Thumb-sucking & pacifiers: when to stop

Thumb-sucking and pacifier use are natural self-soothing habits for infants and toddlers, but prolonged use can negatively impact dental development. If these habits continue beyond age 3, they may cause long-term changes in the shape of the mouth, alignment of the teeth and overall bite.

Common orthodontic issues include an open bite (where the front teeth don’t meet), a crossbite (where the upper jaw becomes too narrow), and protruding front teeth, which increase the risk of injury. These changes can also affect speech development, swallowing, breathing (snoring) and facial growth.

The ideal time to stop is between ages 2 and 4, before the adult teeth start coming in. If your child struggles to quit, gentle reminders, rewards and distractions can be effective. If the habit persists past age 5, or you notice changes in tooth positioning, an orthodontic evaluation is recommended.

Seeing an orthodontist by age 7 can help identify bite problems early and prevent more extensive treatment later. In some cases, simple interventions, such as a special appliance, can help break the habit and guide proper jaw development. Addressing these concerns early ensures a healthier, more confident smile for your child as they grow. Please call us for a free consultation if you have any concerns about your child’s bite.
