Question
Recently, parents have noticed that their baby often bites their lower lip with their upper gum, and they are seeking medical advice.
Answer
This behavior in babies may be due to teething, causing sore gums, or because the baby is beginning to explore their own body, particularly their mouth area. If teething is confirmed as the cause, it is suggested to provide a teething toy to alleviate gum discomfort. Additionally, the behavior of exploring the body is a normal part of growth, and parents should not intervene excessively. They simply need to prepare oral cleaning supplies. As the baby’s curiosity about their body diminishes, this type of behavior will naturally decrease.
