Along with favorite blankets, teddy bears, and nap time, thumb-sucking can be one of the most comforting aspects of childhood. According to a recent report, between 75% and 95% of infants suck their thumbs, so chances are there’s a thumb-sucker (or a former thumb-sucker) in your family. Is this cause for worry? In most cases, no. However, it’s important to pay attention to your child’s habits, in case his behavior has the potential to affect his oral health.
What Is Normal Thumb-Sucking Behavior?
The majority of children suck a thumb or a finger from a very young age; most even start inside the womb. Sucking is a natural reflex for an infant, and it serves an important purpose. Sucking often provides a sense of security and contentment for a young one. It can also be relaxing, which is why many children suck their thumbs as they fall asleep. According to the American Dental Association, most children stop thumb-sucking on their own between the ages of two and four. They simply grow out of a habit that is no longer useful to them. However, some children continue sucking beyond the preschool years (although studies show that the older a child gets, the lower his chances of continuing to suck his thumb). If your child is still sucking when his permanent teeth start to erupt, it may be time to take action to break the habit.
