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.

If you have a few missing teeth but can't afford dental implants or fixed bridgework, consider a removal partial denture (RPD). Although implants may be the superior choice aesthetically and functionally, an RPD can still effectively give you back your teeth.
RPDs are designed to replace one or more missing teeth but not a full arch like a full denture. Considered a permanent restoration, RPDs are also more durable than transitional "flippers," denture appliances that are flexible and light enough to be flipped out of the mouth with a flick of the tongue.
The key to both their affordability and durability is vitallium, a strong but lightweight metal alloy most often used in their frame construction. To it we attach artificial teeth usually made of porcelain or glass-filled resins that occupy the precise location of the missing teeth on the gum ridge. The artificial teeth and frame are surrounded by gum-colored plastic for a more natural look.
Each RPD is custom-made depending on the number and location of the missing teeth. Its construction will focus on minimizing any rocking movement of the RPD during chewing or biting. Too much of this movement could damage the adjacent teeth it's attaching to and cause the appliance to be uncomfortable to wear. We can stabilize the frame by precisely fitting it between teeth to buttress it. We also insert small rests or clasps made of vitallium at strategic points to grip teeth and minimize movement.
RPDs do have some downsides: their unique attachment with teeth encourages the accumulation of dental plaque, the thin bacterial film that's the leading cause of tooth decay and periodontal (gum) disease. These diseases can affect your remaining teeth's health and stability, which could in turn disrupt the fit of the RPD. Also, too much movement of the appliance can make the teeth to which it's attached become more mobile. It's important, then, if you wear a RPD to remove it daily for cleaning (and to thoroughly brush and floss your natural teeth), and to remove it at night to give the attaching teeth a rest.
A RPD can give you back the teeth you've lost for many years to come—if you take care of it. Maintaining both your RPD and the rest of your teeth and gums will help extend the life and use of this effective and affordable replacement restoration.

On the big screen, Australian-born actress Margot Robbie may be best known for playing devil-may-care anti-heroes—like Suicide Squad member Harley Quinn and notorious figure skater Tonya Harding. But recently, a discussion of her role in Peter Rabbit proved that in real life, she’s making healthier choices. When asked whether it was hard to voice a character with a speech impediment, she revealed that she wears retainers in her mouth at night, which gives her a noticeable lisp.
“I actually have two retainers,” she explained, “one for my bottom teeth which is for grinding my teeth, and one for my top teeth which is just so my teeth don't move.”
Clearly Robbie is serious about protecting her dazzling smile. And she has good reasons for wearing both of those retainers. So first, let’s talk about retainers for teeth grinding.
Also called bruxism, teeth grinding affects around 10 percent of adults at one time or another, and is often associated with stress. If you wake up with headaches, sore teeth or irritated gums, or your sleeping partner complains of grinding noises at night, you may be suffering from nighttime teeth grinding without even being aware of it.
A type of retainer called an occlusal guard is frequently recommended to alleviate the symptoms of bruxism. Typically made of plastic, this appliance fits comfortably over your teeth and prevents them from being damaged when they rub against each other. In combination with stress reduction techniques and other conservative treatments, it’s often the best way to manage teeth grinding.
Orthodontic retainers are also well-established treatment devices. While appliances like braces or aligners cause teeth to move into better positions, retainers are designed to keep teeth from moving—helping them to stay in those positions. After active orthodontic treatment, a period of retention is needed to allow the bite to stabilize. Otherwise, the teeth can drift right back to their old locations, undoing the time and effort of orthodontic treatment.
So Robbie has the right idea there too. However, for those who don’t relish the idea of wearing a plastic appliance, it’s often possible to bond a wire retainer to the back surfaces of the teeth, where it’s invisible. No matter which kind you choose, wearing a retainer can help keep your smile looking great for many years to come.
If you have questions about teeth grinding or orthodontic retainers, please contact our office or schedule a consultation. You can read more in the Dear Doctor magazine articles “Teeth Grinding” and “The Importance of Orthodontic Retainers.”
Periodontal (gum) disease can weaken gum attachment and cause bone deterioration that eventually leads to tooth loss. But its detrimental effects can also extend beyond the mouth and worsen other health problems like heart disease or diabetes.
While the relationship between gum disease and other health conditions isn't fully understood, there does seem to be a common denominator: chronic inflammation. Inflammation is a natural defense mechanism the body uses to isolate damaged or diseased tissues from healthier ones. But if the infection and inflammation become locked in constant battle, often the case with gum disease, then the now chronic inflammation can actually damage tissue.
Inflammation is also a key factor in conditions like heart disease and diabetes, as well as rheumatoid arthritis or osteoporosis. Inflammation contributes to plaque buildup in blood vessels that impedes circulation and endangers the heart. Diabetes-related inflammation can contribute to slower wound healing and blindness.
Advanced gum disease can stimulate the body's overall inflammatory response. Furthermore, the breakdown of gum tissues makes it easier for bacteria and other toxins from the mouth to enter the bloodstream and spread throughout the body to trigger further inflammation. These reactions could make it more difficult to control any inflammatory condition like diabetes or heart disease, or increase your risk for developing one.
To minimize this outcome, you should see a dentist as soon as possible if you notice reddened, swollen or bleeding gums. The sooner you begin treatment, the less impact it may have on your overall health. And because gum disease can be hard to notice in its early stages, be sure you visit the dentist regularly for cleanings and checkups.
The most important thing you can do, though, is to try to prevent gum disease from occurring in the first place. You can do this by brushing twice and flossing once every day to keep dental plaque, the main trigger for gum disease, from accumulating on tooth surfaces.
Guarding against gum disease will certainly help you maintain healthy teeth and gums. But it could also help protect you from—or lessen the severity of—other serious health conditions.

Gum disease, also known as periodontal disease, develops when the gum tissues become infected. If left untreated, gum disease can spread throughout the mouth and lead to tooth loss. Fortunately, several treatments methods exist for restoring the health of gums affected by this ailment. Read on to learn more about gum disease, and contact dentist Dr. Michael Tisdelle in Charlottesville, VA, if you are in need of treatment!
Causes of Gum Disease
Gum disease is caused by a bacterial infection, and generally from when bacteria gets trapped in the tiny crevices of teeth and lingers there for a long time. Lingering bacteria can lead to the development of plaque, tartar buildup, and gingivitis, which can all lead to the development of gum disease.
Gum Disease Signs
There are several symptoms that can be an indication of gum disease. It is important to see a dentist at our Charlottesville office as soon as possible if you develop any signs of possible gum disease, for seeking treatment early will help stop the gum disease from spreading. Signs of gum disease include:
- Gums that are red, tender, or swollen
- Gums that bleed when eating, brushing, or flossing
- Gums that are beginning to recede
- Loose or missing teeth
- Tooth pain and sensitivity
- Chronic bad breath
Treating Gum Disease
Some of the primary goals when treating gum disease include stopping gum disease from progressing, restoring the health of gum tissues, and preventing any tooth loss. There are many options available for treating gum disease, including:
- Gum Grafting — Involves replacing damaged gum tissue with healthy tissue from other areas of the mouth.
- Scaling and Root Planing — Involves a thorough cleaning to remove plaque and tartar from below the gum line.
- Periodontal Laser Treatment — Involves the use of lasers to remove unhealthy gum tissue.
- Periodontal Plastic Surgery — Involves reshaping of the gums to create a more pleasing appearance after the gums have been affected by gum disease.
Help is available if you have gum disease. At our Charlottesville, VA, office, our dentist can help determine which treatment options would be best for restoring the health of your gums. To schedule an appointment with Dr. Tisdelle, call the office at (434) 977-4101.
