EdenSherandtheLostRetainer

Fans of the primetime TV show The Middle were delighted to see that high school senior Sue, played by Eden Sher, finally got her braces off at the start of Season 6. But since this popular sitcom wouldn’t be complete without some slapstick comedy, this happy event is not without its trials and tribulations: The episode ends with Sue’s whole family diving into a dumpster in search of the teen’s lost retainer. Sue finds it in the garbage and immediately pops it in her mouth. But wait — it doesn’t fit, it’s not even hers!

If you think this scenario is far-fetched, guess again. OK, maybe the part about Sue not washing the retainer upon reclaiming it was just a gag (literally and figuratively), but lost retainers are all too common. Unfortunately, they’re also expensive to replace — so they need to be handled with care. What’s the best way to do that? Retainers should be brushed daily with a soft toothbrush and liquid soap (dish soap works well), and then placed immediately back in your mouth or into the case that came with the retainer. When you are eating a meal at a restaurant, do not wrap your retainer in a napkin and leave it on the table — this is a great way to lose it! Instead, take the case with you, and keep the retainer in it while you’re eating. When you get home, brush your teeth and then put the retainer back in your mouth.

If you do lose your retainer though, let us know right away. Retention is the last step of your orthodontic treatment, and it’s extremely important. You’ve worked hard to get a beautiful smile, and no one wants to see that effort wasted. Yet if you neglect to wear your retainer as instructed, your teeth are likely to shift out of position. Why does this happen?

As you’ve seen firsthand, teeth aren’t rigidly fixed in the jaw — they can be moved in response to light and continuous force. That’s what orthodontic appliances do: apply the right amount of force in a carefully controlled manner. But there are other forces at work on your teeth that can move them in less predictable ways. For example, normal biting and chewing can, over time, cause your teeth to shift position. To get teeth to stay where they’ve been moved orthodontically, new bone needs to form around them and anchor them where they are. That will happen over time, but only if they are held in place with a retainer. That’s why it is so important to wear yours as directed — and notify us immediately if it gets lost.

And if ever you do have to dig your retainer out of a dumpster… be sure to wash it before putting in in your mouth!

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.
