It’s true — thumb sucking beyond age 4 can cause bite problems for permanent teeth. But prolonged thumb sucking is just one of a number of possible contributing factors for a bad bite (malocclusion). A dentist must identify all the factors involved when a bad bite is present — their involvement is essential for a successful treatment outcome.
A fairly benign habit for infants and toddlers, thumb sucking is related to an “infantile swallowing pattern” young children use by thrusting their tongues forward between the upper and lower teeth when they swallow. Around age 4, though, they usually transition to an adult swallowing pattern in which the tongue rests on the roof of the mouth just behind the front teeth. Thumb sucking stops for most children around the same time.
Thumb sucking beyond this age, though, can put increased pressure on incoming permanent teeth pushing them forward. This could lead to an “open bite” in which the upper and lower teeth don’t meet when the jaws are closed. The tongue may also continue to thrust forward when swallowing to seal the resulting gap, which further reinforces the open bite.
Before treating the bite with braces, we must first address the thumb sucking and improper tongue placement when swallowing — if either isn’t corrected the teeth could gradually revert to their previous positions after the braces come off. Besides behavioral incentives, we can also employ a thin metal appliance called a “tongue crib” placed behind the upper and lower incisors. A tongue crib discourages thumb sucking and makes it more difficult for the tongue to rest within the open bite gap when swallowing, which helps retrain it to a more normal position.
An open bite can also occur if the jaws develop with too much vertical growth. Like thumb sucking and improper tongue placement, abnormal jaw growth could ultimately cause orthodontic treatment to fail. In this case, though, surgery may be necessary to correct the jaw structure.
With all these possible variables, our first step needs to be a thorough orthodontic exam that identifies all the cause factors for your child’s specific malocclusion. Knowing if and how thumb sucking may have contributed to the poor bite will help us design a treatment strategy that’s successful.

Whether she’s singing, dancing or acting, Jennifer Lopez is a performer who is known for giving it all she’s got. But during one show, Lopez recently admitted, she gave a bit more then she had planned.
“I chipped my tooth on stage,” she told interviewers from Entertainment Tonight, “and had to finish the show….I went back thinking ‘Can I finish the show like this?’”
With that unlucky break, J-Lo joins a growing list of superstar singers—including Taylor Swift and Michael Buble—who have something in common: All have chipped their teeth on microphones while giving a performance.
But it’s not just celebs who have accidental dental trouble. Chips are among the most common dental injuries—and the front teeth, due to their position, are particularly susceptible. Unfortunately, they are also the most visible. But there are also a number of good ways to repair chipped, cracked or broken teeth short of replacing them.
For minor to moderate chips, cosmetic bonding might be recommended. In this method, special high-tech resins, in shades that match your natural teeth, are applied to the tooth’s surface. Layers of resin, cured with a special light, will often restore the tooth to good appearance. Best of all, the whole process can often be done in just one visit to the dental office, and the results can last for several years.
For a more permanent repair—or if the damage is more extensive—dental veneers may be another option. Veneers are wafer-thin shells that cover the entire front surface of one or more teeth. Strong, durable and natural-looking, they can be used to repair moderate chips, cracks or irregularities. They can also help you get a “red-carpet” smile: brilliant white teeth with perfectly even spacing. That’s why veneers are so popular among Hollywood celebs—even those who haven’t chipped their teeth!
Fortunately, even if the tooth is extensively damaged, it’s usually possible to restore it with a crown (cap), a bridge—or a dental implant, today’s gold standard for whole-tooth replacement. But in many cases, a less complex type of restoration will do the trick.
Which tooth restoration method did J-Lo choose? She didn’t say—but luckily for her adoring fans, after the microphone mishap she went right back up on stage and finished the show.
If you have a chipped tooth but you need to make the show go on, please contact us or schedule an appointment for a consultation. You can also learn more by reading the Dear Doctor magazine articles “Artistic Repair of Chipped Teeth With Composite Resin” and “Porcelain Veneers.”
Biting the inside of your cheek is high on the list of minor but painfully irritating occurrences like paper cuts or tongue scalding from hot coffee. A mouth bite, though, has an additional tormenting feature — there's a good chance you'll bite the same spot again.
This kind of repeated mouth injury results in an enlargement of the soft tissue that has been traumatized. They're often diagnosed and referred to as a traumatic fibroma. When you bite your cheek, lips or tongue, you create a small wound that usually heals quickly. This healing process, though, can be interrupted if you bite the area again, which can then cause excess scar tissue to form.
The fibrous scar tissue, made up of a protein called collagen, is similar to a callous. You can often feel it with your tongue — a knot of tough skin that protrudes from the otherwise flat cheek wall. Because of this prominence, it tends to get in the “line of fire” during eating or biting, so you'll bite it again — and again. If this cycle continues, then even a more prominent scar tissue forms that you're more likely to bite again.
The wound will heal most of the time, unless you continually bite it. If it becomes a nagging problem, we can surgically remove the lump. After numbing the area with local anesthesia, we'll either use a laser or scalpel to remove it. The area is easy to fix and will flatten out the cheek surface. The entire procedure takes fifteen minutes or less and in a few days to a week you won't even notice it had been there.
While the vast majority of these lesions are harmless, it's still standard protocol to biopsy the removed tissue: a pathologist examines it under a microscope for cancer cells. This is a routine part of any medical practice and not a cause for alarm.
If you've had a lump for awhile that you always seem to be biting, see us for an examination. With a simple procedure, we may be able to remove that irritation once and for all.
