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.

Even the sweetest children don’t always have sweet-smelling breath. If your child has persistent bad breath, it may be for one of the following reasons:
POOR ORAL HYGIENE HABITS. Bad breath often results from bacteria on the teeth and tongue that is not effectively removed during brushing and flossing.
- Tip: To encourage thorough cleaning as children are developing their oral hygiene habits, try handheld flossers that are colorful and easy to use, sing or play music to make brushing time fun, or try an electric toothbrush with a timer or a tooth-brushing app that keeps kids brushing for a full two minutes.
PLAQUE BUILDUP, TOOTH DECAY AND GUM DISEASE: Plaque, a sticky bacterial biofilm, can build up on tooth surfaces, between the teeth and under the gum line and can lead to tooth decay and gum disease. These conditions may result in bad breath.
- Tip: Stay on top of your child’s oral hygiene at home, and keep up with regular dental visits for professional cleanings and checkups.
POST-NASAL DRIP: This common cause of foul-smelling breath in children results when excessive mucus is produced and drips down the back of the throat.
- Tip: Schedule an appointment with your child’s pediatrician to determine and treat the cause.
MOUTH BREATHING. Breathing through the mouth instead of the nose can cause a dry mouth. This can lead to increased oral bacteria, which can cause bad breath. If children breathe through the mouth all the time, not just because of a temporary cold or allergies, your child is at greater risk for tooth decay and gum disease.
- Tip: If your child is a chronic mouth breather, schedule a dental visit so we can check for any adverse effects on dental health. Note that over time, habitual mouth breathing may lead to poor alignment of the teeth. An ear, nose and throat (ENT) specialist can treat problems with tonsils, adenoids and sinuses — common causes of mouth breathing.
FOREIGN OBJECT IN THE NOSE. It wouldn’t be the first time a child has stuck a pea or other small object up their nose â?? or their sibling’s nose — only to find that it won’t come back out. A foreign body in the nasal passage can cause infection and lead to bad breath.
- Tip: Don’t try to remove the object at home, as part of it may remain in the nasal passage. A medical professional will have the right equipment to dislodge the object more comfortably.
MEDICATION. Children who take antibiotics for a long time may develop a fungal infection (thrush) in the mouth. Other medications can cause bad breath due to the way they break down in the body.
- Tip: Call your pharmacist if you have a question about medications and bad breath.
MEDICAL CONDITION. Infections of the throat, sinus or tonsils can cause bad breath, as can more serious health conditions.
- Tip: If your child’s breath is unpleasant for an extended period of time, get it checked out by a health professional.
If you are concerned about your child’s breath, schedule a visit. We are happy to remind your child of proper brushing techniques and check for other problems that need to be addressed.

Like many other families, you may use formula instead of breast milk as a safe and healthy alternative to feed your infant. But, if you use a powdered form that you mix with water your child may be taking in more fluoride than they require.
Fluoride is a natural chemical that can strengthen tooth enamel and help prevent decay. After decades of study it's also been shown to pose no serious health risks. Because of fluoride's benefits and safety, many water utilities add tiny amounts to their drinking water supply.
But it can have one side effect called enamel fluorosis. If a child ingests too much fluoride during early development it can cause discoloring mottled spots or streaking in permanent teeth. Although it doesn't affect their health, the teeth can be unattractive and require cosmetic attention.
That's why it's best to keep fluoride consumption to a healthy minimum for children. That, however, is often easier said than done, since we can encounter hidden fluoride in a variety of places. Besides hygiene products and fluoridated drinking water, you may find fluoride in prepared juices and other beverages, bottled water or in foods processed with fluoridated water. There are no labeling requirements for fluoride, so you'll have to research to find out if a product contains fluoride.
There are, however, some things you can do to control your child's fluoride intake. First, know as much as you can about known sources your child may encounter like your water supply. You can find out if your utility adds fluoride and by how much by contacting them or visiting My Water's Fluoride online at https://nccd.cdc.gov/DOH_MWF/.
If you use fluoride toothpaste apply only a “smear” on the end of the brush for children under two and a pea-sized amount for older children. If you have fluoridated drinking water, consider breastfeeding your infant, use ready-to-feed formula or mix powdered formula with bottled water labeled “de-ionized,” “purified,” “demineralized” or “distilled.”
And, do feel free to discuss your concerns with us during your child's regular checkup. We'll help you adjust their diet, water intake and hygiene habits to be sure they're receiving the right amount they need for developing strong teeth — and no more.

