Question

Is it a disease symptom if a two-year-old child has a habit of biting their lower lip? Previous treatment and outcomes: None. Desired assistance: Help break this bad habit.

Answer

Biting the lower lip is indeed an undesirable habit, and if continued for a long time, it can cause the upper incisors to grow forward and downward, while the lower jaw recedes. Since your child is still quite young, it’s best for parents to correct this behavior. Generally, this is done under family care, so it’s important to address and correct this bad habit as soon as possible. If the child grows older, it is recommended to use a proper orthodontic appliance.
