Your child may be TEETHING.
Use teething rings or let your baby chew on a wet washcloth. Rub your baby’s gums with a clean finger. Wipe off drool to prevent rashes on the baby’s face. Use children’s acetaminophen to relieve discomfort, but call your doctor if the baby develops a fever.
Your child may have GUM DISEASE, such as GINGIVITIS or PERIODONTITIS, usually caused by poor DENTAL HYGIENE.
Take your child to the dentist. Good dental hygiene such as regular brushing, flossing, dental checkups and eating a healthy diet can prevent gum diseases.
Your child may have IMPETIGO, a contagious skin infection.
Wash the area 3 or 4 times a day and apply an over-the-counter antibiotic ointment. If the sores spread or don’t get better, call your child’s doctor.
Cold sores will usually go away on their own. Apply an over-the-counter cold sore ointment for comfort. If the sores are painful, give your child an analgesic such as acetaminophen. Avoid pinching, picking or squeezing the blisters.
These may be CANKER SORES. They may be caused by viral infections.
Canker sores usually heal on their own. To relieve discomfort, have your child rinse his or her mouth with salt water or diluted hydrogen peroxide, or apply an over-the-counter oral gel. You may also want to give your child an analgesic such as acetaminophen or ibuprofen to relieve pain. See your child’s doctor if there is no improvement.
These bumps are probably PAPILLAE (where the taste buds are) that have become INFLAMED due to an injury from a burn caused by hot food or drink or a self-inflicted bite.
The inflammation and bump will usually go away on its own. Avoid feeding the child hot, spicy and acidic foods. Give your child an analgesic such as acetaminophen or ibuprofen to relieve pain.
These may be MUCOCELES, harmless cysts that may be caused by sucking mouth tissue between the teeth.

This may be ORAL THRUSH caused by a fungus growing out of control.
This condition usually goes away on its own. Feed your child unsweetened yogurt with live cultures to restore the natural balance of bacteria in the body. Have your child gargle with salt water or use an analgesic such as acetaminophen to relieve pain. If the symptoms get worse or don’t get better, see your child’s doctor. He or she may prescribe an antifungal medicine.

Call your child’s doctor right away.

Your child may have HAND-FOOT-AND-MOUTH DISEASE or HERPANGINA, viral infections caused by the COXSACKIE VIRUS.

Have your child gargle with salt water to relieve discomfort and give your child an analgesic such as acetaminophen to relieve pain and reduce fever. Call your child’s doctor if symptoms get worse or don’t get any better.
