3WaystoCorrectaSmileWithMissingIncisors

In the classic holiday film, It's a Wonderful Life, George Bailey sees what life would be like if he'd never been born. In a variation on the theme, imagine your life if your teeth had never formed.

That's actually a reality for some—they're born without teeth, albeit usually only one or two. But even then, they're often more susceptible to problems with their bite, speech development and nutrition.

And if their missing teeth affects their appearance, their self-image could also take a hit. In particular, the maxillary lateral incisors on either side of the central incisors (those in the very front) can create an odd smile if missing.

Fortunately, we can correct the problem of missing lateral incisors with three possible solutions. The first is canine substitution, involving the pair of pointed teeth next in line to the missing incisors. In effect, we use orthodontic appliances like braces to move them toward the frontmost teeth and close the missing teeth gap.

It's a minimally invasive way to improve smile appearance. But because of their size and sharp edges, it's often necessary to alter the canines, perhaps even crown them. Some people may also need gum surgery to "blend" the gums with the repositioned teeth.

A second method is a fixed bridge, a series of fused crowns. Those in the middle replace the missing teeth, while those on the ends are bonded to the natural teeth on either side of the gap to support the bridge.

Bridges can function well for many years, but it does require permanently altering the supporting teeth for crowning. An alternative Maryland or bonded bridge doesn't require this alteration, but it's also less durable than a traditional bridge.

Finally, we could replace the missing teeth with dental implants, a titanium post imbedded into the jawbone with an attached life-like crown. An implant tooth can last for decades, and don't require alterations to other teeth. However, they're not suitable for younger patients who are still undergoing jaw development—a temporary restoration may thus be in order until the jaw matures.

Being born without certain teeth is something you can't do anything about. But you can change how it affects your appearance and life with one of these options for a new smile.

DentalImplantsCouldHelpPreserveBoneAfterToothLoss

Losing teeth can make it more difficult to eat, not to mention the effect it can have on your smile. But that could be just the beginning of your problems. Missing teeth can contribute to extensive bone loss within your jaws and face. Here's why.

Bone is like any other living tissue—cells develop, function and eventually die, and new cells take their place. Forces generated during chewing stimulate this new growth, helping the jawbone maintain its normal volume and density.

But you lose this stimulus when you lose teeth. This can cause a slowdown in bone cell regrowth that can eventually diminish bone volume. And it can happen relatively quickly: you could lose a quarter or more of jawbone width around a missing tooth within a year.

As this loss continues, especially in cases of multiple missing teeth, the bone can eventually erode to its base level. This loss of dental function can make chewing more difficult, place more pressure on the remaining teeth and adversely affect facial appearance. It could also prevent an implant restoration to replace missing teeth.

Dentures and other forms of dental restoration can replace missing teeth, but not the chewing stimulus. Dentures in particular will accelerate bone loss, because they can irritate the bony gum ridges they rest upon.

Dental implants, on the other hand, can slow or even stop bone loss. Implants consist of a metal post, typically made of titanium, imbedded into the jawbone at the site of the missing tooth with a life-like crown attached. Titanium also has a strong affinity with bone so that bone cells naturally grow and adhere to the implant's surface. This can produce enough growth to slow, stop or even reverse bone loss.

This effect may also work when implants are combined with other restorations, including dentures. These enhanced dentures no longer rest on the gums, but connect to implants. This adds support and takes the pressure off of the bony ridge, as well as contributes to better bone health.

If you've lost a tooth, it's important to either replace it promptly or have a bone graft installed to help forestall any bone loss in the interim. And when it's time to replace those missing teeth, dental implants could provide you not only a life-like solution, but a way to protect your bone health.

WhichImplantCrownAttachmentMethodisBestforYou

If you've decided on a dental implant to replace a missing tooth, you've made a great choice. Implants are a big favorite of both dentists and patients, not only for their life-likeness, but also their durability. Studies show that more than 95% of implants survive after ten years.

As you may know, single tooth implants are composed of two main parts: a metal post (usually titanium) imbedded in the jawbone; and a life-like crown affixed to the end of the post. But what you may not know is that there are two ways to attach the crown—either with screws or with dental cement.

Neither way is superior to the other—both have their own set of advantages and disadvantages. A cemented crown, for instance, usually looks more like a natural tooth than a screw-retained crown (more about that later) and dentists have more flexibility in making them look natural.

But cemented crowns require an additional piece of hardware called an abutment to better match it with the implant, something unnecessary with a screw-retained crown. Some people can also experience a reaction to the cement resulting in inflammation or even bone loss. And once installed, removing the crown later for repair or replacement is much more difficult than with a screw-retained crown.

Besides attaching directly to the implant, screw-retained crowns don't require cement and are more easily attached and removed. But the screw-hole can pose some aesthetic problems: Although it can be filled with a tooth-colored filling, the tooth's appearance isn't as ideal as a cemented crown.

So, which one is best for you? That will depend on the type and location of teeth being replaced, as well as your dentist's preferences. For instance, a more attractive cemented crown may be better for a visible front tooth, while a screw-retained crown might be a good choice for a back premolar or molar where appearance isn't as big a factor.

In the end, it's likely your dentist will discuss the pros and cons for each method as it pertains to your individual case. Whichever way your crown attaches, the end result will still be a life-like tooth that could last you for years to come.

CleaningAroundImplantsCrucialtoProtectingThemfromLoss

Unlike the natural tooth it replaces, a dental implant is impervious to decay. But don’t think that means you can relax your oral hygiene habits — even though the implant itself can’t be infected, the surrounding gum tissues and bone can. And if they’re not properly cared for you might eventually lose the implant.

In fact, implants may be more susceptible to problems from impacted food that becomes wedged between the gums and teeth than their natural counterparts. Natural teeth are connected to the jaw by way of a resilient, elastic tissue known as the periodontal ligament: the ligament resides in the space between the tooth root and the bone and attaches to both through tiny fibers. The bone and ligament are protected by an attachment of gum tissue that covers all of the surrounding bone and attaches to the root surface. The outer gum tissue surface is covered by a protein called keratin that makes it resistant to wear.

On the other hand, these periodontal ligament fibers don’t exist when implants are present as the implant is fastened directly to the bone. Because it doesn’t have this ligament attachment, and the gum tissues around can’t attach to the implant as with natural teeth, it may be more vulnerable to bacteria or trauma caused by food impaction. So, cleaning and caring for dental implants is just as important, if not more so than with natural teeth.

If the gums around an implant become infected and inflamed it could lead to peri-implantitis, a condition that can destroy the bone attachment between the implant and the bone. In other words, the loss of bone support can weaken the integration of the implant with the bone. As more and more attachment is lost, the implant can loosen and eventually be lost.

The best way to avoid this is with consistent daily hygiene and regular dental checkups. And, if you notice any signs of swelling or redness of the gums around an implant, contact us as soon as possible. The sooner we begin treatment to alleviate the infection, the less danger there will be of losing your implant.
