When you look at the top row of a normal smile, you'll see symmetrical pairs: the central incisors in the middle, flanked by the lateral incisors and the canine (or eye) teeth on the outside of them.
Sometimes, though, teeth may not form as they should: in fact, it's one of the more common congenital defects with one in five people having missing or deformed teeth, often the upper lateral incisors. In the latter case, it's not uncommon for the eye teeth to drift into the missing lateral incisors' spaces next to the central incisors. This creates a smile even a layperson can tell is off.
There is a way to treat this with orthodontics and cosmetic dentistry that will transform that person's smile while restoring better mouth function too. It's often a long process, however, that's best begun early and must be precisely timed with dental development.
Using braces, we move the drifted teeth back to their proper positions, which will make room for a future dental restoration. It's usually best to begin this treatment during late childhood or early adolescence. The next step is to fill the newly-created space with prosthetic (false) teeth.
Dental implants are an ideal choice since they're durable and life-like, and won't require permanent alteration of adjacent teeth. They do, however, require a certain amount of bone volume at the site to support them; if the volume is insufficient we may have to place a bone graft to stimulate new growth.
It's also best not to install implants until the jaw has finished development, usually in the late teens or early adulthood. In the interim between tooth repositioning and implants we can customize a retainer or other removable appliance with a false tooth to occupy the space. This not only enhances the smile, it also prevents the repositioned teeth from drifting back.
These steps toward achieving a new smile take time and sometimes a team of specialists. But all the effort will be rewarded, as a person born without teeth can have a new smile and improved oral health.

The market for sugar alternatives has grown exponentially since saccharin was accidentally discovered in 1878. Today, saccharin has been joined by other FDA-approved zero-calorie artificial sweeteners, including aspartame (“Equal®” or “NutraSweet®”), sucralose (“Splenda®”) and rebaudioside A, derived from the stevia plant. You can also choose low-calorie alcohol sugars like erythritol or xylitol.
With rare exceptions, all these choices are widely considered safe substitutes for table sugar, high fructose corn syrup or other versions of this plentiful carbohydrate. Finding substitutes for sugar is a worthy health goal: besides its role in obesity, sugar is considered a contributing factor in cardiovascular disease and diabetes.
It's also a prime food for oral bacteria that cause dental disease. As bacteria consume sugar they produce acid as a byproduct. Acid softens and dissolves the mineral content in enamel, leading to erosion and the formation of cavities. While saliva normally neutralizes acid after we eat, constant snacking and higher quantities of sugar in our food make it difficult for it to control or neutralize acid in the oral environment.
Because most of us are hard-wired with a “sweet tooth,” it's difficult for many to cut back on sugar. Artificial sweeteners help reduce the amount of sugar in the diet with obvious benefits for general health. It can also make a big difference in your dental health by helping you prevent tooth decay.
One alcohol sugar may even go a step further. In addition to reducing the presence of sugar in the mouth, xylitol (found in chewing gums, candy and breath mints) also seems to reduce bacterial growth by interfering with their ability to ferment the sugar.
If you're considering using an artificial sweetener, get to know them first: some like aspartame aren't suitable for baked goods or cooking, while saccharine or sucralose are. People with a rare genetic condition called phenylketonuria also can't properly process aspartame in the body.
Be sure you also talk to us about artificial sweeteners' impact on oral health, especially the benefits of xylitol for dental care. Used in a wise and informed way, these sugar alternatives can improve both your oral and general health.

It might seem that supermodels have a fairly easy life — except for the fact that they are expected to look perfect whenever they’re in front of a camera. Sometimes that’s easy — but other times, it can be pretty difficult. Just ask Chrissy Teigen: Recently, she was in Bangkok, Thailand, filming a restaurant scene for the TV travel series The Getaway, when some temporary restorations (bonding) on her teeth ended up in her food.
As she recounted in an interview, “I was… like, ‘Oh my god, is my tooth going to fall out on camera?’ This is going to be horrible.” Yet despite the mishap, Teigen managed to finish the scene — and to keep looking flawless. What caused her dental dilemma? “I had chipped my front tooth so I had temporaries in,” she explained. “I’m a grinder. I grind like crazy at night time. I had temporary teeth in that I actually ground off on the flight to Thailand.”
Like stress, teeth grinding is a problem that can affect anyone, supermodel or not. In fact, the two conditions are often related. Sometimes, the habit of bruxism (teeth clenching and grinding) occurs during the day, when you’re trying to cope with a stressful situation. Other times, it can occur at night — even while you’re asleep, so you retain no memory of it in the morning. Either way, it’s a behavior that can seriously damage your teeth.
When teeth are constantly subjected to the extreme forces produced by clenching and grinding, their hard outer covering (enamel) can quickly start to wear away. In time, teeth can become chipped, worn down — even loose! Any dental work on those teeth, such as fillings, bonded areas and crowns, may also be damaged, start to crumble or fall out. Your teeth may become extremely sensitive to hot and cold because of the lack of sufficient enamel. Bruxism can also result in headaches and jaw pain, due in part to the stress placed on muscles of the jaw and face.
You may not be aware of your own teeth-grinding behavior — but if you notice these symptoms, you might have a grinding problem. Likewise, after your routine dental exam, we may alert you to the possibility that you’re a “bruxer.” So what can you do about teeth clenching and grinding?
We can suggest a number of treatments, ranging from lifestyle changes to dental appliances or procedures. Becoming aware of the behavior is a good first step; in some cases, that may be all that’s needed to start controlling the habit. Finding healthy ways to relieve stress — meditation, relaxation, a warm bath and a soothing environment — may also help. If nighttime grinding keeps occurring, an “occlusal guard” (nightguard) may be recommended. This comfortable device is worn in the mouth at night, to protect teeth from damage. If a minor bite problem exists, it can sometimes be remedied with a simple procedure; in more complex situations, orthodontic work might be recommended.
Teeth grinding at night can damage your smile — but you don’t have to take it lying down! If you have questions about bruxism, please contact us or schedule an appointment for a consultation.

