Thumb Sucking

thumb sucking

Thumb sucking is a common habit among many children.  It is common with children under three and is associated with the need to seek food.  In some infants it can signal fatigue, sleep, hunger, teething and shyness.

Thumb sucking and it’s effect

thumb teethThirty percent of preschool children continue the habit. Most kids out grow it by 5 to 7 years of age.  It is may be harmful if child is still doing it at the time their permanent teeth are coming in, which is usually around 6 years.

It is generally done by child when they are:

  • Bored
  • Tired
  • Worried
  • Feeling stressed

The intensity and frequency of thumb sucking is a factor which determines whether or not dental problems may occur.  Vigorous thumb suckers will have more dental problems.

The possible effects of thumb sucking for children after the age of three is
  • Thumb SuckingReshape the jawbone because their jawbones are still soft and pliable
  • Teeth grow out of aliment and position
  • Narrows dental arches which cause the next problem
  • Upper front teeth will flare out and tip upward ,this makes them prone for trauma.
  • Lower teeth will move inward
  • Affect growth of child’s palate (roof of the mouth) causing:
    1. Poor tongue placement
    2. Problems chewing
    3. Problems with learning to swallow properly.
    4. Problems speaking
    5. Overbite or open bite.
    6. Make tonsils collapse to cause snoring.
    7. The skeletal deformities which can develop can lead to insecurities and self-image problems, particularly in children.
    8. Cause infections to develop around fingernails to spread infectious diseases.

The tongue plays a major role in swallowing. For people who don’t suck their thumb or finger, their tongue goes up behind the roof of their mouth as they swallow and this causes a seal. But, when trying to swallow while sucking the thumb or finger, the tongue is thrust forward, in between the front teeth. This action makes swallowing difficult and will require re-training to correct the tongue movement.

Breaking the habit

It is important to stop the thumb sucking habit BEFORE permanent teeth come in.  Breaking the habit sooner will make it easier for you, the parent, your child and their mouth! If they can not stop on their own, by the ages of three to four, they may need help
