Blisters on the inside of your 1-year-old's lip can be bothersome, especially if they are painful. Blisters can be caused by many factors and conditions, some that can be dangerous if left untreated. Because blisters can be stressful for your child, it is important to understand what triggers them and how you can ease symptoms.
Signs
A blister on the inside of your 1-year-old's lips can range from tiny to large. It can develop as a single blister or appear in clusters. Blisters can also occur on your child's gums, cheeks, tongue or the soft tissue on the roof of his mouth. Blisters can appear yellowish or red in color, with a crusty, open sore in the center.
Triggers
A canker sore, which is an ulcer of the mouth, can develop if your child is under stress. A burn, bite or injury to the inside of the mouth can cause a blister called a papillae. If your child sucks on the skin in his mouth, the tissue can become inflamed and result in a cyst called a mucocele. Some fungus or viral infections, such as oral thrush, impetigo and herpes, can also trigger blisters inside of your toddler's mouth. In addition, they can be a sign of an allergic reaction.
Treatment Options
Rinse your child's mouth out with water or wash the wound with gauze dipped in water several times a day. Apply an oral gel to the blister to help ease symptoms. Give your child an analgesic medication, like children's ibuprofen, to treat inflammation and pain. If your child's lip blisters are caused by a viral or fungal infection, your pediatrician may prescribe antibiotics to help speed up the healing process.
Dangers
Go to the emergency room or call 911 if your child develops blisters on the inside of his lips and experiences problems breathing, difficulty swallowing or passes out. These could be symptoms of a serious problem, such as anaphylaxis. Your baby may require an emergency injection of epinephrine to immediately relax the muscles of his airway and improve blood flow to vital parts of the body, such as the brain and heart.
