Question
I noticed a few white blisters on my child’s lower lip, which were not there yesterday. Our home uses a heated bed, and I suspect it might be too hot. The child is breastfed, and recently I’ve had some diarrhea. I’m worried this might affect his health.
Answer
White blisters on the lips may be caused by damage to the oral mucosa. Common causes include smoking, drinking alcohol, spicy food, excessive heat, or poor dental treatment. This condition may also be a type of oral mucosal disease, and it is recommended to undergo a detailed examination at a dental hospital. First, it is necessary to rule out factors that cause mucosal damage, such as taking vitamin A or retinoic acid orally. Cod liver oil can also be used to apply to the affected area. If symptoms persist and the white patch area develops cracks, ulcers, or hardening of the base, early surgical removal should be considered. Usually, the recurrence rate after surgery is low.
