The braces are finally off! But to keep your new, straighter smile you'll need to wear a retainer for some time. That's because the same structural mechanism used to move your teeth could undo what we've just accomplished.
That mechanism resides in an elastic tissue called the periodontal ligament that lies between the teeth and the bone and attaches to both with tiny fibers. While the ligament holds the teeth securely in place, it also allows for slight movement in response to bite changes. Braces "pull" the teeth in the desired new direction, and the ligament responds.
But with that pressure gone after the braces' removal, a kind of "muscle memory" can set in that moves the teeth back towards their original positions. A retainer, a dental appliance worn on the teeth, exerts just enough pressure to "retain" or keep the teeth from regressing.
Retainers are effective, but the most common type has a feature that poses potential problems: it can be removed by the wearer. Because of this, less disciplined patients might be tempted not to wear their retainer as directed. There's also a higher risk of losing one and incurring additional cost to replace it.
But there is another type, the bonded retainer, which stays permanently in the mouth until removed by an orthodontist. It's composed of a thin piece of metal that's firmly attached to the back of the teeth with dental composite material. Not only does a bonded retainer solve the problems mentioned before, it also can't be seen from the outside like a removable retainer.
A bonded retainer does have one disadvantage: because it can't be removed, it can obstruct the teeth during brushing and flossing and require more effort. You won't have as much difficulty with a removable retainer keeping teeth and gums clean. You can overcome this disadvantage, though, with specialized tools like a water flosser or a floss threader to make hygiene easier.
To choose which type of retainer is best for you or your family member, have a talk with your orthodontist. And if you choose a bonded retainer and later have it removed, be sure to switch immediately to a removable one if your orthodontist advises. With either retainer, you'll be able to preserve that hard-earned smile for years to come.

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.
For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.
Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.
That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.
If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.
With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.
Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
