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.

Most first-time root canal treatments achieve their purpose in saving an internally decayed tooth and extending its life to match those of the patient’s non-decayed teeth. Occasionally, though, a root canal-treated tooth may become re-infected by decay.
There are a number of reasons for this: the permanent crown meant to add further protection against decay may have been delayed, giving bacteria an opening to re-infect the tooth; it’s also possible the original seal for the pulp chamber and root canals after filling wasn’t sufficient to prevent bacterial contamination.
There‘s also another reason that’s very difficult to foresee — the presence of narrow, curved root canals in the tooth that can pose complications during the procedure. Some of these known as accessory or lateral canals branch off the main canals to create a complex network that’s difficult to detect during the initial procedure. If they’re not cleaned out and filled during the procedure any tissue trapped in them can remain infected and ultimately die. If these canals also open into the periodontal membrane at the attachment between the teeth and bone, the infection can spread there and become a periodontal (gum) infection that can trigger future tooth loss.
Fortunately, a reoccurrence of infection isn’t necessarily a death sentence for a tooth. A second root canal treatment can correct any problems encountered after the first treatment, especially complications from accessory canals. It may, though, require the advanced skills of an endodontist, a dental specialist in root canal problems. Endodontists use microscopic equipment to detect these smaller accessory canals, and then employ specialized techniques to fill and seal them.
If you encounter pain or other signs of re-infection for a tooth previously treated with a root canal procedure, contact us as soon as possible. The sooner we can examine and diagnose the problem, the better your tooth’s chances of survival by undergoing a second root canal treatment.

When your mouth is dry, you know it: that sticky, uncomfortable feeling when you first wake up or when you're thirsty. Fortunately, it usually goes away after you eat or drink. But what if your mouth felt like that all the time? Then, it's no longer an irritation—chronic dry mouth could also increase your risk of dental disease.
Chronic dry mouth occurs because of inadequate saliva flow. Saliva plays an important role in preventing dental disease because it neutralizes acid, which can cause the mineral content in tooth enamel to break down and lead to tooth decay. The mouth becomes more acidic right after eating, but saliva can restore its normal pH levels in about an hour—as well as some of the enamel's lost mineral content. Without saliva, your tooth enamel is at greater risk from acid.
While a number of things can potentially interfere with normal saliva production, medication is the most common. More than 500 prescription drugs, including many antihistamines, diuretics or antidepressants, can cause dry mouth. Cancer radiation or chemotherapy treatment and certain metabolic conditions like diabetes or Parkinson's disease can also increase symptoms.
If you are experiencing unusual dry mouth symptoms, see your dentist first for a full examination. Your dentist can measure your saliva flow, check your prescriptions and medical history, and examine your salivary glands for abnormalities. With this more accurate picture of your condition, they can help direct you to the most effective remedies and treatments for the cause.
If medication is the problem, you can talk to your doctor about alternative prescriptions that have a lesser effect on saliva flow. You can also drink more water before and after taking oral medication and throughout the day to help lubricate your mouth. Chewing gums or mints with xylitol, a natural alcohol sugar, can also help: xylitol helps reduce the mouth's bacterial levels, as well as stimulate saliva flow.
Easing your dry mouth symptoms can make your life more pleasant. More importantly, it can reduce your risk of future dental problems caused by a lack of saliva.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.
Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.
Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”
Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.
There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.
So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.
Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”