Visiting the dentist for cleanings, checkups and needed dental work is one of the pillars of dental health, along with daily hygiene and a nutritious diet. But an estimated 50% of people have some form of anxiety about dental visits — and around 15% actually avoid care because of it.
If you feel nervous about dental visits, there are ways to reduce your anxiety. First and foremost is to find a compassionate provider you trust and feel comfortable around, who listens non-judgmentally to your concerns.
But that's only the beginning: depending on your degree of anxiety, you could require more help to relax through sedation medication. The drugs and methods used can induce various degrees of consciousness ranging from mild relaxation to more sleep-like states.
The most basic is oral sedation. Typically, this involves taking the medication by mouth about an hour before an appointment. You can take it by itself to increase relaxation or along with other forms of sedation (like inhaling nitrous oxide gas) or local anesthesia.
Beyond inhalation, a higher level of sedation involves injecting the medication into the blood stream through an intravenous (IV) drip. This induces a deeper “semi-awake” level of consciousness, but differs from general anesthesia, which places a patient into unconsciousness to block pain during a major procedure. With IV sedation you may still be able to respond to verbal commands or touch; and although you're monitored for vital signs you won't need medical assistance to maintain breathing and heart function.
With today's advanced sedation drugs and methods, we can control dosages to achieve just the right level of sedation, as well as reduce the amount of time the drug may affect you afterward in recovery. Many drugs also have an amnesiac effect so that you'll remember little if any about the procedure afterward.
Whether by mouth, inhalation or with an IV, sedation therapy can make a difference no matter what your level of anxiety. And if your dental visits continue to be comfortable and pleasant ones, you're more likely to receive the care you need to keep your teeth and gums healthy.

Since the late 19th Century, dentists have used established protocols to successfully prevent and treat tooth decay. But there've been changes to this approach the last few years to improve its effectiveness, changes we now refer to as Minimally Invasive Dentistry or MID.
The older approach for treating dental caries (tooth decay) follows the protocols established by Dr. G.V. Black, considered the father of modern dentistry. Black advocated removing not only decayed structure but also some of the healthier but vulnerable portions of a tooth, to avoid further decay and make the tooth easier to clean. This resulted in larger fillings, although they've become smaller as dental techniques have advanced.
MID, on the other hand, aims to remove as little tooth structure as possible while still effectively treating and preventing future decay. To achieve that goal we begin first with a complete assessment of a patient's individual decay risk, known as Caries Management By Risk Assessment (CAMBRA).
With CAMBRA, we're looking at other factors besides individual tooth health: a patient's hygiene, lifestyle and dietary habits; the types and amount of bacteria present; and the quality of saliva flow, needed to neutralize mouth acid. With these the results we develop a customized prevention and treatment strategy.
MID also focuses on detecting dental caries as early as possible. Besides traditional x-rays, we're beginning to use other methods like dental microscopes, laser fluorescence, infrared photography or optical scanning. Early detection leads to early intervention, and with techniques that are much less invasive than the traditional approach.
The new approach also changes how we repair decayed teeth. We're increasingly using air abrasion, a technology that uses fine particles in a pressurized air stream to remove softer decayed tooth material and less healthy structure than the traditional dental drill. We're also using composite resin and other advanced materials for filings: these tooth-colored materials are stronger than previous versions and are quickly taking the place of metal amalgam, requiring less structural removal to accommodate them.
MID's core principles are early disease detection, proactive prevention and treatment with less structural removal. With this enhanced approach to effective dentistry, we're keeping your teeth healthy with minimal discomfort, lower costs and less long-term impact.
