It’s been a long road with your braces, but now they’re finally off. Hopefully the first glimpse of your new smile more than made up for the time and effort they required.
But while braces removal is a big milestone, it’s not the end of your treatment—not, that is, if you want to keep that new smile! You’ll now need to wear an appliance called a retainer for a few years or, in some cases, from now on.
Orthodontic retainers are a must after braces for the same reason braces work in the first place—your teeth can move. While the teeth attach to the jawbone via the roots, they’re firmly held in place by an elastic gum tissue network called the periodontal ligament. This tough but elastic tissue lies between the teeth and gums and attaches securely to both with tiny fibers.
While the ligament provides stability, it’s also dynamic—constantly remodeling to allow the teeth to move in response to biting pressure and other mouth factors. Orthodontists use this mechanism when moving teeth to better positions. The braces apply pressure on the teeth in the desired direction and the periodontal ligament responds as the teeth move.
Afterward, however, the ligament can still retain a kind of “muscle memory” for a time of the teeth’s old positions. Free of the pressure once supplied by the braces the teeth have a tendency, especially early on, to “rebound” to where they were.
A retainer helps prevent this by exerting just enough pressure to “retain” the teeth in their new positions. In the beginning this may require wearing the appliance around the clock, but you may be able later to reduce wear time to just a few hours a day. Rebounding is unpredictable, so you should continue to follow your orthodontist’s recommendations on retainer wear.
Wearing a retainer may seem like a drag, but it’s absolutely essential. Being diligent about it will help ensure that the beautiful smile you and your orthodontist worked so hard to obtain stays with you for years to come.

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.

Cardiovascular disease and periodontal (gum) disease are two different conditions with their own set of symptoms and outcomes. But they do share one common element: inflammation. In fact, this otherwise normal defensive response of the body might actually create a link between them.
When tissues become damaged from disease or injury, the body triggers inflammation to isolate them from the rest of the body. This allows these tissues to heal without affecting other tissues. If inflammation becomes chronic, however, it can damage rather than protect the body.
This happens with both cardiovascular disease and gum disease. In the former, low-density lipoproteins (LDL or “bad cholesterol”) in animal fat leave behind remnants that can build up within arteries. This stimulates inflammation of the vessel’s inner linings, which accelerates hardening and increases the risk of heart attack or stroke.
With gum disease, bacteria living in a thin, built-up film of food particles on the teeth called plaque infect the gum tissues, which in turn trigger inflammation. A struggle ensures between the infection and inflammation, causing the gum tissues to weaken and detach from the teeth. Coupled with erosion of the supporting bone, the risk of tooth loss dramatically increases.
Recent research now seems to indicate the inflammatory responses from these two diseases may not occur in isolation. There is evidence that gum inflammation could aggravate inflammation in the cardiovascular system, and vice-versa. The research, though, points to some possible good news: treating inflammation in either disease could have a positive effect on the other.
Making heart-friendly lifestyle changes like losing extra weight (especially around the waist), improving nutrition, and exercising regularly can help reduce LDL and lower the risk of arterial inflammation. Likewise for your gums, daily oral hygiene and visiting the dentist at least twice a year reduces the risk for gum disease. And at the first sign of a gum infection—swollen, reddened or bleeding gums—seeking immediate treatment will stop it and reduce any occurring inflammation.
Taking steps to prevent or reduce inflammation brought on by both of these diseases could improve your health and save your life.
