One of the biggest concerns we hear from parents is about their child's thumb sucking habit. Our advice: if they're under age 4, there's no need for concern — yet. If they're older, though, you should be concerned about the possible effect on their bite.
Thumb sucking is a universal habit among infants and toddlers and is related to their swallowing pattern during feeding. As they swallow, their tongue thrusts forward to create a seal with the lips around the breast or a bottle nipple. Many pediatricians believe thumb sucking replicates nursing and so has a comforting effect on infants.
Around age 4, though, this swallowing pattern begins to change to accommodate solid food. The tongue now begins to rest at the back of the top front teeth during swallowing (try swallowing now and you'll see). For most children, their thumb sucking habit also fades during this time and eventually stops.
But for whatever reason, some children don't stop. As the habit persists, the tongue continues to thrust forward rather than toward the back of the top front teeth. Over time this can place undue pressure on both upper and lower front teeth and contribute to the development of an open bite, a slight gap between the upper and lower teeth when the jaws are shut.
While late childhood thumb sucking isn't the only cause for an open bite (abnormal bone growth in one jaw is another), the habit is still a prominent factor. That's why it's important that you start encouraging your child to stop thumb sucking around age 3 and no later than 4. This is best accomplished with positive reinforcement like rewards or praise.
If they've continued the habit a few years after they should have stopped, we may also need to check to see if their swallowing mechanism has become stunted. If so, we may need to use certain exercises to retrain their tongue to take the proper position during swallowing.
While you shouldn't panic, it's important to take action to stop thumb sucking before it becomes a long-term problem. A positive, proactive approach will help avoid costly orthodontic problems later in their lives.

It's no secret that many of Hollywood's brightest stars didn't start out with perfectly aligned, pearly-white teeth. And these days, plenty of celebs are willing to share their stories, showing how dentists help those megawatt smiles shine. In a recent interview with W magazine, Emma Stone, the stunning 28-year-old star of critically-acclaimed films like La La Land and Birdman, explained how orthodontic appliances helped her overcome problems caused by a harmful habit: persistent thumb sucking in childhood.
“I sucked my thumb until I was 11 years old,” she admitted, mischievously adding “It's still so soothing to do it.” Although it may have been comforting, the habit spelled trouble for her bite. “The roof of my mouth is so high-pitched that I had this huge overbite,” she said. “I got this gate when I was in second grade… I had braces, and then they put a gate.”
While her technical terminology isn't quite accurate, Stone is referring to a type of appliance worn in the mouth which dentists call a “tongue crib” or “thumb/finger appliance.” The purpose of these devices is to stop children from engaging in “parafunctional habits” — that is, behaviors like thumb sucking or tongue thrusting, which are unrelated to the normal function of the mouth and can cause serious bite problems. (Other parafunctional habits include nail biting, pencil chewing and teeth grinding.)
When kids develop the habit of regularly pushing the tongue against the front teeth (tongue thrusting) or sucking on an object placed inside the mouth (thumb sucking), the behavior can cause the front teeth to be pushed out of alignment. When the top teeth move forward, the condition is commonly referred to as an overbite. In some cases a more serious situation called an “open bite” may develop, which can be difficult to correct. Here, the top and bottom front teeth do not meet or overlap when the mouth is closed; instead, a vertical gap is left in between.
Orthodontic appliances are often recommended to stop harmful oral habits from causing further misalignment. Most appliances are designed with a block (or gate) that prevents the tongue or finger from pushing on the teeth; this is what the actress mentioned. Normally, when the appliance is worn for a period of months it can be expected to modify the child's behavior. Once the habit has been broken, other appliances like traditional braces or clear aligners can be used to bring the teeth into better alignment.
But in Stone's case, things didn't go so smoothly. “I'd take the gate down and suck my thumb underneath the mouth appliance,” she admitted, “because I was totally ignoring the rule to not suck your thumb while you're trying to straighten out your teeth.” That rule-breaking ended up costing the aspiring star lots of time: she spent a total of 7 years wearing braces.
Fortunately, things worked out for the best for Emma Stone: She now has a brilliant smile and a stellar career — plus a shiny new Golden Globe award!

