Why stop thumb sucking?

 

There are many parents concerned about their child still sucking their thumb when most people have the opinion that they shouldn’t.  This can be frustrating, confusing, upsetting and even undermining to a parent.   My hat off to the parent with great internal fortitude to ignore others’ comments and not feel compelled or pressured to address something that until now has not been an issue for themself or their child., and instead to recognise when the time is right for them.

 

Remember a parent is doing their best with what they have and what they know in the circumstances they find themselves at this point of time.

 

The timing of when this is a concern varies . For some it is when their baby starts to suck his or her thumb or finger. For others it is 12 months and others still not until about 5 or 6 years of age.

Generally it seems to be sometime before adult teeth erupt.  Tis would put it about 6 or 7 years of age.  Many would recommend that from age 5 years if thumb or finger sucking is an obvious issue, do not let it go past this age before you start to address the problem.

As a child health nurse we would become aware of it and monitor it from 12 months on and as the child matures, utilise non invasive habits to discourage it.

 

Why is it of such concern?  Most concerns tend to be about teeth and skeletal development  of the mouth. The risk is that pressure from the thumb can eventually change the shape of the growing jaw and cause things such as overbite, or buck teeth or  uneven or mispositioned teeth.

 

It may also interfere with speech.  The tongue is a muscle so if it is worked for lengthy periods in the wrong way it may become thicker in some areas and cause speech problems.  in some instances  it may cause a delay in speech development and others inducing a lisp or mis pronounciation of certain sounds.

 

Ideally we would like thumb sucking to stop somewhere between 2 and 4 years.  As long as it is stopped before adult teeth come through. If left unchecked  it can go to adulthood.
