How Can Thumb Sucking Affect My Child’s Teeth?

  • After permanent teeth come in, sucking may cause problems with the proper growth of the mouth and alignment of the teeth. It can also cause changes in the roof of the mouth.
  • Pacifiers can affect the teeth essentially the same ways as sucking fingers and thumbs, but it is often an easier habit to break.
  • The intensity of the sucking is a factor that determines whether or not dental problems may result. If children rest their thumbs passively in their mouths, they are less likely to have difficulty than those who vigorously suck their thumbs. Some aggressive thumb suckers may develop problems with their baby (primary) teeth.

When Should Children Stop Sucking Their Thumbs?

  • Children usually stop sucking between the ages of two and four years old, or by the time the permanent front teeth are ready to erupt. If you notice changes in your child’s primary teeth, or are concerned about your child’s thumb sucking please call our office to schedule an appointment.
