Waiting is part of life for a teenager: waiting to get a driver’s license, to graduate high school or to leave home and stretch their wings. A teenager with lost teeth may also need to wait until they’re older to obtain dental implants.
The reason arises from the differences in how implants and natural teeth attach to the jaw. Although natural teeth may seem rigidly set in the bone, they’re actually held in place by an elastic tissue between them and the bone known as the periodontal ligament. Tiny filaments that attach to the teeth on one side and the bone on the other hold the teeth in place, but also allow the teeth to move gradually in response to mouth changes.
A titanium implant post doesn’t have this relationship with the periodontal ligament — it’s attached directly to the jaw bone. Over time the bone, which has a special affinity with titanium, grows and adheres to it to form a durable bond without an attachment to the periodontal ligament. Because of this the implant can’t move like a natural tooth.
This is extremely important for implant placement because the jaws in particular won’t fully develop in most people until their late teens or early twenties: the upper jaw in particular will tend to grow out and down. Natural teeth accommodate to these changes, but the implant can’t — it will appear to retreat into the jaw. The gum tissues surrounding the implant also won’t conform to the continuing growth and may appear receded.
The best approach is to choose a temporary replacement option until the jaws and other facial bone structures have finished growing. One example is a bonded bridge in which we use a bonding agent to attach a bridge of artificial teeth to teeth on either side of a missing tooth — bonding won’t permanently alter them as with a traditional bridge. Once the jaws have finished growing, we can remove the bonded bridge and install the more permanent implant.
Ask any teenager: waiting can be hard. But with dental implants, waiting until the right time will help ensure the attractive result is a permanent one.

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.
