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.

Like most people, you’ve no doubt experienced occasional dry mouth as when you’re thirsty or just waking from sleep. These are normal occurrences that usually don’t last long.
But xerostomia or chronic dry mouth is another matter. Not only is this continual lack of adequate saliva uncomfortable, it could increase your risk for tooth decay or periodontal (gum) disease.
What’s more, chronic dry mouth can have a number of causes. Here are 3 common causes and what you can do about them.
Inadequate fluid intake. While this may seem obvious, it’s still common—you’re simply not consuming enough water. This deprives the salivary glands of adequate fluid to produce the necessary amount of saliva. If you’re regularly thirsty, you’ll need to increase the amount of water you drink during the day.
Medications. More than 500 drugs, both over-the-counter and prescription, can cause dry mouth as a side effect. This is one reason why older adults, who on average take more medications, have increased problems with dry mouth. There are some things you can do: first, talk with your healthcare provider about alternative drugs for your condition that are less likely to cause dry mouth; drink more water right before taking your medication and right afterward; and increase your daily intake of water.
Diseases and treatments. Some systemic diseases like diabetes or Parkinson’s disease can lead to xerostomia. Autoimmune conditions are especially problematic because the body may turn on its own tissues, the salivary glands being a common target. Radiation or chemotherapy treatments can also damage the glands and lead to decreased saliva production. If you have such a condition, talk with your healthcare provider about ways to protect your salivary glands.
You can also ease dry mouth symptoms with saliva boosters like xylitol gum or medications that stimulate saliva production. Limit your intake of caffeinated drinks and sugary or acidic foods. And be sure you stay diligent with your oral hygiene habits and regular dental visits to further reduce your risks of dental disease.

If you're in need of a crown to cover a damaged tooth, you have a lot of options. But before you choose, you need to know what you want. Would you be happy with an affordable, well-fitting crown that holds up well and allows you to chew comfortably? Or are you interested in a more expensive one that also provides the most attractive result?
Crowns have been a mainstay in dentistry for generations. The first were made of metals like gold or silver — durable and effective but not very attractive.
In time, a ceramic material known as dental porcelain began to make its appearance in crowns. Dental porcelain could be fashioned to resemble the color and texture of natural teeth, but it had a significant drawback: it could be brittle and subject to shattering under chewing pressure.
This problem was somewhat addressed with the innovation of a crown with a metal substructure fused with an outer layer of porcelain. These porcelain-fused-to-metal (PFM) crowns combined the best advantages of both materials: strength and life-likeness. Up until around the mid-2000s, PFM made up over 80% of crowns.
But later porcelains continued to improve in strength, beginning in 1993 with the introduction of a Lucite-reinforced material. Newer formulations like lithium disilicate or zirconium oxide (now considered the strongest porcelain) have made all-porcelain crowns a viable option. Today, an estimated 60% of new crowns are all-porcelain.
From an appearance standpoint, all-porcelain crowns achieve the best results. The most realistic crown can be costly — not because of the material but the level of artistry required. A skilled dental technician will spend several hours, including brushing on as many as fifteen coats of liquid porcelain to the crown, to achieve the most life-like outcome. Your insurance plan, if you have one, will most likely not pay as high a percentage for that type of crown.
In the end, it's your decision as to what type of crown you wish to have. We'll help you weigh your options and decide what's best for you and your budget.
