LocalAnesthesiaTakesthePainOutofMostDentalWork

Long ago dental work could be painful and stressful—often for both patient and practitioner. Thankfully, that time is long past: today, most procedures are painless in large part due to local anesthesia.

Local anesthetics are numbing substances applied to specific areas of the body like the teeth and gums to temporarily block pain during a procedure. And because they only affect a localized area of the body, you remain conscious and alert throughout the procedure.

To achieve the level of numbing necessary for dental work, we often need to deaden the gums using a needle to deliver the anesthetic. But then this poses a secondary pain concern—the needle stick itself.

Again, topical anesthesia comes to the rescue in the form of a swab, patch or spray applying an anesthetic directly to the top layer of the gums at the injection site. This numbs the area and prevents you from feeling the needle stick. It's highly probable, therefore, that from start to finish you won't feel any discomfort during your dental work except perhaps for a little pressure.

Local anesthesia truly is a game changer for dental care—and not just for the patient. A dentist who's concerned about their patient's comfort level may work hurriedly to complete a procedure. But if their patient is relaxed, the dentist can work calmly and methodically. The result is better, more focused care.

For all its improvements in the patient experience, though, there has been one consistent complaint—the numbness that often lingers for a while after the procedure is over. But there have been advances in recent years that have helped reduce this irritation: new anesthetic agents (even some that can reverse the anesthetic effect) and fine-tuned dosages can help keep residual numbing to a minimum.

Not all procedures like routine teeth cleanings or enamel shaping require anesthesia. But when it's appropriate, local anesthesia can make your next dental visit much more pleasant.

DentalSealantscanhelpPreventToothDecayinChildren

While children are less likely than adults to experience periodontal (gum) disease, the same can't be said for tooth decay. One aggressive form of decay called early childhood caries (ECC) can have a profound effect on a child's dental development and future health.

That's why dentists who treat young children often use a variety of preventive measures to reduce the risk of ECC and other dental diseases. One popular method is dental sealants, dental material coatings applied to the biting surfaces of teeth that fill in the naturally occurring pits and crevices. These areas are highly susceptible to plaque formation, a bacterial biofilm of food particles that tends to accumulate on teeth. It's the bacteria that live in plaque that are most responsible for the formation of tooth decay.

Roughly one third of children between the ages of 6 and 11 have received some form of dental sealant. It's a quick and painless procedure applied during a routine office visit. The dentist brushes the sealant in liquid form on the teeth, and then hardens it with a special curing light. It's common for children to begin obtaining sealant protection as their molars begin to come in.

With their increased popularity among dentists, researchers have conducted a number of studies to see whether dental sealants have a measurable effect reducing tooth decay. After reviewing the cases of thousands of children over several years, many of these studies seemed to show that children who didn't receive sealants were more than twice as likely to get cavities as children who did.

As evidence continues to mount for dental sealants' effectiveness protecting young children from decay, both the American Dental Association and the American Academy of Pediatric Dentistry now recommend it for all children. Not only can sealants help preserve children's teeth now, but they can reduce future costs for dental treatment that results from tooth decay.

ANewVeneerwithMinimalorNoToothAlteration

Dental veneers, thin layers of porcelain bonded to chipped, stained or slightly crooked teeth, are an effective and affordable way to transform your smile. Their color, translucence and shape blend so well with the rest of your teeth that it's often difficult to tell them apart.

But traditional veneers have one drawback: although they're less than a millimeter in width, they can still appear bulky on unprepared teeth. To help them look more natural, we often have to remove some of the enamel layer from the tooth surface. Enamel doesn't grow back, so this alteration is permanent and the prepared teeth will require a restoration from then on.

But you may be able to avoid this—or at least keep the alteration to a minimum—with no-prep or minimal-prep veneers, two new exciting choices in cosmetic dentistry. About the width of a contact lens, we can bond these much thinner veneers to teeth with virtually no preparation at all or, in the case of a minimal-prep veneer, needing only an abrasive tool to reshape and remove only a tiny bit of the enamel.

These ultra thin veneers are best for teeth with healthy enamel, and can be placed in as few as two appointments. And besides being less invasive, the procedure is reversible—we can remove them and you can return to your original look without any follow-up restoration. One caveat, though: because of the strong bonding process used, it's not always easy to remove them.

Although their thinness makes it possible to avoid or minimize alterations, there are some dental situations like oversized teeth that may still require extensive tooth preparation. With some poor bites (malocclusions) orthodontic treatment to straighten the teeth may also be needed first.

All in all, though, no-prep or minimal-prep veneers could help you avoid the permanent tooth alteration that usually accompanies their thicker cousins. What's more, you'll have the beautiful, transformed smile that veneers can achieve.

HowKathyBatesRetainsHerMovie-StarSmile

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.

When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”

Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.

There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.

By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.

So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

If you would like more information about orthodontic retainers, please contact us or schedule an appointment for a consultation. You can learn more about this topic in the Dear Doctor magazine articles “Why Orthodontic Retainers?” and “The Importance of Orthodontic Retainers.” The interview with Kathy Bates appears in the latest issue of Dear Doctor.

WisdomTeethWarrantCloseWatchtoAvoidFutureHealthIssues

As permanent teeth gradually replace primary (“baby”) teeth, most will come in by early adolescence. But the back third molars—the wisdom teeth—are often the last to the party, usually erupting between ages 18 and 24, and the source of possible problems.

This is because the wisdom teeth often erupt on an already crowded jaw populated by other teeth. As a result, they can be impacted, meaning they may erupt partially or not at all and remain largely below the gum surface.

An impacted tooth can impinge on its neighboring teeth and damage their roots or disrupt their protective gum attachment, all of which makes them more susceptible to tooth decay or periodontal (gum) disease. Impacted teeth can also foster the formation of infected cysts that create areas of bone loss or painful infections in the gums of other teeth.

Even when symptoms like these aren’t present, many dentists recommend removing the wisdom teeth as a preemptive measure against future problems or disease. This often requires a surgical extraction: in fact, wisdom teeth removal is the most common oral surgical procedure.

But now there’s a growing consensus among dentists that removing or not removing wisdom teeth should depend on an individual’s unique circumstances. Patients who are having adverse oral health effects from impacted wisdom teeth should consider removing them, especially if they’ve already encountered dental disease. But the extraction decision isn’t as easy for patients with no current signs of either impaction or disease. That doesn’t mean their situation won’t change in the future.

One way to manage all these potentialities is a strategy called active surveillance. With this approach, patient and dentist keep a close eye on wisdom teeth development and possible signs of impaction or disease. Most dentists recommend carefully examining the wisdom teeth (including diagnostic x-rays and other imaging) every 24 months.

Following this strategy doesn’t mean the patient won’t eventually have their wisdom teeth removed, but not until there are clearer signs of trouble. But whatever the outcome might be, dealing properly with wisdom teeth is a high priority for preventing future oral health problems.
