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!
Braces are a common experience among teens and pre-teens. And although the treatment can be a major financial undertaking, more and more families pursue it to help their child attain a straighter, more attractive smile.
But orthodontics isn’t first and foremost a cosmetic treatment. Although an improved appearance is a benefit, the main reason for treatment is therapeutic—it can improve your child’s current and future dental health.
The teeth’s relationship to the jaws and gums makes moving them possible. Rather than simply being fixed within their jawbone socket, teeth are actually held in place by a strong, elastic tissue called the periodontal ligament. The ligament lies between the teeth and jawbone and attaches to both with tiny extending fibers. This attachment secures the teeth in place.
But the ligament also has a dynamic quality—it can reshape itself when necessary and allow teeth to move gradually into new positions. This is most necessary during the early years of mouth and jaw development, but it can also occur throughout life. Orthodontics takes advantage of this mechanism by applying precise pressure to the teeth in the direction of desired movement. The periodontal ligament does the rest by reshaping and allowing the teeth to move in response to this pressure.
The result is straighter teeth and a more normal bite. With the teeth now where they should be, it’s also easier to clean them of disease-causing dental plaque, whereas misaligned teeth are more prone to plaque accumulation that can be difficult to remove. And because the whole mouth including teeth are involved when we talk, teeth positioned in a more normal bite will improve speech.
Orthodontics is a long-term process, often encompassing more than the actual time wearing braces. Both orthodontists and pediatric dentists recommend a bite evaluation by an orthodontist around the age of 6. If it does appear an abnormal bite is forming, it may be possible to intervene and stop or at least slow the development. This could have a more positive impact on any future treatment.
Braces and other treatments can make a difference in your child’s self-image and social relationships. But the main beneficiary will be their dental health.

Think you're too old to have your teeth straightened? While we automatically pair “teenager” with “braces,” at least one in five orthodontic patients are adults. And there's many more that could benefit, as many as three-quarters of adults with a correctable bite problem.
But although orthodontics can be performed at any age, it's not a minor undertaking. It will require time, patience and expense. So, before you decide to undergo orthodontics, here are 3 simple questions to ask first.
Why? Like children and teenagers, adults can benefit cosmetically from correcting a poor bite. But there's another great reason besides a more attractive smile: misaligned teeth are more difficult to care for than normal teeth. Orthodontic treatment is an investment and potential cost-saver in your future dental health.
Why not? Even senior adults can successfully undergo treatment. But braces might be ill-advised if you have either poor oral or general health. Periodontal (gum) disease, for example, can cause bone loss, which makes it difficult to safely and successfully move teeth (and the effort could worsen current disease activity in the gums). Medical conditions like bleeding disorders, leukemia or uncontrollable diabetes could interfere as well. You'll need both a dental and medical examination beforehand.
How? We can use braces — or we might be able to use a newer, more popular option with adults called clear aligners. These are a series of computer-designed clear, plastic trays you wear in sequence until you finish the series. Each tray is slightly smaller than the previous tray, moving the teeth in much the same manner as braces. But unlike braces, you can remove aligners for cleaning or a rare special occasion — and they're much less noticeable than metal braces. Although in some cases braces may still be the best option, it's also possible clear aligners could be the option you've been looking for.
So, are you ready for a new smile and a more maintainable mouth? Visit us for the answers to your questions and see if braces (or clear aligners) can transform your life and health.
