Dental patients have amazing options for tooth replacement. Dental implants, for example, can replace the entire tooth, root and crown, giving patients a new tooth nearly as good as the old one.
Nearly—but not exact. Even implants can't match the full benefits of a natural tooth, including one in less than perfect shape. Our first goal as dentists, then, is to save a diseased tooth if at all practical before considering replacing it.
That often involves a root canal treatment to address decay threatening a tooth's interior. The procedure requires drilling into the tooth to access its innermost pulp, cleaning out the pulp and root canals, and then filling the empty spaces. Since all dentists are trained in basic root canal treatment, your general dentist may be able to perform it.
But some dental situations call for more advanced endodontics, the dental specialty for treating disease and other problems inside a tooth. So, in what situations would you see an endodontist?
When your dentist refers you. Your dentist wants you to receive the level of treatment necessary to save your tooth. After examination, they may determine your situation would be better served by the advanced training, equipment and techniques (including surgery) of an endodontist.
When your tooth has complications. Patients often need an endodontist when existing factors complicate treatment of advanced tooth decay. A patient may have dental pain that's difficult to pinpoint, requiring the diagnostic resources of an endodontist. It's also common for a tooth's root canal network to be highly intricate, and which respond better to treatment with specialized endodontic tools and techniques.
When root canal treatment fails. Most root canal treatments are successful in protecting the tooth from further infection. That said, it's still possible for a root-canaled tooth to become re-infected or develop more problems. Again, an endodontist and their “tool chest“ re-treating a root-canaled tooth may be the best option for saving it.
You also don't have to wait for a referral—you can see an endodontist if you believe they would be best to treat your decayed tooth. You can find one near you by visiting an online endodontist directory at www.aae.org/find. An endodontist may be the lifesaver your diseased tooth needs.
You can't correct a poor bite with braces or clear aligners overnight: Even the most cut-and-dried case can still require a few years to move teeth where they should be. It's a welcome relief, then, when you're finally done with braces or aligner trays.
That doesn't mean, however, that you're finished with orthodontic treatment. You now move into the next phase—protecting your new smile that took so much to gain. At least for a couple of more years you'll need to regularly wear an orthodontic retainer.
The name of this custom-made device explains its purpose: to keep or “retain” your teeth in their new, modified positions. This is necessary because the same mechanism that allows us to move teeth in the first place can work in reverse.
That mechanism centers around a tough but elastic tissue called the periodontal ligament. Although it primarily holds teeth in place, the ligament also allows for tiny, gradual tooth movement in response to mouth changes. Braces or aligner trays take advantage of this ability by exerting pressure on the teeth in the direction of intended movement. The periodontal ligament and nature do the rest.
But once we relieve the pressure when we remove the braces or aligners, a kind of “muscle memory” in the ligament can come into play, causing the teeth to move back to where they originally were. If we don't inhibit this reaction, all the time and effort put into orthodontic treatment can be lost.
Retainers, either the removable type or one fixed in place behind the teeth, gently “push” or “pull” against the teeth (depending on which type) just enough to halt any reversing movement. Initially, a patient will need to wear their retainer around the clock. After a while, wear time can be reduced to just a few hours a day, usually during sleep-time.
Most younger patients will only need to wear a retainer for a few years. Adults who undergo teeth-straightening later in life, however, may need to wear a retainer indefinitely. Even so, a few hours of wear every day is a small price to pay to protect your beautiful straightened smile.
If you would like more information on orthodontic retainers, please contact us or schedule an appointment for a consultation. You can also learn more about this topic by reading the Dear Doctor magazine article “The Importance of Orthodontic Retainers.”
The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.
While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”
The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.
Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.
Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.
Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.
Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.
Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
