Thumb Sucking and Dummy Use: When Should They Stop?

Thumb sucking and dummy use are very common in babies and young children. These habits are a normal way for young children to comfort and soothe themselves, particularly when they are tired, upset or settling to sleep.

For most children, thumb sucking and dummy use are not a concern during infancy and the toddler years. Many children naturally stop on their own as they grow older.

Problems are more likely to occur if the habit continues after the permanent teeth begin to develop, particularly beyond the age of four. Prolonged thumb sucking or dummy use can affect the way the jaws grow and how the teeth come together. It may contribute to an increased overjet (protruding front teeth), an open bite where the front teeth do not meet, changes to the shape of the upper jaw and, in some children, speech difficulties. Protruding front teeth are also more vulnerable to injury if your child has a fall or knocks their mouth during play or sport.

If your child is finding it difficult to stop, encouragement and positive reinforcement are usually more effective than punishment. Praising your child for not sucking their thumb, using reward charts and gradually reducing dummy use can all help make the transition easier. Some families find it helpful to limit dummy use to bedtime before stopping altogether.

How can your Dentist/Oral Health Therapist help?

Regular dental check ups allow your dental clinician to monitor your child’s growth and development and identify any changes to the teeth or jaws. If thumb sucking or dummy use is continuing as your child gets older, your dental clinician can provide advice and discuss strategies to help break the habit.

Every child develops at their own pace, and many stop these habits naturally. If you have concerns about your child’s thumb sucking or dummy use, speak with your dental clinician. Early guidance can help support healthy dental development while making the transition as smooth as possible for both you and your child.
