Radiographic (x-ray) images are an indispensible diagnostic tool in dentistry. One of the most routine and useful types of x-rays dentists take is the so-called bitewing. Here are some things you may want to know about this common diagnostic procedure.
What are bitewing x-rays?
Bitewings reveal the presence and extent of decay in the back teeth, specifically in areas where adjacent teeth touch each other. Unlike other areas of the teeth, these contacting surfaces between adjacent teeth can’t be examined visually. Bitewings can also show areas of bone loss around teeth — a sign of periodontal disease; however, they are not taken for that purpose because bitewings will not show the complete root surface that is surrounded by bone.
Why are they called that?
The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.
How often do I need them?
This is determined on a case-by-case basis, with the goal of not exposing you to any more radiation than necessary — even the minimal amount found in a series of bitewing x-rays. Your individual susceptibility to caries (tooth decay) and personal dental history will play a major role in determining how frequently you need radiographic examination — and, for that matter, how often you need to come in for routine cleanings and exams.
Are they safe?
The safety of bitewing x-rays is best illustrated with a comparison to the regular daily radiation exposure we get every day from environmental sources, which is about 0.01 millisieverts — the unit of measure we use for radiation. A series of 4 bitewing x-rays exposes you to 0.004 millisieverts of radiation — less than half of the daily exposure. Undetected tooth decay, which can spread quickly through the softer inner layers of teeth, is considered much more dangerous!
If a bitewing x-ray shows that there is tooth decay, what happens next?
If the cavity is very small, we may be able to treat it during the same appointment. If not, we will make a separate appointment to make sure it is taken care of promptly. The sooner tooth decay is treated, the better!
Like the rest of healthcare, antibiotics have transformed dentistry. Advanced oral infections that once eluded successful treatment are routinely stopped with the use of these “wonder drugs.” But their overuse over the years has given rise to dangerous “superbugs” resistant to many antibiotics.
Antibiotics are one of the 20th Century's most significant healthcare achievements. Drugs like penicillin played a major role ending the global threat of tuberculosis, cholera and bacterial meningitis. Over the last few decades, more antibiotics have been developed to defend against an even wider array of bacterial dangers.
But along the way doctors and dentists began prescribing antibiotics for all manner of illnesses including viral infections like colds or flu for which they're less effective. They've also been increasingly used as a preventive measure, including inclusion in animal feed to fight disease.
But our tiny biological nemeses are adaptable. As bacterial strains come in contact with greater amounts of antibiotics, individual bacterium that survive transmit their resistance to subsequent generations. This can produce new strains like Staphylococcus aureus (MRSA) that are resistant to methicillin and other common antibiotics that once contained them.
There's deep concern that these new resistant strains, often recent incarnations of old diseases once thought defeated, will lead to higher rates of sickness and death. Increasing resistance could also make common procedures like those performed by dentists and oral surgeons, much riskier to undertake.
To combat this, pharmaceutical companies are racing to create new drugs to compensate. Recently, they've received an encouraging sign of hope in this battle from an unlikely source: viruses. Researchers in Tel Aviv, Israel have discovered an antagonistic protein to bacteria among a group of viruses called bacteriophages. The protein, injected into a bacterium, commandeers the cell's DNA function to aid virus reproduction, which kills the host.
In the words of one researcher, this makes these particular “enemy of our enemy” viruses our “friend.” Although the discovery is still a long way from practical use in antibiotics, harnessing it in future drug versions could help pack a greater punch against resistant bacteria.
In the meantime, providers and patients alike must practice and advocate for stricter protocols regarding the use of antibiotics. The viability of tomorrow's healthcare is on the line.
Do you wake up in the morning still feeling tired? Are you drowsy, irritable or have difficulty concentrating? And is your snoring habit a running joke around your household?
If you mostly answered yes, you may have obstructive sleep apnea (OSA). This condition is more than an irritation—it could also have major health implications if not addressed.
OSA occurs when the airway becomes temporarily blocked during sleep. The tongue (or other mouth structures like tonsils or the uvula) is often the cause as it relaxes and covers the back of the throat. Although you’re asleep, the brain notices the drop in oxygen and initiates arousal to unblock the airway. As this action usually only takes a few seconds, you may not fully awake every time; but because it can occur several times a night, it can rob you of the deep sleep you need for well-being.
If you’re diagnosed with OSA, your doctor may recommend continuous positive airway pressure therapy (CPAP). This treatment uses a pump device to supply continuous pressurized air through a hose connected to a face mask worn during sleep. The elevated pressure helps keep the airway open.
