X-ray imaging is such an intricate part of dentistry, we usually don't think twice about it. Without it, though, the fight against dental disease would be much harder.
At the same time, we can't forget that x-rays are a form of electromagnetic radiation that can penetrate human tissue. It's that very quality and the difference in the absorption rate between denser bone and teeth and softer diseased tissue that makes disease diagnosis possible.
But this same penetrative power can potentially harm the tissues it passes through. For that reason when practicing any form of x-ray diagnostics, dentists follow a principle known as ALARA, an acronym for "As Low As Reasonably Achievable." In lay terms ALARA means getting the most benefit from x-rays that we can with the lowest dose and exposure time possible.
While practicing ALARA with x-rays is important for patients of any age, it's especially so for children who are more sensitive to radiological energy given their smaller size and anatomy. We can't use the same settings, dosages or exposure times with them as with an adult.
To protect children, dentists have developed techniques and protocols that lessen their exposure time and rate, while still providing usable images for diagnosing disease. The bitewing is a good example of safe and effective pediatric x-ray imaging.
A bitewing is a plastic device holding exposable film that patients bite down on and hold in their mouth while x-raying. The x-rays pass through the teeth and gums and expose the film behind them on the bitewing. Using a bitewing we can capture a set of two to four radiographs to give us a comprehensive view of the back teeth, while exposing the child less radiation than they normally receive daily from background environmental sources.
This and other advances in equipment and digital imaging greatly reduce the amount of radiation patients receive during x-rays. If, though, you're still concerned about your child's x-ray exposure, talk with your dentist who can explain in more detail the x-ray safety protocols they follow. Just like you, they want your child to be as safe as possible while still benefiting from the diagnostic power of x-rays.

April brings the perfect weather to get outside and play. Fittingly, April is also National Facial Protection Month. Whether you prefer softball or basketball, skateboarding or ultimate frisbee, don't forget your most important piece of equipment: a mouthguard to protect your face and your smile!
In an instant, a blow to the mouth can cause a dental injury that is painful to endure and expensive to treat. In just about any sporting activity, your mouth could come into contact with a piece of equipment, another person or the ground. That's why the American Dental Association and the Academy for Sports Dentistry recommend using a mouthguard when participating in any of over 30 activities, including some that aren't typically considered contact sports, like volleyball and bike riding.
Common sense, observation and scientific research support the use of mouthguards during sporting activities—but are the ones you get from your dentist really any better than the kind you can grab off the shelf at a sporting goods store or drugstore? The answer is yes!
In a 2018 experiment, researchers created a model of the human head to test how direct impact affects the teeth, jaws and skull. They compared the effects of impact when using no mouthguard, when using a custom-made mouthguard available from the dentist, and when using a stock mouthguard. They also tested mouthguards of different thicknesses. The results? The experimenters determined that any mouthguard is better than no mouthguard and that custom mouthguards available from the dental office are more effective than off-the-shelf mouthguards in protecting teeth, jaws and skull from impact. They also found that the thicker the mouthguard, the better the protection.
Although custom mouthguards are more expensive than the kind you can buy at the corner store, the difference in protection, durability, comfort and fit is well worth the investment. We consider your (or your child's) individual needs, take a precise model of your mouth and provide you with a custom-fit mouthguard of the highest quality material.
Don't ruin your game. A mouthguard can go a long way in protecting your teeth and mouth from injury.

Proponents of legalized marijuana have won phenomenal gains over the last decade. Despite the federal government's continuing criminalization of the drug, several states including California, Colorado and Massachusetts, have voted to legalize its recreational use.
Most people are aware of the social and political controversies the marijuana legalization movement stirs. But there's another side to this roiling issue: the health effects of marijuana, particularly for your teeth and gums. What may be lost beneath the more exciting headlines about ballot initiatives is the growing evidence that habitual marijuana use may increase the risk and severity of periodontal (gum) disease.
Gum disease is a bacterial infection caused by dental plaque, a thin film of bacteria and food particles that accumulates on teeth. The spreading infection triggers inflammation, a normal bodily response to disease that's ordinarily beneficial. But if the inflammation becomes chronic it weakens the gums' attachment to the teeth. This can create voids or periodontal pockets of infection around the teeth. The disease can eventually damage the underlying bone, which could accelerate tooth loss.
Poor oral hygiene is the biggest factor for an increased risk of gum disease; thinner gum tissue (an inherited condition or related to poor tooth position) is another factor, as well as lifestyle habits like tobacco use or excessive alcohol consumption. Add marijuana to the list: there's now some evidence that its use increases the risk for more severe periodontal pockets if the disease occurs.
In a recent study, researchers with the Columbia University College of Dental Medicine reviewed statistics on the care for nearly 2,000 adult patients; a quarter of those in the study were frequent marijuana users. The marijuana users proportionately had deeper periodontal pocket occurrences than the rest of the patients in the study that didn't use the drug.
The study doesn't say that marijuana causes periodontal (gum) disease. But it does suggest that marijuana use might increase its severity. As with other substances and practices in our society, marijuana use comes with a caveat: it may be legal where you live, but it may not necessarily be good for your health.