At no other time in a person’s life will their teeth and mouth change as rapidly as it will between infancy and adolescence. In this short span an entire set of teeth will emerge and then gradually disappear as a second permanent set takes its place.
While the process may seem chaotic, there is a natural order to it. Knowing what to expect will help ease any undue concerns you may have about your child's experience.
The first primary teeth begin to appear (erupt) in sequence depending on their type. The first are usually the lower central incisors in the very front that erupt around 6-10 months, followed then by the rest of the incisors, first molars and canines (the “eye” teeth). The last to erupt are the primary second molars in the very back of the mouth just before age 3. A similar sequence occurs when they’re lost — the central incisors loosen and fall out around 6-7 years; the second molars are the last to go at 10-12 years.
A little “chaos” is normal — but only a little. Because of the tremendous changes in the mouth, primary teeth may appear to be going in every direction with noticeable spaces between front teeth. While this is usually not a great concern, it’s still possible future malocclusions (bad bites) may be developing. To monitor this effectively you should begin regular checkups around the child’s first birthday — our trained professional eye can determine if an issue has arisen that should be treated.
Protecting primary teeth from tooth decay is another high priority. There’s a temptation to discount the damage decay may do to these teeth because “they’re going to be lost anyway.” But besides their functional role, primary teeth also help guide the developing permanent teeth to erupt in the right position. Losing a primary tooth prematurely might then cause the permanent one to come in misaligned. Preventing tooth decay with daily oral hygiene and regular office visits and cleanings (with possible sealant protection) is a priority. And should decay occur, it’s equally important to preserve the tooth for as long as possible for the sake of the succeeding tooth.
Your child’s rapid dental development is part of their journey into adulthood. Keeping a watchful eye on the process and practicing good dental care will ensure this part of the journey is uneventful.

Some moviegoers have been known to crunch popcorn, bite their fingers or grab their neighbor’s hands during the intense scenes of a thriller. But for one fan, the on-screen action in the new superhero film Black Panther led to a different reaction.
Sophia Robb, an 18-year-old Californian, had to make an emergency visit to the orthodontic office because she snapped the steel wire on her retainer while watching a battle scene featuring her Hollywood crush, Michael B. Jordan. Her jaw-clenching mishap went viral and even prompted an unexpected reply from the actor himself!
Meanwhile, Sophia got her retainer fixed pronto—which was exactly the right thing to do. The retention phase is a very important part of orthodontic treatment: If you don’t wear a retainer, the beautiful new smile you’re enjoying could become crooked again. That’s because if the teeth are not held in their new positions, they will naturally begin to drift back into their former locations—and you may have to start treatment all over again…
While it’s much more common to lose a removable retainer than to damage one, it is possible for even sturdy retainers to wear out or break. This includes traditional plastic-and-wire types (also called Hawley retainers), clear plastic retainers that are molded to fit your teeth (sometimes called Essix retainers), and bonded retainers: the kind that consists of a wire that’s permanently attached to the back side of your teeth. So whichever kind you use, do what Sophia did if you feel that anything is amiss—have it looked at right away!
When Black Panther co-star Michael B. Jordan heard about the retainer mishap, he sent a message to the teen: “Since I feel partly responsible for breaking your retainers let me know if I can replace them.” His young fan was grateful for the offer—but even more thrilled to have a celebrity twitter follower.
