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.

If you've suddenly noticed your smile looking more “toothy,” you may have a problem with your gums. They may have lost their normal attachment to your tooth and begun to shrink back — or recede.
Millions of people have some form of gum recession. The most common cause is periodontal (gum) disease, but it's not the only one. You may be more susceptible to gum recession because of heredity — you have thin gum tissues passed down to you from your parents. You may also be brushing too hard and too often and have damaged your gums.
Healthy gums play an important role in dental health. The crown, the tooth's visible part, is covered with a hard, protective shell called enamel. As the enamel ends near where the root begins, the gums take over, forming a tight band around the tooth to protect the roots from bacteria and acid.
Receding gums expose these areas of the tooth meant to be covered. This can lead to another tell-tale sign — tooth sensitivity. You begin to notice pain and discomfort while you consume hot or cold foods. And because it leaves your teeth and gums looking much less attractive, it can affect your confidence to smile.
Fortunately, though, we can help restore receded gums. If you have gum disease, it's imperative we treat it as early as possible. We do this by removing plaque, a thin film of bacteria and food particles that triggers the infection. We use special techniques and hand instruments to remove plaque and calculus (hardened plaque deposits) from all tooth surfaces including along the roots.
Gum disease treatment can help stop and even reverse gum recession. In some cases, though, the recession may have advanced too far. If so, we may need to consider surgically grafting donor tissue to the recessed areas. Depending on the site and extent of recession, this can be a very involved procedure requiring microscopic techniques.
The best approach, though, is to take care of your gums now. Daily brushing and flossing removes harmful plaque; regular dental visits take cleaning a step further and also give us an opportunity to detect disease early. By looking out for your gums now you might be able to avoid gum recession in the future.
