RetainersTheFinalSteptoaGreatNewSmile

As soon as the braces come off, many people feel that the hard work in getting a new smile is all done. But wait! There's one critical piece of the process that remains: the orthodontic retainer. What makes this little device so important?

To understand that, let's look at how your teeth are attached, and how they may move. A tooth isn't anchored into the jaw like a screw in wood — it's joined to its bony housing by a unique, hammock-like suspension system called the periodontal (“peri” – around; “odont” – tooth) ligament. The periodontal tissues are living, constantly changing and renewing themselves.

Orthodontic appliances like braces are designed to apply just enough pressure to move the teeth slowly and steadily into new positions. As the teeth are moved, the periodontal tissue gradually re-forms around them, helping to hold them in their new locations.

But tooth, bone and gum tissues also have a “memory” which, if left alone, tends to move the teeth rapidly back to their original places. This unwanted movement gradually lessens, but it can be an issue for a long time after treatment. That's where the retainer comes in.

This little device holds the teeth steady in their new positions until the bones and ligaments have had enough time to re-form — a development that can take several months. It brings the entire process of moving the teeth to a gradual close, helps to prevent trauma and to maintain proper tooth location.

Once, all retainers were made of plastic and wire, and all were removable. These are still popular, and are usually worn 24 hours a day at first, then less often, until (after a period of time) they're only worn at night. Alternatively, in many cases a thin wire can be bonded to the inside surfaces of the front teeth. This type of retainer doesn't show, and it doesn't have to be removed.

How long will you have to wear it? It's hard to say. Teeth are kept in position not only by bone and ligament, but also by a balance of forces between the tongue, lips and cheeks. They aren't permanently fixed in place, but can move over time in a way that's unique to every person. Depending on the type of tooth movement done, we can recommend what type of retainer is right for you, and how often to wear it. Having the right retainer will help ensure you get the best result: a great new smile.

TheGapIsNoMore

This is the story of a well-known man, fearless in most respects, who was afraid of the dentist. Even though his fears had resulted in neglect and serious damage to his teeth, modern dentistry and a talented dental team were able to restore his smile to health. If you share this fear, his story may inspire you to take action.

We're talking about William Perry, former defensive lineman and fullback for the Chicago Bears. Here is a man who could fearlessly face a football squad — but not a visit to the dentist. Nicknamed “The Refrigerator” for his 380-pound massive frame, Perry played for ten years in the NFL before retiring in 1994. Since retiring he founded and operated a construction company in South Carolina in addition to making celebrity appearances.

With his celebrity in mind, a team composed of a talented restorative dentist, implant surgeon, and lab technician agreed to give “The Fridge” a makeover. After discussing modern technology and virtually pain-free dentistry with him, they managed to overcome Perry's fears. “I had been in constant pain for many years and I neglected myself, not having had any dental care for over 20 years, not even emergency care. Unfortunately, as I grew older my teeth started to get loose,” Perry told an interviewer. He had lost many teeth and became known for his gap-toothed smile.

Perry had severe gum disease and many of his remaining teeth were loose. In the past his only option would have been a full set of dentures. But his new dental team was able to place dental implants (permanent tooth replacements) supporting fixed bridges. In most cases dental bridges are attached to healthy teeth, but in Perry's case the implants served as anchors for the bridges. They also stabilized his jawbone, which would otherwise “resorb” or melt away after his teeth were lost. This is important because it helps preserve the contours of his face.

After careful planning “The Fridge” had eight dental implants placed in his upper jaw and seven in his lower. The final bridgework was completed four months later. It turned out that even though the gap between his teeth had become his trademark, “the Fridge” never really liked it. He was thrilled with his new smile.

Even if you have some fears, don't hesitate to follow Perry's example and make an appointment with us for a consultation about dental implants, smile makeovers, or bridgework.
