As a cancer patient, you know how important radiation and chemotherapy are to overcoming the disease. But these treatments often come at a price to other aspects of your health, including your teeth and gums if the treatment target includes the head or neck regions.
Radiation and chemotherapy are effective because they target and destroy cancer cells. Unfortunately, they may also kill non-cancerous, healthy cells; in the mouth, for example, they can damage the cells in the salivary glands and disrupt their ability to produce adequate saliva flow, leading to xerostomia (dry mouth).
This could seriously affect your teeth’s protective enamel shell. As we eat or drink, our mouth’s pH level can become too acidic. Acid is your enamel’s primary enemy because it causes the minerals in the enamel to soften and dissolve (de-mineralization). Saliva neutralizes acid and replaces much of the enamel’s minerals.
Without adequate saliva flow, the enamel will tend to erode over time. You can further aggravate the situation if you routinely consume acidic foods and drinks, like sipping energy drinks or soda during the day. Once the enamel is gone it can’t be replaced naturally, and the teeth will be in serious danger of tooth decay and eventual loss of function and appearance.
To avoid these consequences you should take steps during cancer treatment to reduce your risk for xerostomia or other unhealthy mouth conditions: limit your consumption of acidic foods and beverages; use mouth rinses to counteract acidity and inhibit bacterial growth; and promote saliva flow through medication.
It may be, though, that enamel erosion and subsequent tooth damage is unavoidable. In this case, you may need to consider restorative options with artificial crowns or other cosmetic enhancements — not only to improve your appearance but also to protect your natural teeth from further damage.
Before considering the latter, you should undergo a complete dental examination to assess your condition and make sure you have adequate bone and gum support, and any dental disease under control. From here, we can go about restoring the attractive smile that may have faded during your battle with cancer.
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.

Magician Michel Grandinetti can levitate a 500-pound motorcycle, melt into a 7-foot-tall wall of solid steel, and make borrowed rings vanish and reappear baked inside bread. Yet the master illusionist admits to being in awe of the magic that dentists perform when it comes to transforming smiles. In fact, he told an interviewer that it’s “way more important magic than walking through a steel wall because you’re affecting people’s health… people’s confidence, and you’re really allowing people to… feel good about themselves.”
Michael speaks from experience. As a teenager, his own smile was enhanced through orthodontic treatment. Considering the career path he chose for himself — performing for multitudes both live and on TV — he calls wearing an orthodontic device (braces) to align his crooked teeth “life-changing.” He relies on his welcoming, slightly mischievous smile to welcome audiences and make the initial human connection.
A beautiful smile is definitely an asset regardless of whether you’re performing for thousands, passing another individual on a sidewalk or even, research suggests, interviewing for a job. Like Michael, however, some of us need a little help creating ours. If something about your teeth or gums is making you self-conscious and preventing you from smiling as broadly as you could be, we have plenty of solutions up our sleeve. Some of the most popular include:
- Tooth Whitening. Professional whitening in the dental office achieves faster results than doing it yourself at home, but either approach can noticeably brighten your smile.
- Bonding. A tooth-colored composite resin can be bonded to a tooth to replace missing tooth structure, such a chip.
- Veneers. This is a hard, thin shell of tooth-colored material bonded to the front surface of a tooth to change its color, shape, size and/or length; mask dental imperfections like stains, cracks, or chips, and compensating for excessive gum tissue.
- Crowns. Sometimes too much of a tooth is lost due to decay or trauma to support a veneer. Instead, capping it with a natural-looking porcelain crown can achieve the same types of improvements. A crown covers the entire tooth replacing more of its natural structure than a veneer does.
If you would like more information about ways in which you can transform your smile, please contact us or schedule an appointment for a consultation.
