Sucking their fingers or thumbs makes young babies feel secure and is completely normal behavior. Babies have been observed to suck their fingers or thumbs even before they are born. But like many comforting habits, over-doing pacifier, thumb, or finger sucking habits may be harmful.

Stop Pacifier Use by 18 Months

Studies have shown that pacifier use after the age of two may cause long-term changes in a child's mouth. We recommend that pacifier use should stop by about 18 months. A pacifier habit is often easier to break than finger or thumb sucking.

Stop Thumb and Finger Sucking by Age Three

Most children naturally stop thumb and finger sucking between two and four years of age, but some children continue this habit much longer. This may cause their upper front teeth to tip towards their lips or to come into position improperly. It can also cause their upper jaw to develop incorrectly. The American Academy of Pediatric Dentistry recommends that children stop these habits by age three.

Use of Behavior Management to Encourage Quitting

We offer creative strategies for gentle ways to cut back and stop pacifier use, including behavior management techniques that use appropriate rewards given at predetermined intervals. Meanwhile, make periodic appointments with us to carefully watch the way your child's teeth and jaws develop.

When your child is old enough to understand the possible results of a sucking habit, just talking about what may happen to teeth as a result can often encourage him/her to quit. As a last resort, a mouth appliance that blocks sucking may be needed.

In times of stress, people have many ways to comfort themselves. For adults, it can be habits such as eating, drinking, or smoking. For children, it is often sucking their thumb, fingers, or a pacifier. Babies have been observed in scans to suck on their fingers and thumbs even before they are born. It makes them feel secure.

When is thumb sucking a problem?
Sucking on fingers or thumbs can be a problem when it is done too vigorously and too long. A young child's jaws are soft and can change their shape to make room for the thumb if the child sucks too hard and too often. If thumb, finger or pacifier habits continue too long, the upper front teeth may tip toward the lip or not come into the correct position in the mouth.

How do you know if your child falls into the group that will suffer from the results of too much thumb sucking? It's best to visit our office so we can check on how the child's teeth and jaws are developing.

What can be done about thumb and finger sucking?
Most children naturally stop sucking their thumbs, fingers, or pacifiers between the age of two and four. The pacifier habit is easier to break than the thumb or finger sucking habit, probably because it is always easier to find their fingers or thumbs. It is a good idea to try to transfer your child's habit to a pacifier at an early age. The next steps are to cut down pacifier usage and gradually stop by 18 months.

If your child is still engaging in these habits at age three, we can recommend strategies for cutting back and stopping. Remember that positive reinforcement, in which a child is rewarded for the desired behavior, always works better than punishment for the behavior you don't like.

Also remember that finger and thumb sucking is normal. Help your child to feel safe, secure, and comfortable as the behavior will probably disappear by itself. If you are worried about your child's sucking a pacifier, thumb or fingers, please visit us to put your mind at rest.

One topic we are often asked about is finger or thumb sucking and/or pacifier use — a challenge that most parents or caregivers will likely face with at least one of their children. The first and perhaps most important thing to remember is that it is totally normal for babies and young children to suck their fingers, thumb or a pacifier. It only becomes a problem when it continues as the child ages or if you unnecessarily make it a problem.

For most children, the sucking instinct starts in the womb before birth. This fact is evident, as many expectant mothers are shown their child sucking fingers or a thumb during a mid or late-term sonogram. Once the child is born, the habit may continue because it provides the child with a sense of security. Other research indicates that some babies start sucking habits as a way to make contact with, test and learn about their new world outside the womb. It is interesting to note that most children typically tend to stop finger or thumb sucking habits on their own and without much intervention between the ages of two and four. However, for others it can continue much longer. And that is the scenario that parents and caregivers need to be aware of so that they can monitor sucking habits.

Children who suck their thumbs or a pacifier after the age of two have a higher risk of developing some long term negative effects from the habit. This includes but is not limited to upper jaw development issues and “buck” teeth (upper front teeth that protrude forward out of a natural position towards the lips). For this reason, some researchers feel that children should cease thumb or finger sucking and/or pacifier use by 18 months of age. However, the Academy of Pediatric Dentistry recommends that parents and caregivers encourage children to cease this habit by age three.
