You may be familiar with a dental implant used to replace a single tooth — but implant technology can do much more. Implants can also support other restorations including total teeth replacement on a jaw.
The reason they're so versatile is because implants replace the tooth root as well as the visible crown. We use a metal post, usually made of titanium, which we surgically implant in the jawbone as a root substitute. Because of a special affinity with titanium, bone around the implant grows and adheres to it and creates a durable bond.
With a single tooth replacement (the implant's original purpose when they were introduced in the 1980s) we attach a life-like porcelain crown to the individual titanium post. But with their continuing development we've adapted implants for other applications, like using a few strategically-placed implants as a stable platform for removable dentures or fixed bridges.
We're now able to use implants to support a full prosthetic (false) dental arch. Though similar in appearance to a removable denture, this particular prosthesis is permanently joined to the supporting implants with retaining screws.
Of course, the application requires careful pre-planning, which includes making sure you have enough healthy bone to support the implants. We'll also need to determine how many implants you'll need (usually four to six for this application) and create a surgical guide to place them in the best location for supporting the prosthesis. A dental technician will then create the prosthesis to match your jaw ridge contours and facial structure.
Using implants this way has a benefit other types of restorations can't provide: they may help stop future bone loss. The jawbone life cycle depends on stimulation from the attached tooth as you bite and chew — stimulation that ends when you lose the tooth. Traditional dentures and other restorations can't replicate that stimulation. Implants, on the other hand, directly encourage bone growth and can stop gradual bone loss.
If you need some form of total teeth replacement, consider one supported by implants. You may find they'll provide an excellent long-term solution to both function and appearance.
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.

Sometimes it's the little things that can be most annoying. Those occasional small sores that pop up on the inside of your mouth are a case in point. Although in most instances they won't last long and aren't anything to be alarmed about, they can still cause you some discomfort.
These small sores are called aphthous ulcers or more commonly “canker sores.” They are breaks in the skin or mucosa, the inner lining of the mouth, and occur most often on the inside cheeks, lips, tongue and occasionally on the soft palate at the back of the throat. They usually appear round with a yellow-gray center and an intensely red outer ring or "halo."
Canker sores often appear during periods of high stress or because of minor trauma, and usually last for a week or two. They often have a tingling pain that can be aggravated when you eat and drink acidic or spicy foods and beverages. About 20 to 25% of people have a form known as recurrent aphthous stomatitis (mouth inflammation) that occurs regularly with multiple sores and heightened pain.
It's possible to manage the discomfort of minor, occasional bouts with a number of over-the-counter products that cover the sore to protect it and boost healing, with some providing a numbing agent for temporary pain relief. For more serious outbreaks we can also prescribe topical steroids in gels or rinses, injections or other medications.
While canker sores don't represent a health danger, there are instances where you should take outbreaks more seriously: if a sore hasn't healed after two weeks; if you've noticed an increase in pain, frequency or duration of outbreaks; or if you're never without a sore. In these cases we may need to biopsy some of the tissue (and possibly run some blood tests) to ensure they're not pre-cancerous or cancerous.
In any event, we can work with you to reduce your symptoms and help the sores heal quickly. This particular “little thing” in life doesn't have to stress you out.
