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.
Over the years, dentists have become quite proficient in treating even the most severe periodontal (gum) disease. Many of these positive outcomes are achieved through manual effort using simple hand instruments called scalars and conventional periodontal surgery.
But that might be changing soon: Periodontists (specialists who care for the gums and other supporting dental structures) are starting to use a different kind of tool for gum disease treatment—surgical lasers.
Although lasers are more commonplace in other fields of medicine, recent developments hint at a more prominent future role for them in dentistry. One of these developments is a laser procedure called Laser Assisted New Attachment Procedure (LANAP®) that treats deep spaces of infection called periodontal pockets, which develop advanced gum disease.
These pockets form as infected gums gradually detach from a tooth as the supporting bone is lost. This widens the normally narrow gap between the teeth and gums. The ensuing pocket fills with infection that must be removed to adequately treat the gum disease. As the pocket extends down to the root, it's often necessary to perform a surgical procedure through the adjacent gum tissue to fully access it.
But with the LANAP® procedure, the dentist can use a laser to access a deep pocket without opening the gums. Moving from above into the gap between the tooth and gums, the light from the laser has the ability to remove diseased tissue without damaging healthy tissue.
The dentist follows this with ultrasonic equipment and manual scalers to further decontaminate the tooth root surface. The laser is then employed once again to facilitate the formation of a blood clot between the teeth and gums to seal the area with a fibrin clot. Once treated, the dentist will monitor the tooth to ensure maximum bone regeneration and gum reattachment.
Although outcomes are the same for the most part, this laser technique for periodontal pockets may have some advantages over conventional surgery. Studies so far show that LANAP® causes less tissue removal and bleeding, less potential for gum recession and less discomfort experienced by patients.
It's not likely that lasers will fully replace conventional gum disease treatments any time soon. But if the encouraging evidence thus far continues, the laser will one day become as commonplace alongside the other tools used for gum disease treatment.

The straightening process for a crooked smile doesn't end when the braces come off. There's one more crucial phase to undergo to make sure we don't lose the progress you've achieved: wearing an orthodontic retainer.
Although often viewed as a nuisance, retainers are important because they prevent realigned teeth from reverting to their old positions. This is possible because the periodontal ligament, the gum attachment that allows us to move teeth in the first place, can contain “muscle memory” that naturally tries to draw teeth back to where they once were.
A retainer prevents this from happening: During wear the subtle pressure they exert keeps or “retains” the teeth in their new positions until they're firmly established, usually after several months. While most patients initially wear a retainer around the clock, this will gradually taper off until they're worn primarily during sleep hours.
While retainers come in many different styles and sizes, most fall into one of two categories: removable or non-removable (bonded). The first type, a custom-made appliance a patient can easily take in and out of the mouth, has its advantages. Removing it makes it easier to clean the teeth. They're also adaptable to reduced wear schedules for eating, brushing and flossing, or for special occasions.
But a removable retainer may be noticeable to others. Its removability can also lead to problems. Out of the mouth they're prone to be lost, resulting in additional replacement costs. And immature patients may be easily tempted to take them out too often—or not wear them at all.
A bonded retainer solves many of these potential problems. Because the retainer wire is securely bonded to the back of the teeth, it's not visible to others. And because it can't be removed except by an orthodontist, there's virtually no chance of losing it or haphazard wear.
On the other hand, bonded retainers can occasionally break, requiring repair or replacement. And flossing is more difficult than with a removable retainer, although a little training from a dental hygienist can make that easier.
The choice of retainer depends on the individual and their priorities. But whether removable or bonded, a retainer is absolutely essential for protecting your new, hard-earned smile.

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.

What happens when you lose a tooth? In the short-run, it can certainly undermine your appearance and ability to efficiently chew and digest food. But a chain of events could also be set in motion that may cause the most harm to your appearance and health—and it all has to do with bone loss.
Our bones aren't just rigid structures providing a frame for our bodies. They're living tissue with other purposes like producing blood cells and regulating the endocrine system. Bone tissue is constantly replenishing itself as older cells die and newer ones take their place.
In the jawbone, the pressure generated by the teeth while biting and chewing travels through the roots to stimulate the growth of new bone. If a tooth goes missing, however, the bone around the tooth also loses this growth stimulus.
This can cause normal bone growth to slow so that dying bone cells aren't sufficiently replaced. The bone may then diminish at an alarming rate—a decrease in width of about 25% in the first year after a tooth loss and several millimeters in height after only a few years.
This bone loss can continue to advance, especially if multiple teeth are lost, until the jaw structure as a whole loses significant height. The bite may then collapse, forcing the front teeth to push forward. In this state, a person may not be able to adequately bite or chew food. It can also damage their appearance—their smile suffers, of course, but their entire face may also appear shrunken.
You may be able to avoid this scenario if you replace missing teeth with dental implants. In addition to their life-likeness and durability, implants can also stop or slow bone loss. This is because titanium, the principle metal used in an implant, has a strong affinity with bone: Bone cells readily grow and attach to the titanium surface and foster new growth.
But don't wait: Bone loss could eventually extend beyond what an implant can accommodate—you may then need grafting to build up the bone or consider a different type of restoration. So, speak with your dentist as soon as possible about an implant restoration for a lost tooth to help avoid significant bone loss.
