One of the biggest concerns we hear from parents is about their child's thumb sucking habit. Our advice: if they're under age 4, there's no need for concern — yet. If they're older, though, you should be concerned about the possible effect on their bite.
Thumb sucking is a universal habit among infants and toddlers and is related to their swallowing pattern during feeding. As they swallow, their tongue thrusts forward to create a seal with the lips around the breast or a bottle nipple. Many pediatricians believe thumb sucking replicates nursing and so has a comforting effect on infants.
Around age 4, though, this swallowing pattern begins to change to accommodate solid food. The tongue now begins to rest at the back of the top front teeth during swallowing (try swallowing now and you'll see). For most children, their thumb sucking habit also fades during this time and eventually stops.
But for whatever reason, some children don't stop. As the habit persists, the tongue continues to thrust forward rather than toward the back of the top front teeth. Over time this can place undue pressure on both upper and lower front teeth and contribute to the development of an open bite, a slight gap between the upper and lower teeth when the jaws are shut.
While late childhood thumb sucking isn't the only cause for an open bite (abnormal bone growth in one jaw is another), the habit is still a prominent factor. That's why it's important that you start encouraging your child to stop thumb sucking around age 3 and no later than 4. This is best accomplished with positive reinforcement like rewards or praise.
If they've continued the habit a few years after they should have stopped, we may also need to check to see if their swallowing mechanism has become stunted. If so, we may need to use certain exercises to retrain their tongue to take the proper position during swallowing.
While you shouldn't panic, it's important to take action to stop thumb sucking before it becomes a long-term problem. A positive, proactive approach will help avoid costly orthodontic problems later in their lives.

In real life he was a hard-charging basketball player through high school and college. In TV and the movies, he has gone head-to-head with serial killers, assorted bad guys… even mysterious paranormal forces. So would you believe that David Duchovny, who played Agent Fox Mulder in The X-Files and starred in countless other large and small-screen productions, lost his front teeth… in an elevator accident?
“I was running for the elevator at my high school when the door shut on my arm,” he explained. “The next thing I knew, I was waking up in the hospital. I had fainted, fallen on my face, and knocked out my two front teeth.” Looking at Duchovny now, you’d never know his front teeth weren’t natural. But that’s not “movie magic” — it’s the art and science of modern dentistry.
How do dentists go about replacing lost teeth with natural-looking prosthetics? Today, there are two widely used tooth replacement procedures: dental implants and bridgework. When a natural tooth can’t be saved — due to advanced decay, periodontal disease, or an accident like Duchovny’s — these methods offer good looking, fully functional replacements. So what’s the difference between the two? Essentially, it’s a matter of how the replacement teeth are supported.
With state-of-the-art dental implants, support for the replacement tooth (or teeth) comes from small titanium inserts, which are implanted directly into the bone of the jaw. In time these become fused with the bone itself, providing a solid anchorage. What’s more, they actually help prevent the bone loss that naturally occurs after tooth loss. The crowns — lifelike replacements for the visible part of the tooth — are securely attached to the implants via special connectors called abutments.
In traditional bridgework, the existing natural teeth on either side of a gap are used to support the replacement crowns that “bridge” the gap. Here’s how it works: A one-piece unit is custom-fabricated, consisting of prosthetic crowns to replace missing teeth, plus caps to cover the adjacent (abutment) teeth on each side. Those abutment teeth must be shaped so the caps can fit over them; this is done by carefully removing some of the outer tooth material. Then the whole bridge unit is securely cemented in place.
While both systems have been used successfully for decades, bridgework is now being gradually supplanted by implants. That’s because dental implants don’t have any negative impact on nearby healthy teeth, while bridgework requires that abutment teeth be shaped for crowns, and puts additional stresses on them. Dental implants also generally last far longer than bridges — the rest of your life, if given proper care. However, they are initially more expensive (though they may prove more economical in the long run), and not everyone is a candidate for the minor surgery they require.

Cavities and gum disease do not have to become commonplace. Stop these issues in their tracks.
There are so many issues that can affect the appearance and health of your smile. Luckily, you have a lot of say when it comes to your oral health. Our Burlington and Jericho, VT, dentists, Dr. Paul Dunkling and Dr. Greg Penney, proffer up some ways to keep your teeth and gums in great shape.
Brush and Floss
Yes, you probably know that brushing and flossing are necessary to keeping your teeth and gums healthy and safe from infection, decay or other issues. Of course, despite knowing this so many people decide not to brush or floss as often as they should. Brushing twice a day will prevent food from sitting on teeth all day long (brushing between meals is also highly encouraged) and flossing right before bed will ensure that food and plaque is removed from between teeth.
Consume Healthy Foods
While most people know that eating healthy is important for maintaining good general health it is also important for giving your teeth, gums and jawbone the nutrients they need. By staying away from carb-rich foods that contain sugars and starches such as cereals, soda, cakes, candy and bread and replacing these foods with healthy alternatives (fruits and vegetables are your friends!) you will reduce your chances of tooth decay.
While public drinking water in many regions contain the proper amount of fluoride that you need it’s never a bad idea to also used fluoridated toothpaste. Why? Fluoride is one element that is important for maintaining strong tooth enamel. When sugar and starches are turned into acid this acid can eat away at enamel and weaken it. Fluoride works to restrengthen it.

Since the discovery a century ago of its beneficial effect on tooth enamel, fluoride has become an important part of tooth decay prevention. It's routinely added to toothpaste and other hygiene products, and many water utilities add minute amounts of it to their drinking water supplies. Although there have been questions about its safety, multiple studies over the last few decades have eased those concerns.
Children especially benefit from fluoride during their teeth's developing years. Some children are at high risk for decay, especially an aggressive form known as Early Childhood Caries (ECC). ECC can destroy primary (baby) teeth and cause children to lose them prematurely. This can have an adverse effect on incoming permanent teeth, causing them to erupt in the wrong positions creating a bad bite (malocclusion).
For children at high risk for decay, dentists often recommend applying topical fluoride directly to the teeth as added protection against disease. These concentrations of fluoride are much higher than in toothpaste and remain on the teeth for much longer. Topical applications have been shown not only to reduce the risk of new cavities, but to also stop and reverse early decay.
Children usually receive these applications during an office visit after their regular dental cleaning. There are three different ways to apply it: gel, foam or varnish. To prevent swallowing some of the solution (which could induce vomiting, headache or stomach pain) the dentist will often insert a tray similar to a mouth guard to catch any excess solution. Varnishes and a few gels are actually painted on the teeth.
The American Dental Association has intensely studied the use of topical fluoride and found its application can result in substantial decreases in cavities and lost teeth. They've concluded this benefit far outweighs the side effects from ingesting the solution in children six years and older. With proper precautions and waiting to eat for thirty minutes after an application, the possibility of ingestion can be reduced even further.
While topical fluoride can be effective, it's only one part of a good dental care strategy for your child. Consistent daily brushing and flossing, a nutritious diet low in added sugar, and regular dental visits still remain the backbone of preventive care.
