MargotRobbieKnowsAGreatSmileIsWorthProtecting

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.

“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”

Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.

Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.

A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.

Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.

So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.

SettingtheRecordStraightonRootCanalTreatments

If there was an “Unsung Hero” award for dental procedures, the root canal treatment would win hands-down. Much aligned in popular culture, today’s root canal treatment is actually a valuable tool for saving teeth that would otherwise be lost. And contrary to popular belief, root canal treatments don’t cause pain — they relieve it.

To help you understand its true worth, here are some common questions and answers about the root canal treatment.

What problem does a root canal treatment fix?
A root canal treatment stops a bacterial infection that has invaded the innermost part of a tooth — the pulp — and is advancing toward the end of the root through small passageways known as root canals. Most people first notice the problem as a sharp pain in the affected tooth that may suddenly dissipate in a few days. The infection has attacked the inner pulp tissue, rich in nerve fibers; when the nerve fibers die they stop sending pain signals. The infection, however, hasn’t died: as it advances, you may then begin to experience pain when you bite down or when you encounter hot foods. You may also notice tenderness and swelling in nearby gums.

How does the procedure stop the infection?
A root canal treatment removes all the infected or dead tissue and cleanses the pulp chamber. We enter the pulp chamber through a small access hole created in the tooth’s biting surface. After tissue removal, we then “shape” and prepare the empty chamber and root canals (often with the aid of microscopic equipment) to be filled with a special filling. After filling, the tooth is then sealed to prevent re-infection (most often, we need to install a permanent crown at a subsequent visit for maximum protection).

How much pain can I expect during and after the procedure?
During the procedure, none — the tooth and surrounding gums are fully anesthetized before we begin the procedure. Afterward, you may experience mild discomfort for a few days that can be relieved with over-the-counter medications like aspirin or ibuprofen.

What’s the ultimate value for a root canal treatment?
The procedure can save a tooth severely damaged by the infection. Even covered by an artificial crown, a living tooth continuing to exist and function normally within the mouth is usually more conducive for optimum oral health than an artificial tooth replacement.

DentalVisitsareKeytoDetectingEarlyDevelopingToothDecay

Tooth decay is as relentless as it is destructive, and it makes little distinction between age, gender, ethnicity or social status. Although risk levels vary from person to person, we’re all potentially in the crossfire for this harmful disease. Getting ahead of it early could save your teeth.

Tooth decay begins with oral bacteria. While feeding on dental plaque that accumulates on the teeth, bacteria multiply and produce acid as a by-product. Too much acid softens and erodes tooth enamel, which enables decay to advance deeper into the tooth.

If it isn’t stopped, decay can eventually infect and weaken the roots and bone, and ultimately lead to a lost tooth. By stopping it as early as possible before it reaches the inner pulp and root canals, we can greatly limit the damage.

Regular dental care is crucial for early detection. Here’s how we can stay ahead of developing decay during dental visits.

Visible inspection. There are visible signs a trained dentist may notice that point to tooth decay. Besides an already formed hole or cavity, we might also pick up on other unusual appearances like white spot lesions: these slight blemishes often occur in the areas of contact with other teeth, which we can treat with topical fluoride.

X-rays. This tried and true diagnostic tool has been a mainstay of dental care for nearly a century. The images they produce can indicate decay as darker spots or areas on or within the tooth that may not yet be visible to the eye. And with advances in digital processing and more streamlined equipment, we can effectively do this with a very low dosage of radiation exposure.

Advanced technology. We’ve developed other means for better disease detection that complement x-rays and visual inspections. Specialized microscopes and lasers are now important tools for analyzing suspected areas of early decay.

Even if decay gets a foothold we can effectively stop it and restore a tooth with a root canal treatment or a similar procedure. The best outcome, though, is to not allow this destructive disease to get that far. With dedicated oral hygiene and regular dental visits that uncover early decay, chances are good your teeth can remain healthy for a lifetime.
