Thumb-Sucking - Exams and Tests
Thumb-sucking behavior before age 3 or 4 is normal and does not require medical tests or evaluation. Children who continue to suck their thumbs after age 4 or 5 may need a:
- Dental exam, to identify any irregularities of the teeth, bite, or jaw.
- Speech evaluation, if word pronunciations are affected or other irregularities develop.
If the habit is severe and appears to be related to other behavioral disorders, such as anxiety, or a reaction from a traumatic event, a psychological evaluation may be needed.
