Thumb- or finger-sucking is much more of a problem with one in eight children over the age of seven having a prolonged habit.
Soother habits are usually gone by the time the adult teeth start to appear at 6 years of age. The commonest effect for the baby teeth is an “open bite” between the upper and lower front teeth.
As long as the habit is stopped by the age of six, these effects may sometimes improve spontaneously.
If the habit persists, orthodontic problems can occur and it is best to seek advice from your dentist who may be able to give some direct counselling to your child…sometimes that can do the trick!
This also gives a baby a “sweet tooth” at an early age which can lead to further sugar consumption in later years.