While this approach is quite effective, many people find wearing the equipment uncomfortable or confining, and may choose not to use it. If that describes you, a qualified dentist may be able to provide you with an alternative called oral appliance therapy (OAT).
OAT uses a custom-made plastic oral appliance you wear while you sleep. The most common snaps over the teeth and uses a hinge mechanism to move the lower jaw (and the tongue with it) forward.
OAT is recommended for people with mild to moderate OSA, or those with severe symptoms who can’t tolerate CPAP. If you’d like to see if an OAT appliance could help you, contact us for a complete oral examination. Either treatment can improve your sleep and daily lifestyle, as well as help prevent certain health issues in the future.

Actor Zac Efron has one of the top smiles in a business known for beautiful smiles. Bursting on the scene in 2006 at age 18 in High School Musical, Efron has steadily increased his range of acting roles. He recently starred as Ted Bundy on Netflix, wearing prosthetics to match the notorious serial killer's crooked teeth.
With his growing fame, Efron's attractive smile has become one of his more memorable attributes. But it wasn't always so. Before Hollywood, Efron's smile was less than perfect with small, uneven teeth and a gap between his top front teeth. Before and after pictures, though, make it quite apparent that the actor has undergone a significant smile makeover.
While fans are abuzz on the 411 regarding his dental work, Efron himself has been hush-hush about his smile transformation. We won't join the speculation: Instead, here are a few possible ways you can get a more attractive smile like Zac Efron.
Teeth whitening. A single-visit, non-invasive teeth whitening procedure can transform your dull, stained teeth into a brighter, more attractive smile. Although the effect isn't permanent, it could last a few years with a professional whitening and good oral practices. Having it done professionally also gives you more control over the level of shading you prefer—from soft natural white to dazzling Hollywood bright.
Orthodontics. Like Efron, if your teeth aren't quite in proper alignment, straightening them can make a big difference in your appearance (and your oral health as well). Braces are the tried and true method for moving teeth, but you may also be able to choose clear aligner trays, which are much less noticeable than braces. And don't worry about your age: Anyone with reasonably good dental health can undergo orthodontics.
Bonding. We may be able to correct chips and other slight tooth flaws with durable composite resins. After preparing your tooth and matching the material to your particular color, we apply it directly to your tooth in successive layers. After hardening, the unsightly defect is no more—and your smile is more attractive.
Veneers. Dental veneers are the next step up for more advanced defects. We bond these thin, custom-made layers of dental porcelain to the front of teeth to mask chips, heavy staining and slight tooth gaps. Although we often need to permanently remove a small amount of tooth enamel, veneers are still less invasive than some other restorations. And your before and after could be just as amazing as Zac Efron's.
Improving one's smile isn't reserved for stars like Zac Efron. There are ways to correct just about any dental defect, many of which don't require an A-lister's bank account. With a little dental “magic,” you could transform your smile.

You already know the basics for healthy and attractive teeth and gums: brush and floss every day; and have your teeth cleaned and checked by a dentist every six months. But there are also some lesser known things you can do to improve what you're already doing—and some of them may go against popular wisdom.
Here then are 3 counter-intuitive tips for turbo-boosting your teeth and gum health.
Avoid brushing too hard and too often. While it may not seem like it, “The more, the better” isn't necessarily a good thing when it comes to brushing your teeth. Vigorous brushing several times a day could actually damage both your teeth enamel and your gums, eventually leading to problems like sensitive teeth. So, easy does it on the brushing pressure—let the mild abrasives in your toothpaste do the work removing disease-causing dental plaque. Likewise, avoid brushing more than twice a day.
Wait on brushing right after eating. If your first instinct right after a meal is to head to the sink to brush your teeth, curb your enthusiasm. Your enamel is actually in a slightly softened state right after eating and drinking because of an increase in mouth acid (especially if you've consumed sodas, sports drinks or juices). Saliva restores the mouth's pH balance and helps remineralize enamel in about an hour. If you brush before then, you could be sloughing off microscopic bits of enamel—an eventual problem if this is a regular habit.
Stop snack “grazing.” If you're one of those that likes to munch on food throughout the day, you could be thwarting your overall efforts to maintain good dental health. Remember saliva? As mentioned, it effectively neutralizes acid in a few minutes. But continuous snacking maintains a constant high level of acid in the mouth—saliva has little chance to catch up. As a result, your mouth stays acidic, which can lead to higher risk of dental disease. If possible, limit your snacking to mealtimes.
These tips might be surprising, but they're based on sound science and research. Incorporating them into your regular, ongoing dental care, could increase your chances of healthy teeth and gums.
