Thumb Sucking and Dummies: How Can They Affect Your Child’s Teeth?

Breaking a habit can be difficult, particularly when it provides comfort. The British Orthodontic Society recommends a positive, supportive approach.

Here are seven practical strategies to help.

• Encourage rather than criticise

Explain gently why stopping is important. Avoid nagging, teasing, punishing or embarrassing your child.

• Use a reward chart

Create a colourful sticker chart and reward your child for periods without thumb sucking. Small daily achievements can build motivation.

• Praise their progress

Recognise when your child manages without sucking their thumb. Positive encouragement helps build confidence.

• Identify when the habit happens

Notice whether your child sucks their thumb when tired, bored or anxious. Offer alternative comfort, such as a favourite toy, cuddle or bedtime story.

• Try gentle physical reminders

For children who want to stop, the BOS suggests reminders such as:

• A sticky plaster or bandage.
• A cotton glove or sock.
• A suitable thumb guard.
• Bitter-tasting nail varnish designed for discouraging nail biting or thumb sucking.

Choose age-appropriate, safe options and use them with your child’s cooperation.

• Tackle daytime habits first

Children often stop sucking their thumbs during the day before managing to stop at night. Celebrate daytime progress rather than expecting immediate success.

• Involve your child

Most importantly, your child needs to want to stop. Talk to them about what might help and involve them in choosing rewards and reminders.

Patience and encouragement are far more helpful than pressure.
