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.

The National Safety Council has designated June as National Safety Month. A key component of staying safe is being prepared for emergencies, and this includes dental emergencies. Would you know what to do if you suffered any of the following dental mishaps?
Chipped tooth: One common dental injury is a chipped tooth. If this happens to you, save the missing chip if possible because we may be able to bond it back onto the tooth—but don’t be tempted to glue the chip back on by yourself! However, even without the missing chip, the tooth can most often be repaired with bonding material.
Cracked tooth: If you crack a tooth, rinse your mouth with warm water. If it is bleeding, hold a clean washcloth or gauze to the area until the bleeding stops, but don’t wiggle the tooth around or bite down hard. Keep in mind that the sooner your tooth is repaired, the better. Depending on how bad the crack is, if the tooth can be treated, it will most likely continue to function pain-free for years to come.
Displaced (“luxated”) tooth: If an injury causes your tooth to become loose, shoves it sideways or pushes it into or out of its socket, don’t try to force the tooth back into position on your own. Instead, call the dental office right away and leave it to us to bring the tooth back into its proper place and determine the extent of the injury.
Knocked out tooth: If a permanent tooth is knocked out of your mouth, pick it up without touching the root and rinse it off with cold water, but do not scrub. For the best chance of saving the tooth, place it firmly back in its socket within five minutes and hold it in position for a few minutes. If this is not possible, keep the tooth between your cheek and gum or in a glass of cold milk so that it doesn’t dry out. Call the dental office immediately.
If a baby tooth is knocked out, there is no need to place it back in the socket since baby teeth are not reattached. However, it is still important to have us examine the injury.
Being prepared for dental emergencies can help save a tooth as well as avoid more costly dental treatment down the road. But no matter what type of dental injury you have, it is important to come in for a consultation as the injury may extend beyond the part of the tooth that is visible. With today’s materials and technology, there’s a very good chance your smile can look as good as before—and often even better!

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.
