RemovingOneorMoreTeethCouldImproveOrthodonticOutcomes

Moving teeth through orthodontics may involve more than simply wearing braces. There are many bite conditions that require extra measures before, during or after traditional orthodontic treatment to improve the outcome.

One such measure is extracting one or more teeth. Whether or not we should will depend on the causes behind a patient's poor dental bite.

Here, then, are 4 situations where tooth extraction before orthodontics might be necessary.

Crowding. This happens when the jaw isn't large enough to accommodate all the teeth coming in. As a result, later erupting teeth could erupt out of position. We can often prevent this in younger children with space maintainers or a palatal expander, a device which helps widen the jaw. Where crowding has already occurred, though, it may be necessary to remove selected teeth first to open up jaw space for desired tooth movement.

Impacted teeth. Sometimes an incoming tooth becomes blocked and remains partially or fully submerged beneath the gums. Special orthodontic hardware can often be used to pull an impacted tooth down where it should be, but not always. It may be better to remove the impacted tooth completely, as well as its matching tooth on the other side of the jaw to maintain smile balance before orthodontically correcting the bite.

Front teeth protrusion. This bite problem involves front teeth that stick out at a more horizontal angle. Orthodontics can return the teeth to their proper alignment, but other teeth may be blocking that movement. To open up space for movement, it may be necessary to remove one or more of these obstructing teeth.

Congenitally missing teeth. The absence of permanent teeth that failed to develop can disrupt dental appearance and function, especially if they're near the front of the mouth. They're often replaced with a dental implant or other type of restoration. If only one tooth is missing, though, another option would be to remove the similar tooth on the other side of the jaw, and then close any resulting gaps with braces.

Extracting teeth in these and other situations can help improve the chances of a successful orthodontic outcome. The key is to accurately assess the bite condition and plan accordingly.

CrazyLittleThingCalledHyperdontia

The movie Bohemian Rhapsody celebrates the iconic rock band Queen and its legendary lead vocalist, Freddie Mercury. But when we see pictures of the flamboyant singer, many fans both old and new may wonder—what made Freddie’s toothy smile look the way it did? Here’s the answer: The singer was born with four extra teeth at the back of his mouth, which caused his front teeth to be pushed forward, giving him a noticeable overbite.

The presence of extra teeth—more than 20 primary (baby) teeth or 32 adult teeth—is a relatively rare condition called hyperdontia. Sometimes this condition causes no trouble, and an extra tooth (or two) isn’t even recognized until the person has an oral examination. In other situations, hyperdontia can create problems in the mouth such as crowding, malocclusion (bad bite) and periodontal disease. That’s when treatment may be recommended.

Exactly what kind of treatment is needed? There’s a different answer for each individual, but in many cases the problem can be successfully resolved with tooth extraction (removal) and orthodontic treatment (such as braces).¬†Some people may be concerned about having teeth removed, whether it’s for this problem or another issue. But in skilled hands, this procedure is routine and relatively painless.

Teeth aren’t set rigidly in the jawbone like posts in cement—they are actually held in place dynamically by a fibrous membrane called the periodontal ligament. With careful manipulation of the tooth, these fibers can be dislodged and the tooth can be easily extracted. Of course, you won’t feel this happening because extraction is done under anesthesia (often via a numbing shot). In addition, you may be given a sedative or anti-anxiety medication to help you relax during the procedure.

After extraction, some bone grafting material may be placed in the tooth socket and gauze may be applied to control bleeding; sutures (stitches) are sometimes used as well. You’ll receive instructions on medication and post-extraction care before you go home. While you will probably feel discomfort in the area right after the procedure, in a week or so the healing process will be well underway.

Sometimes, dental problems like hyperdontia need immediate treatment because they can negatively affect your overall health; at other times, the issue may be mainly cosmetic. Freddie Mercury declined treatment because he was afraid dental work might interfere with his vocal range. But the decision to change the way your smile looks is up to you; after an examination, we can help you determine what treatment options are appropriate for your own situation.

RootCanalsareaSafeWaytoSaveTeeth

Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.

Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.

So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.

As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.

In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.

Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

DoYouHaveAdequateBonetoSupportanImplant

Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.

Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.

Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.

Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.

However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.

Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. ¬†After several months, we may have enough regenerated bone to support an implant.

If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.

YouMayNeedOrthodonticsBeforeReplacingaMissingTooth

Sometimes you need only a single solution to improve your smile: teeth whitening to brighten stained teeth; porcelain veneers or crowns to mask dental flaws; or a life-like dental implant to replace a missing tooth. But not all dental situations are that simple and sometimes require a combination of treatments.

A case in point: restoring a missing tooth within a poor bite. The absent tooth itself may be the cause of the bite problem if it’s been missing for some time: The nearby teeth tend to move or “drift” into the empty space, leaving no room for implant placement.

When this happens, you’ll first need orthodontic treatment to correct the bite problem. Not only will this open the space for the implant, it also comes with its own benefits. It obviously improves your smile appearance—but straighter teeth are also easier to keep clean of bacterial plaque, which reduces your disease risk. You may also experience better digestion after your teeth are properly aligned and able to function as they should during eating.

The traditional way to improve a bite is through metal braces. But there are some downsides: For one, braces can make it difficult to keep teeth adequately clean, making wearers more susceptible to tooth decay and gum disease. Braces are also quite visible and can detract from a person’s appearance (even more so if a missing tooth is involved).

Unless your situation requires braces, you can choose clear aligners as an alternative. These clear, computer-generated plastic trays are worn in sequence to gradually move teeth to their desired positions. Unlike braces, you can remove aligners for eating, cleaning or rare special occasions. And, they’re barely noticeable to others.

If you also have a missing tooth, you can have a temporary prosthetic (“false”) tooth built into your aligner trays. In this way you can still enhance your smile while undergoing aligner treatment.

Once your bite has been corrected, we can then proceed with restoring your missing tooth permanently with a dental implant. Although orthodontics adds to the time and expense of restoration, its often necessary to achieve the best result. Your future smile will be the better for it.
