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.

Saliva probably doesn’t rate high on your amazement meter. You’re more likely to notice its absence and the dry irritation that results.
But you might be more impressed with this unsung bodily fluid if you knew all the things it does. It’s definitely a multi-tasker, performing a number of jobs (including aiding in digestion) that not only keep your oral health on track, but your general well-being too. And there are even new testing methods where saliva may even tell us when you’re not doing so well.
Here are 3 more tasks your saliva is doing for your mouth right now that truly makes it amazing.
Cleansing. Your teeth’s chewing action shreds food so it’s easier to digest. But that also leaves behind tiny particles in your mouth. Bacteria feast on these particles (especially carbohydrates like sugar) and produce acid as a byproduct, which can increase your risk of tooth decay. Saliva serves as a kind of “rinse cycle” for your mouth, helping to wash a good bit of these errant particles down your throat and away from hungry bacteria.
Defense. Speaking of bacteria, your mouth is home to millions of them. While most are harmless or even beneficial, a fraction can harm your teeth and gums. Saliva is your first line of defense, emitting an antibody known as Immunoglobulin A that targets these bacteria. Saliva also produces an antibacterial substance called lyzozyme that prevents bacteria from growing.
Enamel Protection. Although it’s the strongest substance in the body, your teeth’s enamel can’t withstand the effects of mouth acid, the by-product of bacterial feeding and growth. Acid levels naturally rise after eating; but even this sudden rise can begin the process of demineralization where minerals in enamel dissolve. Saliva saves the day by first neutralizing the acid and restoring the mouth’s normal pH in about thirty minutes to an hour. It also helps restore minerals in enamel, a process called remineralization. It’s all in a day’s work for this remarkable fluid.

After ruling out other possibilities for your constant jaw joint pain, your doctor has diagnosed you with a temporomandibular disorder (TMD). Now that you know what you have, what can you do about it?
Unfortunately, it's not always an easy answer. Ideas about treatment are almost as numerous as theories on the causes of TMD. By and large, though, we can classify treatment into two broad categories: conservative and aggressive.
The conservative approach is the result of many years of experimentation and application; it's also much less invasive than aggressive treatments. For most patients, though, these treatments can offer significant relief from pain and dysfunction.
Conservative treatments are based primarily on the philosophy that the temporomandibular joint is like any other joint, and should be treated that way. Treatments include thermal therapies like ice or heat packs applied to the jaw, physical therapy (gentle stretching, jaw exercise, and massage) and pain and muscle relaxant medication. In cases where teeth grinding may be a contributing factor, we might recommend a bite guard worn in the mouth to reduce biting pressure.
On the other end of the spectrum are treatments like altering the bite or the position of the jaw. The purpose of bite alteration is to change the dynamic when the jaws are in contact during chewing or clenching, and reduce pressure on the joints. This is often done by reshaping the teeth's biting surfaces, moving the teeth with orthodontics or performing crown and bridgework. Another possibility, actually modifying the lower jaw location, requires surgery. All of these aggressive treatments are done in order of less to more invasiveness.
These more aggressive treatments, especially jaw surgery, are irreversible. Furthermore, studies on results have not been encouraging — there's no guarantee you'll receive relief from your symptoms. You should consider the aggressive approach only as a last resort, after you've tried more conservative measures. Even then, you should get a second opinion before undergoing more invasive procedures.
Hopefully, you'll see relief from therapies that have made a significant difference for most TMD sufferers. And that's our goal: to reduce your pain and dysfunction and help you regain your quality of life.
