This can manifest in localised dental anomalies such as an open bite, crossbites and protruded top front teeth. The good news is that if this habit is stopped early enough, these dental issues usually self-resolve. However, it can sometimes be very difficult for a child to stop – we all know how difficult it is to stop a habit. This is why it is important for a child to see an orthodontist early to assess the damage that has been done to the teeth and jaws, to encourage the child to stop and if necessary, intervene with appropriate treatment to gently help them to cease the habit.
