With smart phone in hand, you can instantaneously find out just about anything. Unfortunately, online search results aren’t always accurate. Case in point: there’s an idea floating on the World Wide Web that root canal treatments cause cancer.
Sounds ludicrous? Yes, but like other strange ideas this one has historical roots (pardon the pun). In the early 20th Century, a dentist named Weston Price propagated the idea that leaving a “dead” organ in the body caused health problems. By his view, a root canal-treated tooth fell into this category and could potentially cause, among other things, cancer.
But concern over root canal treatment safety is on shaky ground: dentistry examined Dr. Price’s ideas over sixty years ago and found them wanting. But first, let’s look at what a root canal treatment can actually do for your health.
Tooth decay is an infection that first attacks the outer tooth enamel and then continues to advance until it infects the inner pulp. It can then travel through the root canals to the roots and bone. Without intervention, the infection will result in tooth loss.
We use a root canal treatment to save the tooth from this fate. During the procedure we remove and disinfect all of the diseased or dead tissue within the pulp and root canals. We then fill the empty chamber and canals with a special filling and seal the tooth to prevent any further infection. And while technically the procedure renders a tooth unable to respond to thermal sensitivity or tooth decay, the tooth is still alive as it is attached to the periodontal ligament and its blood supply and nerve tissue. The tooth can still “feel” if you bite on something too hard and it doesn’t affect the tooth’s function or health, or a patient’s overall health for that matter.
As to Dr. Price’s theory, extensive studies beginning in the 1950s have examined the potential health risk of root canal treatments. The latest, a 2013 patient survey study published in a journal of the American Medical Association, not only found no evidence linking root canal treatment to cancer, but a lower risk of oral cancer in 45% of patients who had undergone multiple root canal treatments.
While root canal treatments do have potential side effects, none are remotely as serious as this online “factoid” about cancer. It’s far more likely to benefit your health by saving your tooth.

When it comes to our children’s safety, there isn’t much nowadays that isn’t under scrutiny. Whether food, clothing, toys and more, we ask the same question: can it be harmful to children?
That also includes tried and true healthcare practices. One in particular, the routine x-ray, has been an integral part of dental care for nearly a century. As a means for detecting tooth decay much earlier than by sight, it has without a doubt helped save billions of teeth.
But is it safe for children? The reason to ask is because x-rays are an invisible form of electromagnetic radiation that can penetrate human tissue. As with other forms of radiation, elevated or frequent exposure to x-rays could damage tissue and increase the future risk of cancer.
But while there is potential for harm, dentists take great care to never expose patients, especially children, to that level or frequency of radiation. They incorporate a number of safeguards based on a principle followed by all healthcare professionals in regard to x-rays called ALARA, an acronym for “as low as reasonably achievable.” This means dentists and physicians use as low an exposure of x-ray energy as is needed to achieve a reasonable beneficial outcome. In dentistry, that’s identifying and treating tooth decay.
X-ray equipment advances are a good example of ALARA in action. Digital imaging, which has largely replaced film, requires less x-ray radiation for the same results than its older counterpart. Camera equipment has also become more efficient, with modern units containing lower settings for children to ensure the proper amount of exposure.
Dentists are also careful how often they take x-ray images with their patients, only doing so when absolutely necessary. As a result, dental patients by and large experience lower dosages of x-ray radiation in a year than they receive from natural radiation background sources found every day in the environment.
Dentists are committed to using x-ray technology in as safe and beneficial a way as possible. Still, if you have concerns please feel free to discuss it further with your dental provider. Both of you have the same goal—that your children have both healthy mouths and healthy bodies for the rest of their lives.

Although tooth decay is a major problem to watch for in your child’s teeth, it isn’t the only one. As their teeth transition from primary (“baby”) to permanent, you should also be on the lookout for a developing poor bite or malocclusion.
Although the signs can be subtle, you may be able to detect an emerging malocclusion, starting usually around age 6, if you know what to look for. Here are 4 signs your child may be developing a poor bite.
Excessive spacing. This is something that might be noticeable while the child still has their primary teeth. If you notice an excessive amount of space around the front teeth, the sizes of the jaws and the teeth may be disproportional.
Abnormal overlapping. The upper teeth normally just cover the bottom teeth when the jaws are closed. But a malocclusion may be forming if the lower teeth cover the upper (underbite), the upper teeth extend too far over the lower (deep bite) or there’s space between the upper and lower front teeth (open bite).
Different overlapping patterns. Watch as well for some of the teeth overlapping normally while others don’t, a sign of a cross bite. For example, the back upper teeth may cover their counterparts in a normal fashion while the lower front teeth abnormally overlap the top front. The roles here between front and back teeth can also be reversed.
Abnormal eruptions. Permanent teeth normally follow a pattern when erupting, but certain factors could disrupt the process. For example, a jaw that’s developed too small can cause crowding as incoming teeth vie for space; as a result, some permanent teeth may erupt out of their proper position. Likewise, if a baby tooth is out of its normal position or prematurely lost, the permanent tooth may erupt out of position too.
The good news with each of these developing bite problems is that we can correct them or at least minimize their future effect if caught early. So if you notice any of these signs or anything else out of the ordinary, see an orthodontist as soon as possible. It’s also a good idea to have your child undergo a thorough orthodontic evaluation around age 6.

