Let’s say you’re traveling to Italy to surprise your girlfriend, who is competing in an alpine ski race… and when you lower the scarf that’s covering your face, you reveal to the assembled paparazzi that one of your front teeth is missing. What will you do about this dental dilemma?

Sound far-fetched? It recently happened to one of the most recognized figures in sports — Tiger Woods. There’s still some uncertainty about exactly how this tooth was taken out: Was it a collision with a cameraman, as Woods’ agent reported… or did Woods already have some problems with the tooth, as others have speculated? We still don’t know for sure, but the big question is: What happens next?

Fortunately, contemporary dentistry offers several good solutions for the problem of missing teeth. Which one is best? It depends on each individual’s particular situation.

Let’s say that the visible part of the tooth (the crown) has been damaged by a dental trauma (such as a collision or a blow to the face), but the tooth still has healthy roots. In this case, it’s often possible to keep the roots and replace the tooth above the gum line with a crown restoration (also called a cap). Crowns are generally made to order in a dental lab, and are placed on a prepared tooth in a procedure that requires two office visits: one to prepare the tooth for restoration and to make a model of the mouth and the second to place the custom-manufactured crown and complete the restoration. However, in some cases, crowns can be made on special machinery right in the dental office, and placed during the same visit.

But what happens if the root isn’t viable — for example, if the tooth is deeply fractured, or completely knocked out and unable to be successfully re-implanted?

In that case, a dental implant is probably the best option for tooth replacement. An implant consists of a screw-like post of titanium metal that is inserted into the jawbone during a minor surgical procedure. Titanium has a unique property: It can fuse with living bone tissue, allowing it to act as a secure anchor for the replacement tooth system. The crown of the implant is similar to the one mentioned above, except that it’s made to attach to the titanium implant instead of the natural tooth.

Dental implants look, function and “feel” just like natural teeth — and with proper care, they can last a lifetime. Although they may be initially expensive, their quality and longevity makes them a good value over the long term. A less-costly alternative is traditional bridgework — but this method requires some dental work on the adjacent, healthy teeth; plus, it isn’t expected to last as long as an implant, and it may make the teeth more prone to problems down the road.

What will the acclaimed golfer do? No doubt Tiger’s dentist will help him make the right tooth-replacement decision.

If you have a gap in your grin — whatever the cause — contact us or schedule an appointment for a consultation, and find out which tooth-replacement system is right for you. You can learn more in the Dear Doctor magazine articles “Dental Implant Surgery” and “Crowns & Bridgework.”


ARetainer-LikeDevicecanPreservetheSpaceLeftbyaLostPrimaryTooth

Children losing their primary (“baby”) teeth is both natural and necessary. So, is it really that much of a concern if they lose one early?

The answer is yes — premature primary tooth loss could have long-term consequences for the permanent teeth as they develop within the jaw before eruption. Primary teeth play a crucial role in this development: as the permanent teeth form and grow the primary teeth serve as placeholders until they’re ready to erupt. A natural process then takes place in which the primary tooth’s roots dissolve (resorb) to allow them to fall out. Once they’re out of the way, the permanent teeth can then erupt.

If, however, they’re lost before the permanent teeth are ready, it leaves a space in the child’s bite. The dynamic mechanism between teeth and the periodontal ligament causes adjacent teeth to move or “drift” into the space. This can crowd out the permanent tooth intended for the space, causing it to come in improperly forming a malocclusion (bad bite), or it may become impacted and remain partially or fully below the surface of the gums.

This poor dental development could lead to extensive orthodontic treatment later in life, which is why we seek to preserve even decayed primary teeth for their entire natural lifespan. If the tooth is lost, however, we need to take action to preserve the space for the permanent tooth and avoid costly treatment later.

This usually calls for a “space maintenance” appliance — a type of orthodontic “retainer” — worn by the child to prevent other teeth from drifting into the space. Designed by your orthodontist, the appliance can also perform a cosmetic and social function by causing the space to appear unnoticeable.

Maintaining that space requires monitoring — especially by an orthodontist — and continued dental hygiene and care both at home and at the dentist’s office. The extra care preserving the space caused by premature tooth loss will help to ensure your child’s dental structure develops properly and their future smile will be an attractive one.

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!
