If you've suddenly noticed your smile looking more “toothy,” you may have a problem with your gums. They may have lost their normal attachment to your tooth and begun to shrink back — or recede.
Millions of people have some form of gum recession. The most common cause is periodontal (gum) disease, but it's not the only one. You may be more susceptible to gum recession because of heredity — you have thin gum tissues passed down to you from your parents. You may also be brushing too hard and too often and have damaged your gums.
Healthy gums play an important role in dental health. The crown, the tooth's visible part, is covered with a hard, protective shell called enamel. As the enamel ends near where the root begins, the gums take over, forming a tight band around the tooth to protect the roots from bacteria and acid.
Receding gums expose these areas of the tooth meant to be covered. This can lead to another tell-tale sign — tooth sensitivity. You begin to notice pain and discomfort while you consume hot or cold foods. And because it leaves your teeth and gums looking much less attractive, it can affect your confidence to smile.
Fortunately, though, we can help restore receded gums. If you have gum disease, it's imperative we treat it as early as possible. We do this by removing plaque, a thin film of bacteria and food particles that triggers the infection. We use special techniques and hand instruments to remove plaque and calculus (hardened plaque deposits) from all tooth surfaces including along the roots.
Gum disease treatment can help stop and even reverse gum recession. In some cases, though, the recession may have advanced too far. If so, we may need to consider surgically grafting donor tissue to the recessed areas. Depending on the site and extent of recession, this can be a very involved procedure requiring microscopic techniques.
The best approach, though, is to take care of your gums now. Daily brushing and flossing removes harmful plaque; regular dental visits take cleaning a step further and also give us an opportunity to detect disease early. By looking out for your gums now you might be able to avoid gum recession in the future.
In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

A root canal treatment is a highly effective way to save a deeply decayed tooth. Sometimes, though, complications make it difficult or even impossible to perform the traditional procedure. In those cases, we may need to use a different option.
Tooth decay becomes an imminent threat to a tooth's survival if it works its way into the pulp, the innermost layer of a tooth. It's only a short advancement from there into the roots by way of the root canals.
In a typical root canal treatment, we access the pulp by drilling a small hole in the biting surface of a back tooth or the back side of a front tooth. We remove all the tissue within the pulp and fill it and the root canals with a special filling to prevent re-infection. After sealing the access hole, we cap the tooth with a crown to further protect it.
Although root canal treatments have a high success rate, re-infection can still occur. Often, a second root canal will save the tooth from the new infection.
In some cases, though, using the traditional procedure might do more harm than good. It's possible we may find extra canals previously undetected branching out from the primary canal at the root end. Canals can calcify and narrow, making them extremely difficult to fill. Subsequent dental work may also prove troublesome: we would have to take the restoration apart, which could further weaken the tooth.
The alternative is a procedure known as an apicoectomy. Instead of accessing the pulp through the crown, we access the root end through the gum tissue. We then focus on removing infected tissue at the tooth's root end, along with a tiny amount of the root tip. We then place a small filling at the end of the root canal (essentially plugging it up) to prevent further infection. We may also perform grafting to encourage bone growth in any voids left by the procedure.
Endodontists, specialists in root canals, have the advanced training and specialized equipment to perform an apicoectomy. With their expertise, they may be able to save your tooth with this specialized procedure when a root canal treatment won't work.
