Sucking one’s thumb over time can often cause problems in the way that teeth develop, at least if the habit persists. Derek M. Busciglio, D.M.D., runs Busciglio Orthodontics, bringing smiles throughout the Brandon, Florida and Plant City, Florida areas. Here, he talks about whether or not you should be worried if your child is a persistent thumbsucker.
Thumbsucking is a common habit that usually begins about three months of age, signaling fatigue, sleep, hunger, teething or shyness. Experts say that thumbsucking does mean a child is insecure or has emotional problems. Rather, usually, its repetitive nature brings the child comfort.
While approximately 30% of preschool children continue the habit, most children outgrow thumbsucking by age five. The American Dental Association advises that children can probably suck their thumb until they are four or five years old without damaging their teeth or jaw line.
However, after a child’s permanent teeth come in, at age six or seven, excessive thumbsucking must be stopped to prevent possible dental problems. Problems can include:
- An overbite or buck teeth which can alter the shape of the face
- Teeth that may grow out of alignment and positioning
- Upper teeth that may flare out and tip upward
- Lower teeth that may move inward
- A lisp that may interfere with the correct formation of certain speech sounds
To help children stop thumbsucking, expert suggestions include offering rewards, encouragement, and gentle reminders and distractions to occupy children.
Dealing With Pacifiers
If your child consistently relies on a pacifier for comfort, it is best to ration it out. Rationing methods can include only letting your child suck a pacifier when he is trying to fall sleep, and taking it out of the crib when he is awake. Remember, a child usually cannot get access to a pacifier unless you provide it.
Experts say children should not have pacifiers after age one, although many parents balk at the idea. Whatever you do, it is imperative never to dip the pacifier into any sugary substance before allowing your child to suck it, such as molasses, maple syrup, or fruit juice. Sucking sugary things before bedtime can result in serious tooth decay. See your dentist if you have any other concerns.