For anyone else, having a tooth accidentally knocked out while practicing a dance routine would be a very big deal. But not for Dancing With The Stars contestant Noah Galloway. Galloway, an Iraq War veteran and a double amputee, took a kick to the face from his partner during a recent practice session, which knocked out a front tooth. As his horrified partner looked on, Galloway picked the missing tooth up from the floor, rinsed out his mouth, and quickly assessed his injury. “No big deal,” he told a cameraman capturing the scene.
Of course, not everyone would have the training — or the presence of mind — to do what Galloway did in that situation. But if you’re facing a serious dental trauma, such as a knocked out tooth, minutes count. Would you know what to do under those circumstances? Here’s a basic guide.
If a permanent tooth is completely knocked out of its socket, you need to act quickly. Once the injured person is stable, recover the tooth and gently clean it with water — but avoid grasping it by its roots! Next, if possible, place the tooth back in its socket in the jaw, making sure it is facing the correct way. Hold it in place with a damp cloth or gauze, and rush to the dental office, or to the emergency room if it’s after hours or if there appear to be other injuries.
If it isn’t possible to put the tooth back, you can place it between the cheek and gum, or in a plastic bag with the patient’s saliva, or in the special tooth-preserving liquid found in some first-aid kits. Either way, the sooner medical attention is received, the better the chances that the tooth can be saved.
When a tooth is loosened or displaced but not knocked out, you should receive dental attention within six hours of the accident. In the meantime, you can rinse the mouth with water and take over-the-counter anti-inflammatory medication (such as ibuprofen) to ease pain. A cold pack temporarily applied to the outside of the face can also help relieve discomfort.
When teeth are broken or chipped, you have up to 12 hours to get dental treatment.Â Follow the guidelines above for pain relief, but don’t forget to come in to the office even if the pain isn’t severe. Of course, if you experience bleeding that can’t be controlled after five minutes, dizziness, loss of consciousness or intense pain, seek emergency medical help right away.
And as for Noah Galloway:Â In an interview a few days later, he showed off his new smile, with the temporary bridge his dentist provided… and he even continued to dance with the same partner!

Over the last century effectively treating a decayed tooth has often required removing any decayed structure with drilling and then filling the remaining cavity. While this approach does save teeth that might otherwise be lost, it can also result in a fair amount of healthy structure removed in the process.
But continuing advances in dentistry are now making possible a new approach to tooth decay treatment that preserves as much of the healthy portions of tooth as possible. This new way is often referred to as minimally invasive dentistry (MID).
The primary goal of MID treatment is to intercept and treat decay as early as possible to minimize tooth damage. It begins with helping patients identify their own individual risk factors for decay such as the presence of disease-causing bacteria, the adequacy of their saliva flow, or their lifestyle and dietary habits. We then recommend changes or preventive measures to reduce those risks.
The next step in MID is using various diagnostic technologies to find decay as early as possible. X-rays continue to play a major role, but dentists are also using dental microscopy to magnify the earliest forms of decay. Many also utilize laser fluorescence, infrared photography and optical scanning to further “see” decay difficult to detect with the naked eye.
In regard to treatments, MID adopts the adage “less is more.” If caught early enough, we can encourage the re-mineralization of enamel that acid has eroded with CPP-ACP, a substance acquired from milk, or strengthen teeth with topical fluoride applications. Instead of the dental drill, many dentists now turn to air abrasion for decay removal, equipment that emits a fine stream of abrasive particles that harms less healthy structure than a drill.
And if lasers continue to develop at their current pace, we’ll be able to use this technology to perform much more precise decay treatment than possible with manual instruments. As a result, we’ll be able to treat decayed teeth with less invasive means to preserve as much healthy structure as possible.
As these and other developments continue, MID promises a bright future for preventing and treating tooth decay. As a result, there’ll be less tooth structure loss and more attractive and healthy smiles.
