Thanks to treatments like chemotherapy and radiation, your chances of surviving cancer are greater than ever. These treatments, however, often produce unwelcome side effects. Treating throat or oral cancer, for example, could damage your mouth's salivary glands or bone.
Saliva is essential to oral health, providing antibodies to curb the growth of disease-causing bacteria and neutralizing acid, which can erode enamel. But salivary glands damaged during cancer treatment may not be able to produce enough saliva. The resulting “dry mouth” creates an environment conducive to bacterial growth and elevated acid levels.
You can help reduce the effects of dry mouth during your treatment (and after, if the damage is permanent) by drinking more water or by using substances that stimulate saliva. Cutting back on acidic foods and beverages will also help lower your mouth's acidity. And be sure to keep up daily oral hygiene and regular dental visits.
The more ominous threat to oral health during cancer treatment, though, is osteoradionecrosis. This occurs when radiation targets specific areas of bone. The bone can lose blood supply and living cellular tissue, which inhibit its ability to heal or replenish itself. If this occurs in the jawbone of teeth that may be lost, the bone tissue could be adversely affected during healing.
Depending on your treatment needs, your risk for osteoradionecrosis might be unavoidable if teeth are to be lost. It's important we discuss that risk because it could impact future dental treatment. In the worst case, before cancer treatment, we may not be able to save affected teeth and your restorative options might be limited.
If your risk of osteoradionecrosis is minimal, though, we may be able to restore any resulting damaged or missing teeth with a wide range of options like dental implants or crowns before or after your cancer treatment.
As with other aspects of health, taking care of your teeth and gums while undergoing cancer treatment can be challenging; some problems may be unavoidable. But with a proper dental treatment plan during and after chemotherapy and radiation, we can minimize those problems and help to eventually restore your smile.
In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.
