Question
At two years old, my child has a habit of biting their lower lip. Is this a sign of a disease? What has been the past treatment and its effectiveness? What kind of help am I looking for?
Answer
Biting the lower lip is indeed an undesirable habit that could lead to the upper jaw teeth growing forward and downward, while the lower jaw may recede backward. Since your child is still quite young, this situation usually requires correction under parental care. It is very important to correct this mistake as soon as possible. If your child grows up with this habit, it is recommended to seek professional corrective treatment.
