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.

If you're the principal caregiver for an older person, you may have already faced age-related health challenges with them. Good preventive care, however, can ease the impact of health problems. This is especially true for their teeth and gums: with your support you're loved one can have fewer dental problems and enjoy better health overall.
Here are a number of things you should focus on to protect an older person's dental health.
Hygiene difficulties. With increased risk of arthritis and similar joint problems, older people may find brushing and flossing more difficult. You can help by modifying their toothbrush handles with a tennis ball or bicycle grip for an easier hold, or switch them to an electric toothbrush. A water flosser, a device that uses a pressurized water spray to remove plaque, may also be easier for them to use than thread flossing.
Dry mouth. Xerostomia, chronic dry mouth, is more prevalent among older populations. Dry mouth can cause more than discomfort—with less acid-neutralizing saliva available in the mouth, the risk for dental diseases like tooth decay or periodontal (gum) disease can soar. To improve their saliva flow, talk with their doctors about alternative medications that cause less dry mouth; and encourage your loved one to drink more water and use products that help boost saliva flow.
Dentures. If your older person wears dentures, be sure these appliances are being cleaned and maintained daily to maximize their function and reduce disease-causing bacteria. You should also have their dentures fit-tested regularly—chronic jawbone loss, something dentures can't prevent, can loosen denture fit over time. Their dentures may need to be relined or eventually replaced to ensure continuing proper fit and function.
Osteoporosis. This common disease in older people weakens bone structure. It's often treated with bisphosphonates, a class of drugs that while slowing the effects of osteoporosis can cause complications after certain dental procedures. It's a good idea, then, for an older person to undergo any needed dental work before they go on osteoporosis medication.
Keep alert also for any signs of dental disease like unusual spots on the teeth or swollen or bleeding gums. Visiting the dentist for these and regular dental cleanings, checkups and oral cancer screenings could prevent many teeth and gum problems.

Ever since childhood, when her career as a model and actress took off, Brooke Shields has enjoyed worldwide recognition — through advertisements for designer jeans, appearances on The Muppet Show, and starring roles in big-screen films. But not long ago, that familiar face was spotted in an unusual place: wearing a nasal anesthesia mask at the dentist's office. In fact, Shields posted the photo to her own Instagram account, with the caption “More dental surgery! I grind my teeth!” And judging by the number of comments the post received, she's far from alone.
In fact, researchers estimate that around one in ten adults have dental issues that stem from teeth grinding, which is also called bruxism. (Many children also grind their teeth, but it rarely causes serious problems, and is often outgrown.) About half of the people who are teeth grinders report problems like persistent headaches, jaw tenderness and sore teeth. Bruxism may also result in excessive tooth wear, and may damage dental work like crowns and bridges; in severe cases, loosened or fractured teeth have been reported.
Researchers have been studying teeth grinding for many years; their findings seem to indicate that it has no single cause. However, there are a number of factors that play a significant role in this condition. One is the anatomy of the jaw itself, and the effect of worn or misaligned teeth on the bite. Another factor relates to changes in brain activity that occur during the sleep cycle. In fact, nocturnal (nighttime) bruxism is now classified as a sleep-related movement disorder. Still other factors, such as the use of tobacco, alcohol and drugs, and a high level of stress or anxiety, can make an individual more likely to experience bruxism.
What can be done for people whose teeth grinding is causing problems? Since this condition may have many causes, a number of different treatments are available. Successful management of bruxism often begins by striving to eliminate the factors that may cause problems — for example, making lifestyle changes to improve your health, creating a soothing nighttime environment, and trying stress-reduction techniques; these may include anything from warm baths and soft music at bedtime, to meditation and mindfulness exercises.
Several dental treatments are also available, including a custom-made occlusal guard (night guard) that can keep your teeth from being damaged by grinding. In some cases, a bite adjustment may also be recommended: In this procedure, a small amount of enamel is removed from a tooth to change the way it contacts the opposite tooth, thereby lessening the biting force on it. More invasive techniques (such as surgery) are rarely needed.
A little tooth grinding once in a while can be a normal response to stress; in fact, becoming aware of the condition is often the first step to controlling it. But if you begin to notice issues that could stem from bruxism — or if the loud grinding sounds cause problems for your sleeping partner — it may be time to contact us or schedule an appointment.
