)
The herpes simplex virus causes blisters or "cold sores" on your child's lips and mouth (viral gingivostomatitis). Anyone at any age can get herpes.
If your child has lots of mouth sores, eating and drinking may be difficult or painful. You need to make sure your child gets plenty of fluids to prevent dehydration (loss of fluids and minerals).
Symptoms of herpes simplex are:
- lots of sores or ulcers over the lip, in the mouth or on the tongue
- swollen gums that can bleed
- swollen neck glands.
Your child can spread this virus by mouth contact of any kind and skin-to-skin contact with an open sore on an infected person.
How to make your child more comfortable
- Give your child extra liquids. Avoid acidic juices such as orange juice.
- Give your child soft foods like soups, custard, Popsicles, ice cream, pudding and yogurt.
- You may try an over-the-counter medicines like Chloraseptic® mouth rinse or gel to relieve discomfort.
- Give your child acetaminophen (Tylenol®) to reduce fever. Follow package directions for your child's height, weight and age.

Call your health care provider for an appointment if your child has any signs of dehydration:
- dry mouth
