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.

Often as children grow older, their participation in sports or similar activities increases. While generally encouraged, this greater activity does increase injury risk, especially to the mouth.
In fact, the late childhood to early adulthood demographic is the most prone portion of the population to incur dental injuries. To complicate matters, their dental development is often incomplete, posing a number of treatment obstacles for an injured tooth.
For example, the primary means for preserving an injured adult tooth is a root canal treatment: damaged or diseased tissue within the pulp, the tooth’s innermost layer, is removed and the empty chamber and root canals filled and sealed to prevent infection. But while a fully matured tooth can function without the nerves and blood vessels of the pulp, a developing tooth needs these tissues for continued tooth formation. Otherwise, tooth development can stall and cause problems later on.
The most common solution for younger teeth is to remove any damaged tooth structure without disturbing the pulp if at all possible followed by a filling. That’s contingent, though, on whether we find the pulp unexposed or undamaged—if it is, we’ll try to remove only damaged or diseased pulp tissue and leave as much healthy tissue intact as possible. To aid with healing and tissue re-growth, we may also place medicinal stimulators between the pulp and the filling.
Jaw development may also pose a challenge if the injured tooth is too far gone and must be removed. Our best choice is to replace it with a dental implant; but if we install the implant while the jaw is still growing, it may eventually appear out of place with the rest of the teeth. It’s best to postpone an implant until full jaw maturity in early adulthood.
In the meantime we could provide a temporary solution like a removable partial denture or a modified bonded bridge that won’t permanently alter nearby teeth. These methods can adequately restore the function and appearance of missing teeth until the jaw is mature enough for an implant.
While injuries with young permanent teeth do pose extra challenges, we have effective ways to address them. With the right approach, the outcome can be just as successful as with a mature tooth.

A loose permanent tooth is not a good thing—and not something you should put off having examined. That’s because a loose tooth could soon become a lost tooth.
How we treat it depends on its underlying cause, which could be one of two types. One is primary occlusal trauma, meaning the affected tooth has experienced accidental trauma or higher biting forces than it normally encounters. This usually happens because of teeth grinding habits.
It could also be secondary occlusal trauma. Unlike primary trauma where the supporting gums and bone may be reasonably healthy, secondary trauma occurs because these structures have been severely damaged by periodontal (gum) disease. As the gums begin to detach from a tooth and its underlying bone deteriorates, even normal biting forces can loosen it.
If gum disease is present, our first priority is to bring it under control. We do this primarily by removing all dental plaque (a thin film of bacteria and food particles that triggers the infection and sustains it) and calculus or tartar (calcified plaque). This can take several sessions and, in the case of deep infection, may require a surgical procedure.
On the other hand, if teeth grinding is the primary cause, we’ll focus on minimizing the habit and its effects. One way is to create a custom-fitted guard worn to prevent upper and lower teeth from making solid contact. You may also need to improve your management of stress—another factor in teeth grinding—through medication, therapy or biofeedback.
In either case, improved periodontal health will help the gums naturally regain their strong attachment with help, if necessary, from gum tissue or bone grafting surgery. But this healing process can take time, so we may need to secure a loose tooth in the interim by splinting it to neighboring stable teeth. This usually requires bonding rigid material or metal across the back of all involved teeth or in a channel cut along the teeth’s biting surfaces. In this way the more stable teeth support the loose one.
Splinting may be temporary as the mouth heals from disease or trauma and the teeth regain their stability. In some cases, though, it may be permanent. Either way, dealing promptly with a loose tooth can help ensure it’ll survive—so see your dentist as soon as possible.
