LasersPoisedtoTransformCurrentTreatmentforGumDisease

While lasers still seem like science fiction, they’ve been used commercially (and medically) for decades. But there’s still room for growth in practical applications with this developing technology. One promising area is in the treatment of periodontal (gum) disease.

Gum disease is a bacterial infection triggered by plaque, a thin film of bacteria and food particles caused by inadequate oral hygiene. The disease is highly destructive and can eventually lead to both tooth and bone loss. Treatment procedures vary widely, but they all have the same goal: remove the offending plaque and calculus (tartar) from tooth and gum surfaces. Without plaque the infection subsides and the gums can heal.

For decades now, dentists have removed plaque and calculus manually with special hand instruments or ultrasonic equipment. If the disease has advanced below the gum line or formed deep voids filled with infection called periodontal pockets, the dentist may also employ surgical techniques to access the infected areas.

While all these techniques have a long track record for effectiveness, they can cause the inadvertent destruction of healthy tissue, as well as create discomfort for some patients afterward. This is where a new protocol called Laser Assisted New Attachment Procedure (LANAP®) may be able to make a difference in the future.

With the LANAP® protocol, surgeons direct a laser beam of light through a fiber optic the width of three human hairs onto diseased tissue. The particular color of light interacts with the tissue, which contains the darkly-pigmented bacteria causing the disease, and “vaporizes” it. The beam, however, passes harmlessly through lighter-pigmented healthy tissue; as a result diseased tissue is eradicated with little to no harm to adjacent healthy tissue.

With these capabilities, trained dentists using LANAP® for gum disease treatment might be able to achieve conventional results with less tissue removal and bleeding, less discomfort for patients, and less tissue shrinkage than traditional procedures — and without scalpels or sutures. And some post-surgical studies have indicated LANAP® might also encourage gum tissue regeneration in the months following.

LANAP®, however, is still developing and requires further research. Thus far, though, the results have been encouraging. As laser technology advances, it’s quite possible tomorrow’s patient may experience less discomfort and more effective healing with their gum disease treatment.

WhyAlfonsoRibeiroIsGratefulforRootCanalTreatment

As the host of America's Funniest Home Videos on ABC TV, Alfonso Ribeiro has witnessed plenty of unintentional physical comedy…or, as he puts it in an interview with Dear Doctor–Dentistry & Oral Health magazine, "When people do stuff and you're like, 'Dude, you just hurt yourself for no reason!'" So when he had his own dental dilemma, Alfonso was determined not to let it turn onto an "epic fail."

The television personality was in his thirties when a painful tooth infection flared up. Instead of ignoring the problem, he took care of it by visiting his dentist, who recommended a root canal procedure. "It's not like you wake up and go, 'Yay, I'm going to have my root canal today!'" he joked. "But once it's done, you couldn't be happier because the pain is gone and you're just smiling because you're no longer in pain!"

Alfonso's experience echoes that of many other people. The root canal procedure is designed to save an infected tooth that otherwise would probably be lost. The infection may start when harmful bacteria from the mouth create a small hole (called a cavity) in the tooth's surface. If left untreated, the decay bacteria continue to eat away at the tooth's structure. Eventually, they can reach the soft pulp tissue, which extends through branching spaces deep inside the tooth called root canals.

Once infection gets a foothold there, it's time for root canal treatment! In this procedure, the area is first numbed; next, a small hole is made in the tooth to give access to the pulp, which contains nerves and blood vessels. The diseased tissue is then carefully removed with tiny instruments, and the canals are disinfected to prevent bacteria from spreading. Finally, the tooth is sealed up to prevent re-infection. Following treatment, a crown (cap) is usually required to restore the tooth's full function and appearance.

Root canal treatment sometimes gets a bad rap from people who are unfamiliar with it, or have come across misinformation on the internet. The truth is, a root canal doesn't cause pain: It relieves pain! The alternatives—having the tooth pulled or leaving the infection untreated—are often much worse.

Having a tooth extracted and replaced can be costly and time consuming…yet a missing tooth that isn't replaced can cause problems for your oral health, nutrition and self-esteem. And an untreated infection doesn't just go away on its own—it continues to smolder in your body, potentially causing serious problems. So if you need a root canal, don't delay!

If you would like additional information on root canal treatment, please contact us or schedule a consultation. You can learn more by reading the Dear Doctor magazine articles “A Step-By-Step Guide to Root Canal Treatment” and “Root Canal Treatment: What You Need to Know.”

CrownLengtheningCouldHelpwithTreatingHardtoReachCavities

There is a primary principle dentists follow regarding tooth decay—treat it as soon as you find it. Something as simple and routine as filling a cavity could prevent future tooth loss.

But treating a cavity at or below the gum line could be anything but simple and routine. Older adults who may also be dealing with gum recession are more likely to have these kinds of cavities where the gums block clear access to it.

But there is a way to access gum-covered cavities with a minor surgical procedure known as crown lengthening. Crown lengthening is commonly used in cosmetic dentistry to expose more of the visible teeth when there's an overabundance of gum tissue or if the teeth are disproportionately small. We can use it in this instance to surgically relocate the blocking gum tissue out of the way of the cavity.

After numbing the area with local anesthesia, tiny incisions will be made in the gums to create a tissue flap. After reshaping the underlying bone to recreate normal anatomy but at a different level, this flap is then moved and sutured to a new position. This exposes enough tooth structure so that the cavity can be repaired after gum healing.

As with any minor surgery, there's a very slight risk of bleeding and/or infection with crown lengthening. If you undergo this procedure, you'll receive post-care instructions for the first few days afterward including avoiding strenuous activities, eating only soft foods and using an ice pack the day of surgery to help control swelling.

This versatile procedure can help save a tooth that might otherwise be lost due to decay. And, it might even improve your appearance.

CatchRootResorptionEarlyforBestChancesofSavingYourTooth

As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.

Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb).  It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.

It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.

We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.

Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.

At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

UltrasonicPlaqueRemovalanEffectiveAlternativetoManualScaling

Undergoing regular dental cleanings is an essential part of periodontal (gum) disease prevention. While a daily habit of brushing and flossing cleans bacterial plaque from most tooth surfaces, it’s difficult to remove from places your brush or floss can’t access well. That, as well as hardened plaque deposits known as calculus, must be removed by a hygienist or dentist with a technique known as scaling.

Scaling is traditionally performed manually using specialized hand instruments known as scalers. Although hand scalers are quite effective, they must be used carefully to avoid damage to gum tissue or, during deeper cleaning known as root planing, the tooth roots. A different method for plaque removal known as ultrasonic scaling has grown in popularity as an alternative to manual scaling.

Ultrasonic scaling uses equipment emitting vibrational energy that crushes and loosens plaque and calculus, and disrupts growing bacterial colonies in biofilm. Plaque particles are then washed away using water irrigation. The most recent models of ultrasonic scalers have matched the effectiveness of hand scaling in removing plaque and calculus in shallow gum pockets, and surpassed the manual technique in cleaning out pockets greater than 4 mm. In experienced hands, they’re kinder to tooth structure and other tissues. Water irrigation also improves healing by removing bacteria and scaling by-products, which also makes the area easier to view by the hygienist.

On the other hand, any type of power scaler must be used with caution with patients who have pacemakers, and are not recommended for those with hypersensitive teeth or teeth that are in the early stages of de-mineralization. The technique may also produce an aerosol of finely misted particles (with possible contamination) that requires added measures to contain them.

For most patients, though, ultrasonic scalers are an effective tool for plaque and calculus removal. As ultrasonic devices continue to evolve, patients will ultimately benefit from greater comfort and reduced treatment times.
