ReplacingaKnocked-OutToothQuicklyIncreasesitsSurvivalChances

Mouth injuries in children and teens are more common than you might think: about one out of three boys and one out of four girls will have experienced an injury before they graduate from high school. Besides contact sports, other types of accidents like car crashes or falls are high on the cause list.

Although most dental injuries aren’t considered true emergencies, there are a few where prompt action may mean the difference between ultimately saving or losing a tooth. One such situation is a knocked out tooth.

In the event of a knocked out (or avulsed) tooth, your primary goal is to place the tooth back into the empty socket as quickly as possible. Teeth that have been out of the mouth for less than five minutes have the best chance of reattachment and survival. The first step is to quickly locate the missing tooth.

Once you’ve found it, use only cold, clean water run or poured over the tooth to carefully clean off dirt or debris (no soaps or cleansers). You should also avoid touching the tooth root or scrubbing any part of it. After cleaning it of debris, gently place the tooth back in its socket, then immediately contact us or visit an emergency room. While you’re en route to our office the patient should carefully hold the tooth in place. If the tooth can’t be immediately placed into the socket (the patient is unconscious, for example), then you should place the tooth in a clean container and keep it moist with cold milk, a sterile saline solution or even the patient’s saliva.

Taking these steps increases the chances of a successful re-implantation, although the injury may ultimately affect the tooth’s lifespan. Replanted teeth can suffer from root resorption (where the root tissue dissolves) or a process known as ankylosis in which the tooth fuses directly to the jawbone with no healthy periodontal ligament in between. Either of these conditions can lead to tooth loss.

Still, it’s worthwhile to try to save the tooth, even if for a few more years. Those extra years can help you prepare for a future restoration.

AmericasDentistsGotTalent-forFixingDamagedorMissingTeeth

A recent episode of “America’s Got Talent” featured an engaging 93-year-old strongman called The Mighty Atom Jr. The mature muscleman’s stunt: moving a full-sized car (laden with his octogenarian “kid brother,” his brother’s wife, plus Atom’s “lady friend”) using just his teeth. Grinning for host Howie Mandel, Atom proudly told the TV audience that his teeth were all his own; then he grasped a leather strap in his mouth, and successfully pulled the car from a standstill.

We’re pleased to see that the Atom has kept his natural teeth in good shape: He must have found time for brushing and flossing in between stunts. Needless to say, his “talent” isn’t one we’d recommend trying at home. But aside from pulling vehicles, teeth can also be chipped or fractured by more mundane (yet still risky) activities — playing sports, nibbling on pencils, or biting too hard on ice. What can you do if that happens to your teeth?

Fortunately, we have a number of ways to repair cracked or chipped teeth. One of the easiest and fastest is cosmetic bonding with tooth-colored resins. Bonding can be used to fill in small chips, cracks and discolorations in the teeth. The bonding material is a high-tech mixture of plastic and glass components that’s extremely lifelike, and can last for several years. Plus, it’s a procedure that can be done right in the office, with minimal preparation or discomfort. However, it may not be suitable for larger chips, and it isn’t the longest-lasting type of restoration.

When more of the tooth structure is missing, a crown (or cap) might be needed to restore the tooth’s appearance and function. This involves creating a replacement for the entire visible part of the tooth in a dental lab — or in some cases, right in the office. It typically involves making a model of the damaged tooth and its neighbors, then fabricating a replica, which will fit perfectly into the bite. Finally, the replacement crown is permanently cemented to the damaged tooth. A crown replacement can last for many years if the tooth’s roots are in good shape. But what if the roots have been dislodged?

In some cases it’s possible to re-implant a tooth that has been knocked out — especially if it has been carefully preserved, and receives immediate professional attention. But if a tooth can’t be saved (due to a deeply fractured root, for example) a dental implant offers today’s best option for tooth replacement. This procedure has a success rate of over 95 percent, and gives you a natural looking replacement tooth that can last for the rest of your life.

So what have we learned? If you take care of your teeth, like strongman Atom, they can last a long time — but if you need to move your car, go get the keys.
