After months of wearing braces, the big day has arrived — they’re finally off! Your teeth have been realigned and your smile is dazzling. You’re finished with orthodontic treatment, right?
Not quite — because if you want to keep your new smile you have one more treatment phase to go — wearing a retainer. Without this phase there’s a distinct possibility you could lose all the time, effort and expense of braces because your teeth could revert to their previous position.
To understand why, we have to consider how teeth can move in the first place. Although it may seem like your teeth are rigidly fastened to the jawbone, they’re actually held in place by the periodontal ligament, a strong, elastic gum tissue that lies between the teeth and the bone. Tiny fibers from the ligament attach to the teeth on one side and to the bone in a similar manner on the other side.
When pressure is applied to the tooth as happens with braces, the bone around the side of the tooth in the direction of the force will begin to dissolve (resorb), allowing the tooth to move in that direction. New bone will then build up on the other side to stabilize the tooth. Once the pressure is removed (when we take the braces off), there’s a tendency for the teeth, bone and gums to “remember” the old position and try to revert back.
The answer is a removable mouth appliance known as a retainer. Custom-designed to fit the teeth’s new position, the retainer helps hold the teeth in place until the bone completely sets around them. In the beginning, you may need to wear the retainer around the clock and then later only at night while you sleep. While you may only need to wear it for a few months (especially if you’re an adolescent or young adult) some patients may need to wear some form of retainer indefinitely. Your orthodontist will advise you how long depending on your individual situation.
While retainers may seem like an inconvenience, they’re extremely important for keeping or “retaining” the teeth in their new and better position. Following through on this important phase of treatment will help ensure you’ll keep your new smile for a long time to come.

While the sport of golf may not look too dangerous from the sidelines, players know it can sometimes lead to mishaps. There are accidents involving golf carts and clubs, painful muscle and back injuries, and even the threat of lightning strikes on the greens. Yet it wasn’t any of these things that caused professional golfer Danielle Kang’s broken tooth on the opening day of the LPGA Singapore tournament.
“I was eating and it broke,” explained Kang. “My dentist told me, I've chipped another one before, and he said, you don't break it at that moment. It's been broken and it just chips off.” Fortunately, the winner of the 2017 Women’s PGA championship got immediate dental treatment, and went right back on the course to play a solid round, shooting 68.
Kang’s unlucky “chip shot” is far from a rare occurrence. In fact, chipped, fractured and broken teeth are among the most common dental injuries. The cause can be crunching too hard on a piece of ice or hard candy, a sudden accident or a blow to the face, or a tooth that’s weakened by decay or repetitive stress from a habit like nail biting. Feeling a broken tooth in your mouth can cause surprise and worry—but luckily, dentists have many ways of restoring the tooth’s appearance and function.
Exactly how a broken tooth is treated depends on how much of its structure is missing, and whether the soft tissue deep inside of it has been compromised. When a fracture exposes the tooth’s soft pulp it can easily become infected, which may lead to serious problems. In this situation, a root canal or extraction will likely be needed. This involves carefully removing the infected pulp tissue and disinfecting and sealing the “canals” (hollow spaces inside the tooth) to prevent further infection. The tooth can then be restored, often with a crown (cap) to replace the entire visible part. A timely root canal procedure can often save a tooth that would otherwise need to be extracted (removed).
For less serious chips, dental veneers may be an option. Made of durable and lifelike porcelain, veneers are translucent shells that go over the front surfaces of teeth. They can cover minor to moderate chips and cracks, and even correct size and spacing irregularities and discoloration. Veneers can be custom-made in a dental laboratory from a model of your teeth, and are cemented to teeth for a long-lasting and natural-looking restoration.
Minor chips can often be remedied via dental bonding. Here, layers of tooth-colored resin are applied to the surfaces being restored. The resin is shaped to fill in the missing structure and hardened by a special light. While not as long-lasting as other restoration methods, bonding is a relatively simple and inexpensive technique that can often be completed in just one office visit.

Overbites, underbites, crossbites—these are just a few of the possible malocclusions (poor bites) you or a family member might be experiencing. But no matter which one, any malocclusion can cause problems.
Besides an unattractive smile, a malocclusion makes it more difficult to chew and to keep the teeth and gums clean of disease-causing bacterial plaque. Thus correcting a malocclusion improves dental health; a more attractive smile is an added bonus.
This art of correction—moving teeth back to the positions where they belong—is the focus of a dental specialty called orthodontics. And, as it has been for several decades, the workhorse for achieving this correction is traditional braces.
Braces are an assembly of metal brackets affixed to the teeth through which the orthodontist laces a metal wire. The wire is anchored in some way (commonly to the back teeth) and then tightened to apply pressure against the teeth. Over time this constant and targeted pressure gradually moves the teeth to their new desired positions.
The reason why this procedure works is because teeth can and do move naturally. Although it may seem like they’re rigidly set within the jawbone, teeth are actually held in place by an elastic tissue network known as the periodontal ligament. The ligament lies between the tooth and bone and keeps the tooth secure through tiny fibers attached to both it and the bone. But the ligament also allows teeth to continually make micro-movements in response to changes in chewing or other environmental factors.
In a sense, braces harness this tooth-moving capability like a sail captures the wind propelling a sailboat. With the constant gentle pressure from the wires regularly adjusted by the orthodontist, the periodontal ligament does the rest. If all goes according to plan, in time the teeth will move to new positions and correct the malocclusion.
In a way, braces are the original “smile makeover”—once crooked teeth can become straight and more visually appealing. More importantly, though, correcting a poor bite improves how the mouth works, especially while eating, and keeping things clean. A straighter smile isn’t just more attractive—it’s healthier.

For best results in cleaning your teeth of disease-causing plaque you need both the power of brushing open teeth surfaces and flossing in between them. But you may be wondering: should you perform one task before the other?
In general terms, no—there’s no solid evidence that flossing is better before brushing, or vice-versa. But that being said we do recognize each way has its own advantages.
If you floss before brushing, it’s possible you could loosen plaque that can then be easily brushed away when you perform your second hygiene task. Flossing first can also reveal areas that need a bit more attention from brushing if you suddenly encounter heavy particle debris or you notice a little bit of blood on the floss. And, by flossing first you may be able to clear away plaque from your tooth enamel so that it can more readily absorb the fluoride in toothpaste.
One last thing about flossing first: if it’s your least favorite task of the two and you’re of the “Do the Unpleasant Thing First” philosophy, you may want to perform it before brushing. You’re less likely to skip it if you’ve already brushed.
On the other hand, flossing first could get you into the middle of a lot sticky plaque that can gum up your floss. Brushing first removes a good portion of plaque, which can then make flossing a little easier. With the bulk of the plaque gone by the time you floss, you’ll not only avoid a sticky mess on your floss you’ll also have less chance of simply moving the plaque around with the floss if there’s a large mass of it present.
It really comes down to which way you prefer. So, brush first, floss last or vice-versa—but do perform both tasks. The one-two punch of these important hygiene habits will greatly increase your chances for maintaining a healthy mouth.
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.
