    You see a dentist by the first birthday and stop the pacifier or thumb by one year.

  2. 2. By 2-3

    You stop the pacifier or thumb between two and three.

  3. 3. Child-led

    You let the child give it up when they are ready.

What else is worth knowing?

Dentists suggest a first visit around the first birthday and brushing from the first tooth. Thumb-sucking and pacifiers are normal comforts that can affect teeth if they continue for years. Parents differ on when and how firmly to stop them.
