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.

An estimated 50,000 Americans are expected to be diagnosed this year with some form of oral cancer. Five years from now, if current survival rates still apply (57%), a little more than half will still be alive. That's why the Oral Cancer Foundation designates each April as Oral Cancer Awareness Month to call attention to this serious disease, and what you can do to lower your risk of contracting it.
Oral cancer has one of the lowest survival rates among known cancers, mainly because it easily goes undetected until its later stages when known treatments aren't as effective. Patients don't always have overt symptoms or they mistake cancerous lesions for everyday mouth sores. On the other hand, early detection and treatment dramatically improve survivability.
Here are some things you can do to reduce your risk for oral cancer or improve your odds for early detection.
Don't use tobacco. If you're a smoker, you're five to nine times more likely to develop oral cancer than a non-smoker. Using smokeless snuff or chewing tobacco is also risky—four times the risk of non-users. And preliminary evidence suggests that e-cigarettes increase the risk of cancer as well.
Make better food choices. A diet heavy in processed foods, especially nitrites used in curing meats and other products, can damage cellular DNA and lead to cancer. On the other hand, natural foods like fresh fruits and vegetables contain nutrients that lower cancer risk. A nutritious diet also contributes to healthier teeth and gums.
Practice safer sex. While older adults have traditionally accounted for most oral cancer cases, there has been a recent, unsettling rise among younger people. Most researchers tie this to the Human Papilloma Virus (HPV 16), which is sexually transmitted. You can reduce your risk for contracting HPV 16 and subsequent oral cancer by following safe sex practices.
Undergo oral cancer screenings. Your semi-annual dental visits to clean your teeth are also a prime opportunity to check for oral abnormalities, especially if you're older. During an oral cancer screening we visually inspect your face, neck, lips and the inside of your mouth for any suspicious sores or discolorations. Early detection leads to better outcomes.
You should also modify your alcohol consumption—moderate to heavy drinkers have three to nine times greater risk for oral cancer than light or non-drinkers. And, you can further lower your risk of lip cancers by limiting your exposure to the sun and wearing protective sunscreen.
Oral cancer is a dangerous condition that could threaten your life. Regular dental care and healthy lifestyle practices can help lower your risk for encountering this deadly disease.
Advanced tooth decay is a serious dental problem that can threaten an affected tooth's survival. But for decades now dentists have reliably used root canal treatment to better a decayed tooth's odds. This routine procedure performed with dental drill and special hand tools removes infected tissue inside a tooth and replaces the voids with a filling to prevent future infection.
But now there's a new way to perform a root canal—with a surgical laser. Lasers, amplified and focused light beams, aren't new to healthcare—they're an integral feature of many routine medical treatments and surgeries. But their use is relatively new to dentistry, and to endodontics (treating the interior of teeth) in particular.
Lasers can be used in root canal treatment to perform a number of tasks. They can remove diseased tissue and other debris from the innermost tooth pulp. They can be used to clean and shape root canal walls in preparation for filling. And they can also be used to soften and mold the filling material to fit more precisely within a tooth's particular root canal network.
Although laser-assisted root canal therapy isn't yet widespread, laser's limited use to date has given us a fair picture of both their advantages and disadvantages. As with other medical laser applications, lasers are very precise in removing diseased tissue without too much disruption of healthy tissue. There's less need for anesthesia than with dental drills, and lasers are a lot less noisy and jarring. Patients by and large experience less bleeding, as well as less discomfort or infection afterward.
But because laser light can only travel in a straight line, they're difficult to use in many tightly curved root canals. In these cases, the traditional methods are better suited, although a laser can be used in conjunction with other tasks. Temperature with lasers must also be carefully managed lest the high heat that's often generated damages natural tissues.
Although lasers won't be replacing traditional treatment methods for decayed teeth in the foreseeable future, there's hope they'll become more commonplace as technology and techniques continue to advance. Lasers can only improve what already is an effective means of saving teeth.
