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.

The long-running hit show Dancing with the Stars has had its share of memorable moments, including a wedding proposal, a wardrobe malfunction, and lots of sharp dance moves. But just recently, one DWTS contestant had the bad luck of taking an elbow to the mouth on two separate occasions—one of which resulted in some serious dental damage.
Nationally syndicated radio personality Bobby Bones received the accidental blows while practicing with his partner, professional dancer Sharna Burgess. “I got hit really hard,” he said. “There was blood and a tooth. [My partner] was doing what she was supposed to do, and my face was not doing what it was supposed to do.”
Accidents like this can happen at any time—especially when people take part in activities where there’s a risk of dental trauma. Fortunately, dentists have many ways to treat oral injuries and restore damaged teeth. How do we do it?
It all depends on how much of the tooth is missing, whether the damage extends to the soft tissue in the tooth’s pulp, and whether the tooth’s roots are intact. If the roots are broken or seriously damaged, the tooth may need to be extracted (removed). It can then generally be replaced with a dental bridge or a state-of-the-art dental implant.
If the roots are healthy but the pulp is exposed, the tooth may become infected—a painful and potentially serious condition. A root canal is needed. In this procedure, the infected pulp tissue is removed and the “canals” (hollow spaces deep inside the tooth) are disinfected and sealed up. The tooth is then restored: A crown (cap) is generally used to replace the visible part above the gum line. A timely root canal procedure can often save a tooth that would otherwise be lost.
For moderate cracks and chips, dental veneers may be an option. Veneers are wafer-thin shells made of translucent material that go over the front surfaces of teeth. Custom-made from a model of your smile, veneers are securely cemented on to give you a restoration that looks natural and lasts for a long time.
It’s often possible to fix minor chips with dental bonding—and this type of restoration can frequently be done in just one office visit. In this procedure, layers of tooth-colored resin are applied to fill in the parts of the tooth that are missing, and then hardened by a special light. While it may not be as long-lasting as some other restoration methods, bonding is a relatively simple and inexpensive technique that can produce good results.

May is National Save Your Tooth Month, and tooth decay is a leading cause of lost teeth. It all begins with oral bacteria growing rapidly in built-up deposits of dental plaque, and in turn producing high levels of acid. At these levels, acid can erode the minerals in tooth enamel to create holes (“cavities”) that allow bacteria to enter the tooth and infect it.
If at all possible, we need to try to stop tooth decay early by disinfecting and filling these cavities. If not, decay can spread through the teeth to the underlying nerve (pulp) tissue, following passageways known as root canals. If this happens, the chances for saving the tooth are extremely low.
But if the decay does reach the tooth’s innermost layer—the pulp—filling the cavities won’t be enough. Decay this advanced requires a procedure known as root canal therapy, or a root canal for short.
If you winced a little, it’s understandable: Root canals have gained an unfair reputation as an unpleasant experience. In reality, a root canal performed by a skilled dentist or endodontist (a specialist in root canals) isn’t painful. In fact, if you come in with a painful tooth, you’re very likely to leave after the procedure without any pain.
Root canal procedures can vary depending on the type of tooth and the intricacy of its root canal network. Essentially, though, we remove the diseased pulp tissue, and then clean and fill the empty pulp chamber and root canals. This stops the infection and, along with sealing and crowning the tooth, helps prevent a future re-infection.
How do you know if you need a root canal? You may find out from us if we discover advanced decay during a checkup or cleaning appointment. But you may encounter signs yourself like a throbbing toothache, pain during and after eating and drinking, or gum tenderness around a tooth. These are all possible indications of tooth decay.
If you experience any of these signs, you should see us as soon as possible for an examination. And don’t cancel your appointment if the pain goes away—this could simply mean the nerves in the pulp have died and are no longer transmitting pain signals. The infection, though, could still be there and continuing its rampage beyond the tooth and into the surrounding bone tissue.
Root canal therapy may not seem glamorous, but it’s an excellent option for a diseased tooth that would otherwise have to be removed. A root canal could get rid of your pain and give your troubled tooth a new lease on life!

A loose adult tooth isn't normal. It could be loose because it's been subjected to high biting forces like those that occur with a tooth grinding habit. Or, it could be the result of periodontal (gum) disease or some other infection that has weakened some of the tooth's supporting gums and bone. Whatever the underlying cause, we'll need to act quickly to save your tooth.
Our first step is to find out this exact cause—that will determine what treatment course we need to follow. For a tooth grinding habit, for example, you might need to wear an occlusal guard or have your bite (teeth) adjusted. With gum disease, we'll focus on removing dental plaque, the thin film of bacteria and tartar (calculus) fueling the infection. This stops the infection and minimizes any further damage.
While we're treating the cause, we may also need to secure the loose tooth with splinting. This is a group of techniques used to join loose teeth to more stable neighboring teeth, similar to connecting pickets in a fence. Splinting can be either temporary or permanent.
Temporary splinting usually involves composite materials with or without strips of metal to bond the loose tooth to its neighbors as the periodontal structures heal. Once the tooth's natural attachments return to health, we may then remove the splint.
There are a couple of basic techniques we can use for temporary splinting. One way is to bond the splint material to the enamel across the loose tooth and the teeth chosen to support it (extra-coronal splinting). We can also cut a small channel across all the affected teeth and then insert metal ligatures and bond the splint material within the channel (intra-coronal).
If we're not confident the loose tooth will regain its natural gum attachment, we would then consider a permanent splint. The most prominent method involves crowning the loose tooth and supporting teeth with porcelain crowns. We then fuse the crowns together to create the needed stability for the loose teeth.
Whatever splinting method we use, it's important to always address the root cause for a tooth's looseness. That's why splinting usually accompanies other treatments. Splinting loose teeth will help ensure your overall treatment is successful.

The longer many health problems go on, the worse they become. Treating them as early as possible could stop or slow their development.
That holds true for poor bites: while we can certainly correct them later in life, it's often better to "intercept" the problem during childhood. Interceptive orthodontics attempts to do this with treatments that influence how the jaws and other mouth structures develop during childhood. Many of these techniques are usually best implemented before puberty.
For example, some very complex problems called cross bites can occur if the upper jaw grows too narrowly. We might be able to stop this from happening by using an orthodontic appliance called a palatal expander during the childhood years. It works because the bone at the center of the palate (roof of the mouth) has a gap running back to front until the early teens when the gap closes.
We fit the palatal expander up under and against the palate, then extend out metal arms from a center mechanism to the back of the upper teeth that exert outward pressure on them. This widens the center gap, which the body continually fills with bone as the device gradually exerts more pressure. Over time this causes the jaw to widen and lessens the cross bite. Timing, though, is everything: it's most effective before the gap closes.
Another way to aid jaw growth is a Herbst appliance, a hinged device that alters the movement of the jaws. As a child wears it, a Herbst appliance draws the lower jaw forward to develop more in that direction. Like the palatal expander, it's best used before significant jaw growth occurs.
These are just two examples of techniques and tools that can guide structural growth and prevent bite problems. Because they're most effective in the early years of oral development, your child should undergo an orthodontic evaluation as early as age 6 to see if they need and can benefit from an interceptive treatment.
Interceptive orthodontics can stop or at least slow a growing bite problem. The effort and expense now could save you much more of both later on.
