Sucking is a natural reflex that comforts babies and helps them fall asleep. For most children, thumb-sucking or using a dummy is harmless in the early years. Problems tend to appear when the habit continues as the adult teeth start to come through.
How can sucking habits affect teeth?
Frequent, strong sucking past the age of about four can:
- Push the top front teeth forward and the bottom teeth back
- Create an “open bite”, where front teeth don’t meet when biting
- Narrow the upper jaw, affecting how the back teeth fit together
- Affect speech, such as a lisp
Dummy or thumb: is one better?
A dummy can be easier to wean off, because you can take it away. A thumb is always available. If your child uses a dummy, choose an orthodontic shape. Never dip it in sugar or honey.
Helping your child stop
- Praise and reward the days without sucking, using a sticker chart.
- Notice when your child sucks out of boredom or tiredness, and offer comfort or a distraction.
- For thumb-sucking at night, a glove or plaster on the thumb can act as a reminder.
- Avoid scolding, which can increase anxiety and make the habit stronger.
When to ask the dentist
If your child is still sucking a thumb or dummy as adult front teeth arrive, around age six, mention it at their check-up. We can look at how the teeth are developing and talk to your child about stopping. Early changes often correct themselves once the habit stops.
