Effects Of Thumb-Sucking
Apr 11, 2008 Author: Dr Mohamad | Filed under: General Information
Thumb and digit sucking are believed to cause number of changes in the dental arch and the supporting structures. The severity of the malocclusion caused by thumb sucking depends on three factors
A. Duration : The amount of time spent in that habit.
B. Frequency: The number of times the habit is activated in a day.
C. Intensity: The strength with which the habit is performed
Here are some of the effects of thumb sucking
- labial tipping of the maxillary anterior teeth.
- Increased overjet.
- Anterior open bite.
- Cheek muscles contract during thumb sucking.
- Tongue thrust.
In mechanical treatment we can use appliances usually consist of a crib placed palatal to the maxillary incisors , these appliances called ( habit breakers ) and they can be in two types
- Removable habit breakers
- fixed habit breakers
In chemical approach we can use bitter tasting or foul smelling preparation placed on the thumb that is sucked, this can make the habit distasteful

My son has been a thumbsucker for 3 years now! We have tried everything to break the habit..including trying the bitter tasting nail polish…nasty tasting food on his thumb..everything. Nothing works. The kid will suck the nasty tasting stuff off of it and just continue sucking! He will eat just about anything, too..so he does not care about taste! We even had his dentist tell us to put duct tape on his thumbs..we tried it once until the duct tape started to come off in his mouth! His pediatrician said to just keep him occupied but he only does it when he is tired and sleepy..so we cant keep him occupied all night long, lol!! You can already see where his teeth have shaped to his thumb! we dont know what else to do!! his twin sister sucks on her three fingers and we have tried the same things with her! she will cough and gag with the bitter tasting things but then just put her fingers right back in her mouth!!
Dea if you still have the problem with your kids, you should consult an orthodontist. My opinion habit breakers should help.
