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.

Find out how this treatment could prevent teeth from shifting out of alignment.
A child should begin losing their baby teeth around the age of 6 years old; however, if your child is losing their baby teeth to cavities or other issues, then there may be a concern that teeth might shift out of alignment. To combat this, our Amherst, NH, pediatric dentists Dr. James McAveeney and Dr. Andrew Cheifetz may recommend placing a space maintainer.
What is a space maintainer?
If your baby’s molars aren’t present (often due to a congenital abnormality) or if your child has lost teeth a little too young then a space maintainer may be the best approach for preventing teeth from shifting out of place. If these teeth shift out of place they can also affect how adult teeth come in, causing further misalignments or other issues.
A space maintainer will not be necessary if the first six front teeth have fallen out prematurely, as the sole purpose of a space maintainer is to hold the six-year molars in their proper position and to provide a space for the canines and other teeth to come through.
The most common type of space maintainer is a fixed one, which means that the wearer can’t remove the appliance. The appliance will be cemented into place by our Amherst, NH, pediatric dentist to make sure that it is effective at keeping your child’s developing smile in alignment as permanent teeth continue to come in.
What are the benefits of getting a space maintainer for my child?
The most obvious benefit, which we already touched upon, is the fact that a space maintainer will create a holding spot for teeth to erupt, preventing them from shifting out of alignment or causing problems for adult teeth that are trying to come in. For example, a space maintainer is perfect for preventing the movement of premolars (also known as bicuspids) and permanent molars while also creating the ample space for permanent teeth to erupt.
Is your child losing teeth a little earlier than they should? Do you want to know if a space maintainer may preserve their smile as it continues to develop? If so, it’s the perfect time to call our office to learn more about the pediatric dental services we offer here in Amherst, NH. Turn to Children's Dental Center of New Hampshire today.
Fluoride has been proven to strengthen tooth enamel against decay. That’s why it’s not only added to toothpaste and other dental products, but also to drinking water — in nearly three-quarters of U.S. water systems.
While research has eased most serious health questions about fluoride, there remains one moderate concern. Too much fluoride over time, especially in infants and young children, could lead to “enamel fluorosis,” an excess of fluoride in the tooth structure that can cause spotting or streaking in the enamel. While often barely noticeable, some cases of fluorosis can produce dark staining and a pitted appearance. Although not a symptom of disease, fluorosis can create a long-term cosmetic concern for the person.
To minimize its occurrence, children under the age of 9 shouldn’t regularly ingest fluoride above of the recommended level of 0.70 ppm (parts per million). In practical terms, you as a parent should monitor two primary sources of fluoride intake: toothpaste and drinking water.
Young children tend to swallow toothpaste rather than spit it out after brushing, which could result in too much fluoride ingestion if the amount is too great. The American Academy of Pediatric Dentistry therefore recommends a small “smear” of toothpaste for children under two, and a pea-sized amount for children up to age six. Brushing should also be limited to no more than two times a day.
Your child or infant could also take in too much fluoride through fluoridated drinking water, especially if you’re using it to mix infant formula. You should first find out the fluoride levels in your local water system by contacting the utility or the health department. If your system is part of the U.S. Centers for Disease Control and Prevention’s (CDC) “My Water’s Fluoride” program, you may be able to access that information on line at //apps.nccd.cdc.gov/MWF/Index.asp.
If the risk for developing fluorosis in your area is high, you can minimize your infant’s intake with a few recommendations: breastfeed rather than use formula; use “ready-to-feed” formula that doesn’t need mixing and contains lower fluoride levels; and use bottled water specifically labeled “de-ionized,” “purified,” “de-mineralized,” or “distilled.”
Fluoride can be a wonderful adjunct to dental care in reducing risk for tooth decay. Keeping an eye on how much fluoride your child takes in can also minimize the chance of future appearance problems.

There are a lot of things we do without much conscious thought — habits we've developed over time. Some habits help streamline our lives for the good; others, though, hold us back or even harm us. A lot of these habits, both good and bad, form during our childhood years.
That's why it's important for you to guide your children into forming good habits. The goal is that when they're adults they'll “own” these habits, and their life will be healthier and happier because of them.
One particular area of habit-forming focus is dental care. It's essential your children develop good habits caring for their teeth and gums. The most important is a daily routine of brushing and flossing.
Brushing and flossing has one primary aim: to remove bacterial plaque, a thin film of food particles that builds up on tooth surfaces. Bacteria in plaque are the main cause for two potentially devastating diseases, tooth decay and periodontal (gum) disease. Allowing plaque to build up over just a few days can trigger an infection that inflames the gums or softens enamel leading to tooth decay. Left untreated these diseases can ultimately cause tooth and bone loss.
A daily habit of brushing and flossing, along with semi-annual professional cleanings, can drastically reduce a person's risk for these diseases. It's best to instill these habits and their importance as soon as your child's teeth begin to erupt in the mouth.
In the beginning, you'll be performing the habit for them: for children two and younger use a slight smear of toothpaste on the brush. As they get older, you can increase it to pea size. Eventually you'll want to help them learn to brush on their own. In this case, modeling the behavior — both of you brushing your teeth together — will have the biggest impact and help them see how important the habit really is.
Before you know it, brushing and flossing will become second nature, a habit they'll begin doing on their own without being told. Once instilled, it'll be a habit they'll practice long after they leave your care — and one they'll hopefully pass on to their own children.
