this temporary relief can have serious consequences. Most children stop sucking their thumb by 2 and 1/2 years of age and it is even considered normal until ages 3 to 4. However, when the finger habit persists beyond the toddler years and into the adolescent years there can be significant effects on the teeth, gums, jaws, and even facial form.
Prolonged thumb sucking turns into a habit which can cause a dental and even a skeletal open bite. If the habit ceases while the child is still growing the dental open bite can self correct but sometimes the help of an orthodontist is required to correct the position of the teeth. But if the habit continues or the open bite does not correct while the child is still growing then the jaws "solidify" in the open position. If the open bite is not corrected while your child is growing then jaw surgery may be required to correct the bite.
Think about it, a seemingly harmless act as a child can change the facial form of your child for life and result in various respiratory, dental, and speech problems - your child would not be able to bite into a sandwhich or a famous New York City pizza slice. Not Good.
What can be done? Like I said in the beginning until age 4 this finger habit is considered normal but if it persists discuss with your child ways in stopping it. Various over the counter treatments can be found at the drugstore. Try to find out why your child has continued the habit - look for the etiology. If it continues seek advice from your dentist or orthodontist. Many times there are retainer type devices that can stop the habit and prevent some of the ill effects and eventual jaw surgery.
