Tooth decay and other oral diseases aren’t the only dangers your teeth face — accidental injuries also pose a risk. Fortunately, much can be done to save injured teeth, if you act quickly.
Dental injuries where part of the enamel crown has chipped off are the most common. Even if only one tooth appears damaged, adjacent teeth and bone might also have been damaged internally. Most chip injuries can be repaired either by reattaching the broken crown or with a tooth-colored filling or veneer. If the damage has extended into the inner tooth pulp then a root canal treatment might ultimately be necessary.
Teeth that have been knocked loose from normal alignment (dislodged) or where the entire tooth with its root has separated from the socket (avulsed) are rare but severe when they occur. It’s imperative to see a dentist as soon as possible — even more than five minutes’ of elapsed time can drastically reduce the tooth’s survivability. Dislodged teeth are usually splinted to adjacent teeth for several weeks; we would then carefully monitor the healing process and intervene with endodontic treatment (focused on the tooth’s interior) should something unfavorable occur.
With the possible exception of a primary (baby) tooth, an avulsed tooth should be placed back in the socket as soon as possible. This can be done by someone on scene, as long as the tooth is handled gently, the root not touched, and the tooth rinsed with cold, clean water if it has become dirty. If no one is available to do this, the tooth should be placed in milk to avoid drying out the root, and the patient and tooth transported to a dentist immediately. Once in the socket, the treatment is similar as for a dislodged tooth with splinting and careful watching.
The damaged tooth should be checked regularly. Your body’s defense mechanism could still reject it, so there’s a danger the root could be eaten away, or resorbed. Some forms of resorption can’t be treated — the aim then is to preserve the natural tooth for as long as possible, and then replace it with a life-like restoration to regain form and function.

What if you had orthodontic treatments to enhance your smile — and nobody knew about it until it was all done?
That (almost) happened to British singer, cover girl and television personality Cheryl Cole. Since her big break in 2002, on the British reality show Popstars: The Rivals, Cole has had a successful music career, taken turns judging both the British and American versions of The X Factor, and graced the covers of fashion magazines like Elle and Harpers Bazaar.
And somewhere along the way, Cole wore an orthodontic appliance. It very nearly went undetected… until a colleague spilled the beans. That’s when Cole was forced to divulge her secret: For a period of time, she had been wearing clear aligners on her teeth. Until her frenemy’s revelation, only a few people knew — but when you compare the before-and-after pictures, the difference in her smile is clear.
So what exactly are clear aligners? Essentially, they consist of a series of thin plastic trays that are worn over the teeth for 22 hours each day. The trays are custom-made from a computerized model of an individual’s mouth. Each tray is designed to move the teeth a small amount, and each is worn for two weeks before moving on to the next in the series. When the whole series is complete, the teeth will have shifted into their new (and better aligned) positions.
Besides being virtually unnoticeable, aligners are easy to remove. This makes it easy to keep the teeth clean — and can come in handy for important occasions (like cover-photo shoots and acceptance speeches). But don’t remove them too frequently, or they won’t work as planned. If that’s a possibility (with teens, for example), aligners are available with “compliance indicators” to ensure they’re being worn as often as they should be. They can also be made with special tabs to hold a place for teeth that haven’t fully erupted (come in) yet — another feature that’s handy for teens.
So if you need orthodontic work but prefer to stay “under the radar,” ask us whether clear aligners could be right for you. Cheryl Cole did… and the results gave her something more to smile about.

One of your teeth's best defenses against tooth decay is its hard, outer layer made of a mineral-rich substance known as enamel. This great protector, however, has an enemy — acid — from the foods and drinks we consume as well as the acid byproducts from bacterial plaque. A high acidic level in the mouth could lead to the complete erosion of enamel, leaving teeth more susceptible to decay.
When the acid level in the mouth rises, calcium and other minerals in enamel become soft and begin to slough off, a process called de-mineralization. But the body can reverse this process with the help of saliva, which can neutralize acid. Saliva also contains calcium that can bind to the tooth surface and help replace what was lost during de-mineralization — a process known as re-mineralization. Saliva can normally accomplish this in thirty minutes to an hour after eating.
Unfortunately, saliva's neutralizing power can be overwhelmed when there is too much acid present. This occurs when we ingest substances like sodas or sports drinks that are high in citric acid. Many of these same beverages also have a high buffering capacity that slows the neutralizing effect of saliva. Ironically, we can also interrupt re-mineralization if we brush our teeth too quickly after eating or drinking something acidic. The enamel has been softened by the acid and when we brush before re-mineralization we can actually brush away some of the enamel.
There are some steps you can take to help this natural process for maintaining a healthy pH balance in the mouth. First, limit your intake of acidic foods and beverages. Drink water for rehydration, or at least acidic beverages enriched with calcium. If you do drink an acidic beverage use a straw to reduce acid contact with teeth, try not to swish it around in your mouth, and try to drink it during mealtime. Finally, wait 30 to 60 minutes before brushing your teeth after eating or drinking something acidic.
Tooth enamel is a key component in maintaining healthy teeth. Protecting this prime defense against decay will pay you dividends for many years to come.
