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.

While many people still consider dental implants the "new kids on the block" in dental restoration, they're now in their fourth decade of use. And since their inception implant technology has continued to improve and revolutionize how we replace missing teeth.
Implants are a different "species" compared to other restoration methods. To be precise, an implant is a tooth root replacement—usually a titanium metal post imbedded directly into the jaw bone. Titanium is not only a biocompatible metal, but bone cells naturally grow on its surface to create a strong and durable hold. It's this secure hold that's most responsible for implants' high long-term success rate.
But we should also credit some of this success to the steady stream of advances over the years in implant construction and supporting technologies. For one thing, we're now more accurate and precise with implant placement thanks to advances in computer tomography (CT) and cone beam CT (CBCT) scanning.
These digital processes merge a series of images taken by a special camera to form a three-dimensional model of the jaw. We can manipulate this model on a computer monitor to view it from different vantage points. It can help us locate and avoid anatomical structures like nerves and sinuses when determining where to place a future implant. CT and CBCT are especially useful when there's a concern about adequate available bone, a necessity for stable implants.
Technology has also improved how we create surgical guides, often used during implant surgery to obtain the most accurate results. Surgical guides are custom-made devices that fit over the teeth with the drilling locations for the implants marked on them. Recent advances in 3-D printing have made these guides even more accurate so that they fit more securely in the mouth. This greater stability increases their accuracy during the drilling sequence during surgery.
These and other advances are helping ensure every implant is a success story. The end result is both a functional restoration and a beautiful smile.

Whether you live in the snow belt or the sunny south, the winter season often means a change in the weather. In many places, the sun isn't as strong and cooler temperatures bring relief from the summer's heat. Yet even though it may be chillier outside, your body's need for hydration is the same as it was in the summer—and a lack of proper hydration can be bad news for your oral hygiene.
Everyone knows we need to drink plenty of water every day to stay healthy. It's important for good oral hygiene because water is the major component of saliva, which fights bacteria and helps neutralize the acids that cause tooth decay. Water also keeps the soft tissues of the mouth moist and healthy, and helps fight bad breath. In many communities tap water is fluoridated, which offers proven protection against cavities.
But in the middle of winter, fewer people carry around bottles of cold water for refreshment—and that's a shame, because we need it just as much! While indoor (and outdoor) air is often drier in winter, your body continues to lose water in the same ways. And if you keep up a healthy exercise routine (like jogging, snow sports or backyard fun and games), you still need plenty of hydration. An ice-cold glass of water may not be as appealing in January as in July…but it's just as important.
Of course, the water you drink doesn't have to be freezing cold to do its job. Hot tea (especially herbal tea) can be a healthy option for wintertime hydration. So is plain water without ice. Fruits and vegetables also contain lots of water, plus vitamins, fiber, and many more substances that are good for your body.
But there are some drinks you should avoid—or at least take in moderation. Regularly drinking coffee and tea can stain your teeth, and excessive caffeine may have negative health effects. Consuming alcoholic beverages can cause dry mouth, and may increase the risk of oral cancers. And, of course, drinks that contain sugar (including soda, some juices, and many coffee and hot chocolate beverages) are linked not only to tooth decay, but to other health problems as well.
And whatever the season, don't forget to come in to the dental office for regular checkups and cleanings. We can remove the sticky tartar that clings to your teeth and may cause tooth decay and other problems. We will also perform a complete dental exam, evaluate your oral health and help resolve small problems before they turn into big headaches (or toothaches). Working together, we can help you enjoy the benefits of good oral hygiene all though the year.
