Protecting your children is one of your most important roles as a parent or caregiver. Dental sealants are one way you can protect your children's teeth from the ravages of tooth decay, drilling and fillings — and they can be applied simply, comfortably and quickly right here in our office.

What is a dental sealant?

A dental sealant is a thin, plastic film that is painted onto the tiny grooves on the chewing surfaces of the back teeth (usually the premolars and molars) to prevent caries (cavities) and tooth decay. And by allowing us to use sealants to seal these little nooks and crannies where your child's toothbrush can't reach, you will dramatically reduce their chances for developing tooth decay. This one, simple and quick office visit could save you both money and time with fewer dental visits and healthier, cavity-free teeth.

So will sealants guarantee no (or no more) cavities?

No, just like life, there are few guarantees. Your child's oral hygiene, regular dental visits, fluoride, sugar consumption and genetics are the other important factors that will determine to what degree your child experiences tooth decay. However, research shows that pit and fissure (chewing surface) decay accounts for approximately 43% of all decayed surfaces in children aged 6 to 7, even though the chewing surfaces (of the back or posterior teeth) constitute only 14% of the tooth surfaces at risk. This demonstrates the vulnerability of the chewing surfaces of the posterior teeth to decay. By placing a protective seal over the areas of teeth at risk, you can effectively and proactively protect your children's teeth.

How long do sealants last?

Research has shown that some sealants can last up to 10 years. However, if you opt for sealants for your children's teeth, we will closely monitor them with each office visit to ensure that they are still doing their job. As needed, we can apply more sealant.

Temporomandibular Disorder (TMD), which was formerly known as Temporomandibular Joint Disorder (TMJ), is a condition that is unusual in that it frequently is quite hard to diagnose, because it often mimics many other conditions. For this reason, many healthcare professionals refer to it as “the great imposter.” The condition arises when there are problems inside the temporomandibular joint and the muscles that attach to it causing pain. The pain is most often due to muscle spasm, thereby limiting the ability to open and close the jaw and to function normally. TMD can impact anyone and has a wide range of similar symptoms.

One of the common causes of TMD is stress, and it may manifest itself through clenching or grinding of teeth while awake or asleep. These habits are often completely subconscious until pointed out by a dental professional or sleeping partner. With stress-induced TMD, the pain often comes and goes in cycles. In other words, it may be present when you are stressed, seem to disappear for a while, and then reappear when you are stressed again. Another cause of TMD can be from an injury or trauma, such as a blow to the jaw. However, regardless of the cause of TMD, the pain is real and needs to be treated properly.

If you feel that you might have TMD, please let us know so that we can address your concerns, starting with a full history and conducting a thorough examination. Or if you are in constant or severe pain, contact us immediately to schedule an appointment. You can learn more about the signs, symptoms, and treatment options for TMD by reading “TMD — Understanding The Great Imposter.”

When you begin a smile makeover in our office, you are embarking on an exciting partnership with my laboratory technician and me. You should be full of excitement and anticipation — if you have been dissatisfied with your current smile, and you have great expectations for the results of this project. You will really like what you see in your mirror.

Being completely satisfied with your new look depends upon successful communication — between you and me and also between my dental lab technician and me. As you might expect, your perceptions of how your teeth appear are different from a dentist's perceptions. My education leads me to think of factors that untrained individuals probably won't consider, such as crown (tooth) length, midlines (how the teeth line up with other facial features) and the distance from gum to lip.

It is helpful to be able to describe what you like and don't like about your current smile, and what changes you would like to see. Using visual aids is a good idea. Bring photos and magazine illustrations to show what you have in mind. (Remember that we cannot make you look exactly like a celebrity or anyone else. The pictures are guidelines.)

Things to think about:

• The color, size, shape, alignment and spacing of your teeth.
• How much of your teeth and gum tissues show when your lips are relaxed and when you smile.
• Tooth color: bright “Hollywood” white or more natural looking off-white.

