For many young children, thumb sucking is a natural and comforting habit. It can help them feel safe, fall asleep more easily, or calm down when they’re upset. Most children grow out of the habit on their own, but when thumb sucking continues beyond the early years, it may begin to affect dental development.
At Mackenzie Orthodontics, we often meet parents who wonder when thumb sucking becomes a concern and what they can do to help their child stop. Here’s what you need to know.
When Is Thumb Sucking Normal?
Thumb sucking is extremely common in babies and toddlers. Most children naturally stop between the ages of 2 and 4. At this stage, it’s rarely harmful because their teeth and jaws are still developing.
However, if the habit continues beyond age 5 or 6, when permanent teeth begin to come in, it can start to cause orthodontic issues.
How Thumb Sucking Affects Teeth and Jaws
Persistent thumb sucking puts pressure on the front teeth and the roof of the mouth. Over time, this can lead to:
- Protruding front teeth
- An open bite, where the front teeth don’t touch when the mouth is closed
- Changes in jaw shape, such as narrowing of the upper jaw
- Speech issues, like difficulty pronouncing certain sounds
The longer the habit continues, the greater the risk of long-term orthodontic problems.
When to See an Orthodontist
If your child is over the age of 5 and still sucks their thumb regularly, it may be time to consult an orthodontist. Early intervention can prevent more significant problems later and may even reduce the need for extensive treatment down the road.
