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.

You can't separate your oral health from your overall health. What's beneficial for your body in general is usually beneficial for your teeth and gums.
Take the foods you eat: good nutrition is essential to general health and well-being. But the same foods that keep the rest of your body healthy often do the same for your mouth—and those that are not so good for the rest of you are usually not good for your teeth and gums either.
Here are 4 different types of foods that positively impact both mouth and body.
Cheese and dairy. Dairy products are rich in calcium, essential for strengthening both your bones and your teeth. Cheese helps stimulate saliva and protects against calcium loss. Cow's milk contains minerals and proteins both your body and mouth needs. It also contains lactose, a less acidic sugar that doesn't contribute to tooth decay.
Plant foods. Vegetables and fruit are loaded with vitamins and nutrients that keep the body functioning normally. They also contain fiber: Not only is this good for your digestive system, it requires chewing to break it down in the mouth, which stimulates saliva. A good flow of saliva helps prevent your mouth from becoming too acidic and thus more prone to dental disease.
Black and green teas. A nice cup of hot tea isn't just soothing—it's rich in antioxidants that help fight disease in the body (and the mouth). Black tea also contains fluoride, which has been proven to strengthen enamel against acid attack.
Chocolate. There's both good and bad news about this perennial favorite. The good news is the polyphenolic compounds (a kind of antioxidant) in unrefined cocoa can protect against disease including tooth decay. The bad news is most processed chocolate is loaded with added sugar—not the healthiest substance for your body, and definitely not for your teeth. Try then to incorporate small amounts of chocolate in your diet, the lower the sugar content the better.
Eating nutritiously helps your body stay healthy and disease-free. And coupled with daily hygiene and regular dental visits, it's one of the best things you can do for your teeth and gums.

Boston Bruins defenseman Zdeno Chara had a rough Stanley Cup final against the St. Louis Blues this past June. Not only did the Bruins ultimately lose the championship, but Chara took a deflected puck shot to the face in Game Four that broke his jaw.
With the NHL season now over, the 42-year-old Bruins captain continues to mend from his injury that required extensive treatment. His experience highlights how jaw fractures and related dental damage are an unfortunate hazard in hockey—not only for pros like Chara, but also for an estimated half million U.S. amateurs, many in youth leagues.
Ice hockey isn't the only sport with this injury potential: Basketball, football (now gearing up with summer training) and even baseball players are also at risk. That's why appropriate protective gear like helmets and face shields are key to preventing injury.
For any contact sport, that protection should also include a mouthguard to absorb hard contact forces that could damage the mouth, teeth and gums. The best guards (and the most comfortable fit) are custom-made by a dentist based on impressions made of the individual's mouth.
But even with adequate protection, an injury can still happen. Here's what you should do if your child has an injury to their jaw, mouth or teeth.
Recognize signs of a broken jaw. A broken jaw can result in severe pain, swelling, difficulty speaking, numbness in the chin or lower lip or the teeth not seeming to fit together properly. You may also notice bleeding in the mouth, as well as bruising under the tongue or a cut in the ear canal resulting from jawbone movement during the fracture. Get immediate medical attention if you notice any of these signs.
Take quick action for a knocked-out tooth. A tooth knocked completely out of its socket is a severe dental injury. But you may be able to ultimately save the tooth by promptly taking the following steps: (1) find the tooth and pick it up without touching the root end, (2) rinse it off, (3) place it back in its socket with firm pressure, and (4) see a dentist as soon as possible.
Seek dental care. Besides the injuries already mentioned, you should also see a dentist for any moderate to severe trauma to the mouth, teeth and gums. Leading the list: any injury that results in tooth chipping, looseness or movement out of alignment.
Even a top athlete like Zdeno Chara isn't immune to injury. Take steps then to protect your amateur athlete from a dental or facial injury.