Your makeover is more likely to meet your expectations if you get an advanced view of the results. Computer imaging is one way to do this. Another is for us to make a mock-up of the proposed dental work in tooth-colored wax on models of your mouth.

Finally, a “Provisional Restoration” can be used as a test to make sure that what I envision is also what you, the patient, want to see. A provisional restoration, made from temporary materials, gives you a chance to test out the changes and make sure they work for you — that they not only look good, but they are also functional in terms of biting, chewing, speech, and gum health.

If the provisional restoration works, it is used as a blueprint to make durable and long lasting porcelains in the same design. We will take impressions of the provisional restoration and communicate the relevant information to a dental laboratory technician, who will make the final porcelain tooth replicas for your new smile.

Competent communication and a provisional restoration will put you on track to meet your expectations and obtain the most aesthetic and functional result in your Smile Makeover.

Dentistry has ventured into the new area of sleep medicine by helping snorers — and their exasperated sleeping partners — with custom-made anti-snoring devices. These oral appliances, which resemble orthodontic retainers or sports mouthguards, keep the snorer's airway clear and the bedroom quiet. To see how they work, you have to understand the mechanics of snoring.

Snoring occurs when the upper airway (back of the throat) becomes blocked by the tongue or other soft-tissue structures, such as large tonsils or a long soft palate. The vibrating of these obstacles creates the sound we call snoring.

Snoring is often worse when sleeping on one's back because that position encourages the lower jaw to fall back and the tongue to close off the airway. This is where Oral Appliance Therapy comes in. These custom-fitted devices are designed to keep the upper airway open during sleep by pulling the lower jaw forward, which in turn brings the tongue away from the throat. Dentists, and our office in particular, are the only source for Oral Appliance Therapy.

People who snore should have a thorough examination to rule out Obstructive Sleep Apnea (OSA), a potentially dangerous condition in which airflow can be cut off completely for 10 or more seconds (“a” – without; “pnea” – breath), reducing blood-oxygen levels. Chronic, loud snoring is a common finding with OSA.

Please remember that sleep is an integral part of health and well-being. In fact, we spend about a third of our lives doing it. If you are snoring or have any sleep-related breathing disorders that are waking you or your bed partner, be sure to tell our office. There are plenty of examples of the havoc wreaked by sleep-deprived individuals. Remember the Exxon Valdez?

If you have any questions about Oral Appliance Therapy, please contact us or schedule an appointment for a consultation.

Here's an interesting tidbit of information on Wheel of Fortune host Vanna White: like many people, she grinds her teeth at night. In a detailed interview with Dear Doctor magazine, Vanna explained how she had to replace a filling in a back tooth several times because of her grinding habit. Eventually, she had her dentist make her a nightguard to protect her famous smile.

“I really try to sleep with it every night,” Vanna told the magazine. “I try to keep it on my nightstand so when I go to bed, I remember to put it in. Or I will put it by my toothbrush so I can put it in after brushing my teeth at night.”

The habit of teeth grinding or clenching is often associated with stress and/or sleep deprivation. It is referred to as “parafunctional” (“para” – outside, “function” – normal), meaning it can generate biting forces well outside the normal range — perhaps 10 times normal. This excessive force can affect many areas of the oral system. Teeth may become worn, chipped or loose; jaw joints or muscles can go into spasm; and some grinders (or “bruxers” as they are also called) may even experience discomfort of the head, ears, neck or back. Many times, a person with a grinding habit does not become aware of it until it is pointed out by a sleep partner or dental professional.

Like Vanna White's dentist, we often recommend a nightguard to those with nocturnal bruxing habits. It is made of a very thin, wear-resistant plastic that fits over the biting surfaces of the upper teeth only. The lower teeth are then free to glide or skate over the guard, which prevents them from biting into the upper teeth. Some people wear their guards during the day if they tend to clench their teeth when under stress.

If you are concerned about teeth grinding or interested in learning more about nightguards, please contact us today to schedule an appointment for a consultation.
