Thumb sucking is a common habit for babies and toddlers, but if it continues beyond the age of three, it can lead to significant dental issues. In a healthy mouth, the upper teeth slightly overlap the lower teeth. However, persistent thumb sucking puts pressure on the gums, which can affect the way the teeth erupt and potentially interfere with the growth of the jawbone.
In some cases, prolonged thumb sucking can cause an open bite, a dental condition where the teeth do not overlap naturally when the mouth is closed. It can also lead to misalignment of the teeth, changes in the roof of the mouth, and even speech difficulties.
