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.

Cancer treatment can be an all-out battle with intense side effects for your entire body. One particular area that can suffer is your mouth.
Chemotherapy and radiation target and destroy cancer cells, which can lead to non-cancerous cells caught in the crossfire and also destroyed. The salivary glands in the mouth are prone to such damage, which could greatly impact your ability to ward off dental disease.
Saliva, what salivary glands produce, plays a major role in oral health. The bodily fluid disseminates antibodies throughout the mouth that fight disease-causing bacteria. It also neutralizes acid, which can erode tooth enamel, and helps restore lost minerals to the enamel.
If the salivary glands become damaged, however, they may produce less saliva and create a condition called xerostomia or “dry mouth.” This is a common occurrence for cancer patients, which can rob them of saliva’s benefits and make them more susceptible to tooth decay or periodontal (gum) disease. The end result could be tooth loss.
There are things you and your dentist can do to prevent this. First, have a complete dental checkup before undergoing cancer treatment. If at all possible have any necessary dental work undertaken (with adequate recovery time afterward) before beginning chemo or radiation. Your dentist and oncologist (cancer specialist) may need to coordinate any planned dental work.
You should also practice daily oral hygiene with brushing and flossing, along with keeping up your regular dental cleanings. This will prevent the buildup on teeth of bacterial plaque, which in turn will reduce your chances for dental disease. Your dentist may also prescribe antibacterial as well as fluoride mouth rinses to help limit the growth of oral bacteria.
To minimize dry mouth, increase your water consumption as much as possible. You may also use saliva boosters like xylitol, an alcohol-based sweetener found in many gums or mints that promotes salivation (it also deters oral bacterial growth).
And don’t forget to maintain a healthy diet, which will not only benefit your stamina during cancer treatment but can also help you maintain better dental health. Providing good care for your mouth during this trying time will help ensure your teeth and gums stay as healthy as possible.

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.
Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.
Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.
There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.
A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.
If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.