As a parent you’re concerned with a number of issues involving your child’s health, not the least of which involves their teeth. One of the most common is thumb-sucking.
While later thumb-sucking is a cause for concern, it’s quite normal and not viewed as harmful in infant’s and very young children. This universal habit is rooted in an infant swallowing pattern: all babies tend to push the tongue forward against the back of the teeth when they swallow, which allows them to form a seal while breast or bottle feeding. Infants and young children take comfort or experience a sense of security from sucking their thumb, which simulates infant feeding.
Soon after their primary teeth begin to erupt, the swallowing pattern changes and they begin to rest the tongue on the roof of the mouth just behind the front teeth when swallowing. For most children thumb sucking begins to fade as their swallowing pattern changes.
Some children, though, continue the habit longer even as their permanent teeth are beginning to come in. As they suck their thumb the tongue constantly rests between the front teeth, which over time may interfere with how they develop. This can cause an “open bite” in which the upper and lower teeth don’t meet properly, a problem that usually requires orthodontic treatment to correct it.
For this reason, dentists typically recommend encouraging children to stop thumb-sucking by age 3 (18-24 months to stop using a pacifier). The best approach is positive reinforcement — giving appropriate rewards over time for appropriate behavior: for example, praising them as a “big” boy or girl when they have gone a certain length of time without sucking their thumb or a pacifier. You should also use training or “Sippy” cups to help them transition from a bottle to a regular cup, which will further diminish the infant swallowing pattern and need for thumb-sucking.
Habits like thumb-sucking in young children should be kept in perspective: the habit really isn’t a problem unless it goes on too long. Gentle persuasion, along with other techniques we can help you with, is the best way to help your child eventually stop.

Thumb or finger sucking is a normal activity for babies and young children — they begin the habit while still in the womb and may continue it well into the toddler stage. Problems with tooth development and alignment could arise, however, if the habit persists for too long.
It’s a good idea, then, to monitor your child’s sucking habits during their early development years. There are also a few things you can do to wean them off the habit before it can cause problems down the road.
- Eliminate your child’s use of pacifiers by eighteen months of age. Studies have shown that the sucking action generated through pacifiers could adversely affect a child’s bite if they are used after the age of 2. Weaning your child off pacifiers by the time they are a year and a half old will reduce the likelihood of that occurring.
- Encourage your child to stop thumb or finger sucking by age 3. Most children tend to stop thumb or finger sucking on their own between the ages of 2 and 4. As with pacifiers, if this habit continues into later childhood it could cause the upper front teeth to erupt out of position and tip toward the lip. The upper jaw also may not develop normally.
- Replace your child’s baby bottle with a training cup around one year of age. Our swallowing mechanism changes as we grow; introducing your child to a training cup at around a year old will encourage them to transition from “sucking” to “sipping,” and make it easier to end the thumb or finger sucking habit.
- Begin regular dental visits for your child by their first birthday. The Age One visit will help you establish a regular habit of long-term dental care. It’s also a great opportunity to evaluate your child’s sucking habits and receive helpful advice on reducing it in time.
While your child’s thumb or finger sucking isn’t something to panic over, it does bear watching. Following these guidelines will help your child leave the habit behind before it causes any problems.

One of the most common parental concerns is the habit of many children, even late into childhood, to suck their thumbs or fingers. Many parents have asked us, “Could this affect their teeth?”
The answer, unfortunately, is yes — thumb sucking can contribute to a malocclusion (bad bite) that could eventually require orthodontic treatment. Before making any assumptions, however, we need to understand the bigger picture.
To begin with, infants have a different swallowing mechanism than adults and older children. When you as an adult swallow, you'll notice the tip of your tongue positions itself just above the back of the top front teeth. An infant, however, will thrust their tongue between their upper and lower jaw as they swallow (also known as an infantile swallowing pattern or primary tongue thrust). The infant normally begins changing to an adult swallowing pattern when their primary (baby) teeth begin to erupt.
However, if a child's swallowing transition is slower than normal and the tongue rests between the jaws for a longer duration, it can inhibit the full eruption of teeth, believed to be the main cause of an open bite (a gap between the upper and lower teeth when the jaws are shut). The thumb during sucking resting between the teeth can have the same effect.
Thumb sucking may not necessarily lead to a malocclusion — for example, an abnormally developing jawbone could be the culprit. If prolonged thumb sucking does become a concern, however, there are steps we can take to reduce the impact of the habit. We can install a thin metal “tongue crib” behind the upper and lower incisors that will not only discourage thumb sucking, but also help retrain the tongue not to rest between the upper and lower teeth. There are also exercise routines known as orofacial myofunctional therapy (OMT) that can retrain specific muscles in the mouth to encourage more normal chewing and swallowing patterns.
These steps may not prevent future orthodontic treatment, but they could reduce its extent. The key is regular dental checkups and consultation to ensure your child's teeth and bite are developing normally.
