Since their development in the laboratory over five decades ago, lasers have found increasing use in our everyday lives. In the field of medicine, it’s not uncommon to find lasers in the offices of dermatologists, ophthalmologists and surgeons, to name just a few. Now, some dentists are finding that lasers can offer an alternative means of treating gum disease — and one that may have advantages in certain situations.
You probably know that a laser produces a special kind of light — in fact, its name is an acronym for “Light Amplification by Stimulated Emission of Radiation.” Essentially, a medical laser uses electrical energy to produce an intense and narrow beam of concentrated light. This light can be directed to a particular area, often via a fiber-optic channel. The laser’s precision allows a doctor or technician to focus the light energy exactly where it’s needed — to remove diseased tissue, seal off blood vessels, and sterilize a wound, for example.
For several years, periodontists — dentists who specialize in treating diseases of the gums — have been researching the use of lasers for treating certain types of gum disease. In standard clinical practice, hand-held instruments and ultrasonic cleaning tools are used at regular time intervals (3 – 6 months) to remove the sticky bacterial biofilm, as well as calculus (tartar), that forms in between teeth and gums. If that still isn't effective, gum surgery may be required to access the affected area, remove diseased tissue, and reduce pocket depth (the space below the gum line that gets larger as bone loss occurs) to prevent reinfection.
Recently, however, several new procedures have been developed that use lasers to accomplish some or all of these goals. One type of therapy uses a special laser that emits pulses of light with a specific wavelength (color) of 1064 nanometers. This light passes through healthy cells like a sunbeam through a window — but when it encounters darkly-pigmented bacteria, it vaporizes them instantly!
One of the potential advantages of laser treatment is its precision: focused directly on the area where trouble occurs, it targets diseased tissue but leaves healthy tissue alone. Another is that laser treatment is less invasive: It requires less tissue removal, and may cause less discomfort and tissue shrinkage (gum recession) than conventional periodontal surgery. And because it produces small amounts of heat, it can seal blood vessels and help control bleeding.
While lasers have long shown promise for treating gum disease, until recently it wasn’t clear if they offered any advantages over traditional methods. Now, several studies have shown that certain laser treatments can be just as effective as traditional gum surgery in many cases — with the potential benefit of being less invasive. In the future, the use of lasers for periodontal procedures is likely to increase.
It’s important to remember that no single treatment — not even a laser — can “zap” gum disease in one fell swoop. Controlling periodontal disease requires effective at-home oral hygiene combined with regular professional care.

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.

What's an actor's most important feature? According to Vivica A. Fox, whose most recent big-screen role was in Independence Day: Resurgence, it's what you see right up front.
"On screen, your smile and your eyes are the most inviting things that bring the audience in" she said. "Especially if you play the hot chick."
But like lots of people, Vivica reached a point where she felt her smile needed a little help in order to look its best. That's when she turned to a popular cosmetic dental treatment.
"I got veneers years ago," Ms. Fox told Dear Doctor magazine in a recent interview, "just because I had some gapping that probably only I noticed."
What exactly are dental veneers? Essentially, they are thin shells of lustrous porcelain that are permanently attached to the front surfaces of the teeth. Tough, lifelike and stain-resistant, they can cover up a number of defects in your smile — including stains, chips, cracks, and even minor spacing irregularities like the ones Vivica had.
Veneers have become the treatment of choice for Hollywood celebs — and lots of regular folks too — for many reasons. Unlike some treatments that can take many months, it takes just a few appointments to have veneers placed on your teeth. Because they are custom made just for you, they allow you to decide how bright you want your smile to be: anywhere from a natural pearly hue to a brilliant "Hollywood white." Best of all, they are easy to maintain, and can last for many years with only routine care.
To place traditional veneers, it's necessary to prepare the tooth by removing a small amount (a millimeter or two) of its enamel surface. This keeps it from feeling too big — but it also means the treatment can't be reversed, so once you get veneers, you'll always have them. In certain situations, "no-prep" or minimal-prep veneers, which require little or no removal of tooth enamel, may be an option for some people.
Veneers aren't the only way to create a better smile: Teeth whitening, crowns or orthodontic work may also be an alternative. But for many, veneers are the preferred option. What does Vivica think of hers?
"I love my veneers!" she declared, noting that they have held up well for over a decade.
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.

Magician Michael Grandinetti mystifies and astonishes audiences with his sleight of hand and mastery of illusion. But when he initially steps onto the stage, it’s his smile that grabs the attention. “The first thing… that an audience notices is your smile; it’s what really connects you as a person to them,” Michael told an interviewer.
He attributes his audience-pleasing smile to several years of orthodontic treatment as a teenager to straighten misaligned teeth, plus a lifetime of good oral care. “I’m so thankful that I did it,” he said about wearing orthodontic braces. “It was so beneficial. And… looking at the path I’ve chosen, it was life-changing.”
Orthodontics — the dental subspecialty focused on treating malocclusions (literally “bad bites”) — can indeed make life-changing improvements. Properly positioned teeth are integral to the aesthetics of any smile, and a smile that’s pleasing to look at boosts confidence and self-esteem and makes a terrific first impression. Studies have even linked having an attractive smile with greater professional success.
There can also be functional benefits such as improved biting/chewing and speech, and reduced strain on jaw muscles and joints. Additionally, well-aligned teeth are easier to clean and less likely to trap food particles that can lead to decay.
The Science Behind the Magic
There are more options than ever for correcting bites, but all capitalize on the fact that teeth are suspended in individual jawbone sockets by elastic periodontal ligaments that enable them to move. Orthodontic appliances (commonly called braces or clear aligners) place light, controlled forces on teeth in a calculated fashion to move them into their new desired alignment.
The “gold standard” in orthodontic treatment remains the orthodontic band for posterior (back) teeth and the bonded bracket for front teeth. Thin, flexible wires threaded through the brackets create the light forces needed for repositioning. Traditionally the brackets have been made of metal, but for those concerned about the aesthetics, they can also be made out of a clear material. Lingual braces, which are bonded to the back of teeth instead of the front, are another less visible option. The most discrete appliance is the removable clear aligner, which consists of a progression of custom-made clear trays that reposition teeth incrementally.
How’s that for a disappearing act?!