Around 20 million people—mostly women after menopause—take medication to slow the progress of osteoporosis, a debilitating disease that weakens bones. But although effective, some osteoporosis drugs could pose dental issues related to the jawbones.
Osteoporosis causes the natural spaces that lie between the mineral content of bone to grow larger over time. This makes the bone weaker and unable to withstand forces it once could, which significantly increases the risk of fracture. A number of drugs have been developed over time that stop or slow this disease process.
Two of the most prominent osteoporosis drugs are alendronate, known also by its trade name Fosamax, and denosumab or Prolia. While originating from different drug families, alendronate and denosumab work in a similar way by destroying specialized bone cells called osteoclasts that break down worn out bone and help dissolve it. By reducing the number of these cells, more of the older bone that would have been phased out lasts longer.
In actuality this only offers a short-term benefit in controlling osteoporosis. The older bone isn’t renewed but only preserved, and will eventually become fragile and more prone to fracture. After several years the tide turns negatively for the bone’s overall health. It’s also possible, although rare, that the bone simply dies in a condition called osteonecrosis.
The jawbones are especially susceptible to osteonecrosis. Forces generated by chewing normally help stimulate jawbone growth, but the medications in question can inhibit that stimulus. As a result the jawbone can diminish and weaken, making eventual tooth loss a real possibility.
Osteonecrosis is most often triggered by trauma or invasive dental procedures like tooth extractions or oral surgery. For this reason if you’re taking either alendronate and denosumab and are about to undergo a dental procedure other than routine cleaning, filling or crown-work, you should speak to your physician about suspending your medication temporarily. Dentists often recommend a suspension of three to nine months before the procedure and three months afterward.
Some research indicates this won’t worsen your osteoporosis symptoms, especially if you substitute another treatment or fortify your skeletal system with calcium and vitamin D supplements. But taking this temporary measure could help protect your teeth in the long run.

“What can I do about my child's teeth grinding habit?”
It's a common question we get from many concerned parents. Their exasperation involves more than having to wake every night to the annoying sounds coming from their child's bedroom: they're also worried about any potential damage occurring to their teeth.
Teeth grinding and similar habits fall under the umbrella term “bruxism.” In basic terms, bruxism is the involuntary movement of the teeth and jaws not engaged in regular functions like chewing, speaking or swallowing. Bruxism is actually common among pre-adolescent children, considered by many healthcare professionals as normal behavior like thumb sucking.
It's not fully known why children grind their teeth, especially during sleep. Stress can play a part, but many believe it could also be related to immaturity on the part of the neuromuscular system that controls chewing. In some cases it could be linked to sudden arousals from sleep, particularly if the child is prone to airway obstruction causing sleep apnea. And there may be a link with certain medications, especially for hyperactivity disorders like attention deficit hyperactivity disorder (ADHD).
Most children eventually outgrow the habit. If it persists, though, it can contribute to teeth problems. Teeth can withstand a lot of biting force, but when chronically exposed to the higher than normal forces produced during teeth grinding they can begin to wear. Sodas, fruit juices, sports drinks or similar acidic beverages complicate matters because they increase mouth acid that can soften enamel. And besides dental issues, teeth grinding can also cause jaw problems, ear pain and headaches.
If symptoms begin to appear, we can take steps to reduce the effect of teeth grinding, such as a mouth guard worn at night to reduce biting forces and protect against wear. We can also look at curbing consumption of acidic foods and beverages, addressing possible airway obstructions, changing medications or counseling for psychological stress.
As with thumb sucking, there's no cause for immediate alarm if your children grind their teeth. But if it continues on into their later childhood years or begins to affect their health and well-being, we'll need to intervene to prevent further harm.
