New born babies normally have the habit of thumb sucking, if this habit continues for a long time it may cause severe damage to oro facial structure. Prolonged thumb-sucking may cause the teeth to become improperly aligned (malocclusion) or push the teeth outward. This usually corrects itself when the child stops thumb-sucking. But the longer thumb-sucking continues, the more likely it is that orthodontic treatment will be needed.

A recent study by New Zealand-based Dunedin School of Medicine says that children who suck thumb and bite nails are less likely to be sensitive to allergies.
