There's something universal about thumb sucking: nearly all babies do it, and nearly all parents worry about it. While most such worries are unfounded, you should be concerned if your child sucks their thumb past age of 4 — late thumb sucking could skew bite development.
Young children suck their thumb because of the way they swallow. Babies move their tongues forward into the space between the two jaws, allowing them to form a seal around a nipple as they breast or bottle feed. Around age 4, this “infantile swallowing pattern” changes to an adult pattern where the tip of the tongue contacts the front roof of the mouth just behind the front teeth. At the same time their future bite is beginning to take shape.
In a normal bite the front teeth slightly overlap the bottom and leave no gap between the jaws when closed. Â But if thumb sucking continues well into school age, the constant pushing of the tongue through the opening in the jaws could alter the front teeth's position as they erupt. As a result they may not fully erupt or erupt too far forward. This could create an open bite, with a gap between the upper and lower teeth when the jaws are closed.
Of course, the best way to avoid this outcome is to encourage your child to stop thumb sucking before they turn four. If, however, they're already developing a poor bite (malocclusion), all is not lost — it can be treated.
It's important, though, not to wait: if you suspect a problem you should see an orthodontist for a full evaluation and accurate diagnosis. There are even some measures that could discourage thumb sucking and lessen the need for braces later. These include a tongue crib, a metal appliance placed behind the upper and lower incisors, or exercises to train the tongue and facial muscles to adopt an adult swallowing pattern. Often, a reward system for not sucking their thumbs helps achieve success as well.
Thumb-sucking shouldn't be a concern if you help your child stop before age 4 and keep an eye on their bite development. Doing those things will help ensure they'll have both healthy and straight teeth.

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!
