There are many new and exciting ways now to transform an unattractive smile into one you'll be confident to display. But not all “smile makeover” techniques are new — one in particular has been around for generations: using braces to correct crooked teeth.
Braces have improved the smiles (and also dental health) for millions of people. But as commonplace this orthodontic treatment is, it wouldn't work at all if a natural mechanism for moving teeth didn't already exist. Braces “partner” with this mechanism to move teeth to better positions.
The jawbone doesn't actually hold teeth in place — that's the job of an elastic gum tissue between the teeth and bone called the periodontal ligament. Tiny fibers extending from the ligament attach to the teeth on one side and to the bone on the other. In addition to securing them, the dynamic, moldable nature of the ligament allows teeth to move incrementally in response to forces applied against them.
To us, the teeth feel quite stationary (if they don't, that's a problem!). That's because there's sufficient length of the tooth roots that are surrounded by bone, periodontal ligament and gum tissue. But when pressure is applied against the teeth, the periodontal ligament forms both osteoblasts (bone-forming cells) and osteoclasts (bone-resorbing cells) causing the bone to remodel. This allows the teeth to move to a new position.
Braces take advantage of this in a controlled manner. The orthodontist bonds brackets to the outside face of the teeth through which they pass a thin metal wire. They attach the ends of the wire to the brackets (braces), usually on the back teeth. By using the tension placed in the wire, the orthodontist can control the gradual movement of teeth to achieve proper function and aesthetics. The orthodontist continues to monitor the treatment progress, while making periodic adjustments to the tension.
It takes time, but through this marvelous interplay between nature and dental science you'll gain a more healthy and beautiful smile.

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.
