Are you struggling to get your child to stop thumb-sucking? You’re not alone. Sucking thumb is a common habit among young children, but it’s essential to break thumb sucking habit to prevent dental issues and social challenges. NIPIT will help you to explore practical solutions to help your child break the thumb-sucking habit for good.

Reasons Why Do Babies Suck Their Thumbs?

It is usual for children to thumb-suck. It’s a natural reflex that provides comfort, security, and a sense of familiarity. These are a few reasons why children suck their thumbs:

Comfort and Soothing

  • Babies frequently self-soothe by sucking their thumbs. It gives them a sense of security and comfort, especially when tired, anxious, or upset.

Mimicking Womb Experience

  • Thumb sucking may also mimic the comforting feeling of being in the womb. Babies are used to sucking in the womb, so they continue this behaviour after birth.

Exploration and Stimulation

  • Sucking thumb is also a way for babies to explore and learn about their bodies. It provides them with sensory stimulation, which is a natural part of their development.


  • Sometimes, babies may suck their thumbs because they are hungry. It’s their way of signalling their need for food.


  • Teething can also be a reason for thumb-sucking. Babies may suck their thumbs to relieve the discomfort caused by teething.
Preventing Thumb Sucking

Effects of Excessive Thumb-Sucking on Child’s Dental Health

Excessive thumb-sucking can have many effects on the teeth and mouth. This is due to the constant pressure that sucking and the thumb apply to the teeth, jawbone, and roof of the mouth. 

1. Misalignment of Teeth

It can cause misalignment of teeth. The constant pressure from the thumb can push the teeth out of their proper position, resulting in an open bite, overjet, or other orthodontic issues.

2. Overbite and Open Bite

It can also contribute to the development of an overbite or an open bite. When a child sucks their thumb, it can push the top front teeth forward, leading to an overbite. Alternatively, it can cause the front teeth to tilt outward, creating an open bite.

3. Narrowing of the Dental Arch

The pressure exerted by the thumb can cause the dental arch to narrow. This can result in crowding or misaligning teeth, requiring orthodontic intervention to correct.

4. Speech Problems

Thumb sucking can affect speech development. The positioning of the thumb in the mouth can interfere with the proper formation of sounds, leading to speech impediments such as lisps or difficulty pronouncing certain words.

5. Palatal Changes

The constant pressure from thumb-sucking can also affect the shape of the palate. Prolonged thumb-sucking may lead to changes in the roof of the mouth, resulting in a high, arched palate.
