Consulate Dental Plans – Adult Thumb and or Finger Sucking.
An adult might suck their thumb because of stress, anxiety, or age regression. Over time, this habit may cause blisters or problems with the teeth.
Over time, thumb sucking can also lead to someone’s teeth moving out of alignment, according to the American Dental Association (ADA). Some people can also develop an overbite.
Dental problems are more common in those who suck their thumb more intensely. Having the thumb passively in the mouth is less likely to lead to tooth misalignment.
