It’s important for your child’s current and future health that we watch out for tooth decay. Taking x-rays is a critical part of staying one step ahead of this common disease.
But while x-ray imaging is commonplace, we can’t forget it’s still a form of radiation that could be potentially harmful, especially for a child whose tissues are rapidly developing. We must, therefore, carefully weigh the potential benefits against risk.
This concern has given birth to an important principle in the use of x-rays known as ALARA, an acronym for “As Low As Reasonably Achievable.” In basic terms, we want to use the lowest amount of x-ray energy for the shortest period of time to gain the most effectiveness in diagnosing tooth decay and other conditions.
A good example of this principle is a common type of radiograph known as a bitewing. The exposable x-ray film is attached to a plastic devise that looks like a wing; the patient bites down on it to hold it in place while the x-ray exposure takes place. Depending on the number of teeth in a child’s mouth, an appointment usually involves 2 to 4 films, and children are typically spaced at six months apart. Frequency of x-rays depends on your child’s tooth decay risk: lower risk, less need for frequent intervals.
Each bitewing exposes the child to 2 microsieverts, the standard unit for radiation measurement. This amount of radiation is relatively low: by contrast, we’re all exposed to 10 microsieverts of background radiation (natural radiation occurring in the environment) every day or 3,600 microsieverts annually. Even two appointments of four bitewings each year is a fraction of a percent of the background radiation we’re exposed to in the same year.
This conservative use of x-rays is well within safe parameters for children. As x-ray technology continues to advance (as with the development of digital imaging) we anticipate the exposure rate to diminish even more. Prudently used, x-rays remain one of our best tools for ensuring your child’s teeth are healthy and developing normally.

There's a burning sensation in your mouth even though you haven't had anything hot to eat or drink. It's an experience you've had for years, often accompanied by mouth dryness, tingling or numbness that leaves you irritable, anxious or depressed.
The root causes for Burning Mouth Syndrome (BMS) remain elusive, although there appear to be links to diabetes, acid reflux, menopausal hormonal changes or even psychological issues. Although we may not be able to pinpoint the root cause we can identify contributing factors to BMS through a detailed oral examination and medical history (including drugs you're taking).
Mouth dryness is one of the most common factors for BMS. The lack of lubrication from adequate saliva flow can contribute substantially to the irritating burning sensation. There are a number of causes for mouth dryness, including as a side effect from many medications or other treatments.
We must also consider whether an allergic reaction — the body's over-reaction to a foreign substance — may have a role in your symptoms. Some people react to sodium lauryl sulfate, a foaming agent found in many types of toothpaste, along with whitening substances or flavorings like cinnamon; denture wearers can become allergic to the plastic materials used to construct the denture. These, as well as spicy foods, smoking or alcohol, can irritate or cause the tissues lining the inside of the mouth to peel.
Determining what factors contribute to your symptoms allows us to develop a treatment approach tailored to your situation. If, for example, we've determined your BMS stems from dry mouth as a side effect to medication, we can ask your doctor to prescribe an alternative, increase your water intake when taking pills or stimulate saliva flow. If we identify an allergen as a factor, you can eliminate the substance to reduce symptoms.
You may also need to make changes to your eating and lifestyle habits: stop smoking, reduce your alcohol or coffee consumption and avoid very hot or spicy foods. And look for ways to reduce stress, another contributing factor, through relaxation techniques, exercise or support groups.
It's possible that BMS will resolve itself over time. In the meantime, though, we can help you find ways to alleviate the irritation.

Even though teeth are resilient, they're not indestructible. An accidental collision involving the face could damage teeth, even knocking a tooth completely out of its socket.
At first, it might seem like the end of the line for that particular tooth. But it doesn't have to be—if you know what to do. But you'll have to act quickly: The longer the tooth is out of its socket, the less chance it will survive long-term.
Here are the steps you should take to save a knocked-out tooth.
Find the tooth. It's important that you locate the missing tooth quickly. When you do, don't handle it by the root end: It still contains delicate periodontal cells that are essential if the tooth is going to rejoin with the ligaments and bone. Use clean water to rinse off any dirt or debris.
Reinsert the tooth. Holding it by the crown and not the root, reinsert the tooth into its empty socket, hopefully within an hour (the faster the better). You want to make sure it's good and snug, so apply a little force when you do this. Place some clean gauze or cloth between the tooth and its opposite on the other jaw, then have the person bite down and hold it in place.
Get immediate dental care. It's preferable to find a dentist as soon as possible (if not, then the nearest emergency medical facility). The dentist will x-ray the tooth to make sure it's positioned properly, and may adjust it further if necessary. They may also splint the tooth to adjacent teeth to help stabilize it until it fully reattaches with the jaw.
Again, time is of the essence—the quicker you can perform the above steps, the better the tooth's chances. Any delay could jeopardize the tooth's ability to reattach, or it could shorten its lifespan.
